I have more than 10 images in screen and i want to move each image using CALayer concept. While am trying to move first image,its working. Even when i drag my second image also, its working. But after that when i get back to first image and when i try to move , am struck up. its not working. I dono where it went wrong. Here's ma code
//Assigning Layer to UIImage//
layer = [CALayer layer];
UIImage *image1 = [UIImage imageNamed:[NSString stringWithFormat:@"%@_thumb.png",[tiv imageName]]];
layer.contents = (id)image1.CGImage;
layer.position=CGPointMake(200,200);
layer.frame = CGRectMake(110, 180, 100, 100);
[self.view.layer addSublayer:layer];
[layer needsDisplay];
[self.view.layer needsDisplay];
[layer needsLayout];
//Here i try to move my image//
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
[super touchesMoved:touches withEvent:event];
NSArray *allTouches = [touches allObjects];
int count = [allTouches count];
if (count == 1) {
if (CGRectContainsPoint([layer frame], [[allTouches objectAtIndex:0] locationInView:self.view])) {
layer.position = [[allTouches objectAtIndex:0] locationInView:self.view];
return;
} }
if (count > 1) {
if (CGRectContainsPoint([layer frame], [[allTouches objectAtIndex:-1] locationInView:self.view])) {
layer.position = [[allTouches objectAtIndex:0] locationInView:self.view];
return;
}
}
}
Also ive planned to use single CALayer for multiple images.. When i click an image, it should be placed in that CALayer and when i click another, the same CALayer should take the latter one. So tat whenever i drag an image it should move(no matter how many images r there) . Do u think this concept will work out or is there any other idea???
My concept may seems to be a basic one. Am new to this environment n so kindly help me..
