Question

I’m using a NSMutable String to gain a string back from a database query. I’ve assigned the variable with @”” and then populate if found from the database. I’ve tried adding autorelease / release but this causes problems with references to the database call.

Can someone point out my error ?

I would have typed this code but I felt the analyzer arrows were useful.

You’re creating an autoreleased NSMutableString and assigning the pointer strDBAAppVer to point to it. But then you throw away the reference to that object, and get the pointer strDBAppVer to point to a new object, an NSString with a retain count of 1.

What I think you want is inside your if statement is something like this:

NSString* databaseField = [[NSString alloc] initWithUTF ...etc.]
[strDBAppVer setString: databaseField];
[databaseField release];
