When I was setting UITableView tableHeaderView using beginUpdates&endUpdates，every day there will be dozens of crash in line 259
code:
[self.tableView beginUpdates];
self.tableView.tableHeaderView=self.topView;
[self.tableView endUpdates]; // line 259 crash
Below is the crash information：

Just remove [self.tableView beginUpdates];and[self.tableView endUpdates];
how are you setting the constraints on self.topView ? Looking at the stacktrace, it seems like the system cannot satisfy all the constraints. I would look at topView and make sure that all the constraints are valid.

We are having a crash in Foundation, but we are unable to detect what could be the problem. We think that maybe an animation could trigger this problem.
Has anybody encounter this kind of crash? Here is the trace of the problem.

I have an issue where a screen with autolayout that works great on iOS 8 - but crashes on iOS 7.
All subviews are configured in the XIB.
The error message is:
Terminating app due to uncaught exception 'NSGenericException', reason: 'Unable to install constraint on view.
Does the constraint reference something from outside the subtree of the view? That's illegal.
constraint:<NSLayoutConstraint:0x7ef80720 V:[UIImageView:0x7ef7fb40]-(0)-[UILabel:0x7ef802f0]> view:<UIView: 0x7ef7f1e0; frame = (0 0; 768 275); autoresize = RM+BM; layer = <CALayer: 0x7ef7f240>>'

What is the issue?
Turns out these two lines caused the crash:
self.ninjaStarImage.layer.removeFromSuperlayer()
self.view.layer.addSublayer(self.ninjaStarImage.layer)
Moving them to viewDidLayoutSubviews solved the problem
I have a crash that happens only in IOS 7, I cannot reproduce it but it happens a lot. Does some one have an answer or at least have any idea where the problem can be.
I've allready removed all the warnings regarding ios7 and the crash still occurs.
Log is attached.

I get the same issue. The strange thing is it only occurs in 3.5inch devices (ip4, ip4S), os7.x. works fine on ip5.
UPDATE: our team found the root cause. It's because we use this animation in code.
[UIView animateWithDuration:0.4f delay:0 usingSpringWithDamping:0.5f initialSpringVelocity:0.3f options:UIViewAnimationOptionCurveEaseOut animations:^{
self.transform = CGAffineTransformMakeScale(sx,sy);
} completion:^(BOOL finished) {
self.hidden = !visible;
}];
to fix the bug, we avoid to run the animation if iOS <8.0
if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_7_1) {
[UIView animateWithDuration:0.4f delay:0 usingSpringWithDamping:0.5f initialSpringVelocity:0.3f options:UIViewAnimationOptionCurveEaseOut animations:^{
self.transform = CGAffineTransformMakeScale(sx,sy);
} completion:^(BOOL finished) {
if (finished) {
self.hidden = !visible;
}
}];
} else {
self.transform = CGAffineTransformMakeScale(sx,sy);
self.hidden = !visible;
}
Hope this help!
Thanks for who ever responded.
I solved it by removing the keyboard (resignFirstResponder) before poping the view controller.
In that screen I had 2 textfields that one of them was connected to the keyboard(inpuAccessoryView)and the other just activated the first one (I was developing a chat), when poping the view controller something probably went wrong.
Hope this will help someone.
I had a similar crash, except it happened when I did removeFromSuperview on a UIView that was created while inside a network callback. [NSISEngine withBehaviors:performModifications:] was where it started to go wrong after removeFromSuperview
eg. inside handleReadStreamEvent
if (!CFReadStreamSetClient( inputStream, kCFStreamEventHasBytesAvailable | kCFStreamEventErrorOccurred | kCFStreamEventEndEncountered | kCFStreamEventOpenCompleted
, handleReadStreamEvent, &context ) )
It seems any view that was created while inside this callback, crashed when it was removed from the superview - most of the time.
I ended up using this whenever I was making any UIView changes when inside the callback.
- (void)performSelector:(SEL)aSelector withObject:(id)anArgument afterDelay:(NSTimeInterval)delay;
The same happened when inside a looptimer callback
CFRunLoopAddTimer( CFRunLoopGetMain(), timeoutTimer, kCFRunLoopCommonModes);
I get the next line on the crash log:
[NSConcreteMapTable assign:key:value:isNew:]
This crash happens on iOS 7, but not on iOS 8.
Somewhere before this line there are calls for NSLayoutConstraint:
-[NSLayoutConstraint _addLoweredExpression:toEngine:integralizationAdjustment:lastLoweredConstantWasRounded:mutuallyExclusiveConstraints:]
-[NSLayoutConstraint _addToEngine:integralizationAdjustment:mutuallyExclusiveConstraints:]
-[NSLayoutConstraint _addToEngine:]
Do you guys think this crash has something to do with the Storyboard layout constraint I have set?

seems like your using iOS 8 only constraints go to the storyboard open it on the top left corner you will see a little yellow icon with reading mark on it press on it and search for iOS8 only warnings, if you find any remove those constraints and rebuild your application.

Maybe for someone this will look familiar and he could help to understand root of problem.
I got the same crash log.And my reason is the view controller is released but the UITextField.delegate is not setting nil. So you can set UITextField.delegate = nil in dealloc of the view controller.
