Crashes on latest Xcode / iOS

[ChrisWoodard]

Just rebuilt my project with the latest Xcode (Version 6.3.1 (6D1002)) and when I call

[MTPopupWindow showWindowWithHTMLFile:@"http://www..."];

the app bombs out with the exception:

* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* +[NSLayoutConstraint constraintWithItem:attribute:relatedBy:toItem:attribute:multiplier:constant:]: A multiplier of 0 or a nil second item together with a location for the first attribute creates an illegal constraint of a location equal to a constant. Location attributes must be specified in pairs' *** First throw call stack: (0x22ce6fef 0x31234c8b 0x22ce6f35 0x23ae36cb 0x239a585b 0xa76b9 0xa60d5 0x908fb 0x2645256b 0x2650143b 0x263b6a91 0x2633138f 0x22cacfed 0x22caa6ab 0x22caaab3 0x22bf7201 0x22bf7013 0x2a4d6201 0x2639ba59 0x8bdf5 0x317c0aaf) libc++abi.dylib: terminating with uncaught exception of type NSException

Anyone got any suggestions, it's been fine up till now :-(

Thanks.

Hi Chris,

Did you ever find a solution for this? I'm getting the same error. I submitted an app on April 25 with no issues, but today, getting the exact issue you described. Any help would be great. Thank you!

Hi, I'm afraid I didn't resolve this problem, due to time constraints I just ended up using an alternative 3rd party library.

You cannot specify constraints on views that are not in the view hierarchy any more. This is an Auto Layout restriction.

Hi,

Here what I did for fixed it, I change the multiplier on topc to 0.1f (in my case I put 6.0f to make the bullet button inside of box) or greater and that will work.

NSLayoutConstraint* topc = [NSLayoutConstraint constraintWithItem: closeBtn attribute: NSLayoutAttributeTop relatedBy: NSLayoutRelationEqual toItem: v attribute: NSLayoutAttributeTop multiplier: 6.0f constant: closeBtnOffset];

Hope that will help you @ChrisWoodard :)
