如何在IOS動作擴展中託管應用程序發送數據到應用程序擴展

Question

我已經完成了示例動作擴展應用程序。我無法獲得主機應用程序請求data.i認爲是有這個代碼的一些問題。

主機應用程序請求的代碼

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]; 

應用擴展代碼

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); 

    }]; 

我不知道什麼是錯上面的代碼，任何人都可以幫我..謝謝

Answer 1

打開應用組並使用NSUserDefaults

1. 打開應用程序組和在二者宿主靶和擴展目標功能添加組名

2. 輸入在主機應用程序源設置數據

 

    //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);
