ios – 创建未知类型的图像格式是一个错误Objective-C Xcode 8

Creating an image format with an unkNown type is an error

.

对于以前的版本是可以的.

这是我的代码：

UIImagePickerController* imgPicker=[[UIImagePickerController alloc] init];
imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imgPicker.delegate = self;
[self presentViewController:imgPicker animated:YES completion:nil];

并且代理回收图像的方法是..

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediawithInfo:(NSDictionary *)info {
       [picker dismissViewControllerAnimated:YES completion:NULL];
       UIImage *myImage = [info objectForKey:UIImagePickerControllerOriginalImage];
}

我也试过其他委托函数..

-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediawithInfo:(NSDictionary<Nsstring *,id> *)info{
}

但错误不行.

我不确定是Xcode 8的错误吗？如果有人面对这个问题并解决,请帮忙解决.
