php - iOS JSON Error: NSDebugDescription=Garbage at end

Question

This is a really weird bug, when grabbing JSON from my server (which is produced via PHP), I get this error when calling:

json = [NSJSONSerialization JSONObjectWithData:kivaData
                                       options:kNilOptions
                                         error:&jsonError];

JSON Error: Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (Garbage at end.) UserInfo=0x178467d00 {NSDebugDescription=Garbage at end.}

My (NSData* kivaData) grabs everything perfectly, but it cant parse the JSON.

I have run my JSON code in http://jsonlint.com/ and it comes out Valid everytime.

Its really weird because it can parse the JSON when I connect to Wifi, but when I try doing it via cellular, it wont work. It does work over cellular on some peoples phones, but every time.

encoding is very important. If your json is valid, the issue might be you have special characters in your json data, which is not correctly parsed by the json serializer. When you send the data, make sure you have the correct url-encoding when sending content so client will parse it correctly. Using utf-8 always or base64.
