我正在开发一个基于标签栏的简单应用程序。我正在尝试打开图像选择器，使用通用代码从库中选择一些图像，如下所示：
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeSavedPhotosAlbum]) {
picker.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage,nil];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
[[UINavigationBar appearance] setTintColor:[UIColor greenColor]];
[self.navigationController presentViewController:picker animated:YES completion:NULL];
但它的崩溃与非常奇怪的日志。

我想添加一个相同代码在其他项目中工作的东西。我尝试过不同的项目。
