Getting a Screen Capture of UIView

Some times you have to capture a portion of you iPhone application programmatically;
The quickest way is to pass the target view to following method and get its screenshot as an UIImage;

[sourcecode language=”objc”]
-(UIImage*)captureFullScreen:(UIView*) targetView{
UIGraphicsBeginImageContext(targetView.view.frame.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *fullScreenshot = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIImageWriteToSavedPhotosAlbum(fullScreenshot, nil, nil, nil);
return fullScreenshot;
}
[/sourcecode]

– To capture the whole screen, you don’t need to pass any parameter to this method; instead, use self.view.frame in the first line.

– To save the captured image into your device’s album, use  the following.

[sourcecode language=”objc”]

UIImageWriteToSavedPhotosAlbum(fullScreenshot, nil, nil, nil);

[/sourcecode]

HAPPY DEVELOPMENT;
