I have updated swift 3 and I found many errors. This is one of them :
Value of type 'Any?' has no member 'object'
This is my code :
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()
}
New Error Update :
Optional chain has no effect, expression already produces 'Any?'
And
Cannot call value of non-function type 'Any?!'
It works well in previous version 7.3.1 swift 2.
This is json response :
{
"meta":{"status":200,"msg":"OK"},
"response":[""],
"total_data":0
}
Unlike Swift 2, Swift 3 imports Objective-C's id
as Any?
instead of AnyObject?
(see this Swift evolution proposal). To fix your error, you need to cast all of your variables to AnyObject
. This may look something like the following:
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()
}
}
您的responseObject
是Optional
(具体来说,是Any?
),因此您必须将其拆开以调用其方法或访问其属性,例如responseObject?.object(forKey: "meta")
等等。现在,那些以前是非Optional
值的框架现在是Optional
,尤其是在没有指定可空性限定符的情况下在Objective-C中使用它们的情况。
