单击UIWebView上的链接时打开新的UIViewController [英] Opening a new UIViewController when a link on a UIWebView is clicked

问题描述

我发现这个帖子符合我的问题：单击UIWebView中的链接会推送到NavigationView堆栈

I found this thread which matches my problem: Clicking a link in UIWebView pushes onto the NavigationView stack

但是，以下情况有所不同：
我使用的不是导航控制器，而是使用一个基于视图的应用程序，当按下相应的按钮时手动切换到不同的viewcontroller。
而不是使用链接我使用onClick方法来检测用户何时点击UIWebView上的某些内容并尝试使用新的UIWebView打开新的ViewController。

However, the following situations are different: Instead of using a navigationController, I am using a View Based application to manually switch to different viewcontroller when corresponding buttons are pressed. Rather than using links I am using onClick method to detect when a user clicks on something on a UIWebView and trying to open a new ViewController with a new UIWebView.

相同的代码是否有效或是否需要进行一些更改？

Will the same code work or do i have to make some changes?

推荐答案

您将需要做一些修改

1st：
当 onClick 时，您必须将当前页面重定向到新位置
例如，这个位置将是 MYLocation：// GoThere

1st: when onClick, you will have to redirect your current page to a new location This location for example will be MYLocation://GoThere

第二名：
更新 shouldStartLoadWithRequest

-(BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType {

NSURL *url = request.URL;
NSString *urlString = url.absoluteString;

//Check if special link
if ( [ urlString isEqualToString: @"MYLocation://GoThere" ] ) {
    //Here present the new view controller
    MyViewController *controller = [[MyViewController alloc] init];
    [self presentViewController:controller animated:YES];

    return NO;
}

    return YES;

}
