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];
}
