[iPhone] UITableView cell display bugs ?
Hello, I'm trying to reuse (with some modifications) UITableViewCellStyleSubtitle cells, which have two left-aligned labels. I want to have both labels and add a right-aligned text field. All three views must be as wide as roughly half the available content view width. It should be a trivial task: just add the text field to the cell's content view, and resize all frames. The problem is that the detail text label is stubbornly obscuring the text field, even after being resized and sent to the back. (see attached picture) I realize that any frame adjustments must be done in -tableView: willDisplayCell: forRowAtIndexPath: rather than in the method that creates/reuses cells, but I wasn't expecting the order of content view subviews to change between those two methods. I verified that bringing the text field to the front in -tableView: cellForRowAtIndexPath: has no effect because the detail text label is brought to the front between that method and willDisplayCell. Maybe there is a reason for that, but I don't see it. But there's more... In the willDisplayCell method, I resize the text field and both labels, bring the text field to the front, and even send the detail text label to the back. I know that all that is done correctly, because on exit from -tableView: willDisplayCell: forRowAtIndexPath: the cell's content view's subviews array is: cell.contentView.subviews on exit from willDisplayCell: ( UILabel: 0xd36770; frame = (11 24; 135 18); text = 'Detail Label Detail Label...'; clipsToBounds = YES; userInteractionEnabled = NO; layer = CALayer: 0xd36160, UILabel: 0xd35de0; frame = (11 2; 135 22); text = 'Text Label Text Label Tex...'; clipsToBounds = YES; userInteractionEnabled = NO; layer = CALayer: 0xd360b0, UITextField: 0xd30220; frame = (155 10; 135 23); text = 'Text Field Text Field Tex...'; clipsToBounds = YES; opaque = NO; autoresize = LM; tag = 1; layer = CALayer: 0xd30680 ) Note how all the frame rectangles are correctly set and note also that the text field is above both labels, in the subview order. Yet, the cell displays as in the picture: both labels have the correct size but display as if they extended across the entire content view. Moreover, the detail text label refuses to be displayed in the back, even though it *is* in the back by the time the willDisplayCell method exits. Given how common something like this must be (reusing standard cells, with frame changes) and how fundamentally important the view hierarchy is, I'm inclined to think that the behavior I'm seeing isn't a bug but, rather, the result of something trivial that I'm missing. Yet, I can't see anything wrong with my code, so I'd appreciate if someone looked at the sample project I created, which can be downloaded from http://www.restlessbrain.com/cocoadev/UITableView_cell_display_bug.zip To summarize, there are 3 strange behaviors that I'm seeing: a. the subview order for the subviews of the cell's content view changes between exiting -tableView: cellForRowAtIndexPath: and entering -tableView: willDisplayCell: forRowAtIndexPath: b. the label frame rectangles are resized but the labels display as if the frames had not been changed. c. setting a specific subview order has no effect on how the labels are displayed. If I'm not missing anything obvious, I'll file a bug report.

It's only ridiculous if the information is indeed locally accessible. It really depends on why the OP wants the IP address in the first place, which we don't actually have any information about right now. It's unusual for an application to even need to know its own IP address, and others have already pointed out a variety of problems with the idea. It's entirely possible that the OP is mistaken about even needing this information. But, let's assume for the sake of discussion that he's not mistaken and that he really does need it. If you are connected behind a NAT router, proxy server, etc. and need to know what your _public_ Internet address is, sometimes the only way to do it is to ask someone else (e.g. you won't always have UPnP or similar protocols to rely on). There's a reason www.whatismyip.com and web sites like it exist. I'm not suggesting that exact web site is the best way to find out the IP address needed, but the idea isn't necessarily as ridiculous as one might think.

How to schedule an application
hi, I want to schedule my application on a specified time. When the application is not running , the application should open on the specified time and process the scheduled task . If the application is running , the scheduled task should be processed within the application [without opening in a new application]. I had tried using a plist file and launchd to do it, but it always opens in a new application. Is this can be done using applescript ? thank you in advance. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I need a milder application badge
I have cause to display something like an application badge on the docktile of my app, but the alarums-and-excursions feel of the standard bright red badge with zigzag edges is a bit too strident for what I have in mind. Can anyone point me at a scrap of code that would give me the functionality of NSDockTile:setShowsApplicationBadge: and NSDockTile:setBadgeLabel:, but would let me control the color and perhaps the shape of the badge? Or is there a different approach that I might consider? I don't need to change the badge color and shape at run-time; I would be perfectly happy to have them hard-coded into the source for whatever class or category I end up using.

Instead of launching your application directly, you need to have launchd launch a little process of some kind which will do what you want. Is this can be done using applescript ? Actually, that might work. An AppleScript such as tell application MyApp ...[do what I want]... end tell will not launch a new instance of MyApp if MyApp is already running. But your app has to be scriptable -- the do what I want part If so, the little process of some kind could be an AppleScript application bundle. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: [iPhone] UITableView cell display bugs ?
From what you've said below, you probably should be creating a custom cell type based on UITableViewCellStyleSubtitle and add the third label to your class. At least in NSTableView (I haven't yet played with the iPhone), a cell class determines what is drawn at a particular row/column location. Right now it sounds like you're fighting UITableView rather than working with it.

Re: [iPhone] get iPhone's IP address...
Please note that NSHost is NOT publicly supported API on iPhone.
Attempts to use it may result in unexpected behavior and broken

Open Recent menu - how to populate it?

There is no UI, related to file, where NSDocument could help significantly. At least I believe so. My problem is that Recent menu is empty, because in Cocoa (AFAIK) it is maintained automatically by NSDocumentController, which is absent in my app. So, my question is - how to create and update the Open Recent menu manually? Where to store its items? How to populate this submenu when my app is loaded? Or should I use NSDocumentController anyway?

Re: Open Recent menu - how to populate it?
You can just go ahead and invoke -noteNewRecentDocumentURL: on [NSDocumentController sharedDocumentController]. You don't have to worry about explicitly creating or managing an NSDocumentController, or do anything else that requires NSDocument. TextEdit in Tiger did this (before it was converted to NSDocument).

Getting a CoreAnimation layer frame, accounting for zPosition?
This might be a stupid question, but I've searched around and found no answers. I have a CoreAnimation layer with a zPosition 0. If its 3D transform is CATransform3DIdentity, how do I get its exact frame as it appears on the screen? I already tried -bounds, and -visibleRect, and -convertRect:toLayer: with the toLayer being the view's body layer, and they all ignored the zPosition and returned the frames they would use if their zPosition was 0.

Re: NSDateFormatter issue (bug maybe)?
When you're generating/parsing a date format that's supposed to be stable like this, you should control the locale/calendar used by the formatter instead of letting the user settings control it. For example, your data can be entirely off when the user's calendar is not Gregorian. Instead, you should specify the system locale, [NSLocale systemLocale], and the gregorian calendar, [[NSCalendar alloc] initWithCalendarIdentifier:@gregorian], explicitly.

Re: How to schedule an application
Take a look at an application I publish called Script Timer. It will do what you want. It has a wide variety of scheduling options: specified time of the day, week, month, or year, on a repeating interval, and when certain events occur such as the start or end of idle of your computer, as well as 6 other events. More details can be found at http://www.appsandmore.com. Scheduling an Applescript using iCal is another possibility, though less convenient in my (probably biased) opinion. As Jerry points out, unless your program automatically runs the desired task when it launches, that task will have to be Applescriptable. In that case you would schedule your script with Script Timer, iCal, or launchd.

Best approach for selective spell-checking...
I'm trying to figure out how to prevent spell checking in my NSTextView from being applied to certain ranges within the text document. For context, the situation I'm in is my application, MarsEdit, allows users to edit HTML source code in a regular NSTextView. In a nutshell, I want to spell-check the users plain-text content but avoid triggering spell-check false positives inside the HTML markup. I'm already colorizing the markup text, so it would be reasonably easy for me to do something in that colorizing pass that identifies the off-limits nature of the markup text. I could for instance easily maintain an array of ranges for a document that should not be spell- checked. The question is, how do I best limit the spell checker from applying itself to this text? So far I've been taking advantage of check as I type for both grammar and spelling. This seems like the most user- friendly way to support spell checking. Do I need to switch to a manual approach, using NSSpellChecker's checkSpellingOfString:startingAt: ? Would it be possible to use this manually in a manner that simulates check as I type? It would be nice if NSSpellChecker offered a delegate relationship, something like willMarkMispelledWordInRange: ... where I could choose to have it keep quiet instead.

Are you certain the delegate is actually set? Do other delegate methods get called? How did you set the delegate? How you determine the relevant object in your data model is up to you - you have row and column indexes, your controller has to convert that to some way of referencing the object.

I could for instance easily maintain an array of ranges for a document that should not be spell- checked. Maybe add the colorized words to a dynamic dictionary, which you then pass to the spell-checker. Since the markup words are in the dictionary, they won't be considered misspelled. -- GG ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Core Data, NSArraycontrollers and secondary to-many relationships.
Hey folks, I'm working on a little project: http://recon-mac.googlecode.com , a frontend for Nmap. My Core Data model looks like this: http://recon-mac.googlecode.com/files/recon_datamodel.png I'd like to use a NSTableview to display a list of unique ports in a selected session. As you can see, the relationship between Session is a tiered two-many relationship. I have NSArrayControllers bound to the MOC for Session, Host, and Port. The relationships are also configured correctly. ie. Other, simpler, view work great. I've spent a few days playing with NSArrayControllers, fiddling with Content Array, Content Set, Content Object settings; tried understanding @distinctUnionOfSets and @distinctUnionOfArrays; but I've hit a wall. So... how do I do it. I know the solution must be embarrassingly simple, but it's eluded me.

Re: NSPasteboard and data types
Dave, I've worked with UIPasteboard, which I'm assuming is similar. dataForType: will contain string data if it's a type such as UTF8 text. My own PasteboardItem class had just data (NSData) and type (NSString) properties, and it's worked fine for everything. Once you have the type and data, you can then write methods to convert to strings or whatnot.

What I'm wondering is this: do I need to have separate string and data properties in DDPasteboardItem? I see that I can grab stringForType: and dataForType: from the pasteboard, but what's the difference between them (other than one returning an NSString and the other an NSData)?

fileManager:shouldMoveItemAtPath:toPath is never called
Hi,
I'm having a problem with moving files using
moveItemAtPath:toPath:error from NSFileManager. The operation moves a
file as it should, but associated delegate method is not called
(fileManager:shouldMoveItemAtPath:toPath). If I switch from moving to
copying (that is when I use copyItemAtPath:toPath:error instead of
moveItemAtPath:toPath:error) the equivalent delegate works fine. I
made a sample source code to show what the problem is - I'm including
it below. When I compile it and run in XCode 3.1.3 (on OSX 10.5.7) it
just prints OK and not Test move so that the delegate is not
called. And the file is moved as it should be...
Have you seen this before?

CoreData could not fulfill a fault for...
Hi all,I have a strange problem with my app. I have an entity named Item and a one to one relationship with another Download entity. When I want to download an item... I create the entity download with some property related to size and status of the download. I use a download controller to show the current downloads. When I stop a download I remove the download entity from the managed object context and save everything. But after all this, the console shows me this log: *CoreData could not fulfill a fault for '0x1b1970 x-coredata://B6A18328-7952-4068-8491-27EE905B1D04/Download/p148'* * * I don't have any Download object right now. The only thing I display is the download.item.title property... when there are downloads. But now that I have stopped it shouldn't be called because the downloads controller has no download objects. I also setted delete rules in this way: Item has a cascade delete rule on Download relationship, Download instead has a nullify rule on the inverse to Item. What am I doing wrong? I noticed that if I remove the only binding (downloadsController.selection item.title on the collection view displaying the downloads) I have no warnings at all. Having said that, however my program runs fine even with these logs. But I need to know what could be wrong.

Well, if you're looking for -getBarcode: from NSImage, you're obviously out of luck. All you can do is scan the pixels, that's all that's in there, NSImage and NSImageRep do not interpret the content beyond pixels. However, you could do this by subclassing NSImageRep (or NSBitmapImageRep) and adding methods that do interpret barcodes at this level. You still have to do the work but this approach would give you a nice high-level interface to it.

NSTextView help
Hey everyone, I've got an interesting problem that I thought I could find the answer to, but have come up short so far. I'm building a master-detail interface, similar to Mail.app. I'm struggling with the detail view (displaying the currently selected item). In Mail, there are areas for the From:, Subject:, To:, etc, with a rich-text area underneath. This is what I'd like to recreate. I have it *kind of* working, but not how I'd like. I have some rich text of arbitrary length that I want to display along with the item's metadata (similar to Mail's From and Subject fields). However, I want all of these to be part of the same NSScrollView, so that when I scroll, both the metadata fields and the rich text content move. The problem I'm facing is that in order to display the RTF data properly, I need an NSTextView, but NSTextView has its own enclosing scroll view that's conflicting with my overall scrollview. In addition, I need to be able to dynamically resize the overall clipped view so that the scrollbars change appropriately. I might be able to use the WebView object to fake it, but that seems like a less-elegant solution. However, if it's the only one, I suppose I could go with that and then just use CSS to style everything. So, in a nutshell, how can I recreate the detail view as found in Mail.app?

Re: intelligent flexible popup
I seem to have fallen into the pitfall you described below. I can get the table view to display values in a combo box from a data source, which takes those values from an array in the model. I also have autocomplete working. But I can't seem to get the values I choose to stick (remain displayed) in the table. Since the tableview is reusing the combo box cell, I don't see how you specify a different value for each row (I only have one column). (The choice values do appear when you click the arrow, but selecting them does not store a value.) Also, I'm not clear on when you capture a selection to get the value transferred to the model. Are you supposed to use some notification to know that the field has been edited, and then capture that value and transfer it to the model. Sorry if this seems basic, but I've looked over the documentation and some sample code and just don't get it. Thanks .

In what way? Are you referring to the fact that a menu can represent an object, whereas a combo box is just a (possibly-pre-baked-chosen-from-the- menu) string? In both cases it's not the NSTableView but your custom data source that would make these decisions (ie, what that new object that was set really means in that context). I meant, if you used the NSComboBox methods that told you which item of the popup list was chosen (e.g. indexOfSelectedItem), you'd know what was chosen -- if something *was* chosen from the list -- as a selection index, but the table view would nevertheless set the underlying string as the value of the property bound to the column. Storing or using such combo box selection indexes is tricky to do with a table view, because they don't fit into the bindings *or* the data source patterns. Even knowing where you might usefully call these selected item methods is puzzling. So yes, if you understand that the value corresponding to the column is a string which *may* match (isEqualToString:, not ==) a list of strings you separately maintain, then there's no problem. The easy-to-fall-into pitfall is having the data model property be an index into an array of (say) state names, but returning the string name of the state in place of the index when supplying data to the table view. In that case, changing the string for one row changes that string everywhere it's used, which is usually not what's intended. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
