Ios 快速实施FBSDKAppInviteDialogDelegate不起作用
我试图在我的类上实现协议FBSDKAppInviteDialogDelegate,但是xcode向我显示了一个错误,它说“类型MyClass不符合协议‘FBSDKAppInviteDialogDelegate’” 议定书的定义:Ios 快速实施FBSDKAppInviteDialogDelegate不起作用,ios,facebook,swift,facebook-ios-sdk,Ios,Facebook,Swift,Facebook Ios Sdk,我试图在我的类上实现协议FBSDKAppInviteDialogDelegate,但是xcode向我显示了一个错误,它说“类型MyClass不符合协议‘FBSDKAppInviteDialogDelegate’” 议定书的定义: @protocol FBSDKAppInviteDialogDelegate <NSObject> /*! @abstract Sent to the delegate when the app invite completes without error

要调用邀请对话框,请执行以下操作:
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方法的实施:
//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
}
“邀请”对话框起作用。但是如果没有协议,我就不能得到结果
我在这里遗漏了什么?问题在于NSDictionary。以下内容适用于我:
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)")
}
看起来很像。我认为这与你的协议方法的签名有关。
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)")
}
