好吧，我采用了最初制作的iOS stumbler应用here
后来here
并添加了一大堆功能，如用户定义的间隔等实时扫描等。
好吧，除了实际扫描到一定程度之外，一切都运行良好。
由于该工具的性质，它只能在越狱手机上运行，因此也无法真正在模拟器上运行（好吧，我用它来测试GUI和其他东西但不是实际的扫描。）
我的问题是，扫描仪运行通常3-4分钟后，我得到EXC_BAD_ACCESS(code=2, address=0x....)
我已经阅读了有关使用僵尸等各种线程，我已经在设置下启用它但无济于事。
我目前的设置是：
xcode 4.6在iphone 4 5.1.1和4s 6.1.1以及4s 5.1.1上的另一位朋友上运行，结果相同。
除了我自己调用的日志之外没有控制台输出，这表示在扫描循环结束后会导致崩溃。 这是扫描循环：
-(void)collectData{
if([[RefresherSingleton sharedRefresher].refresh isEqualToString:@"NO"]){
return;
}
LogInfo(@"Current ESSID:%@",ESSID);
network=[self getNetwork:ESSID];
NSNumber *RSSI=[network objectForKey:@"RSSI"];
NSNumber *noise=[network objectForKey:@"NOISE"];
NSString *time=[dateFormatter stringFromDate:[NSDate date]];
if(!RSSI)
RSSI=[NSNumber numberWithInt:666];
if(!noise)
noise=[NSNumber numberWithInt:666];
if(!time)
time=@"";
NSDictionary *data = [[NSDictionary alloc] initWithObjectsAndKeys:time,@"Time",RSSI, @"RSSI", noise, @"Noise",BSSID,@"BSSID",channel,@"Channel", nil];
[[DataCollection sharedDataCollection].dataCollection addObject:data];
LogInfo(@"%@",data);
//pass the data directly to processData
[self processData];
int delay=[[NSUserDefaults standardUserDefaults] stringForKey:@"interval_preference"].integerValue;
LogInfo(@"Delay set to %d",delay);
if(delay>1)
[self performSelector:@selector(collectData) withObject:nil afterDelay:delay-1];
else
[self performSelector:@selector(collectData) withObject:nil afterDelay:0];
LogInfo(@"About to loop");
[[NSRunLoop currentRunLoop] run];
LogInfo(@"Should have looped");
}
我在代码等上使用ARC .. 循环运行很长时间然后崩溃。 关于如何缩小范围的任何建议？ 这也是iphone崩溃日志：

我不得不从日志中删除相当多的内容，因为它太长了但是我会在需要时链接它
答案 0 :(得分：0)
看起来它可能是堆栈溢出;你发生了无限（间接）递归。 [[NSRunLoop currentRunLoop] run];正在调用您的方法，该方法会调用[[NSRunLoop currentRunLoop] run];等。请尝试从您的方法中删除对[[NSRunLoop currentRunLoop] run];的调用。 （只需在方法结束时返回，无论如何它都会返回到runloop。）
答案 1 :(得分：0)
一旦我改为使用GCD调用而不是使用递归循环，应用程序一直稳定下来:)
这是我用过的：
一旦按下开始按钮，从GUI开始：
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void){
[[ScannerSingleton sharedScanner]scanCurrentNetwork];
});
这会调用一直保持运行的扫描方法，直到按下停止按钮：）
一旦我修复了这个并在应用程序的其他几个区域实现了GCD，它就会更顺畅：D
