我更新了
swift 3,发现了很多错误.这是其中之一：
Value of type ‘Any?’ has no member ‘object’
这是我的代码：
jsonmanager.post( "http://myapi.com",parameters: nil,success: { (operation: AFHTTPRequestOperation?,responSEObject: Any?) in
if(((responSEObject? as AnyObject).object(forKey: "Meta") as AnyObject).object(forKey: "status")?.intValue == 200 && responSEObject?.object(forKey: "total_data")?.intValue > 0){
let aa: Any? = (responSEObject? as AnyObject).object(forKey: "response")
self.data = (aa as AnyObject).mutableCopy()
}
新错误更新：
Optional chain has no effect,expression already produces ‘Any?’
和
Cannot call value of non-function type ‘Any?!’
它在以前的版本7.3.1 swift 2中运行良好.
这是json的回应：
{
"Meta":{"status":200,"msg":"OK"},"response":[""],"total_data":0
}
解决方法
与Swift 2不同,Swift 3将Objective-C的id导入为Any？而不是AnyObject？ (见
this Swift进化提案).要修复错误,需要将所有变量强制转换为AnyObject.这可能类似于以下内容：
jsonmanager.post("http://myapi.com",parameters: nil) { (operation: AFHTTPRequestOperation?,responSEObject: Any?) in
let response = responSEObject as AnyObject?
let Meta = response?.object(forKey: "Meta") as AnyObject?
let status = Meta?.object(forKey: "status") as AnyObject?
let totalData = response?.object(forKey: "total_data") as AnyObject?
if status?.intValue == 200 && totalData?.intValue != 0 {
let aa = response?.object(forKey: "response") as AnyObject?
self.data = aa?.mutableCopy()
}
}
