Question

I intend to convert the NSDictionary* object in iOS SDK to NSString*.

Lets say my NSDictionary object has following key value pairs:
{“aps”:{“badge”:9, “alert”:”hello”}} (notice that value itself is a NSDictionary object)
and I want it to convert into a hash map with key value pair as {“aps”:”badge:9, alert:hello”} (notice value is just a string).

I am able to print the value in NsDictionary using the following code:

NSDictionary *userInfo; //it is passed as an argument and contains the string I mentioned above
for (id key in userInfo)
{
     NSString* value = [userInfo valueForKey:key]; 
     funct( [value UTF9String]; // my function 
}

But i am not able to call any NSString method on value object like UTT8String. It gives me error “Terminating app due to uncaught exception NSInvalidArgumentException: reason [_NSCFDictionary UTF8String]: unrecognised selector sent to instance

I found the easiest way out. calling the description method on the NSDictionary object gives me what I needed exactly. Stupid to have missed it on first go.
