ios - 设置Image picker sourceType，只选择图片，不选择视频

Question

我希望用户能够使用相机但不能选择拍摄视频。目前，当用户启动相机时，照片和视频控件都会显示在 View 的左下角。下面是我的 launchCamera 和 imagePickerController 方法。

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

self.image = [info objectForKey:UIImagePickerControllerOriginalImage];
self.challengePic.image = self.image;
if (self.imagePicker.sourceType == UIImagePickerControllerSourceTypeCamera) {
    UIImageWriteToSavedPhotosAlbum(self.image, nil, nil, nil);
    self.challengePic.image = self.image;

    }

[self dismissViewControllerAnimated:YES completion:nil];
}


- (IBAction)launchCamera:(id)sender {
if (self.image == nil && [self.videoFilePath length] == 0) {
    self.imagePicker = [[UIImagePickerController alloc] init];
    self.imagePicker.delegate = self;
    self.imagePicker.allowsEditing = NO;

    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
        self.imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
    }
    else {
        self.imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    }
    self.imagePicker.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:self.imagePicker.sourceType];

    [self presentViewController:self.imagePicker animated:NO completion:nil];
}

}

- (IBAction)launchAlbum:(id)sender {
if (self.image == nil && [self.videoFilePath length] == 0) {
    self.imagePicker = [[UIImagePickerController alloc] init];
    self.imagePicker.delegate = self;
    self.imagePicker.allowsEditing = NO;

    self.imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

    self.imagePicker.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:self.imagePicker.sourceType];

    [self presentViewController:self.imagePicker animated:NO completion:nil];
}

}

有什么方法可以设置图像选择器的 sourceType 以便只选择图片而不选择视频？提前致谢!

不要包含这一行:

self.imagePicker.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:self.imagePicker.sourceType];

来自UIImagePickerController class Reference :

By default, this property is set to the single value kUTTypeImage, which designates the still camera interface when capturing media, and specifies that only still images should be displayed in the media picker when browsing saved media. To designate the movie capture interface, or to indicate that only movies should be displayed when browsing saved media, use the kUTTypeMovie identifier….
