如何通过点击提交获得提醒?
我正在使用WebView ..
这是代码
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
[webView setDelegate:self];
NSString *urlAddress = @“sssssss”;
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];
[self.view addSubview:webView];
先谢谢..

检查一下:
- (BOOL)webView: (UIWebView*)webView shouldStartLoadWithRequest: (NSURLRequest*)request navigationType: (UIWebViewNavigationType)navigationType {
NSString *fragment, *scheme;
if (navigationType == UIWebViewNavigationTypeLinkClicked) {
//1
[webView stopLoading];
fragment = [[request URL] fragment];
scheme = [[request URL] scheme];
if ([scheme isEqualToString: @"file"] && [self respondsToSelector: NSSelectorFromString(fragment)]) {
[self performSelector: NSSelectorFromString(fragment)];
return NO;
}
[[UIApplication sharedApplication] openURL: [request URL]];
}
return YES;
}
您需要将委托设置为WebView。
希望这有帮助。

1 - 在提交按钮中添加IBAction。
2 - 在被调用的方法内部使用UIAlertController创建一个警告,该警告将在单击按钮时显示。
