使用代碼:可直接粘貼到自己項目中使用
.h

#import "BaseViewController.h"@interface LinkNewsController : BaseViewController/** 新聞連結 */@property (nonatomic, strong) NSString *link;@end

.m

#import #import "MBProgressHUD.h"@interface LinkNewsController (){    //蒙版    MBProgressHUD *_MB;}//網頁視圖@property (nonatomic, strong) WKWebView *WKWebView;@end@implementation LinkNewsController#pragma mark - 懶載入-(WKWebView *)WKWebView{    if (_WKWebView == nil) {        _WKWebView = [[WKWebView alloc] initWithFrame:CGRectMake(0, 64, kScreenWidth, kScreenHeight-64)];        NSLog(@"網頁連結-->link:%@",self.link);        NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:self.link]];        [_WKWebView setNavigationDelegate:self];        [_WKWebView loadRequest:request];    }    return _WKWebView;}#pragma mark - 視圖載入- (void)viewDidLoad {    [super viewDidLoad];    // Do any additional setup after loading the view.    [self.view addSubview:self.WKWebView];}#pragma mark - WKNavigationDelegate//開始載入-(void)webView:(WKWebView *)webView didStartProvisionalNavigation:(WKNavigation *)navigation{    NSLog(@"didStartProvisionalNavigation");    _MB = [MBProgressHUD showHUDAddedTo:self.navigationController.view animated:YES];    [_MB setMode:MBProgressHUDModeIndeterminate];    [_MB setLabelText:@"loading..."];}//載入成功-(void)webView:(WKWebView *)webView didFinishNavigation:(WKNavigation *)navigation{    NSLog(@"didFinishNavigation__");    [MBProgressHUD hideAllHUDsForView:self.navigationController.view animated:YES];}//載入失敗-(void)webView:(WKWebView *)webView didFailNavigation:(WKNavigation *)navigation withError:(NSError *)error{    NSLog(@"");    [MBProgressHUD hideAllHUDsForView:self.navigationController.view animated:YES];}

UIWebView 和 WKWebView 的區別
WKWebView 更快(佔用記憶體可能只有 UIWebView 的1/3~1/4),沒有緩衝,更為細緻地拆分了 UIWebViewDelegate 中的方法。
WKWebView 是輕量級的 UIWebView。
