ios – 从自定义相机中删除取消按钮

2020年02月04日作者：佚名

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];
}

并使用此委托方法获取图像.

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    [picker dismissViewControllerAnimated:YES completion:nil];
}
