Iphone 等待一个方法完成，然后再启动另一个方法
假设我有两个连续的方法，Iphone 等待一个方法完成，然后再启动另一个方法,iphone,objective-c,ios,cocos2d-iphone,Iphone,Objective C,Ios,Cocos2d Iphone,假设我有两个连续的方法，methodA和methodB（methodB在methodA的末尾被调用），我需要在开始methodB之前完全完成methodA的过程： -(void)methodA { //do some very heavy computation here [self methodB]; } -(void)methodB { //this method performs some animation } methodA需要大量的处理能力，并且需要
methodAmethodBmethodBmethodAmethodBmethodA-(void)methodA {
//do some very heavy computation here
[self methodB];
}
-(void)methodB {
//this method performs some animation
}
methodAmethodB这是实际代码： 代码非常杂乱无章。有很多代码已经被注释掉了，所以请注意。我有时会测试一些东西，然后评论出来，以备以后需要 发生的情况如下：它以
