Swift错误无法转换类型'(AFHTTPRequestOperation ?, AnyObject?)->的值. () [英] Swift error Cannot convert value of type '(AFHTTPRequestOperation?, AnyObject?) -> ()

问题描述

更新xcode版本8.0(8A218a)迅速3后，出现此错误

After I update xcode Version 8.0 (8A218a) swift 3, I got this error

不能将类型'((AFHTTPRequestOperation ?, AnyObject?)->()'的值转换为预期的参数类型'(((AFHTTPRequestOperation ?, Any?)-> Void)！'

Cannot convert value of type '(AFHTTPRequestOperation?, AnyObject?) -> ()' to expected argument type '((AFHTTPRequestOperation?, Any?) -> Void)!'

这是上面显示错误的以下代码.

This is the following code that's shown error above.

jsonmanager.post( "http://myapi.com",
                      parameters: nil,
                      success: { (operation: AFHTTPRequestOperation!,responseObject: AnyObject!) in
                        if(responseObject.object(forKey: "meta")?.object(forKey: "status")?.intValue == 200){....

我做错什么了吗?

在早期版本7.3.1 swift 2中运行良好.

It works well in previous version 7.3.1 swift 2.

推荐答案

回调方法签名已更改.在Swift 2中是

The callback method signature has changed. In Swift 2 it was

(AFHTTPRequestOperation?, AnyObject?) -> Void

在Swift 3中是

(AFHTTPRequestOperation?, Any?) -> Void

您应该更改下面的行

success: { (operation: AFHTTPRequestOperation!,responseObject: AnyObject!)

收件人

success: { (operation: AFHTTPRequestOperation?, responseObject: Any?)
