pulling an UIImage from a UITextView or UILabel gives white image
- by user293139
Hello all,
I need to grab an UIImage from a UITextView or UILabel. I've got a method that will pull an image successfully from other types of views ( [UIViewController view], MKMapView, UIButtons) but I am just getting a white rect for my UITextView.
I've been banging my head against the wall for a while and suspect something really, really basic.
many thanks!
@interface TaskAccomplishmentViewController : UIViewController {
MKMapView *mapView;
UILabel *timeLeftText;
UITextView *challengeText;
UIButton *successButton;
-(void) setChallangeImageToImageFromChallenge {
// works
// [currChallenge setChallengeImage:[UIImageUtils grabImageFromView:mapView]];
// [currChallenge setChallengeImage:[UIImageUtils grabImageFromView:[self view]]];
// [currChallenge setChallengeImage:[UIImageUtils grabImageFromView:successButton]];
//doesn't work
// [currChallenge setChallengeImage:[UIImageUtils grabImageFromView:timeLeftText]];
[currChallenge setChallengeImage:[UIImageUtils grabImageFromView:challengeText]];
}
and the grabImage from a UIView code
+(UIImage *)grabImageFromView: (UIView *) viewToGrab {
UIGraphicsBeginImageContext(viewToGrab.bounds.size);
[[viewToGrab layer] renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return viewImage;
}
