Swift实现FBSDKAppInviteDialogDelegate不起作用 [英] Swift implementation of FBSDKAppInviteDialogDelegate not working

问题描述

我正在尝试在我的类上实现协议FBSDKAppInviteDialogDelegate，但xcode显示了一个错误，表示Type MyClass不符合协议FBSDKAppInviteDialogDelegate'

协议的定义：

  @protocol FBSDKAppInviteDialogDelegate< NSObject> 
 
 / *！ 
 @abstract发送给代理，当应用程序邀请完成没有错误。 
 @param appInviteDialog完成的FBSDKAppInviteDialog。 
 @param结果对话框的结果。这可能是零或空。 
 * / 
  - （void）appInviteDialog：（FBSDKAppInviteDialog *）appInviteDialog didCompleteWithResults：（NSDictionary *）results; 
 
 / *！ 
 @abstract应用程序邀请遇到错误时发送给代理。 
 @param appInviteDialog完成的FBSDKAppInviteDialog。 
 @param错误错误。 
 * / 
  - （void）appInviteDialog：（FBSDKAppInviteDialog *）appInviteDialog didFailWithError :(（NSError *）错误; 
 
 @end 
  

我的代码：

我的类的定义

  class MyClasse：UITableViewController，FBSDKAppInviteDialogDelegate 
  

呼叫邀请对话框：

  var inviteDialog：FBSDKAppInviteDialog = FBSDKAppInviteDialog（）
 if（inviteDialog.canShow（））{
 let appLinkUrl：NSURL = NSURL（string：http://mylink.com）！ 
 let previewImageUrl：NSURL = NSURL（string：http://mylink.com/image.png）！ 
 
 var inviteContent：FBSDKAppInviteContent = FBSDKAppInviteContent（appLinkURL：appLinkUrl）
 inviteContent.previewImageURL = previewImageUrl 
 
 inviteDialog.content = inviteContent 
 inviteDialog.delegate = self 
 inviteDialog.show（）
} 
  

procol方法的实现： / p>

  // FBSDKAppInviteDialogDelegate的功能
 func appInviteDialog（appInviteDialog：FBSDKAppInviteDialog !, didCompleteWithResults results：NSDictionary！）{
 //我的代码
} 
 // FBSDKAppInviteDialogDelegate的功能
 func appInviteDialog（appInviteDialog：FBSDKAppInviteDialog !, didFailWithError error：NSError！）{
 //我的代码在这里
} 
  

邀请对话框工作。但是没有协议，我无法获得结果。

我在这里缺少什么？

解决方案

问题在于NSDictionary。以下内容适用于我：

  func appInviteDialog（appInviteDialog：FBSDKAppInviteDialog !, didCompleteWithResults results：[NSObject：AnyObject]！）{ 
 println（完全邀请没有错误）
} 
 
 func appInviteDialog（appInviteDialog：FBSDKAppInviteDialog !, didFailWithError error：NSError！）{
 println（邀请\（错误））
} 
  

I'm trying to implement the protocol FBSDKAppInviteDialogDelegate on my class but the xcode show me a erro that says "Type MyClass does not conform to protocol 'FBSDKAppInviteDialogDelegate'"

Definition of protocol:

@protocol FBSDKAppInviteDialogDelegate <NSObject>

/*!
@abstract Sent to the delegate when the app invite completes without error.
@param appInviteDialog The FBSDKAppInviteDialog that completed.
@param results The results from the dialog.  This may be nil or empty.
*/
- (void)appInviteDialog:(FBSDKAppInviteDialog *)appInviteDialog didCompleteWithResults:(NSDictionary *)results;

/*!
@abstract Sent to the delegate when the app invite encounters an error.
@param appInviteDialog The FBSDKAppInviteDialog that completed.
@param error The error.
*/
- (void)appInviteDialog:(FBSDKAppInviteDialog *)appInviteDialog didFailWithError:(NSError *)error;

@end

My code:

The definition of my class

class MyClasse: UITableViewController, FBSDKAppInviteDialogDelegate

To call the invite dialog:

var inviteDialog:FBSDKAppInviteDialog = FBSDKAppInviteDialog()
if(inviteDialog.canShow()){
    let appLinkUrl:NSURL = NSURL(string: "http://mylink.com")!
    let previewImageUrl:NSURL = NSURL(string: "http://mylink.com/image.png")!

    var inviteContent:FBSDKAppInviteContent = FBSDKAppInviteContent(appLinkURL: appLinkUrl)
    inviteContent.previewImageURL = previewImageUrl

    inviteDialog.content = inviteContent
    inviteDialog.delegate = self
    inviteDialog.show()
}

The implementation of procol methods:

//function of FBSDKAppInviteDialogDelegate
func appInviteDialog(appInviteDialog: FBSDKAppInviteDialog!, didCompleteWithResults results: NSDictionary!){
    // my code here
}
//function of FBSDKAppInviteDialogDelegate
func appInviteDialog(appInviteDialog: FBSDKAppInviteDialog!, didFailWithError error: NSError!){
    // my code here
}

The invitation dialog works. But without the protocol i cant get the results.

What i'm missing here?

解决方案

The issue is with NSDictionary. The following is working for me:

func appInviteDialog(appInviteDialog: FBSDKAppInviteDialog!, didCompleteWithResults results: [NSObject : AnyObject]!) {
    println("Complete invite without error")
}

func appInviteDialog(appInviteDialog: FBSDKAppInviteDialog!, didFailWithError error: NSError!) {
    println("Error in invite \(error)")
}
