IOS 消息推送處理

當一個ios 的push消息到來的時候，有兩種狀況，apple爲咱們提供了2個回調api來處理:

1.app 未啓動狀態

application:didFinishLaunchingWithOptions
//launchOptions 包含 推送 playload 信息
if (launchOptions != nil)
    {
        NSDictionary *dictionary = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
        if (dictionary != nil)
        {
            NSLog(@"Launched from push notification: %@", dictionary);
    //根據 playload內容處理
            [self addMessageFromRemoteNotification:dictionary updateUI:NO];
        }
    }

2.app 運行狀態

- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo
{
    NSLog(@"Received notification: %@", userInfo);
    [self addMessageFromRemoteNotification:userInfo updateUI:YES];
}

自定義消息內容

{
    "aps": {
        "alert": "hello  users update .",
        "badge": 1,
        "sound": "default"
    },
    "page":"chat"
}
能夠在消息自定義字段內容，而後在回調函數裏判斷處理
