i have an application in which when the user enters his username and password in the login form , his username and password are submitted to the server database for validation and if he is a valid user a tokenid is generated for him through JSON response and he is allowed to log in.this is the JSON response that i get in the console when a valid user log in through the log in form :

{"TokenID":"kaenn43otO","isError":false,"ErrorMessage":"","Result":[{"UserId":"164","FirstName":"Indu","LastName":"nair","Email":"[email protected]","ProfileImage":null,"ThumbnailImage":null,"DeviceInfoId":"22"}],"ErrorCode":900}
2011-06-24 11:56:57.639 Journey[5526:207] this is token id:kaenn43otO

so when the same user wants to update his profile by clicking on the update tab using the tokenid So that if he want he can his firstname,lastname,password,email.etc.i

i have done   the following code to update  the user profile using tokenid but it does not work.i get tokenid when the user log in and this tokenid i have to pass to other class:
this is my code to update user profile: 


-(void)sendRequest

for a particular user who logs in only his profile must be update by using tokenid and userid.Please help me in solving this problem.Thanks
