帮帮我,我遇到麻烦了,SO 不接受这类问题。请展示您迄今为止所做的尝试,以使人们对您的问题感兴趣。 你好。我只想在 iphone 相机上添加按钮 【参考方案1】:您需要创建一个 CustomOverlayView。然后像这样配置你的选择器:
overlay = [[CustomOverlayView alloc]initWithFrame:self.view.bounds];
overlay.delegate = self;
picker = [[UIImagePickerController alloc]init];
picker.delegate = self;
picker.navigationBarHidden = YES;
picker.toolbarHidden = YES;
picker.wantsFullScreenLayout = YES;
picker.allowsEditing = YES;
if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera])
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
else
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
picker.showsCameraControls = NO;
picker.cameraOverlayView = overlay;
【讨论】:
【参考方案2】:这将起作用:
- (void)showImagePicker:(UIImagePickerControllerSourceType)source
UIImagePickerController *imgPicker = [[UIImagePickerController alloc] init];
imgPicker.sourceType = source;
imgPicker.delegate = self;
[self presentModalViewController:ipc animated:YES];
按钮按下动作:
- (IBAction)chooseImage:(id)sender
[self showImagePicker:UIImagePickerControllerSourceTypePhotoLibrary];
然后这样做:
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
[picker dismissViewControllerAnimated:YES completion:nil];
或通过正确的操作执行此代码
