Show keyboard when Textfield inside Alert in WkWebView is tapped - objective-c

Question

There is a game that i load in the WKWebView and this Alert and textField appear after the game is finished. I want to display keyboard when user taps on the textField. But the problem is there is no code to display this alert and textfield, otherwise i would have managed the textField to becomeFirstResponder().
Desperately need some help. I would really appreciate it.

Answer 1

Okay so i have found the solution. I had a textField in custom Alert/Popup in WkwebView and i wanted the textField to becomeFirstResponder() so i could take user input.
// So i Implemented WKUIDelegate..
#import <WebKit/WebKit.h>
#interface MyController : UIViewController<WKUIDelegate>
Assigned the Delegate..
- (void)viewDidLoad {
[super viewDidLoad];
_webkitView.UIDelegate = self;
}
//implemented delegate function.
- (void)webView:(WKWebView *)webView runJavaScriptTextInputPanelWithPrompt:(NSString *)prompt defaultText:(NSString *)defaultText initiatedByFrame:(WKFrameInfo *)frame completionHandler:(void (^)(NSString *result))completionHandler
{
UIAlertController *alert = [UIAlertController alertControllerWithTitle:#"BlockChaid Id, Email or Username"
message:prompt
preferredStyle:UIAlertControllerStyleAlert];
[alert addTextFieldWithConfigurationHandler:^(UITextField *textField) {
textField.placeholder = prompt;
textField.secureTextEntry = NO;
textField.text = defaultText;
}];
[alert addAction:[UIAlertAction actionWithTitle:NSLocalizedString(#"Cancel", nil) style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {
completionHandler(nil);
}]];
[alert addAction:[UIAlertAction actionWithTitle:NSLocalizedString(#"OK", nil) style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
completionHandler([alert.textFields.firstObject text]);
}]];
[self presentViewController:alert animated:YES completion:nil];
}
After successful build, this was the output.
I tapped the textField, and javaScript Alert appeared.
This right here is what i wanted to achieve.
Maybe i was not good enough to explain my question, but this is what i was asking for. Thank you :)
