關於多點觸摸的問題

Question

我有幾個使用多點觸摸可以在iphonescreen上移動的uiimages。問題是我想要將它們分成兩個「團隊」，一個是我選擇的區域內的一個「團隊」，一個是我可以在整個屏幕上移動的「團隊」。

我的問題是如何使用觸摸方法（touchesbegan，touchesended，touchesmoved）爲兩個uiimage「團隊」和他們的cgpoints沒有來自兩個「團隊」的cgpoints相互交叉和給錯誤的uiimages錯誤的位置上屏幕。第一個「團隊」使用touchesbegan，touchesmoved和touchesended方法。第二個「團隊」只使用touchesended方法。

這是我的代碼。我希望2「團隊」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]]; 

} 
    }

如果我理解鴕鳥政策，你問如何保持方法，如getPieceAtPoint作用於錯了隊。

我想我會爲每個團隊添加一個獨特的標籤範圍，然後在對其採取行動之前對其進行檢查。

喜歡的東西：

UITouch *touch = [touches anyObject]; 
if ([touch view].tag>=TEAM_TWO_BASE_TAG) 
{ 
    CGPoint currentTouch = [touch locationInView:self.view];  
    [self getPieceAtPoint:currentTouch]; 
}
