IOS UIWebView:在safari中打开链接

Question

我创建了自定义类,文件是showBlock.h和showBlock.m,用于以编程方式加载UIWebView,showBlock.m的实现是

#import "showBlock.h"

@implementation showBlock;

@synthesize mainViewContObj;

- (void) showView {
    UIWebView *aWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 50)];
    aWebView.autoresizesSubviews = YES;
    aWebView.autoresizingMask = (UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth);
    [aWebView setDelegate:[self mainViewContObj]];
    NSString *urlAddress = @"http://localhost/test/index.php";
    NSURL *url = [NSURL URLWithString:urlAddress];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];

    [aWebView loadRequest:requestObj];

    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 0, 0)];
    [[[self mainViewContObj] view] addSubview:aWebView];

}
@end

它工作正常,并加载带有html内容的index.php文件,但我想在safari浏览器中打开这个html文件的链接,我需要做些什么呢？

您需要在ShowBlock.m中添加下面的委托方法实现

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request
 navigationType:(UIWebViewNavigationType)navigationType {
    // This practically disables web navigation from the webView.
    if (navigationType == UIWebViewNavigationTypeLinkClicked) {
        [[UIApplication sharedApplication] openURL:[request URL]];
        return FALSE;
    }
    return TRUE;
}
