第一步:新建一个Single View工程:
第二步:新建好工程,关闭arc。
第三步:拖放一个Text Field 一个UIButton 和一个 UIWebView . Text Field 的title 属性设置为 http:// 。UIButton 的title属性设置为 go 。 布局如图:
第四步:为Text Field 和 UIWebView 连线,插座变量分别命名为 textUrl 和 webRequest。为UIButton 连线 .连接一个action事件(- (IBAction)btnGo:(id)sender;)
然后在(- (IBAction)btnGo:(id)sender;里面添加代码:
- (IBAction)btnGo:(id)sender { NSURL* url = [[NSURL alloc] initWithString:textUrl.text]; NSURLRequest* request = [[NSURLRequest alloc] initWithURL:url]; [webRequest loadRequest:request]; [textUrl resignFirstResponder]; [url release]; [request release]; }
到此。一个简单浏览器设计就完成了 。运行如下:输入 http://sina.com.cn
整个项目代码如下:
