一、使用官方safri导入#import <SafariServices/SafariServices.h>

//可以当webView来使用，里面的逻辑都不需要自己去实现 SFSafariViewController *view = [[SFSafariViewController alloc] initWithURL:[NSURL URLWithString:url]];  UITabBarController *tabTar = (UITabBarController *)self.window.rootViewController;    [tabTar.selectedViewController presentViewController:view animated:YES completion:nil];

 二、自己添加个web控制器和下面添加toolBar(上面放的是toolBarItem)

@interface BSWebViewController ()
     
      @property (weak, nonatomic) IBOutlet UIWebView *webView;@property (weak, nonatomic) IBOutlet UIBarButtonItem *faword;@property (weak, nonatomic) IBOutlet UIBarButtonItem *goBack;@end@implementation BSWebViewController- (void)viewDidLoad {    [super viewDidLoad];    [self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:self.url]]];    self.webView.delegate = self;}- (IBAction)forward:(UIBarButtonItem *)sender {    [self.webView goForward];}- (IBAction)goBack:(UIBarButtonItem *)sender {    [self.webView goBack];}- (void)webViewDidFinishLoad:(UIWebView *)webView{    self.faword.enabled = webView.canGoForward;    self.goBack.enabled = webView.canGoBack;}
     

 h

上面放上的webview，下面就是toolBar
