UIAlertView | iOS Code Snippets

Create the alertView with style UIAlertViewStylePlainTextInput:

UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Hello!" message:@"Please enter your name:" delegate:self cancelButtonTitle:@"Continue" otherButtonTitles:nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
UITextField * alertTextField = [alert textFieldAtIndex:0];
alertTextField.keyboardType = UIKeyboardTypeNumberPad;
alertTextField.placeholder = @"Enter your name";
[alert show];

UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Hello!" message:@"Please enter your name:" delegate:self cancelButtonTitle:@"Continue" otherButtonTitles:nil];

alert.alertViewStyle = UIAlertViewStylePlainTextInput;

UITextField * alertTextField = [alert textFieldAtIndex:0];

alertTextField.keyboardType = UIKeyboardTypeNumberPad;

alertTextField.placeholder = @"Enter your name";

[alert show];

This produces an alertView:

UIAlertView that uses the UIAlertViewPlainTextInput alertStyle to ask a user name

When pressing any buttons, the regular delegate methods will be called and you can extract the textInput there like so:

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{ 
    NSLog(@"Entered: %@",[[alertView textFieldAtIndex:0] text]);
}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{

NSLog(@"Entered: %@",[[alertView textFieldAtIndex:0] text]);

}

Declare the UIAlertView delegate in the yourViewController.h:

<UIAlertViewDelegate>

1	<UIAlertViewDelegate>

Create the alertView:

 UIAlertView *alert =
    [[UIAlertView alloc] initWithTitle: @"Here is my alert title."
                               message: @"Here is my alert message."
                              delegate: self
                     cancelButtonTitle: @"Cancel"
                     otherButtonTitles: @"OK", nil];
    [alert show];

UIAlertView *alert =

[[UIAlertView alloc] initWithTitle: @"Here is my alert title."

message: @"Here is my alert message."

delegate: self

cancelButtonTitle: @"Cancel"

otherButtonTitles: @"OK", nil];

[alert show];

Detect which alertView button was tapped:

 if (buttonIndex==0) {
        // button 0 tapped
        NSLog(@"Cancel %d", buttonIndex);

    }else if (buttonIndex==1){
        // button 1 tapped
        NSLog(@"OK %d", buttonIndex);
 }

if (buttonIndex==0) {

// button 0 tapped

NSLog(@"Cancel %d", buttonIndex);

}else if (buttonIndex==1){

// button 1 tapped

NSLog(@"OK %d", buttonIndex);

}
