performSelector: withObject: afterDelay help for noob please
Hi There, I have been scratching my head and trying everything to get this to work and as a noob I find the docs a bit sparse of real world examples. I am trying to get performSelector: withObject: afterDelay to work but not sure what to stick where. I have a bit of static text I set with a value of: @record Added with the following: [complete setStringValue:@Record added]; and I want it to disappear after 3 seconds and I thought the easiest way would be to just change the value to: @ with a timer. Currently I have this: [self setStringValue:complete withObject:@ afterDelay:3.0]; Which doesn't seem to work and has the following warning: 'mainController' may not respond to '-setStringValue:withObject:afterDelay:' What am I doing wrong please and what should my code really be?

Trying to display a static image on my window. Any tips would be great
Hi All, I have been trying to get a static image to display in a corner of my window and it has to literally just sit there and do nothing however I have searched and searched Apple's dodumentation but no success yet. I have dropped an Image View onto the window in IB and set the following in my .h file in Xcode: IBOutlet NSImageView *theImage; Then in my .m file I have this so far: NSString *imageName; NSImage *tempImage; imageName = [[NSBundle mainBundle] pathForResource:@logo ofType:@PNG]; tempImage = [[NSImage alloc] initWithContentsOfFile:imageName]; My image is set in my project in the resources folder and is called logo.png and I hooked up the object to the NSImageView using IB. Can't seem to get it to display. I believe I have a line of code missing that will tie my MSImage to my NSImageView but not sure how. Any Ideas please? I'm pretty new to cocoa and don't understand all the lingo yet so be gentle please.

Core animation
Hi All, I was wondering if many of you have had a go at core animation yet? I am personally looking at making a piece of text fade in and fade out as a confirmation that something worked in my latest project. Currently I am just popping a bit of text on screen using: [succcessFlag setStringValue:@Record Added]; I presume we are talking pretty simple here but the question is how simple. If any of you knows of any cool tutorials on really quick and simple core animation text effects could you please give me the heads up. I've Googled loads for this but no joy yet.

Re: NSTextView to replace NSTextList confused
Hi Kyle and thanks for responding. I am not sure what part of the documentation you refer to when you say cocoa text system but I started reading about NSTextView and NSText and to be honest until I get more familiar with cocoa and everything clicks into place the documentation seems very confusing and tends to assume previous programming knowledge and a good understanding of the nuances of this sort of code. I have dabbled with other languages but the only language I managed to get a good understanding of was PHP. Cocoa seems a lot more disciplined in it's structure to me than PHP which is very forgiving indeed. So at the moment people have been kindly telling me what to do to achieve each little bit of my project that I don't understand and I have been figuring out bits myself along the way. this method seems to work best for me as I have started to figure out more and more without help. So I think I understand what you mean about not using NSString with an NSTextView but if you fancy throwing together a couple of lines of code so I can see visually how it's done then I think I will have a better chance of understanding it eventually. If you don't have time to then I understand totally. I am sure newbies like me can be a little demanding at times :-) Thanks Paul 2008/6/29 Kyle Sluder [EMAIL PROTECTED]: On Sat, Jun 28, 2008 at 8:28 PM, Papa-Raboon [EMAIL PROTECTED] wrote: So I did this and changed the header file for my mainController to take the NSTextView into consideration by changing: IBOutlet NSTextField* theNotes; to: IBOutlet NSTextView *theNotes; I then built and ran the project and surprise surprise it didn't work.

Any ideas what I am doing wrong please anyone. Look at the documentation for NSTextView. Notice how it doesn't implement -stringValue? Neither do any of its superclasses. Therefore you can't send an NSTextView a -stringValue message and expect anything meaningful. NSTextView does inherit from NSText, though, which responds to -string by returning the backing store. Do read the documentation for the Cocoa Text System. NSTextView is different from (and far more powerful than) NSTextField. --Kyle Sluder ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: NSTextView to replace NSTextList confused
This is great, I changed the line that said: myNotes = [theNotes stringValue]; to: myNotes = [theNotes string]; And it worked. I am not sure where abouts in the class reference for NSTextView it states that you should pass it a -string rather than a -stringValue but it worked all the same. Brilliant Thanks again Paul 2008/6/29 Nathan Kinsinger [EMAIL PROTECTED]: On Jun 29, 2008, at 1:58 PM, Papa-Raboon wrote: Hi Kyle and thanks for responding.

You should probably read most of it, but especially read the Building a Text Editor in 15 Minutes chapter which has sample code that should do what you need or at least get you in the right direction. If you are just learning Cocoa then you should really start with the Cocoa Fundamentals Guide: http://developer.apple.com/documentation/Cocoa/Conceptual/CocoaFundamentals/Introduction/chapter_1_section_1.html or a Cocoa programming book. --Nathan ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Newbie Confused by ABMutableMultiValue and how to store emails and phone numbers using them.
Hi again Cocoa geniuses,I am trying to get my head around the basics of the AddressBook framework. It seems there are not many examples of how to set/store email addresses and phone numbers in the addressbook. I understand I need to use ABMutableMultiValue to set my phone numbers and email addresses as I do the actual fields of the addresses (home or work) but I can't seem to figure out how it's done for either email addresses or phone numbers. I have this to set the home address: homeAddr = [NSMutableDictionary dictionary]; [homeAddr setValue:myStreet forKey:kABAddressStreetKey]; [homeAddr setValue:myCity forKey:kABAddressCityKey]; [homeAddr setValue:myCounty forKey:kABAddressStateKey]; [homeAddr setValue:myPostcode forKey:kABAddressZIPKey]; multivalue = [[ABMutableMultiValue alloc] init]; [multivalue addValue:homeAddr withLabel:kABAddressHomeLabel]; [person setValue:multivalue forProperty:kABAddressProperty]; [multivalue release]; This all seems to work beautifully but I can't for the life of me figure out how to do the same for the email addresses and telephone numbers. If anyone knows how to do this would it be possible to get the heads up from someone please as it's driving e nuts. As a complete newbie to Cocoa, MVC and OOP I understand examples better than verbose descriptions and that's where Apple's documentation seems a little sparse :-) Cheers Paul Randall ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

NSTextView to replace NSTextList confused
Hi there guys. I am a newbie to OOP and cocoa and as a personal project I have been building a simple little app to allow me to quickly add people to the Apple address book and at the moment it works well using NSTextFields for every field, however I want to use an NSTextView to enter the text for the 'note' field for the new contact as it would be a lot better suited so I thought I could just lob an NSTextView at my window in Interface builder, wire it up to my mainController class like I did the text fields and change the reference in the header file to take the text view into consideration. So I did this and changed the header file for my mainController to take the NSTextView into consideration by changing: IBOutlet NSTextField* theNotes; to: IBOutlet NSTextView *theNotes; I then built and ran the project and surprise surprise it didn't work. In Xcode I get the following: warning 'NSTextView' may not respond to '-stringValue' (Messages without a matching method signature will be assumed to return 'id' and accept '...' as arguments.).

Re: Issues with addressbook framework
Aha, fixed it. Basically if any of you get this same issue with loading a framework the way I got around it was to delete the framework and the #import line in my code. Save my file and then re-import the framework, save, re-add my #import Addressbook/Addressbook.h line and all my addressbook elements of my code sprung into life. Schwet Cheese Paul This Cocoa is great to learn once you stat to get the hang of it... 2008/6/26 Papa-Raboon [EMAIL PROTECTED]: Hi All, I am currently trying to work through a tutorial regarding creating a simple app that allows you to enter an address into Apple's Addressbook database. I added the addresbook framework just as the tutorial explained and saved my files and I can see AddressBook.framework there in the source file listings under other frameworks where the tutorial suggests I add it but whenever I type in anything that should reference this framework like ABMutableMultiValue etc it fails to auto complete and it's not recognised when I build. Has anyone else seen this issue before and how did you get around it?

Where can I get some examples of if() conditionals being used with string variables in Objective-C
Hi All,
Anybody know where can I get some examples of if() conditionals being used
with string variables in Objective-C?
To be specific, I am trying to use an if conditional to check the value of a
string being a certain value and then replacing it with a different value if
the condition returns TRUE.
Currently I have:
NSString *theName = [NSString stringWithFormat:@%@ %@, [firstName
stringValue], [lastName stringValue]];
I thought that this would work but it doesn't:
if ([NSString theName] == @John Lenon) {
// then something here using setStringValue but haven't got a clue how to do
this.
}
I want to check if theName is currently John Lenon and change it to be
Ringo Starr.
Any help would be greatly appreciated thanks as I am a complete newbie and
need to get my head around many things in Objective-C.
Thanks
Paul Randall

Giving focus to a specific text field after pressing a button
Hi Guys. I was wondering it it is possible to pass cursor focus back to a specific NSText UI element after pressing a button. I have been looking at NSControl and NSText field but can't seem to find a solution to this one.

Auto pop-up list from State field in Address book database
Hi Guru dudes,I am working on a simple application where I want to get a list from a file out of a file. Maybe XML or a flat text file and I want the list to pop up and drill down based on what I type so that I can select them. Like many web sites do using AJAX technologies. Can anyone tell me where to look for the equivalent in Cocoa please? I am a newbie so please be gentle with the terminology.

Newbie pulling my hair out regarding a simple xcode issue. Please help :-)
Hi All, I have been trying to get my hair around Cocoa programming and have worked through many a tutorial and it seems to be coming to me slowly. I wondered if anyone could help me figure out a simple exercise that I came up with myself to make it clearer how to properly address objects with each other. I have a simple interface in interface builder that has two text fields (NSTextField) and a multi-line NSTextField and a button. The two text fields are firstName lastName. The multi-line text field is peoplesNames The push button is addName. All I need this to do is allow me to type a first name, last name, press a button and the name gets added to the multiline text field. Only issue is I cannot get my head around what connects to what in Interface Builder. I guess I need to concatenate the two name fields into a single NSMutableString (with a space in the middle) then add them to an NSMutableArray which is looped through to display in the multiline text field. This would be an insignificant task for an experienced Cocoa programmer but would teach newbies like me a thing or two. Many of the tutorials seem to be far too simple. And others too complicated. Where's the intermediate ones like this. Could anyone please help in some way either with a description of what needs to be done or a link to a similar tutorial.
