我的应用程序在“applicationDidEnterBackground”处使用带有此代码的后台任务:
// 10min background task
UIBackgroundTaskIdentifier myLongTask;
myLongTask = [[UIApplication sharedApplication]
beginBackgroundTaskWithExpirationHandler:^{
[locationMgrInstance timerSet];
}];
// cell change
[locationMgrInstance startMonitoringSignificantLocationChanges];
它在 iOS 6 上运行良好......但是!iOS 7 在 180 秒后抛出断言。帮助!
