Objective-C ,ios,iphone开发基础:3分钟教你做一个iphone手机浏览器

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
