Applied UILongPressGestureRecongnizer
on one view,
Check below code for reference..
@interface ViewController ()
{
UIRotationGestureRecognizer *rotationGestureRecognizer6;
}
- (void)viewDidLoad {
//--------Added LongPress Gesture----------//
UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc]
initWithTarget:self
action:@selector(handleLongPress:)];
longPress.minimumPressDuration = 2.0;
[view6 addGestureRecognizer:longPress];
rotationGestureRecognizer6 = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(handleRotationWithGestureRecognizer:)];
}
#pragma mark - UILongPressGesture Handler Method
-(void)handleLongPress:(UILongPressGestureRecognizer *)sender {
if (sender.state == UIGestureRecognizerStateEnded) {
NSLog(@"UIGestureRecognizerStateEnded");
}
else if (sender.state == UIGestureRecognizerStateBegan){
NSLog(@"UIGestureRecognizerStateBegan.");
[view6 addGestureRecognizer:rotationGestureRecognizer6];
}
}
#pragma mark - UIRotationGesture Handler Method
-(void)handleRotationWithGestureRecognizer:(UIRotationGestureRecognizer *)recognizer {
UIView *view = [recognizer view];
[view setTransform:CGAffineTransformRotate([view transform], [recognizer rotation])];
}
Even I had tried adding Rotation Gesture in other states of UILongPressGestureRecongnizer
such as UIGestureRecognizerStateRecognized
,UIGestureRecognizerStateChanged
,UIGestureRecognizerStatePossible
. Not a single one worked for me.
What problem I am facing is, Once logpress gesture detects, it is not adding rotation gesture for the same finger touch. I must need to left that finger touch and again when I tried to rotate it will work well. But I want to allow user to start rotation as soon as longpress gesture detect.
Any help is appreciated! Thanks in advance!
