iOS遠程推送之(一)：APNs原理和基本配置
iOS遠程推送之(二)：角標applicationIconNumber設置

點擊橫幅啟動應用

我們應用的啟動方式有很多種，主要的方式如下：

• 一種是在HomeScreen上正常手動點擊圖標打開進入到應用中
• 一種是通過其他應用調起該應用
• 一種是通過點擊通知橫幅來啟動應用

簡說:

• 第一種很正常的在didFinishLaunchingWithOptions里面處理就OKay的
• 第二種是通過openURL的方式打開的，那么在對應的openURL方法來處理相關內容的
• 第三種是通過判斷didFinishLaunchingWithOptions中的參數launchOptions中的UIApplicationLaunchOptionsRemoteNotificationKey來處理相關的消息內容

PS: UIApplicationLaunchOptionsRemoteNotificationKey的說明如下：

The presence of this key indicates that a remote notification is available for the app to process. 
釋義：這個鍵的存在表明,遠程通知是可供應用的過程。
The value of this key is an NSDictionary containing the payload of the remote notification. 
釋義：這個字典當中的這個鍵對應的值包含了推送消息負載(payload)
See the description of application:didReceiveRemoteNotification: for further information about handling remote notifications.
釋義：看這個方法的描述能夠進一步的了解處理鹽城通知的相關信息

代碼說明：

• 第一種：didFinishLaunchingWithOptions

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.window.rootViewController = [[ViewController alloc] init];
    [self.window makeKeyAndVisible];
    
//code here...
    return YES;
}

• 第二種openURL:

//這個是最新的iOS9之后的
-(BOOL) application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options
{
    [[KODSDK defaultSDK]  kodDealWithApplication:app openURL:url sourceApplication:options[@"UIApplicationOpenURLOptionsSourceApplicationKey"] annotation:options[@"UIApplicationOpenURLOptionsOpenInPlaceKey"]];
    return YES;
}

//這個是iOS9之前的，9之后廢棄
-(BOOL) application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    [[KODSDK defaultSDK]  kodDealWithApplication:application openURL:url
                                       sourceApplication:sourceApplication annotation:annotation];
    
    return YES;
}

• 第三種：UIApplicationLaunchOptionsRemoteNotificationKey

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.window.rootViewController = [[ViewController alloc] init];
    [self.window makeKeyAndVisible];
    
    NSDictionary *userInfo = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey];
    if (userInfo != nil) {
        //如果有值，說明是通過遠程推送來啟動的
        //[UIApplication sharedApplication].keyWindow是拿不到值的
    }
    return YES;
}

PS：以上中keyWindow是拿不到值的，所以這里的話我一般的做法是在根控制器創建完成之后發送一個通知出來，然后Appdelegate中接收通知，然后實現跳轉對應的控制器或者界面
