隱藏UIImagePickerController中的記錄按鈕

Question

我對UIImagePickerController有疑問。我可以使用UIImagePickerController作爲預覽嗎？如果我這樣做，我必須隱藏記錄按鈕，有沒有辦法做到這一點？或任何其他方法來顯示除UIImagePickerController以外的預覽。

感謝您的幫助...

您可以通過使用隱藏UIImagePickerController的控制：在圖像內看看這個代碼，它會隱藏所有的控件：

[myImagePickerController setShowsCameraControls:NO]; 

編輯選擇器允許您創建和添加自己的自定義控件。不幸的是，你不能有選擇地隱藏選擇器內的控件，所以這是另一種選擇。

- (void)showCamera 
{ 
    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) 
    { 

     myImagePicker = [[UIImagePickerController alloc] init]; 

     [myImagePicker setSourceType:UIImagePickerControllerSourceTypeCamera]; 
     [myImagePicker setDelegate:self]; 
     [myImagePicker setShowsCameraControls:NO]; 
     UIView *overlayView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; 
     UIButton *switchCameraButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 
     [switchCameraButton setFrame:CGRectMake(10, 430, 72, 40)]; 
     [switchCameraButton addTarget:self action:@selector(changeCamera:) forControlEvents:UIControlEventTouchUpInside]; 
     [overlayView addSubview:switchCameraButton]; 
     [myImagePicker setCameraOverlayView:overlayView]; 
     [self presentViewController:myImagePicker animated:YES completion:nil]; 

    } 
} 
- (IBAction)changeCamera:(id)sender 
{ 
    if (myImagePicker.cameraDevice == UIImagePickerControllerCameraDeviceFront) { 
     [myImagePicker setCameraDevice:UIImagePickerControllerCameraDeviceRear]; 
    }else{ 
     [myImagePicker setCameraDevice:UIImagePickerControllerCameraDeviceFront]; 
    } 
}
