NSTimer的内存泄漏?

我正在开发一款应用程序,它基本上都运行良好。但显然还不够好。当运行“泄漏”仪器时,我看到NSTimer发现了很多泄漏。

使用UISwitch启动和停止NSTimer。每次开关切换到“OFF”时都会发生内存泄漏

//PlayView.h
@interface PlayView : UIViewController {
  NSTimer *autoTimer;   
  // other things
}

@property (nonatomic, retain) NSTimer *autoTimer;
// etc...


//PlayView.m
#import "PlayView.h"
@implementation PlayView
@synthesize autoTimer;  


- (IBAction) toggleEnabledForSwitch1: (id) sender {  
    if (switch1.on) {
        self.autoTimer = [NSTimer scheduledTimerWithTimeInterval:0.5
                target:self
                selector:@selector(updateCounter:)
                userInfo:nil
                repeats:YES];

    }

    else {
        restart = 1;
        [self.autoTimer invalidate];
        self.autoTimer = nil;       
    [self.autoTimer release];
    }
}


- (void)updateCounter:(NSTimer *)theTimer {
  // Do a bunch of stuff
}

可能导致这种情况的原因是什么?我确定它一定是简单的,我只是想念它......
