你需要做以下...

您需要打开后台模式。

在 AppDelegate 中，添加此代码以在后台运行应用程序

创建属性

@property (nonatomic, assign) UIBackgroundTaskIdentifier backgroundTask;

然后做以下...

- (void)applicationDidEnterBackground:(UIApplication *)application {

    self.backgroundTask = [application beginBackgroundTaskWithExpirationHandler:^{
        DLOG(@"End of tolerate time. Application should be suspended now if we do not ask more 'tolerance'");

    }];

    if (self.backgroundTask == UIBackgroundTaskInvalid) {
        DLOG(@"This application does not support background mode");
    } else {
        //if application supports background mode, we'll see this log.
        DLOG(@"Application will continue to run in background");
    }

}
