我有几个使用多点触摸可以在iphonescreen上移动的uiimages。问题是我想要将它们分成两个“团队”,一个是我选择的区域内的一个“团队”,一个是我可以在整个屏幕上移动的“团队”。关于多点触摸的问题
我的问题是如何使用触摸方法(touchesbegan,touchesended,touchesmoved)为两个uiimage“团队”和他们的cgpoints没有来自两个“团队”的cgpoints相互交叉和给错误的uiimages错误的位置上屏幕。第一个“团队”使用touchesbegan,touchesmoved和touchesended方法。第二个“团队”只使用touchesended方法。
这是我的代码。我希望2“团队”交叉彼此在touchesended方法
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
//1st team
for(UITouch *touch in touches){
// Send to the dispatch method, which will make sure the appropriate subview is acted upon
[self getRubyAtPoint:[touch locationInView:self.view]forEvent: nil];
}
}
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
NSLog(@"touchesEnded");
//1st team
// Enumerates through all touch object
for (UITouch *touch in touches) {
// Sends to the dispatch method, which will make sure the appropriate subview is acted upon
[self dispatchTouchEndEvent:[touch view] toPosition:[touch locationInView:self.view]];
}
//2nd team
UITouch *touch = [touches anyObject];
CGPoint currentTouch = [touch locationInView:self.view];
[self getPieceAtPoint:currentTouch];
}
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
//1st team
NSLog(@"touchesMoved");
// Enumerates through all touch objects
for (UITouch *touch in touches) {
// Send to the dispatch method, which will make sure the appropriate subview is acted upon
[self dispatchTouchEvent:[touch view] toPosition:[touch locationInView:self.view]];
}
}
正是...我要上第一队的dispatchTouchEndEvent只有行为和getPieceAtPoint到2号球队在touchesended方法仅行为。一个标签?好吧,这听起来像个好主意。我会试试看,并让你知道。 thanx :) – iphonedevonthemake 2011-04-13 03:20:25
