Re: Updated View Bounds After Orientation Change...
David,
In IB, I have a vertical UIStackView with an image view and a text view
(stacked in that order). I add the activity indicator programmatically:
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
// add activity indicator and start animation
if _useActivityIndicator == true {
// set constraints
_imageView.addSubview(_activityIndicator)
_activityIndicator.centerXAnchor.constraintEqualToAnchor(_imageView.centerXAnchor).active
= true
_activityIndicator.centerYAnchor.constraintEqualToAnchor(_imageView.centerYAnchor).active
= true
_activityIndicator.startAnimating()
}
}
I get this error:
2015-10-26 22:44:42.971 Historic Sites Navigator[247:13410] Unable to
simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't
want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't
understand, refer to the documentation for the UIView property
translatesAutoresizingMaskIntoConstraints)
(
"",
"",
"",
"",
"",
"",
"",
"",
""
)
Will attempt to recover by breaking constraint
Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch
this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed
in may also be helpful.
I do not understand how the error is occurring.

I tried your suggestion, but the program terminates. I get this in the console:

You need to ensure they have a hierarchy relationship before activating the
constraints – you probably didn’t add one as a subview of the other yet.

Devs,

image view and starting the animation for the AIV. But, in the process of
waiting for the image to load, if I rotate the image view, the AIV needs to be
re-centered. I added code to listen for the status bar orientation change
notification, and have a method to invoke upon the notification
(UIApplicationDidChangeStatusBarOrientationNotification). In that method, I
attempt to get the bounds of the image view and use that to re-center the AIV
within the image view. But, it seems that the value of the bounds of the image
view is not changing when the device orientation changes. Is there a “reliable"
way to get the updated bounds for a view after the device orientation has
changed? Code ->
Why do all this at all? Just add 2 constraints that tie the center of the
activity indicator to its superview and it will remain centered always.
[_activityIndicator.centerXAnchor
constraintEqualToAnchor:_imageView.centerXAnchor].active = YES;
[_activityIndicator.centerYAnchor
constraintEqualToAnchor:_imageView.centerYAnchor].active = YES;
(or equivalent if you need to support prior to iOS 9).
// start listening for orientation changes
NSNotificationCenter.defaultCenter().addObserver(self, selector:
"orientationDidChange:",
name: UIApplicationDidChangeStatusBarOrientationNotification,
object: nil)
…
func orientationDidChange(notification: NSNotification) {
// get image view bounds
let viewBounds = _imageView.bounds
// recenter the activity indicator
_activityIndicator.center = CGPointMake(CGRectGetMidX(viewBounds),
CGRectGetMidY(viewBounds))

Swift charting
[image: chart.gif] Hey all, I am looking for a bar chart system written in Swift with a feature I haven't seen yet. You can add value filters - say three of them. High, medium, low. And the bars go up and would change color at the boundary. Anyone know of anything? I just started here.

Smooth adjustScroll of NSScrollView
Hi I am developing an application that looks similar to the OS X's Calendar.app. One of the nice features it has is the "gravity effect" to the grid lines, when the user performs vertical scrolling - if you scroll the calendar so that half-row is clipped by the Clip View, it automatically scrolls further until the whole row fits into the view. Documentation says that we should implement the adjustScroll method of the document view, where, given a proposed NSRect, we can update it however we want. I did implement this method, and it works, but the problem is that now scrolling is not smooth at all - It just scrolls "line by line", as it does in Windows (as in I move two fingers on the trackpad - and get lines simply displayed one after the other). Is this the intended behavior? If it is, how did Apple developers make their Calendar "adjustScroll"-ed scrolling so smooth? Or is there anything wrong in my code i should be looking to fix?

There's lots of stuff that works perfectly in AS that you *cannot do* in SB because SB is crippled and broken *by design*. (I've long since stopped counting. Any AE bridge that pukes its guts out at mere sight of InDesign simply isn't fit for use.) Unfortunately, I have no experience scripting Outlook so cannot tell you offhand how - or even if - you can do it in SB. One thing I can say is that your AS code looks a bit odd and non-idiomatic itself (though that is often the case with Office apps as their Apple event interfaces are weird and cranky as hell): set myObjectID to the id of (object of myWindow) set myContent to the plain text content of message id myObjectID In a standard Apple Event Object Model, an `id` value is a unique identifier for a single object; thus, a by-id specifier, which is what `message id ...` is roughly analogous to a managed pointer. So I wouldn't normally expect to be able to take the id of a window object and use it as the id of a message object; but then, like I say, Office apps' AE interfaces aren't exactly standard. Oh, and realize SB is spectacularly bad at coping with the more "eccentric" scriptable apps, so it may not be possible to do the same thing in SB. If so, you won't be the first person who's had to fall back to AS for some things, or just abandon SB completely.

Re: Scripting Bridge Question
Ok, I hear what you are saying but I’ve almost got it working as it is and what I’m doing is not that difficult and I should be able to do it in the Scripting Bridge, the thing that is confusing me is that: set myObjectID to the id of (object of myWindow) set myContent to the plain text content of message id myObjectID what is "message id” in this case? In There is a definition of: @interface SXOutlook2011Object : SXOutlook2011Item - (NSInteger) id; // The unique ID of a record. @end Which shows the id as being an Integer but on SBElementArray, there is a method: - (ObjectType) objectWithID:(id)identifier; Which takes an object, not an integer, I think if I could get the correct ID for the message I could just call this method which would solve my problem. I’ve got a work-around that seems to work which is to get the Outgoing Message from the current messages array instead of via the Window. This does seem to work, but and I think it will be ok to use it, I’m just slightly worried that there may be a case where the message of the front window is not the same as the current message…..

Scripting Bridge Question.....
Hi,
I’m using the Scripting Bridge to Target MS Outlook. I’m trying to figure out
how to do the following AppleScript using the Scripting Bridge. Please see Full
Script below, I’ve got most of the code, but I can’t seem to figure out the
right Objective-C code for these two statements:
set myObjectID to the id of (object of myWindow)
set myContent to the plain text content of message id myObjectID
on run
tell application id "com.microsoft.Outlook"
activate
set myWindow to the front window
if class of myWindow is not draft window then
return "Error - Not Draft Window"
end if
set myObjectID to the id of (object of myWindow)
set myContent to the plain text content of message id myObjectID
return myContent
end tell
end run
I have the following Objective-C code:
-(BOOL) outlookGetDraftWindowForWindowIndex:(NSInteger) theWindowIndex
returnDraftWindow:(SXOutlook2011DraftWindow**) theDraftWindowPtr
returnMessage:(SXOutlook2011OutgoingMessage**) theOutgoingMessagePtr
{
SXOutlook2011Application* myOutlookApp;
SBElementArray* myOutgoingMessageArray;
SBElementArray* myDraftWindowsArray;
SXOutlook2011DraftWindow* myDraftWindow;
SXOutlook2011OutgoingMessage* myOutgoingMessage;
SXOutlook2011Object*myDraftObject;
NSInteger myDraftObjectID;
//**
//**Get the Outlook Application
//**
myOutlookApp = [self.pSingletonManager.pScriptingBridgeManager
getHandlerWithAppInternalID:kBundleIDOutlook];
if (myOutlookApp == nil)
return NO;
if (theDraftWindowPtr != NULL)
*theDraftWindowPtr = nil;
if (theOutgoingMessagePtr != NULL)
*theOutgoingMessagePtr = nil;
myOutgoingMessageArray = [myOutlookApp outgoingMessages];
myDraftWindowsArray = [myOutlookApp draftWindows];
if ([myDraftWindowsArray count] < theWindowIndex)
return NO;
myDraftWindow = [myDraftWindowsArray objectAtIndex:theWindowIndex];
if ([myDraftWindow exists] == NO)
return NO;
//**
//**Save the Window before Getting the Message
//**
[myDraftWindow saveIn:nil as:myDraftWindow.name];
myDraftObject = myDraftWindow.object;
if ([myDraftWindow exists] == NO)
return NO;
myDraftObjectID = myDraftObject.id;
myOutgoingMessage = [self findMessageWithID:myDraftObjectID
inArray:myOutgoingMessageArray];
if (theDraftWindowPtr != NULL)
*theDraftWindowPtr = myDraftWindow;
if (theOutgoingMessagePtr != NULL)
*theOutgoingMessagePtr = myOutgoingMessage;
return YES;
}
Which works but takes for ever because:
myOutgoingMessage = [self findMessageWithID:myDraftObjectID
inArray:myOutgoingMessageArray];
Does a sequential search of the Outgoing Message array, which is ok if there
are only a few messages but as soon as you get more than about 100 it takes way
too long.
Any ideas on this would be greatly appreciated.
All the Best
Dave
