1.将WKWebView的WKUIDelegate设置成self。
2.将一下三个方法拷贝到项目中。
- 解决alert方法
-(void)webView:(WKWebView *)webView runJavaScriptAlertPanelWithMessage:(NSString *)message initiatedByFrame:(WKFrameInfo *)frame completionHandler:(void (^)(void))completionHandler{
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:nil message:message?:@"" preferredStyle:UIAlertControllerStyleAlert];
[alertController addAction:([UIAlertAction actionWithTitle:@"确认" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
completionHandler();
}])];
[self presentViewController:alertController animated:YES completion:nil];
}
- 解决confirm
- (void)webView:(WKWebView *)webView runJavaScriptTextInputPanelWithPrompt:(NSString *)prompt defaultText:(NSString *)defaultText initiatedByFrame:(WKFrameInfo *)frame completionHandler:(void (^)(NSString * _Nullable))completionHandler{
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:prompt message:@"" preferredStyle:UIAlertControllerStyleAlert];
[alertController addTextFieldWithConfigurationHandler:^(UITextField * _Nonnull textField) {
textField.text = defaultText;
}];
[alertController addAction:([UIAlertAction actionWithTitle:@"完成" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
completionHandler(alertController.textFields[0].text?:@"");
}])];
[self presentViewController:alertController animated:YES completion:nil];
}
- 解决prompt
- (void)webView:(WKWebView )webView runJavaScriptTextInputPanelWithPrompt:(NSString )prompt defaultText:(NSString )defaultText initiatedByFrame:(WKFrameInfo )frame completionHandler:(void (^)(NSString _Nullable))completionHandler{
UIAlertController alertController = [UIAlertController alertControllerWithTitle:prompt message:@"" preferredStyle:UIAlertControllerStyleAlert];
[alertController addTextFieldWithConfigurationHandler:^(UITextField _Nonnull textField) {
textField.text = defaultText;
}];
[alertController addAction:([UIAlertAction actionWithTitle:@"完成" style:UIAlertActionStyleDefault handler:^(UIAlertAction _Nonnull action) {br/>completionHandler(alertController.textFields[0].text?:@"");
}])];
[self presentViewController:alertController animated:YES completion:nil];
}
