IBoutlet，2种不同的书写方式？

Question

I am new to iPhone OS App development. Can somebody explain whats the difference between

IBOutlet UIButton *myButton;


@property (nonatomic, retain) IBOutlet UIButton *myButton; 

As far i understand the first line was used earlier and now we can use the 2nd line. Theres absolutely no need to write both of them. Any idea?

Answer 1

Apple现在建议您仅将IBOutlet声明放在@property 。

Answer 2

I just write IBOutlet in the @property declaration. It won't hurt to put it in both spots though.

You're not asking the difference between the whole lines though are you?
