UIImageView default userInteraction is false, so u are just enable userInteraction is True for both image view.
Why won't my ImageView move?
質問
All in all I am trying to get a result when one image touches another image. That is not the problem I am having though. I can't get the UIImageView to even move when I click on it and drag. Below is the code I am using! Please let me know if you can help me! Thanks!
.h
{
IBOutlet UIImageView *image1;
IBOutlet UIImageView *image2;
}
@property (nonatomic, retain) UIImageView *image1;
@property (nonatomic, retain) UIImageView *image2;
-(void)collision;
.m
@synthesize image1, image2;
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch1 = [touches anyObject];
[self collision];
if ([touch1 view] != self.image1) {
return;
}
}
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch1 = [touches anyObject];
// If the touch was in the placardView, move the placardView to its location.
if ([touch1 view] == self.image1) {
CGPoint location = [touch1 locationInView:image1];
self.image1.center = location;
return;
}
}
-(void)collision
{
if (CGRectIntersectsRect(image1.frame, image2.frame)) {
NSLog(@"Touched");
}
}
** I was able to get the code to work where I am able to move the UIImageView.
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch1 = [[event allTouches] anyObject];
image1.center = [touch1 locationInView:self.view];
return;
}
The only problem with this is that where ever I touch on the screen the image moves to that location. How may I have it where you have to touch the actual UIImageView to move it? Thanks!!
