    1.隐藏上下滚动时出边界的后面的黑色的阴影

    - (void) hideGradientBackground:(UIView*)theView

    {

    for (UIView * subview in theView.subviews)

    {

    if ([subview isKindOfClass:[UIImageView class]])

    subview.hidden = YES;

    [self hideGradientBackground:subview];

    }

    }

    2. 禁用拖拽时的反弹效果

    [(UIScrollView *)[[webView subviews] objectAtIndex:0] setBounces:NO];

    3. 通过navigationType判断用户点击类型

    - (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType

    {

    switch (navigationType)

    {

    //点击连接

    case UIWebViewNavigationTypeLinkClicked:

    {

    NSLog(@"clicked");

    }

    break;

    //提交表单

    case UIWebViewNavigationTypeFormSubmitted:

    {

    NSLog(@"submitted");

    }

    //点击返回按钮

    case UIWebViewNavigationTypeBackForward

    {

    NSLog(@"back");

    }

    //点击重新加载按钮

    case UIWebViewNavigationTypeReload

    {

    NSLog(@"reload");

    }

    //表单重新提交

    case UIWebViewNavigationTypeFormResubmitted

    {

    NSLog(@"formResubmitted");

    }

    default:

    break;

    }

    return YES;

    }

    #import "BaseViewController.h"

    @interface BaseViewController ()

    {

    UIWebView *webview;

    }

    @end

    @implementation BaseViewController

    #pragma  mark -life cicry

    - (void)viewDidLoad

    {

    [super viewDidLoad];

    webview=[[UIWebView alloc] initWithFrame:self.view.bounds];

    webview.delegate=self;//因为这个代理设置的self

    [self.view addSubview:webview];

    [webview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:self.requestUrl]]];

    [webview release];

    UIScrollView *scollview=(UIScrollView *)[[webview subviews]objectAtIndex:0];

    scollview.bounces=NO;

    // Do any additional setup after loading the view.

    }

    - (void)didReceiveMemoryWarning

    {

    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.

    }

    -(void)viewDidUnload{

    [super viewDidUnload];

    self.requestUrl=nil;

    }

    - (void)dealloc

    {

    [_requestUrl release];

    [super dealloc];

    }
