[問題] ios notification

[rainsky0617 (rainsky)]

        小弟最近剛寫了一隻小APP，關於IOS NOTIFICATION，在APP有開啟時

或在背景執行時，收到推播通知，點擊後會進入特定VIEWCONTROLLER(include webview、

navigation bar 、 image view)，以上功能都能正常運作，但是當APP沒開啟時，點擊後

雖然也會轉定特定的VIEWCONTROLLER，但是WEBVIEW區塊卻白茫茫一片，navigation bar

 、 image view都有正常顯示，此一WEBVIEW的網址，先寫死在WEBVIEW中(方便測試)

請各位高手前輩幫幫忙給點建議囉~謝謝各位前輩先進們~!!OTZ....

CODE 如下:  pushview 為點擊推播訊息後所要顯示的VIEWCONTROLLER


網頁網址目前先寫死在pushview.m裏




AppDelegate.m



-(void)postNotificationToPresentPushMessagesVC {

    [[NSNotificationCenter defaultCenter]
postNotificationName:@"HAS_PUSH_NOTIFICATION" object:nil];

}



- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

    //註冊推播

    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) {

        [[UIApplication sharedApplication]
registerUserNotificationSettings:[UIUserNotificationSettings
settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert |
UIUserNotificationTypeBadge) categories:nil]];

        [[UIApplication sharedApplication] registerForRemoteNotifications];

      }

    else {

        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:

         (UIUserNotificationTypeBadge | UIUserNotificationTypeSound |
UIUserNotificationTypeAlert)];

    }



    // app 如果在沒啟動的狀態下(前景/背景都無)，點"推播通知"後，會將推播資料以
 launchOptions 傳入。

    if (launchOptions) {

        NSDictionary *userInfo = [launchOptions
valueForKey:UIApplicationLaunchOptionsRemoteNotificationKey];

        if (userInfo) {


           [[NSNotificationCenter defaultCenter]
postNotificationName:@"request_aps" object:nil userInfo:userInfo];

            [self
performSelector:@selector(postNotificationToPresentPushMessagesVC)

                       withObject:nil

                       afterDelay:1];

        }

    }

    return YES;

}




ViewController.m

-(void)LoadRequestFromAppDel:(NSNotification*)aNotif

{

//取得推播訊息中的ＵＲＬ

    url=[[[aNotif userInfo] objectForKey:@"aps"] objectForKey:@"url"];

//轉到pushview

   pushview *vc = [self.storyboard
instantiateViewControllerWithIdentifier:@"pushview"];

     [self presentViewController:vc animated:YES completion:nil];

    //將ＵＲＬ放入訊息中心

    [[NSNotificationCenter defaultCenter] postNotificationName:@"request_url"
object:url];

    }



-(void)presentMyViewOnPushNotification {

     NSString *url=@"https://www.google.com";
     [[NSNotificationCenter defaultCenter] postNotificationName:@"request_url"
object:url];

    pushview *pvc = [self.storyboard
instantiateViewControllerWithIdentifier:@"pushview"];

    [self presentViewController:pvc animated:YES completion:nil];

}



-(void) viewDidAppear:(BOOL)animated {



    [super viewDidAppear:animated];



    //調用LoadRequestFromAppDel取出 request_aps object

    [[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(LoadRequestFromAppDel:)name:@"request_aps" object:Nil];



  [[NSNotificationCenter defaultCenter] addObserver:self


 selector:@selector(presentMyViewOnPushNotification)

                                                 name:@"HAS_PUSH_NOTIFICATION"

                                               object:nil];
}

pushview. h

#import <UIKit/UIKit.h>


@interface pushview : UIViewController

@property (weak, nonatomic) IBOutlet UIWebView *pushweb;



@end


pushview.m

- (void) LoadUrl:(NSNotification*) notification

{

    NSString *geturl = [notification object];//通過這個獲取到傳遞的對象

    geturl=@"https://tw.yahoo.com/";

  NSURL *url = [NSURL URLWithString:geturl];

    NSURLRequest *request = [NSURLRequest requestWithURL:url];

   //pushweb 為ＵＩwebview名稱

   [self.pushweb loadRequest:request];

}



- (void)viewDidLoad {

    [super viewDidLoad];

    //調用LoadRequestFromAppDel取出 request_device_token object

    [[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(LoadUrl:) name:@"request_url"object:nil];


}

推 howdiun: 這叫寫死在推播裡，推播沒點就沒有url
→ rainsky0617: 是的，但是點選推播後所顯示的VIEW，並拿不到那個URL
推 kidd0717: 建議你可以貼到github或其他可以貼code的地方 方便閱讀
→ rainsky0617: 謝謝樓上的回覆與建議，已解決囉~!
→ rainsky0617: 我不應該一直用訊息中心傳東西，將pushview 新增一個
→ rainsky0617: @property (nonatomic) NSURL *url在利用pvc.url=xxx
