NSTimer 不会停止
In my application I am using NStimer to call an animation function every 3 seconds. I want to stop this timer and called another event while the timer is still running. Is this possible?
在我的应用程序中，我使用 NStimer 每 3 秒调用一次动画函数。我想停止这个计时器并在计时器仍在运行时调用另一个事件。这可能吗？

@interface
NSTimer *autoTimer;
@implementation
// Start timer
autoTimer = [NSTimer scheduledTimerWithTimeInterval:(3.0)
target:self
selector:@selector(autoTimerFired:)
userInfo:nil
repeats:YES];
// Stop timer:
[autoTimer invalidate];
autoTimer = nil;

First, you want to keep a pointer to the timer
首先，您要保留一个指向计时器的指针
self.packetTimer = [NSTimer timerWithTimeInterval:CONNECTION_TIMEOUT target:self selector:@selector(connectionTimeout:) userInfo:nil repeats:NO];
[[NSRunLoop currentRunLoop] addTimer:packetTimer forMode:NSDefaultRunLoopMode];
If somewhere else in your code you want to cancel it, just call:
如果您想取消代码中的其他地方，只需调用：
[self.packetTimer invalidate];
self.packetTimer = nil;
