以下是我从崩溃报告服务HockeyApp收到的崩溃报告。失败的原因是无法保存在PLSharedManagedObjectContext中。我（想）我正在主应用程序委托managedObjectContext中进行所有保存。为什么PLSharedManagedObjectContext是保存到的？
我认为这是相关的代码：
-(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.")];
[Helper controller:self dismissControllerModal:YES];
}
}];
}

编辑：我认为ImageEditor中的这段代码可能与它有关：
- (IBAction)doneAction:(id)sender
{
__ENTERING_METHOD__
self.view.userInteractionEnabled = NO;
[self startTransformHook];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
CGImageRef resultRef = [HFImageEditorViewController newTransformedImage:self.imageView.transform sourceImage:self.sourceImage.CGImage sourceSize:self.sourceImage.size sourceOrientation:self.sourceImage.imageOrientation outputWidth:self.outputWidth ? self.outputWidth : self.sourceImage.size.width cropSize:self.cropSize imageViewSize:self.imageView.bounds.size];
dispatch_async(dispatch_get_main_queue(), ^{
UIImage *transform = [UIImage imageWithCGImage:resultRef scale:1.0 orientation:UIImageOrientationUp];
CGImageRelease(resultRef);
UIImage *scaledThumbnail = [HFImageEditorViewController getThumbnailForImage:transform size:_thumbnailSize round:_thumbnailRound];
self.view.userInteractionEnabled = YES;
if(self.doneCallback) {
self.doneCallback(transform, _sourceImage, NO);
}
[self endTransformHook];
});
});
}
+ (UIImage*)getThumbnailForImage:(UIImage*)mySourceImage size:(CGSize)size round:(BOOL)round {
//TODO THIS SHOULD BE MOVED TO THE BACKGROUND
UIImage *scaledImage = [HFImageEditorViewController scaledImage:mySourceImage toSize:size withQuality:kCGInterpolationHigh];
if (round) {
CALayer *imageLayer = [CALayer layer];
imageLayer.frame = CGRectMake(0, 0, scaledImage.size.width, scaledImage.size.height);
imageLayer.contents = (id) scaledImage.CGImage;
imageLayer.masksToBounds = YES;
imageLayer.cornerRadius = scaledImage.size.width/2;
UIGraphicsBeginImageContext(scaledImage.size);
[imageLayer renderInContext:UIGraphicsGetCurrentContext()];
scaledImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
}
return scaledImage;
}
答案 0 :(得分：0)
PLSharedManagedObjectContext 出现成为PhotoLibraryServices.framework的未记录的类。该框架本身没有文档，但它在你的回溯中出现的事实暗示了它。
因此，我不认为此异常与您的Core Data代码有任何关系。 PhotoLibraryServices在某个地方内部使用Core Data，但未能这样做。这可能意味着您在处理照片时遇到了问题，或者可能是框架错误。无论哪种方式，查看您自己的核心数据代码几乎肯定会忽略这一点。
话虽如此，也有迹象表明可能以某种方式涉及performBlock电话。根据{{1}}方法的作用，可能是一个连接。
