UIWebView的高级使用第一回

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];

}
