UIWebView的使用---safri

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 ()<UIWebViewDelegate>
@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;
}

上面放上的webview，下面就是toolBar
