iphone EXC_BAD_ACCESS (SIGBUS) on device
Well, I've taken the iOS stumbler app that was first made here
and later here
and added a whole bunch of functionality such as real time scanning on user defined intervals and etc etc.
Well, everything runs fine except the actual scanning up to a point.
Due to the nature of the tool it only runs on jailbroken phones and as such also cannot be really run on the simulator (well, I use it to test GUI and other stuff but not actual scanning.)
My problem is that after the scanner has run for usually 3-4 minutes, I get a EXC_BAD_ACCESS(code=2, address=0x....)
I've read through all kinds of threads regarding using zombies and such and I have enabled it under settings but to no avail.
My current settings are:
xcode 4.6 running on both an iphone 4 5.1.1 and 4s 6.1.1 as well as another friend on an 4s 5.1.1 with same results.
There is no console output except my own logs I call which indicate that after the end of a scan loop something causes the crash. Here is the scan loop:
-(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");
}
I am using ARC on the code etc.. The loop runs fine for quite a while and then just crashes. Any advice on how I could narrow it down or so? Here is also the iphone crash log:

I had to cut away quite a bit from the log as it's too long but I'll link it if needed

It looks like it could be a stack overflow; you've got infinite (indirect) recursion happening. [[NSRunLoop currentRunLoop] run]; is calling your method, which calls [[NSRunLoop currentRunLoop] run];, etc. Try removing the call to [[NSRunLoop currentRunLoop] run]; from your method. (Just return at the end of your method, and it will return to the runloop anyway.)

Jesse RusakOnce I changed to using GCD calls instead of a loop using recursion the app has been rock steady :)
here is what I used:
from the GUI once start button is pressed:
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void){
[[ScannerSingleton sharedScanner]scanCurrentNetwork];
});
this calls the scan method which keeps running until the stop button is pressed :)
once i fixed that and implemented GCD on a few other areas of the app as well it's been much much smoother :D
