ios - didReceiveMessage :(XMPPMessage *)message Not Running Actual Device

Question

我正在开发一款聊天应用。

- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message{}

当App is Background

时，此方法有效并在模拟器中运行时捕获购买断点

但在 Real Device App 中的应用程序中运行时

background mode . its not working in background mode

Answer 1

添加以下代码

UIBackgroundTaskIdentifier bgTask = 0;
UIApplication  *app = [UIApplication sharedApplication];
bgTask = [app beginBackgroundTaskWithExpirationHandler:^{
    [app endBackgroundTask:bgTask];
}];

在你的

- (void)applicationDidEnterBackground:(UIApplication *)application

然后这个方法

- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message{}

也将在后台工作。
