objective-c - iOS 7.1 UIImagePickController 開啟相機 Snapshotting a view
在IOS 7.1中使用imagepickcontroller 開啟相機的時候執行
1 2 3 4 5 6 7 8 9 | <code> self.picker.delegate = self;
self.picker.sourceType = UIImagePickerControllerSourceTypeCamera;
self.picker.showsCameraControls = YES;
self.picker.modalPresentationStyle = UIModalPresentationOverCurrentContext;
self.picker.cameraViewTransform = CGAffineTransformMakeScale(1, 1);
[Controller presentViewController:_picker animated:YES completion:nil];
presentViewController命令中在输出这段命令是怎么回事，看的烦死了。网上的办法试过了，延迟执行。没用啊

Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates.
