How do I check to see if my subview is being touched?
- by Amy
I went through this tutorial about how to animate sprites:
http://icodeblog.com/2009/07/24/iphone-programming-tutorial-animating-a-game-sprite/
I've been attempting to expand on the tutorial by trying to make Ryu animate only when he is touched. However, the touch is not even being registered and I believe it has something to do with it being a subview. Here is my code:
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
UITouch *touch = [touches anyObject];
if([touch view] == ryuView){
NSLog(@"Touch");
} else {
NSLog(@"No touch");
}
}
-(void) ryuAnims{
NSArray *imageArray = [[NSArray alloc] initWithObjects:
[UIImage imageNamed:@"1.png"],
[UIImage imageNamed:@"2.png"],
[UIImage imageNamed:@"3.png"],
[UIImage imageNamed:@"4.png"],
[UIImage imageNamed:@"5.png"],
[UIImage imageNamed:@"6.png"],
[UIImage imageNamed:@"7.png"],
[UIImage imageNamed:@"8.png"],
[UIImage imageNamed:@"9.png"],
[UIImage imageNamed:@"10.png"],
[UIImage imageNamed:@"11.png"],
[UIImage imageNamed:@"12.png"],
nil];
ryuView.animationImages = imageArray;
ryuView.animationDuration = 1.1;
[ryuView startAnimating];
}
-(void)viewDidLoad {
[super viewDidLoad];
UIImageView *image = [[UIImageView alloc] initWithFrame:
CGRectMake(100, 125, 150, 130)];
ryuView = image;
ryuView.image = [UIImage imageNamed:@"1.png"];
ryuView.contentMode = UIViewContentModeBottomLeft;
[self.view addSubview:ryuView];
[image release];
}
This code compiles fine, however, when touching or clicking on ryu, nothing happens. I've also tried
if([touch view] == ryuView.image)
but that gives me this error: "Comparison of distinct Objective-C type 'struct UIImage *' and 'struct UIView *' lacks a cast." What am I doing wrong?
