标题: ios - 捕获图像无法正常工作。？

您好，我是开发 iOS 应用程序的新手，请帮助我。我在使用 UIImagePicker 捕获图像时遇到问题。我已将 hip mob 应用程序集成到我们的应用程序中。

在该窗口中，我想显示一个 UIButton 以便用户单击该 UIButton 应捕获图像。当我单击按钮时，它会抛出一条消息(其 View 不在窗口层次结构中!)。

我认为这是由于这个聊天窗口造成的。这是我的代码片段。!

[[HMService sharedService] openChat:self withSetup:^(HMChatViewController * controller)
{
 controller.chatDelegate = self;
 controller.chatView.receivedMessageFont = [UIFont systemFontOfSize:20.0];
 controller.navigationBarHidden = YES;
 UIView * viewObjForVehicleDetails = [[UIView alloc]init];
 UIButton * btnForCaputrePhoto = [[UIButton alloc]init];
 [btnForCaputrePhoto addTarget:self actionselector(CapturePhotoImage) forControlEvents:UIControlEventTouchUpInside];
  btnForCaputrePhoto.frame = CGRectMake(55, 90, 103, 85);
 [controller.chatView addSubview:viewObjForVehicleDetails];
 [viewObjForVehicleDetails addSubview:btnForCaputrePhoto];
 [[controller.chatView table] registerClass:[ChatTableViewCell class] forCellReuseIdentifier"ReuseChatTableViewCell"]; 
} 


 -(void)CapturePhotoImage
{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:picker animated:NO completion:nil];

}   


- (void)imagePickerControllerUIImagePickerController *)picker didFinishPickingMediaWithInfoNSDictionary *)info
{
[picker dismissViewControllerAnimated:YES completion:NULL];
}

提前致谢!

Best Answer-推荐答案

首先确保您在 View Controller 中使用了以下委托(delegate)

<UINavigationControllerDelegate, UIImagePickerControllerDelegate>

第二次使用这一行来显示 ImagePicker:-

[self presentModalViewController:picker animated:YES];

替代方式:-

[self.view addSubview:imagePicker.cameraOverlayView]
