iPhone延迟后调用功能 [英] iPhone calling a function after a delay

问题描述

我有一些代码，其中我将精灵显示N秒钟.N秒钟后，此框将被删除，我想调用一个我可以选择的函数.例如，我想在10秒内调用showBoxEnded.

I have some code where I display a sprite for N number of seconds. This box is removed after N seconds and I'd like to call a function that I can select. For example, in 10 seconds I want to call showBoxEnded.

我在这里看了看，发现可以使用SEL功能了.我写道:

I looked on here and saw I can use the SEL function. I wrote:

-(void)caller:(id)sender
{
    NSLog(@"Function Called!");
}

我可以调用callFunc来设置将被调用的功能:

I can call callFunc in order to set the function that will be called:

-(void) callFunc:(SEL)func;

但是，当我尝试这样做时，我的函数从不被调用.我在这里想念什么吗?是否可能像C ++中那样?

However, when I try this, my function is never called. Am I missing something here? Is this possible like it is in C++?

是否可以仅将SEL函数作为参数传递给函数?

Is it possible to just pass the SEL function as a parameter to a function?

谢谢！

推荐答案

您在寻找 [self performSelector:@selector(myfunc)withObject:afterDelay:];
