UIWebView的簡單使用

在項目中有時需要加載h5，這就用到了webview

1.利用webView可加載服務器h5和本地h5

 2.設置代理並遵守協議

首先需要在plist裏做一下設置

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSAllowsArbitraryLoads</key>
  <true/>
</dict>

1.加載本地h5

UIWebView *webView = [[UIWebView alloc]initWithFrame:self.view.bounds]; 

webView.dataDetectorTypes = UIDataDetectorTypeAll; //識別webview中的類型，例如 當webview中有電話號碼，點擊號碼就能直接打電話

webView.scrollView.scrollEnabled = NO;//禁止滑動

NSURL *url = [[NSBundle mainBundle]URLForResource:@"index" withExtension:@"html"];

或NSURL *url = [[NSBundle mainBundle] URLForResource:@"index.html"withExtension:nil];

NSURLRequest *request = [NSURLRequestre questWithURL:url];

[webView loadRequest:request];

2.加載網絡上網頁h5

UIWebView *webView = [[UIWebView alloc]initWithFrame:self.view.bounds]; 

webView.dataDetectorTypes = UIDataDetectorTypeAll; //識別webview中的類型，例如 當webview中有電話號碼，點擊號碼就能直接打電話

webView.scrollView.scrollEnabled = NO;//禁止滑動

NSURL *url = [NSURL URLWithString:@"http://www.baidu.com"];

NSURLRequest *request = [NSURLRequestre questWithURL:url];

[webView loadRequest:request];

3．調用的代理方法

//準備加載內容時調用，通過返回值來判斷是否設置加載

- (BOOL)webView:(UIWebView *)webViewshouldStartLoadWithRequest:(NSURLRequest *)requestnavigationType:(UIWebViewNavigationType)navigationType;

//開始加載時調用

- (void)webViewDidStartLoad:(UIWebView*)webView;

//結束加載時調用

- (void)webViewDidFinishLoad:(UIWebView*)webView;

//加載失敗時調用

- (void)webView:(UIWebView *)webViewdidFailLoadWithError:(NSError *)error;
