小编use*_*489的帖子

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.allowsEditing = YES;
[self presentViewController:imagePicker animated:YES completion:nil];

此代码使ios7设备上的EXC_BAD_ACCESS崩溃.在iOS6上 - 一切正常,UIImagePickerControllerSourceTypePhotoLibrary工作正常.
