SFSafariViewController 是 iOS 9.0 出現(xiàn)的
可以不用跳出app直接在app內(nèi)打開(kāi)同Safari相似瀏覽效果的網(wǎng)頁(yè)，其次玩的溜的同學(xué)可以保存數(shù)據(jù)到系統(tǒng)替代UUID等一些功能操作，簡(jiǎn)單使用如下：

#import <SafariServices/SafariServices.h>

<SFSafariViewControllerDelegate>

- (IBAction)action:(id)sender {
    NSURL *url = [NSURL URLWithString:@"https://www.baidu.com"];
    SFSafariViewController *safariVC = [[SFSafariViewController alloc] initWithURL:url];
    safariVC.delegate = self;
    
    
//    self.navigationController.navigationBarHidden = YES;
//    [self.navigationController pushViewController:safariVC animated:YES];
    // 建議
    [self presentViewController:safariVC animated:YES completion:nil];
}

加載完成
- (void)safariViewController:(SFSafariViewController *)controller didCompleteInitialLoad:(BOOL)didLoadSuccessfully {
    
}

點(diǎn)擊左上角的done
- (void)safariViewControllerDidFinish:(SFSafariViewController *)controller {
    
}
