I have created a phone gap app having two select boxes for date control and time control. On tapping more than once on any of these select boxes causes the app to crash. It gives the following error:
Error 1.** WebKit discarded an uncaught exception in the webView:willRemoveScrollingLayer:withContentsLayer:forNode: delegate: -[WebActionDisablingCALayerDelegate setBeingRemoved:]: unrecognized selector sent to instance 0x78f35320
Error 2. Terminating app due to uncaught exception 'NSGenericException', reason: 'UIPopoverPresentationController () should have a non-nil sourceView or barButtonItem set before the presentation occurs.
I have read an answer (UIActivityViewController crashing on iOS8 iPads) to solve this by native approach. Can anyone let me know how to fix it in the hybrid app.
Thanks
in my case (phonegap app with OnsenUI Framework) I faced the same problem and I figured out it happens due to -webkit-overflow-scrolling: touch; on multiple elements inside a wrapper. After removing the error was gone (at least in my case)

I have a three textfields Email ID, Mobile Number, Name in webview. When I enter an invalid email id and move to mobile number textfield a validation popup is displayed "Please Enter Email ID". However, when double tapping the mobile number textfield the app crashes and I get the below crash report.
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Application tried to present modally a view controller <WebValidationBubbleViewController: 0x131ddf7e0> that is already being presented by <Mx_ScreenController: 0x1330a4800>.'
Please help me to resolve it
There are some UISwitches at page (xamarin forms)
After keyboard opening there is a crash related to haptic feedback:
Terminating app due to an uncaught exception 'NSInternalInconsistencyException', reason: 'Exception raised while auto-deactivating for style 2: force deactivating with style TurnOn which is not active
It looks like iOS issue, and I have not found any workarounds.
There is a scenario, when I try to take a picture on a device and I press the "shutter" button and right after that I press cancel (dismiss) – as a result, I get error that I can't track. It says:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** setObjectForKey: object cannot be nil (key: UIImagePickerControllerOriginalImage)'
*** First throw call stack:
(0x18271c2d8 0x193f400e4 0x182605428 0x18df304e8 0x18df30188 0x18df7d728 0x18df7dd28 0x188ef111c 0x188ef08a4 0x100f80fd4 0x100f80f94 0x100f85c28 0x1826d37f8 0x1826d18a0 0x1825fd2d4 0x18be136fc 0x1871c2fac 0x1002c35c0 0x1945bea08)
More information about the context:
I have iPhone 6 running iOS 8.3
I'm using the UIImagePickerController it crashes before calling the "imagePickerController: didFinishPickingMediaWithInfo:" method.
I have custom overlay with cancel button, which calls method to dismiss the UIImagePickerController.
Is this a common bug of the iOS or do I have something wrong?
Could it be because I use custom overlay with the custom cancel button?
Having a strange problem that is getting me into a bit of a panic. Just tested my app on iOS7, when I try to present one of my view controller via segue. I get the error message:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '`**Application tried to present a nil modal view controller on target <SendMessageViewController: 0x15524320>.'**`
Have no idea why this is happening. It works fine in iOS8 but could someone give me some pointers to what I might be doing wrong please?
First of all check the identifier of the viewcontroller is same that you mentioned in storyboard.
Than set back point on this exception to see if model is not nill.
UIAlertController is not supported by iOS 7 so in you're situation you should check the version of the iOS device and that use particular logic.
Use condition to detect if it is possible to use UIAlertController
if NSClassFromString("UIAlertController") != nil {
// Use it
} else {
// Fall back
}
I have multiple UITableviewControllers which support landscape mode and one UIViewController which does not support landscape mode. Regardless of which view is showing, when I close the app while in landscape mode I get the following exception:
* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[LedgerViewController setRefreshed:]: unrecognized selector sent to instance 0x161df0'
Closing the app in portrait mode does not generate the exception.
A full search of my project does not find the term "setRefreshed" nor can I find the term in any Apple documentation or via Google.
Any ideas?
I found the problem thanks to the AWESOME people at raywenderlich.com who take the time to write some of the best tutorials available: My App Crashed, Now What? – Part 1
An exception breakpoint led me to some poor code in my ApplicationDelegate which assumed the navingationController's rootViewController was "RootViewController" which has a BOOL property of "refreshed". That was a good assumption until I implemented a different view for landscape mode. Hence the reason why the exception was only thrown in landscape mode.
Things I learned today:
With KVC, it should have been obvious to me that "setRefreshed" is the KVC equivalent to "????.refreshed".
I should have read up on advanced debugging techniques years ago.
