cast of Objective-C pointer type 'NSString *' to C pointer type 'CFStringRef' (aka 'const struct __CFString *') requires a bridged cast

Question

When converting an Objective-C program to a Objective-C ARC, I get the error:

\"cast of Objective-C pointer type \'NSString *\' to C pointer type \'CFStringR         


        

Answer 1

Here is a nice ARC tutorial that I found to be easier to understand than Apple's documentation that @jtbandes references.

Take a look at the section titled "Toll free bridging" in particular.
