ios推送通知终止应用程序

Question

我想在推送通知上单击查看按钮时启动我的应用程序，但如果应用程序不在后台，我的应用程序就会终止。

这是来自控制台的错误信息。

，这是我didFinishlaunchWithOptions

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

NSLog(@"didFinishLaunchingWithOptions"); 
viewController.webView = webView; 
[viewController.view addSubview:webView]; 


// read from UISupportedInterfaceOrientations (or UISupportedInterfaceOrientations~iPad, if its iPad) from -Info.plist 
NSArray* supportedOrientations = [self parseInterfaceOrientations: 
              [[[NSBundle mainBundle] infoDictionary] objectForKey:@"UISupportedInterfaceOrientations"]]; 

// read from PhoneGap.plist in the app bundle 
NSDictionary *temp = [[self class] getBundlePlist:@"PhoneGap"]; 
settings = [[NSDictionary alloc] initWithDictionary:temp]; 

viewController = [ [ PhoneGapViewController alloc ] init ]; 

NSNumber *useLocation   = [settings objectForKey:@"UseLocation"]; 
NSString *topActivityIndicator = [settings objectForKey:@"TopActivityIndicator"]; 


// The first item in the supportedOrientations array is the start orientation (guaranteed to be at least Portrait) 
[[UIApplication sharedApplication] setStatusBarOrientation:[[supportedOrientations objectAtIndex:0] intValue]]; 

// push notification 
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)]; 
// end of push notification 

这个代码是从所谓的AppDelegate.m

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


NSArray *keyArray = [launchOptions allKeys]; 
if ([launchOptions objectForKey:[keyArray objectAtIndex:0]]!=nil) 
{ 
    NSURL *url = [launchOptions objectForKey:[keyArray objectAtIndex:0]]; 
    self.invokeString = [url absoluteString]; 
    NSLog(@"listingApp launchOptions = %@",url); 
} 

return [super application:application didFinishLaunchingWithOptions:launchOptions]; 
} 

请帮助另一位代表文件的开头？ 许多感谢感谢:)

Answer 1

您似乎在字典上调用absoluteString，在那里您可能打算在NSURL对象上执行此操作。

重新您最新的代码示例：

你正在做的事情很奇怪，试图找到在launchOptions字典中的第一个关键。这不是如何使用字典。您应该使用的按键（上市here下启动选项键）直接，就像这样：

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

    NSURL *url = [launchOptions objectForKey:UIApplicationLaunchOptionsURLKey] 

    if (url) 
    { 
     self.invokeString = [url absoluteString]; 
     NSLog(@"listingApp launchOptions = %@", url); 
    } 

    return [super application:application didFinishLaunchingWithOptions:launchOptions]; 
} 

Answer 2

看起来你还没有实现的方法

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo

当收到通知时调用此方法。
