iphone - @property @synthesize

Question

@synthesize 和 @property 在 Xcode 中做什么？请用非常简单的术语进行解释？

Answer 1

您要求简单的术语:

@property declares a property in your class header

@property (nonatomic, retain) NSString *myString;

@synthesize creates your setter and getter for your property (accessor methods)

Without synthesize you have to write your own setter and getter implemention, like getMyString or setMyString (capitalize the first character of your property)
