问题
I created a @property by right-clicking and dragging from ViewController.xib into ViewController.h, but @synthesize is not being automatically created in ViewController.m.
This post said that @synthesize is no longer necessary, but I'm wondering if auto-complete needs @synthesize for it to work correctly.
Q: Do I need to include @synthesize?
回答1:
In a word, no. Xcode 4.5 is fully aware of the fact that @synthesize is no longer required. You're good to go without!
回答2:
When using ARC @synthesize auto appears. outside ARC you have to add it. Adrian

Yes, you are good to go but make sure you specify it like this: self.textInput.text=@"Hello world" Without the self it is not recognized.
