-(void)pushBtnCellClickDeleate{
    NSLog(@"跳转");
    
    //在APP内部打开指定网页
    UIWebView *myWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height)];
    NSURL *url = [NSURL URLWithString:@"https://www.baidu.com/"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [myWebView loadRequest:request];
    [self.view addSubview:myWebView];
    
    
    //在APP外部浏览器中打开指定网页（一般默认跳转苹果自带Safari浏览器）
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://www.baidu.com/"]];
