从 UIWeb 视图打开 Mobile Safari

Question

我知道这是一个已经讨论过的主题，我尝试了此处发布的所有解决方案，但没有成功。我有一个 UIWebView，它显示本地文件，我想在 Safari 中打开 Web 链接（以 http:// 开头），而不是在视图内。
这是我的“小”应用程序的代码： onceViewController.h

#import <UIKit/UIKit.h>

@interface onceViewController : UIViewController <UIWebViewDelegate>{
    IBOutlet UIWebView *slampSite;
}

@property (retain, nonatomic) UIWebView *slampSite;

@end

onceViewController.m

#import "onceViewController.h"

@implementation onceViewController

@synthesize slampSite;

#define WWW_ROOT    @"files/en"

- (void)viewDidLoad {
    [super viewDidLoad];
    NSString *path = [[NSBundle mainBundle] pathForResource:@"home" ofType:@"html" inDirectory:WWW_ROOT];
    NSURL *url = [NSURL fileURLWithPath:path];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [slampSite loadRequest:request];
}

- (BOOL)webView:(UIWebView *)slampSite shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType;
{  
    NSURL *requestURL = [ [ request URL ] retain ];  
    if ( ( [ [ requestURL scheme ] isEqualToString: @"http" ]  
          || [ [ requestURL scheme ] isEqualToString: @"https" ] )  
        && ( navigationType == UIWebViewNavigationTypeLinkClicked ) ) {  
        return ![ [ UIApplication sharedApplication ] openURL: [ requestURL autorelease ] ];  
    }  
    [ requestURL release ];
    return YES;  
} 
[omissis]

- (void)dealloc {
    [slampSite release];
    [super dealloc];
}

@end

我缺少什么？

谢谢你！

您需要实现 webview delegate 的 webView:shouldStartLoadWithRequest:navigationType: 方法。当 navigationType 为 UIWebViewNavigationTypeLinkClicked 时，如有必要，请检查 request.URL，并使用 [[UIApplication sharedApplication] openURL:request.URL] 在 Safari 中打开它代码>.
