例項方法
例項方法是在例項化例項後,在類的特定例項上可用的方法:
MyClass *instance = [MyClass new];
[instance someInstanceMethod];
這是你如何定義一個:
@interface MyClass : NSObject
- (void)someInstanceMethod; // "-" denotes an instance method
@end
@implementation MyClass
- (void)someInstanceMethod {
NSLog(@"Whose idea was it to have a method called \"someInstanceMethod\"?");
}
@end
