WKWebView的简单使用-----内存消耗优于UIWebView

#import "ViewController.h"

//先引入库文件

#import <WebKit/WebKit.h>

@interface ViewController ()

@property (nonatomic, strong) WKWebView *webView;

@end

@implementation ViewController

- (void)viewDidLoad {

    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.

    //创建webView

    self.webView = [[WKWebView alloc] initWithFrame:[UIScreen mainScreen].bounds];

    [self.view addSubview:self.webView];

    //根据URL，在webView上显示内容

    [self requestUrl:@"http://blog.youkuaiyun.com/cf_first"];

}

//具体实现方法

- (void)requestUrl:(NSString *)urlString

{

    NSURL *url = [NSURL URLWithString:urlString];

    NSURLRequest *request = [NSURLRequest requestWithURL:url];

    [self.webView loadRequest:request];

}

- (void)didReceiveMemoryWarning {

    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.

}
