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];}

并使用此委托方法获取图像.

-(voID)imagePickerController:(UIImagePickerController *)picker dIDFinishPickingMediawithInfo:(NSDictionary *)info{    [picker dismissVIEwControllerAnimated:YES completion:nil];}
