我有一个今天的小部件扩展,当我点击一个按钮,它打开了应用程序。我第一次单击按钮并按照代码进行操作时,它会使用自定义URL方案来传递数据。这在AppDelegate中被解析,并且它计算出用什么数据填充ViewControllerViewController使用故事板ID进行实例化。值将应用于其中一个ViewController的属性,然后在viewDidLoad中,其余值将基于Value中传递的值填充。这一切都是第一次。从扩展程序打开应用程序,属性只改变第一次

但是,如果我点击主页按钮,打开通知中心,在我的应用程序中点击一个按钮,然后再次浏览整个过程..我按正常方式浏览代码,所有值都已设置,但当显示ViewController时,值(如UILabel)与第一次相同,但它们应该已更改。

NSString *url = [NSString stringWithFormat:string ://%@", self.expanededTubeLine.lineName ]; 

NSExtensionContext *myExtension=[self extensionContext]; 
[myExtension openURL:[NSURL URLWithString:url] completionHandler:nil]; 

//

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url { 

NSString *tubeLineName = [url host]; 

NSUserDefaults *defaults = [[NSUserDefaults alloc] initWithSuiteName:@"group.koc.extensiontest"]; 

if ([defaults objectForKey:@"weekendData"]) { 

    NSData *tubeData = [[defaults objectForKey:@"weekendData"] copy]; 

    TFLParser *parser = [[TFLParser alloc] initWithData:tubeData]; 
    [parser parseData]; 
    for (int x = 0; x < parser.delayedTubeLines.count; x++) { 

     TubeLine *tl = [[TubeLine alloc] init]; 
     tl = [parser.delayedTubeLines objectAtIndex:x]; 
     if ([tl.lineName isEqualToString:tubeLineName]) { 

      UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil]; 
      TubeLineViewController *tubeLineViewController = [storyboard instantiateViewControllerWithIdentifier:@"TubeLineViewController"]; 
      tubeLineViewController.tubeLine = tl; 


      [self.window.rootViewController presentViewController:tubeLineViewController animated:YES completion:nil]; 
      return YES; 
     } 
    } 
} 

}

//

- (void)viewDidLoad { 
    [super viewDidLoad]; 

    self.tubeLineName.text = self.tubeLine.lineName; 
    self.tubeLineName.font = [UIFont openSansLightFontOfSize:18.0f]; 
    self.tubeLineName.textColor = [UIColor whiteColor]; 
    self.tubeLineName.backgroundColor = self.tubeLine.lineBackgroundUIColor; 
    self.tubeLineName.layer.cornerRadius = 5; 
    self.tubeLineName.clipsToBounds = YES; 

    self.tubeLineMessage.font = [UIFont openSansLightFontOfSize:18.0f]; 
    self.tubeLineMessage.text = self.tubeLine.lineMessage; 
    self.tubeLineMessage.textColor = [UIColor darkGrayColor]; 
}

这听起来像查看已经加载推部件基于控制器之前,所以弹出所有的视图控制器在handleOpenURL:函数中。

[self.viewController.navController popToRootViewControllerAnimated:NO]; 
    if ([self.viewController presentedViewController]) { 
     [self.viewController dismissViewControllerAnimated:NO completion:nil]; 
    }
