OC-点语法

点语法的本质：方法调用

#import <Foundation/Foundation.h>
#import "Person.h"

int main(int argc, const char * argv[])
{
    Person *p = [Person new];
    
    // 点语法的本质还是方法调用
    p.age = 10; // [p setAge:10];
    
    int a = p.age; // [p age];
    
    
    p.name = @"Jack";
    
    NSString *s = p.name;
    
    NSLog(@"%@", s);
    
    return 0;
}
