The only places where you can access the property’s backing instance variable directly is in the init and dealloc methods for your class and when you provide a custom getter and setter. propertyName. propertyName”. Tip: With the latest versions of Xcode you’re no longer required to manually synthesize your properties. You can completely leave out the @synthesize statement and the compiler will automatically create the backing instance variable for you. The name of this variable is the same as the property name, but again with an additional underscore in front.
We use it to make sure any spaces or other characters in the search text that the user types get converted to something that is valid for use in an HTTP GET request. The compiler gives several errors: • ARC Casting Rules: Cast of C pointer type 'CFStringRef' (aka 'const struct __CFString *') to Objective-C pointer type 'NSString *' requires a bridged cast • Semantic Issue: 'autorelease' is unavailable: not available in automatic reference counting mode • ARC Restrictions: ARC forbids explicit message send of 'autorelease' The last two errors are really the same and simply mean that you cannot call [autorelease].
To summarize: • When changing ownership from Core Foundation to Objective-C you use CFBridgingRelease() or __bridge_transfer. • When changing ownership from Objective-C to Core Foundation you use CFBridgingRetain() or __bridge_retained. • When you want to use one type temporarily as if it were another without ownership change, you use __bridge. That’s it as far as MainViewController is concerned. All the errors should be gone now and you can build and run the app. The conversion of the Artists app to ARC is complete!
