我在相机上使用自定义叠加框架.在导航栏上,我在中间有app图标,左边有一个后退按钮.
所以我想删除捕获按钮旁边的默认取消按钮,但我不想删除相机单击按钮.我做过研究,但我找不到完美的答案.我已经使用了以下代码,但它也删除了单击按钮.
[picker setShowsCameraControls:YES];
解决方法
我觉得你应该为你的uiimagepickercontroller添加自定义CameraOverlayView并隐藏CameraControls.This不会显示你的取消按钮.
picker = [[UIImagePickerController alloc] init]; picker.delegate = self; picker.sourceType = UIImagePickerControllerSourceTypeCamera; [picker setShowsCameraControls:NO]; CGRect screenBounds= [UIScreen mainScreen].bounds ; UIView *overlayView = [[UIView alloc] initWithFrame:screenBounds]; [overlayView setAutoresizesSubviews:YES]; [overlayView setAutoresizingMask:UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleBottomMargin|UIViewAutoresizingFlexibleTopMargin|UIViewAutoresizingFlexibleLeftMargin|UIViewAutoresizingFlexibleRightMargin]; UIButton *captureButton=[[UIButton alloc]initWithFrame:CGRectMake(screenBounds.size.width/2-30,screenBounds.size.height-60,60,60)]; [captureButton addTarget:self action:@selector(captureImage:) forControlEvents:UIControlEventTouchUpInside]; [captureButton setBackgroundImage:[UIImage imageNamed:@"icon"] forState:UIControlStateNormal]; [overlayView addSubview:captureButton]; [picker setCameraOverlayView:overlayView]; [picker setCameraDevice:UIImagePickerControllerCameraDeviceRear]; [self presentViewController:picker animated:YES completion:NULL];
这是Capture按钮的动作.
-(void)captureImage:(UIButton*)sender
{
[picker takePicture];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
[picker dismissViewControllerAnimated:YES completion:nil];
}
