我看任何方法如何可能觸摸圖像和改變你的位置。但同樣的事情需要在屏幕上顯示20個圖像。所以我用不同的標籤生成20個UIimageViews。但我仍然不知道如何通過標記選擇這些UIimageViews。如何通過標籤選擇和移動UIimageViews?
有我的代碼:
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
}
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [[event allTouches] anyObject];
CGPoint location = [touch locationInView:self.view];
imageView = (UIImageView *)[imageView viewWithTag:imageView.tag] ;
NSLog(@"%d",imageView.tag);
imageView.center = location;
}
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
imageView.tag = arc4random() % 19;
}
- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event {
}
- (void)viewDidLoad
{
[super viewDidLoad];
imageView = nil;
for (int i; i<19; i++) {
int randX = arc4random() % 240;
int randY = arc4random() % 368;
imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"img_1.png"]];
imageView.frame = CGRectMake(randX, randY, 80, 92);
imageView.tag = i;
//NSLog(@"%d",imageView.tag);
[self.view addSubview:imageView];
}
}
感謝您閱讀
「viewWithTag」有什麼問題? – Saphrosit 2012-03-09 14:06:35
