我制作了一个应用程序,我想让它兼容多点触控。我试过环顾四周,但答案并不特定于我。这是我所做的:
1)我的编码:
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
[self touchesMoved:touches withEvent:event];
if (gameState == kGameStatePaused) {(gameState = kGameStateRunning);}
}
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
if(gameState == kGameStateRunning) {
UITouch *touch = [[event allTouches] anyObject];
CGPoint location = [touch locationInView:touch.view];
if(location.x > 400) {
CGPoint yLocation = CGPointMake(playerPaddle.center.x, location.y);
playerPaddle.center = yLocation;
}
if (gameStyle == kGameStyleTwoP) {
if(location.x < 100) {
CGPoint yLocation2 = CGPointMake(computerPaddle.center.x, location.y);
computerPaddle.center = yLocation2;
}
}
}
2)我已经进入界面生成器并选中了启用多点触控的框
3)我构建并运行我的应用程序,它可以正常打开,当我去测试多点触控时,我按住“选项键”并单击并移动鼠标
4)(我试图让 computerPaddle 和 playerPaddle 都移动)但一次只有一个作品
我必须尝试修复它,但我不明白我哪里出错了。
任何帮助都是有用的。谢谢。
