javascript - UIWebviewからアラートが生成された場所でアラートクリックを処理する方法.?

Question

私もこれを使用しました：

@interface UIWebView (JavaScriptAlert)

 - (void)webView:(UIWebView *)sender runJavaScriptAlertPanelWithMessage:(NSString *)message initiatedByFrame:(WebFrame *)frame;

@end

@implementation UIWebView (JavaScriptAlert)

- (void)webView:(UIWebView *)sender runJavaScriptAlertPanelWithMessage:(NSString *)message initiatedByFrame:(WebFrame *)frame {
    UIAlertView *dialogue = [[UIAlertView alloc] initWithTitle:@"My Alert Title" message:message delegate:self cancelButtonTitle:@"Okay" otherButtonTitles:nil];
    [dialogue show];
}

Answer 1

UIAlertView のデリゲートを使用する必要があります

- (void)webView:(UIWebView *)sender runJavaScriptAlertPanelWithMessage:(NSString *)message initiatedByFrame:(WebFrame *)frame {
    UIAlertView *dialogue = [[UIAlertView alloc] initWithTitle:@"My Alert Title" message:message delegate:self cancelButtonTitle:@"Okay" otherButtonTitles:nil];
    dialogue.tag = 1;
    [dialogue show];
}


-(void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
    if (alertView.tag == 1) {
         if (buttonIndex == alertView.cancelButtonIndex) {
             //Do something here
         }
    }
}
