取消按鈕顯示爲禁用,並且當圖片選擇器控制器首先出現不工作禁用,但我移動到下一個視圖中選擇一個專輯,取消按鈕變爲啓用並開始正常工作。取消按鈕顯示在IOS使用presentViewController時的UIImagePickerController 5
我應該怎麼做,以保持取消按鈕啓用,所有的工作時間?
imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary])
{
NSArray *sourceTypes = [UIImagePickerController availableMediaTypesForSourceType:imgPicker.sourceType];
imgPicker.mediaTypes = sourceTypes;
[self presentViewController:imgPicker animated:YES completion:Nil];
}
