Unfortunately, from "available features" perspective, XCode
is a very old IDE. Therefore no foldable code regions - see detailed discussion Xcode regions
Also note that with the latest compiler (LLVM 4.0), declaring @synthesize
is optional. You can enable/disable it in compiler settings in your project settings.
However, if you are using GCC or an older LLVM version (for whatever reasons), this is not possible.
Edit: After rereading your question... having 50 properties in one class smells very bad. Consider splitting your class into several smaller classes.
You can also put the @synthesize
commands to the end of the @implementation
file.
