[英]Calling method presentViewController from the UIViewController in an asynchronous way
是否有任何機制以異步方式調用presentViewController方法？
UIImagePickerController *imagePicker = [[UIImagePickerController alloc]init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.mediaTypes = @[(NSString *) kUTTypeImage];
imagePicker.allowsEditing = NO;
[self.viewController presentViewController:imagePicker animated:YES completion:nil];
不，這是設計使之同步的。 但是您可以啟動另一個線程，然后在該線程中執行同步調用。 但是我不會那樣做。
UI方法必須在主線程上運行，因此無法以異步方式調用它
是否UIViewController調用方法presentViewController從內存中刪除？
