であると考えている個々の規模で
UIPanGestureRecognizer *imagePanGesture = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(moveImage:)];
[imagePanGesture setMinimumNumberOfTouches:1];
[imagePanGesture setMaximumNumberOfTouches:1];
[tempImageView addGestureRecognizer:imagePanGesture];
UIPinchGestureRecognizer *pinchGesture = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(scaleImage:)];
[tempImageView addGestureRecognizer:pinchGesture];
UIRotationGestureRecognizer *rotationGesture = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(rotateImage:)];
[tempImageView addGestureRecognizer:rotationGesture];
と
- (void)scaleImage:(UIPinchGestureRecognizer *)recognizer
{
if([recognizer state] == UIGestureRecognizerStateEnded)
{
previousScale = 1.0;
return;
}
CGFloat newScale = 1.0 - (previousScale - [recognizer scale]);
CGAffineTransform currentTransformation = [recognizer view].transform;
CGAffineTransform newTransform = CGAffineTransformScale(currentTransformation, newScale, newScale);
[[recognizer view] setTransform:newTransform];
previousScale = [recognizer scale];
}
- (void)rotateImage:(UIRotationGestureRecognizer *)recognizer
{
if([recognizer state] == UIGestureRecognizerStateEnded) {
previousRotation = 0.0;
return;
}
CGFloat newRotation = 0.0 - (previousRotation - [recognizer rotation]);
CGAffineTransform currentTransformation = [recognizer view].transform;
CGAffineTransform newTransform = CGAffineTransformRotate(currentTransformation, newRotation);
[[recognizer view] setTransform:newTransform];
previousRotation = [recognizer rotation];
}
ありがとう!これは私が探しているワットです。 – RockBaby
