[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSURL *url = [NSURL URLWithString:@"https://www.baidu.com"];
NSLog(@"url的scheme为：%@",[url scheme]);
NSLog(@"url的host%@",[url host]);
NSLog(@"url的port%@",[url port]);
NSLog(@"url的path为%@",[url path]);
//使用URL对应的资源初始化NSString
NSString *baidu = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil];//输出NSString 即可看到页面的源代码
NSLog(@"%@",baidu);
}

[super didReceiveMemoryWarning];
