IOS---UIWebview用法点滴

1. load from url：

从url加载页面

NSURL *url = [NSURL URLWithString:"http://stackoverflow.com"];

NSString *body = @"laadeedaa";

NSURLRequest *request = [NSURLRequest requestWithURL:url];

[request setHTTPMethod: @"POST"];

// Dump the response to the UIWebView

[webView loadRequest:request];

2. 自定义 webview的请求 ，load with customized request

// Do your POST

NSURL *url = [NSURL URLWithString:"http://stackoverflow.com"];

NSString *body = @"laadeedaa";

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];

[request setHTTPMethod: @"POST"];

[request setHTTPBody: [body dataUsingEncoding:NSUTF8StringEncoding]];

// Dump the response to the UIWebView

[webView loadRequest:request];

3.查看webveiw的返回

// Dump the response to the UIWebView

[webView loadRequest:request];

NSURLResponse *response = nil;

NSError *error = nil;

NSData *respData = [NSURLConnection sendSynchronousRequest:request

returningResponse:&response

error:&error];

NSString *respString = [[[NSString alloc] initWithData:respData

encoding:NSUTF8StringEncoding] autorelease];

NSString *htmlString = [self doSomethingWith:respString];

[webView loadHTMLString:htmlString baseURL:@"http://stackoverflow.com"];

4.通过js控制webview

- (NSString *)stringByEvaluatingJavaScriptFromString:(NSString *)script

例如

：  NSString *html = [yourWebView stringByEvaluatingJavaScriptFromString:

@"document.body.innerHTML"];
