如何在IOS动作扩展中托管应用程序发送数据到应用程序扩展

Question

我已经完成了示例动作扩展应用程序。我无法获得主机应用程序请求data.i认为是有这个代码的一些问题。

主机应用程序请求的代码

NSDictionary *request = @{@"username”:@“username”,@“password”:@“password”}; 
      UIActivityViewController *extensionController = [[UIActivityViewController alloc] initWithActivityItems:@[request] applicationActivities:nil]; 
      extensionController.popoverPresentationController.sourceView = self.view; 
     [self presentViewController:extensionController animated:YES completion:nil]; 

应用扩展代码

NSExtensionItem *inputItem = self.extensionContext.inputItems[0]; 

    NSItemProvider *itemprovider = inputItem.attachments[0]; 

    [itemprovider loadItemForTypeIdentifier:(NSString *)kUTTypePropertyList options:nil completionHandler:^(NSDictionary *item, NSError *error) { 

     NSDictionary *results = (NSDictionary *)item; 

     NSLog(@“Host app Request Data=%@",results); 

    }]; 

我不知道什么是错上面的代码，任何人都可以帮我..谢谢

Answer 1

打开应用组并使用NSUserDefaults

1. 打开应用程序组和在二者宿主靶和扩展目标功能添加组名

2. 输入在主机应用程序源设置数据

 

    //use our group user defaults 
    NSUserDefaults *defaults = [[NSUserDefaults alloc] 
    initWithSuiteName:@"group.com.organization.ProductName"]; 

    //set a greeting 
    [defaults setObject:@"username" forKey:@"username"]; 
    [defaults setObject:@"password" forKey:@"password"]; 

    //synchronise 
    [defaults synchronize]; 

SomeExtension.m

 

    //use our group user defaults 
    NSUserDefaults *defaults = [[NSUserDefaults alloc] 
    initWithSuiteName:@"group.com.organization.ProductName"]; 

    //get the greeting  
    NSString *username = [defaults stringForKey:@"username"]; 
    NSString *password = [defaults stringForKey:@"password"]; 

    //check if greeting isn't empty 
    NSLog(@"username = %@/password = %@", username, password);
