UIAlertView UITextField showing black border - ios

Question

I am creating UIAlertView with textinput, but though I clear the background and giving border colour its showing a black border.
UIAlertView *alerttorename=[[UIAlertView alloc]initWithTitle:#"Dropbox Export" message:#"Export As:" delegate:projectDetailsReference cancelButtonTitle:nil otherButtonTitles:#"OK", nil];
alerttorename.alertViewStyle = UIAlertViewStylePlainTextInput;
[[alerttorename textFieldAtIndex:0] setText:[appDelegate.projectName stringByDeletingPathExtension]];
UITextField *textField = [alerttorename textFieldAtIndex:0];
[textField setBackgroundColor:[UIColor clearColor]];
textField.borderStyle=UITextBorderStyleRoundedRect ;
textField.layer.borderColor=[[UIColor lightGrayColor]CGColor];
textField.layer.borderWidth = 0.1f;
textField.layer.cornerRadius = 5;
textField.clipsToBounds = YES;
alerttorename.tag=233;
[alerttorename show];

Refer this example, UIAlertController :
UIAlertController *alertController = [UIAlertController
alertControllerWithTitle:alertTitle
message:alertMessage
preferredStyle:UIAlertControllerStyleAlert];
[alertController addTextFieldWithConfigurationHandler:^(UITextField *textField)
{
textField.placeholder = NSLocalizedString(#"LoginPlaceholder", #"Login");
}];
[alertController addTextFieldWithConfigurationHandler:^(UITextField *textField)
{
textField.placeholder = NSLocalizedString(#"PasswordPlaceholder", #"Password");
textField.secureTextEntry = YES;
}];
The values of the text field can be retrieved in the OK action handler:
UIAlertAction *okAction = [UIAlertAction
actionWithTitle:NSLocalizedString(#"OK", #"OK action")
style:UIAlertActionStyleDefault
handler:^(UIAlertAction *action)
{
UITextField *login = alertController.textFields.firstObject;
UITextField *password = alertController.textFields.lastObject;
}];

Use this category for UIView to display alertView in iOS > 7.0 . Here you don't need to worry about UIAlertView or UIAlertViewController.
#define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
#interface UIView (AlertView)
+( void )showSimpleAlertWithTitle:( NSString * )title
message:( NSString * )message
cancelButtonTitle:( NSString * )cancelButtonTitle;
#end
#interface UIView (AlertView)
+( void )showSimpleAlertWithTitle:( NSString * )title
message:( NSString * )message
cancelButtonTitle:( NSString * )cancelButtonTitle
{
if(SYSTEM_VERSION_LESS_THAN(#"8"))
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle: title
message: message
delegate: nil
cancelButtonTitle: cancelButtonTitle
otherButtonTitles: nil];
[alert show];
}
else
{
// nil titles break alert interface on iOS 8.0, so we'll be using empty strings
UIAlertController *alert = [UIAlertController alertControllerWithTitle: title == nil ? #"": title
message: message
preferredStyle: UIAlertControllerStyleAlert];
UIAlertAction *defaultAction = [UIAlertAction actionWithTitle: cancelButtonTitle
style: UIAlertActionStyleDefault
handler: nil];
[alert addAction: defaultAction];
UIViewController *rootViewController = [UIApplication sharedApplication].keyWindow.rootViewController;
[rootViewController presentViewController: alert animated: YES completion: nil];
}
}
#end
Usage of this category like this:
[UIView showSimpleAlertWithTitle:#"Title here" message:#"Message here" cancelButtonTitle:#"Ok"];
