禁用重新录制，播放和使用video画面UIImagePickerController

我只想要一个筛选器： 当使用UIImagePickerController它使用两个屏幕。

但我不想要这个：

这可能吗？

@Fahri是正确的AVFoundation更灵活，但如果你想坚持使用UIImagePickerController你可以做的是closures相机控制通过设置showsCameraControls属性为NO ，然后呈现自己的视图和自定义方法。

将您的代码更改为：

takeVideo

 - (IBAction)takeVideo:(UIButton *)sender { UIToolbar *toolBar=[[UIToolbar alloc] initWithFrame:CGRectMake(0, self.view.frame.size.height-54, self.view.frame.size.width, 55)]; toolBar.barStyle = UIBarStyleBlackOpaque; NSArray *items=[NSArray arrayWithObjects: [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(cancelVideo)], [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil], [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera target:self action:@selector(shootVideo)], [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil], [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil], nil]; [toolBar setItems:items]; // create the overlay view UIView *overlayView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height-44)]; overlayView.opaque=NO; overlayView.backgroundColor=[UIColor clearColor]; // parent view for our overlay UIView *cameraView=[[UIView alloc] initWithFrame:self.view.bounds]; [cameraView addSubview:overlayView]; [cameraView addSubview:toolBar]; picker = [[UIImagePickerController alloc] init]; if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] == NO){ NSLog(@"Camera not available"); return; } picker.sourceType = UIImagePickerControllerSourceTypeCamera; picker.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil]; picker.delegate = self; // hide the camera controls picker.showsCameraControls=NO; [picker setCameraOverlayView:cameraView]; [self presentViewController:picker animated:YES completion:nil]; } 

shootVideo

 -(void) shootVideo { [picker startVideoCapture]; } 

cancelVideo

 - (IBAction)cancelVideo { [self dismissViewControllerAnimated:YES completion:nil]; }

如果您在发布您的问题之前已经检查过UIImagePickerController的文档，那么您可以使用AVFoundation库来构build您自己的相机控制器，以及任何您想要的控件和屏幕。 祝你好运！
