相关疑难解决方法(0)

1)我的plist配置提供backgroundmode:

<key>UIBackgroundModes</key>
<array>
    <string>fetch</string>
</array> 

2)didFinishLaunchingWithOptions我有:

[[UIApplication sharedApplication] setMinimumBackgroundFetchInterval:1.0];

3)我UIApplicationDelegate在代表中宣布了协议.

4)我实现了以下方法,但它永远不会被触发.(仅当我使用"XCode-> Debug-> Simulate Background Fetch"模拟获取时才有效.)

-(void)application:(UIApplication *)application performFetchWithCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler

为什么？这是DP5 beta错误吗？我应该雷达吗？
