Custom “Use”, “Cancel”,“Retake” and “Reverse Camera” button event using UIImagePickerController

问题

I am making a custom photo picker. so i have used

imagePickerController.showsCameraControls = NO;

And i have created one camera overlay view and use

imagePickerController.cameraOverlayView = overlayView;

So, I need to implement custom button option, Can anyone please tell me how can i give customize button event using UIImagePickerController?

Thanks in advance.

You can build a UIViewController, take it's view as the image picker's overlayView. All your custom buttons are controlled by this UIViewController.

e.g.

UIButton *myBtn = [[UIButton alloc] initWithFrame:btnFrame];

[myBtn addTarget:self action:@selector(myBtnPressed) forControlEvents:UIControlEventTouchUpInside];

[overlayView addSubview:myBtn];
