如何在Xcode上的IBAction代码块后调用方法
如何在Xcode上的IBAction代码块后调用方法
提问于 2013-04-09 09:40:56
我制作了一个iPhone棋盘游戏。它有能力选择是用户想玩多人还是单玩家。
我用UIButton来做棋盘上的零件。
我有一件事要修复:在单玩家模式下，我实现了AI的转换为UIButton的IBAction。但是，在这种情况下，玩家1的移动和玩家2的移动之间没有时间。同时被执行。。
，我想这样做：让人类立即移动，然后计算机为他的移动而思考。我不想让这两个动作结合在一起，在那台电脑考虑移动之后。
我知道问题在于，因为游戏读取了IBAction中的整个代码块，然后他显示了结果，但我不知道如何解决这个问题。
有什么建议吗？
如果您需要它，我可以展示代码，但我想(我也希望如此)，您将理解我的意思。
由于请求的评论，这是代码..。

turno = [self whosTurn];
UIButton *bottoneCampoGioco = sender;
UIButton *bottoneIntelligente;
//Checks if it's Human's turn
if (turno == 0) {
int valoreBottone = [bottoneCampoGioco.currentTitle intValue];
if(valoreBottone< 10){
//if controls are ok, it changes value of human's chosen button
if((bottoneCampoGioco.currentTitleColor != [UIColor greenColor])){

如果我正确理解，您希望在延迟后执行代码的AI部分。如果可以将代码重构为另一个方法，则可以使用performSelector:withObject:afterDelay:，如下所示：
[self performSelector:@selector(aiMove) withObject:nil afterDelay:2.0];这将在2秒后运行该方法。或者您可以使用GCD的dispatch_after，如下所示。将要在延迟后运行的代码放置到块中。
double delayInSeconds = 2.0;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
//
//Your code goes here
//
