发行NSTimer iPhone? [英] Releasing an NSTimer iPhone?

问题描述

我在.h中声明了一个NSTimer，在/m的viewDidLoad中声明了代码:

I have an NSTimer declared in my .h and in the viewDidLoad of the /m I have the code:

timer = [NSTimer scheduledTimerWithTimeInterval:kComplexTimer target:self selector:@selector (main) userInfo:nil repeats:YES];

我也有[定时器发布]；在我的dealloc中.

I also have [timer release]; in my dealloc.

但是，当我退出视图并返回视图时，计时器实际上并没有释放，它的速度提高了一倍！我该如何解决&我在做什么错??

However when I exit the view and return to it, the timer has not in fact released, it has doubles in speed! How do I solve this & what am I doing wrong???

谢谢

推荐答案

很好的回答，但是很好地检查时间是否为零，以避免不必要的异常.

Nice Answer , but good to check whether the time is nil or not to avoid unwanted exception..

if( timer ! = nil )
{
  [timer invalidate];
  timer = nil;
}

谢谢...
