iOS7 UIWebView Memory leak

Question

We have an comprehensive iOS app with Hybrid mode - a UIWebView hold the major part of the web application in JS. It works fine on iOS6, but recently we found serious out of mem

Answer 1

Both the UIWebView and the native safari browser with iOS7 seems to have a problem in memory management when handling json object. If you have a dictionary with a deep nested structure, and you happen to have one of the key to be a numeric string, and it is less than 99999, you might have received memory warnings frequently.

something like,

 {"**98304**":
     {"key":
         {"2ndLevelKey":
             {
                "address":"10928 Homestead rd","city":"Cupertino","Zip":95014
             }
         }
     }
 }

The work around is simple, try to replace the key "98304" something like "ID98304". Hope you have tackled the problem already. :)
