uiwebview webthread crashing - uiwebview
My App with an UIWebView is crashing a lot. The crash is often slightly different, but it's always a crash of the "WebThread" with a similar stack trace.
I found this question but I don't think it's my case, I have iOS 6 and I'm not loading Office documents.
I'm using websocket to send messages to a server and using ajax commet to receive messages from a server.
The crashes always happen when I'm starting that connections.

I fixed the bug, I was sending javascript logs to cocoa like this, I fixed those crashes by removing this.
Actually, that's not necessary anymore for iOS 6 cause now it's possible to debug javascript using MAC OX safari =)

Core Data, NSPredicate causes NSInvalidArgumentException
I am calling this code on a background thread.
backgroundContext.performAndWait {
let fetchRequest:NSFetchRequest<BlogPost> = BlogPost.fetchRequest()
fetchRequest.predicate = NSPredicate.init(format: "postid=%#", argumentArray: [someInt64Value]) // this line creates an exception
_ = try? fetchRequest.execute()
....
}
If I remove the predicate, it works fine. The same predicate works just fine if used inside a fetchResultController. postid is Int64 but if I changed the predicate to any other key it would give the same NSInvalidArgumentException
This is very similar to Core Data Error - NSDate localizedCaseInsensitiveCompare: unrecognised selector sent to instance

libc++abi.dylib: terminating with uncaught exception of type NSException
I found the issue. Passing an Int64 confuses the argumentArray, casting it to Int fixes the issue.
This seems to be a bug in NSPredicate() filed as radar 28749194
let id:Int64 = 5785905063264256 // Making this Int works
#objc class Test:NSObject {
let postid = id
}
let predicate = NSPredicate(format: "postid == %#"
, argumentArray: [id])
let mytest = Test()
predicate.evaluate(with: mytest) //false but should be true
Why would app try to save to PLSharedManagedObjectContext?
The following is a crash report I received from my crash reporting service, HockeyApp. The reason for the failure is a failure to save in PLSharedManagedObjectContext. I (think) I am doing all of my saves in the main app delegate managedObjectContext. Why is the PLSharedManagedObjectContext the one being saved to?
I think this is the relevant code:
-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
__ENTERING_METHOD__
DLog(#"info:%#",info);
NSURL *assetURL = [info objectForKey:UIImagePickerControllerReferenceURL];
__block UIImage *originalImage = [info objectForKey:UIImagePickerControllerOriginalImage];
CGSize cropSize = CGSizeMake(320,320);
CGFloat previewWindowHeight = 100.0f;
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
__block UIImage *previewImage;
if (originalImage) {
DLog(#"WE DO HAVE AN ORIGINAL IMAGE");
}
else {
DLog(#"WE DO NOT HAVE AN ORIGINAL IMAGE");
}
ImageEditor *imageEditor = [[ImageEditor alloc] initWithNibName:nil bundle:nil];
[imageEditor setRotateEnabled:NO];
[imageEditor setCheckBounds:NO];
[imageEditor setSourceImage:originalImage];
[imageEditor setPreviewHeight1:[NSNumber numberWithDouble:previewWindowHeight]];
[imageEditor setCropSize:cropSize];
imageEditor.doneCallback = ^(UIImage *editedImage, UIImage *originalImageMax1024, BOOL canceled){
picker.delegate = nil;
if(!canceled) {
if (editedImage) {
UIImage *scaledThumbnail = [HFImageEditorViewController getThumbnailForImage:editedImage size:CGSizeMake(PERSON_THUMBNAIL_SIZE,PERSON_THUMBNAIL_SIZE) round:PERSON_THUMBNAIL_ROUND];
[self setObjectCroppedImage:editedImage thumbnail:scaledThumbnail updateHeaderView:YES mocSave:NO];
[self setObjectMainImage:originalImageMax1024 mocSave:NO];
[Helper mocSave];
self.imageToShow = originalImage;
}
}
[Helper controller:self dismissControllerModal:YES];
};
[library assetForURL:assetURL resultBlock:^(ALAsset *asset) {
if (!originalImage) {
originalImage = [UIImage imageWithCGImage:[[asset defaultRepresentation] fullResolutionImage]];
}
[imageEditor setSourceImage:originalImage];
previewImage = [UIImage imageWithCGImage:[asset aspectRatioThumbnail]];
[imageEditor setPreviewImage:previewImage];
[imageEditor reset:NO];
//DLog(#"originalImage.imageOrientation:%d",originalImage.imageOrientation);
[picker pushViewController:imageEditor animated:YES];
} failureBlock:^(NSError *error) {
DLog(#"Failed to get asset from library");
if (originalImage) {
[imageEditor setSourceImage:originalImage];
[imageEditor setPreviewImage:nil];
[imageEditor reset:NO];
[picker pushViewController:imageEditor animated:YES];
}
else {
[Helper showSimpleAlertWithTitle:NSLocalizedString(#"Image Could Not Be Set", #"Image Could Not Be Set") message:NSLocalizedString(#"Failed to retrieve selected image asset from the Library.", #"Failed to retrieve selected image asset from the Library.")];

PLSharedManagedObjectContext appears to be an undocumented class that's part of PhotoLibraryServices.framework. That framework is itself undocumented, but the fact that it shows up in your backtrace implicates it. As a result I don't think that this exception has anything really to do with your Core Data code. PhotoLibraryServices is using Core Data internally somewhere, and failing to do so. This might mean that you're doing something wrong with your photo handling, or it might be a framework bug. Either way, looking at your own Core Data code will almost certainly miss the point. Having said that, there's also an indication that a performBlock call might have been involved somehow. Depending on what your mocSave method does, there might be a connection.

The problem is on your HomeViewController. You have a [__NSArrayM objectAtIndex:]: index 2 beyond bounds [0 .. 1] This means you are trying to access an index that doesn't exists, I think on line 246
A DialogViewController with RefreshRequested and EntryElement crash when text entered
A DialogViewController contains an EntryElement and RefreshRequested handler is set (see code below).
Run in the simulator, debug mode, type some quick random text (containing spaces) in the EntryElement. Crash will follow.
What I am doing wrong ?
I guess this is a bug in DialogViewController not retaining some images that is garbage collected.
Is there a switch to trace garbage collector and removed objects ?
the offending code :
[Register ("AppDelegate")]
public partial class AppDelegate : UIApplicationDelegate
{
// class-level declarations
UIWindow window;
UINavigationController navController;
DialogViewController dv ;
public override bool FinishedLaunching (UIApplication app, NSDictionary options)
{
// create a new window instance based on the screen size
window = new UIWindow (UIScreen.MainScreen.Bounds);
navController = new UINavigationController();
var root = new RootElement("Test") {
new Section("Quick type some text") {
new EntryElement("that contains spaces", string.Empty, string.Empty)
}
};
dv = new DialogViewController(root, true);
dv.RefreshRequested += HandleDvRefreshRequested; // comment this line fixes the bug
window.MakeKeyAndVisible ();
if (UIDevice.CurrentDevice.CheckSystemVersion (5, 0)) {
window.RootViewController = navController;
} else {
window.AddSubview (navController.View);
}
return true;
}
void HandleDvRefreshRequested (object sender, EventArgs e)
{
dv.ReloadComplete();
}
}

=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================
It's a case of Autocorrection strikes back, aka bug #325 (and quite a few duplicates) and it's not MonoTouch specific.
Something, deep down, the simulated iOS gets corrupted and shows up while it wants to draw it's little red line to show something is misspelled.
This will only happen in the simulator and only when an UITextField has auto-correction enabled. Turning it off like this:
new EntryElement("that contains spaces", string.Empty, string.Empty) {
AutocorrectionType = UITextAutocorrectionType.No
}
will solve the issue (and you can do it only for your simulator builds with a #define).
