objective-c - 为什么这一段Objectc会报错？
#import <Foundation/Foundation.h>
@interface Person :NSObject
{
int age;
NSString * name;
}
-(void)setAge:(int)age;
-(void) sayHi;
@end
@implementation Person
-(void)setAge:(int)age{
self.age=age;
}
-(void)sayHi{
NSLog(@"im jerry %d",age);
}
@end
int main(int argc, const char * argv[]) {
@autoreleasepool {
Person* p=[Person new];
[p setAge:5];
[p sayHi];
}
return 0;
}
self.age=age;这里报错了。
在java里面，不是this.age=age吗？oc里面难道不行吗？
