Open links in Safari instead of UIWebVIew?
提问by treasure
I have an app with a UIWebViewinside a UIViewController. I load HTML from a web service as a string like this:
我有一个应用程序，UIWebView里面有一个UIViewController. 我从 Web 服务加载 HTML 作为这样的字符串：
self.webView loadHTMLString:_string baseURL:nil
Is it possible for the HTML links in this string to be opened in the browser and not in the UIWebView in my app? How can I do this?
这个字符串中的 HTML 链接是否可以在浏览器中打开，而不是在我的应用程序的 UIWebView 中打开？我怎样才能做到这一点？
I have tried this in the UIViewController that "hosts" the UIWebVIew:
我在“托管” UIWebVIew 的 UIViewController 中尝试过这个：
-(BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
if (navigationType == UIWebViewNavigationTypeLinkClicked) {
[[UIApplication sharedApplication] openURL:[request URL]];
return NO;
}
return YES;
}
It doesn't seem to be working....
它似乎不起作用......
Any ideas?
有任何想法吗？

Have you set the delegate of the UIWebViewto your UIViewController? There's nothing obviously wrong with your code as far as I can see, so it's likely to be something small like that.
您是否将 的代表设置UIWebView为您的UIViewController？就我所见，您的代码没有任何明显错误，所以它可能是这样的小东西。

Add this in class..
在课堂上添加这个..
@interface yourViewController : UIViewController
<UIWebViewDelegate>
Add this in View did load
在视图中添加这个确实加载
- (void)viewDidLoad
{
[description loadHTMLString:string baseURL:nil];
description.delegate = self;
}
Add this in your .m file
将此添加到您的 .m 文件中
-(BOOL) webView:(UIWebView *)inWeb shouldStartLoadWithRequest:(NSURLRequest *)inRequest navigationType:(UIWebViewNavigationType)inType {
if ( inType == UIWebViewNavigationTypeLinkClicked ) {
[[UIApplication sharedApplication] openURL:[inRequest URL]];
return NO;
}
return YES;
}
Note:
笔记：
UIWebView *description;
@synthesize description;
Then It will work perfectly the way you deserve..!! :)
然后它将以您应得的方式完美地工作..！！:)

Set the delegateof the UIWebViewto your UIViewControllerafter that use this UIWebview method and check the condition, for example now webview current url is google.com, if suppose you clicked on gmail the url contains the string with gmail. Use the below method it opened a safari browser and automatically loaded that url.
之后使用此 UIWebview 方法将UIWebView的委托设置为您的UIViewController并检查条件，例如现在 webview 当前 url 是 google.com，如果假设您单击 gmail，则 url 包含带有 gmail 的字符串。使用以下方法打开 safari 浏览器并自动加载该 url。
-(BOOL) webView:(UIWebView *)inWeb shouldStartLoadWithRequest:(NSURLRequest *)inRequest navigationType:(UIWebViewNavigationType)inType {
if ( inType == UIWebViewNavigationTypeLinkClicked ) {
NSURL *url = [inRequest URL];
if ([[url absoluteString] rangeOfString:@"gmail"].location == NSNotFound) {
[[UIApplication sharedApplication] openURL:[inRequest URL]];
return NO;
}
}
return YES;
}

If you already setup properly the UIWebViewDelegate, simply doing
如果您已经正确设置了 UIWebViewDelegate，只需执行
self.webView loadHTMLString:_string baseURL:nil
self.webView.delegate = self;
should work
应该管用

Add this line ( self.webview.delegate = self; )
添加这一行（ self.webview.delegate = self; ）
For Example in viewController.m
例如在 viewController.m
NSString *htmlFile = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"];
NSString* htmlString = [NSString stringWithContentsOfFile:htmlFile encoding:NSUTF8StringEncoding error:nil];
[self.webview loadHTMLString:htmlString baseURL:nil];
self.webview.delegate = self;

Apple introduced a Safari View Controller on iOS 9. Safari View Controller brings all of the features user expect from Safari over to your app without ever leaving it.
Apple 在 iOS 9 上引入了 Safari View Controller。Safari View Controller 将用户期望从 Safari 获得的所有功能带到您的应用程序中，而无需离开它。
First we need to import Safari Services
首先我们需要导入Safari服务
#import <SafariServices/SafariServices.h>
For Objective C:-
对于目标 C：-
NSString *yourUrl = @"http://yourURL";
SFSafariViewController *svc= [[SFSafariViewController alloc] initWithURL:[NSURL URLWithString: yourUrl]];
[self presentViewController:svc animated:YES completion:nil];
For Swift:-
对于斯威夫特：-
let svc = SFSafariViewController(URL: NSURL(string: self.urlString)!)
self.presentViewController(svc, animated: true, completion: nil)
