IOS UIWebView Usage

First create the UIWebView, this is not difficult, set the frame, and then add to the Self.view:

UIWebView *webView = [[UIWebView alloc] initWithFrame:self.view.bounds];webView.scalesPageToFit = YES;//自动对页面进行缩放以适应屏幕[self.view addSubview:webView];

UIWebView Load Network Address

UIWebView to load the network address, that my blog: http://blog.csdn.net/dylan_lwb_ for example. The code is as follows:

NSURLRequest *request =[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://blog.csdn.net/dylan_lwb_"]];[self.view addSubview:webView];[webView loadRequest:request];

UIWebView loading local resources via Nsurlrequest

NSString *path = [[NSBundle mainBundle] pathForResource:@"swift" ofType:@"html"];NSURL* url = [NSURL   fileURLWithPath:path];//创建URLNSURLRequest* request = [NSURLRequest requestWithURL:url];//创建NSURLRequest[webView loadRequest:request];//加载

Load via NSString

uiwebview also supports loading a NSString object as a source. You can provide it with a base URL to instruct the UIWebView object how to follow the link and load the remote resource:

NSString *path = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"];NSString *htmlString = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];[webView loadHTMLString:htmlString baseURL:[NSURL URLWithString:path]];

Automatic phone detection

Set this property, if you encounter a phone number in the loaded Web page, you can dial it directly by clicking it, it is very convenient:

webView.dataDetectorTypes = UIDataDetectorTypePhoneNumber;//自动检测网页上的电话号码，单击可以拨打

Set Proxy and Proxy methods

uiwebview has five proxy methods, we can complete different requirements in different proxy methods.

//设置代理webView.delegate = self;//代理方法- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType{ //返回YES，进行加载。通过UIWebViewNavigationType可以得到请求发起的原因 return YES;}- (void)webViewDidStartLoad:(UIWebView *)webView{ //开始加载，可以加上风火轮（也叫菊花）}- (void)webViewDidFinishLoad:(UIWebView *)webView{ //完成加载}- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error{ //加载出错}

Create load him, stop, rewind, forward button

Create four buttons, namely Load button, stop button, Back button, Forward button:

nsarray *array = [Nsarray arraywithobjects:@" Load "@" Stop "@" back " , @ "forward", nil]; int far = (screen.width-200)/5; for (int i = 0; i < Array.count; i++) {UIButton *button = [[UIButton alloc] init]; Button.frame = CGRectMake ((i + 1) * far + * I, screen.height-60, 50, 40); Button.tag = + i; [Button addtarget:self action: @selector (Actionclick:) forcontrolevents:uicontroleventtouchupinside]; [Button Settitlecolor:[uicolor Bluecolor] forstate:uicontrolstatenormal]; [Button Setbackgroundcolor:[uicolor Orangecolor]; [Button settitle:array[i] forstate:uicontrolstatenormal]; [Self.view Addsubview:button]; }

Forward and backward

To bind events to four buttons, distinguish each click event according to the tag value:

- (void)actionClick:(UIButton *)button{ switch (button.tag) { case 200: { [self.webView reload];//加载 } break; case 201: { [self.webView stopLoading];//停止加载 } break; case 202: { [self.webView goBack];//返回 } break; case 203: { [self.webView goForward];//前进 } break; default: break; }}
