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:

//  webTest

#import <UIKit/UIKit.h>

@interface wsqViewController : UIViewController {
    UITextField *textUrl;
    UIWebView *webRequest;
}

@property (retain, nonatomic) IBOutlet UITextField *textUrl;

@property (retain, nonatomic) IBOutlet UIWebView *webRequest;
- (IBAction)btnGo:(id)sender;
@end

#import "wsqViewController.h"

@implementation wsqViewController
@synthesize textUrl;
@synthesize webRequest;

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
   
}

#pragma mark - View lifecycle

- (void)viewDidLoad
{
    [super viewDidLoad];
    
}

- (void)viewDidUnload
{
    [self setTextUrl:nil];
    [self setWebRequest:nil];
    [super viewDidUnload];
    
}

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
}

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
}

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
}

- (void)viewDidDisappear:(BOOL)animated
{
    [super viewDidDisappear:animated];
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}

- (void)dealloc {
    [textUrl release];
    [webRequest release];
    [super dealloc];
}
- (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];
}
@end
