问题
I could add a textfield in UIAlertController using
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Title" message:@"message" preferredStyle:UIAlertControllerStyleAlert];
[alertController addTextFieldWithConfigurationHandler:^(UITextField * _Nonnull textField) {
}];
Is there any possibility to add a custom textfield inside an alert controller?
回答1:
I do not think that it's possible to use a UITextField subclass in an UIAlertController. You can only edit the textfield's properties in the configuration handler.

No, you can't. You have to implement custom Alert View for this purpose. You can try libraries - ALERT ACTION SHEET LIBRARIES.
Or if you need text field with UIAlertView its self with a 'clean' look - UITextField in UIAlertController (border, backgroundColor)
