似乎有时当我使用AFHTTPRequestOperation Manager调用包含GET请求的某些方法时，它有时会使用操作管理器不正确地从另一个GET请求中回调到另一个成功的块/闭包。
根据错误日志，它似乎与闭包中的解包选项有关，这似乎是一个关于Swift和Objective C兼容性的讨论问题，但我不确定如何必须解决这个问题我特定的代码集。
我也不想使用Alamo Fire Swift库，我宁愿坚持使用AFNetworking Cocoapod，因为该库的作者说两者都应该可以在Swift项目中使用。
这是我得到的错误日志。

此处的成功模块是AppDelegate：615
let manager = AFHTTPRequestOperationManager()
var user_id : Int = NSUserDefaults.standardUserDefaults().objectForKey("user_id") as Int
if (justSeenEventIDs.count > 0){
manager.GET(serverURL+"users/seen_events.json",
parameters: ["user_id" : userID()!, "event_ids" : justSeenEventIDs],
success: { (operation: AFHTTPRequestOperation!,responseObject: AnyObject!) -> Void in
println("JSON: " + responseObject.description)
if (responseObject.isKindOfClass(NSDictionary)){
}
},
failure: { (operation: AFHTTPRequestOperation!,error: NSError!) -> Void in
println("Error: " + error.localizedDescription + " code: " + "\(error.code)")
})
}
此函数中成功块的开头是GroupsDataSource：365
func loadGroups(completion:(dictionary : NSDictionary?) -> Void){
let manager = AFHTTPRequestOperationManager()
manager.requestSerializer = AFJSONRequestSerializer() as AFJSONRequestSerializer
manager.GET(serverURL+"users/get_state.json",
parameters: ["user_id" : userID()!],
success: { (operation: AFHTTPRequestOperation!,responseObject: AnyObject!) -> Void in
println("JSON: " + responseObject.description)
if (responseObject.isKindOfClass(NSDictionary)){
var dict : NSDictionary = responseObject as NSDictionary
if (dict.objectForKey("groups") != nil){
self.parseDataFromStateDictionary(responseObject as NSDictionary)
// self.parseDataFromGroupsDictionary(responseObject as NSDictionary)
}
else{
completion(dictionary: responseObject as? NSDictionary)
}
}else if(responseObject.isKindOfClass(NSArray)){
}
completion(dictionary: nil)
},
failure: { (operation: AFHTTPRequestOperation!,error: NSError!) -> Void in
println("Error: " + error.localizedDescription + " code: " + "\(error.code)")
completion(dictionary: nil)
})
}
最后一个闭包：GroupsDataSource：809。你看到很多CLSNSLogv的原因是因为这个错误似乎只发生在内部分发（生产），而不是通过闪电电缆直接建立设备。如果这有帮助，则仅调用CLSNSLogv 4,5和6，而不是3。
