iPhone仅在设备未连接到xcode时崩溃，如何了解崩溃日志? [英] iPhone crash only when device not connected to xcode, how to understand the crash log?

问题描述

在运行ios 5的设备上，我的应用程序运行良好，但是在运行ios 4.2.1的设备上，出现此崩溃. 奇怪的是，仅当未连接到xcode时，设备才会崩溃. 从xcode运行时，它可以工作，但是当我在没有xcode的情况下运行时，应用程序一直运行到我调用该方法为止:

On a device running ios 5 my app works great, but on a device running ios 4.2.1 i get this crash. The strange thing is that the device crash only when NOT connected to xcode. When run from xcode it work but when i run it without xcode the app is working till the moment i call the method:

- (void)startLocationUpdates
{
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBestForNavigation;
    self.locationManager.distanceFilter = 1;
    self.locationManager.delegate = self;
    [self.locationManager startUpdatingLocation];
}

推荐答案

您确定self一直在使用中并且在销毁self之前设置了self.locationManager.delegate = nil;吗?

Are you sure that self is living all the time you use it and you set self.locationManager.delegate = nil; before you destroy self?
