UIAlertView is a class to display alert messages on screen. For iOS 8+, see also UIAlertController.
Showing with Undo dialog animation
Signature | -(void)showWithAnimationType:(int)type; |
---|---|
Available in | 3.0 – |
Unlike all other dialogs which pops up, the Undo dialog appears by jiggling in from the side. You can do so with [alert showWithAnimationType:1].
Adding text fields

---|---|
Available in | 2.0 – |

Signature | -(UIAlertSheetTextField*)textField; |
---|---|
Available in | 2.0 – |
Signature | -(NSInteger)textFieldCount; |
---|---|
Available in | 2.0 – |
You can create multiple text fields using the -addTextFieldWithValue:label: method. If you only need 1 text field, using the -textField method will automatically create only 1 for you. When the alert view has text fields, it will only be available in portrait position.
Subtitle and tagline
Signature | @property(nonatomic,copy) NSString* subtitle; |
---|---|
Available in | 2.0 – |
Signature | -(void)setTaglineText:(NSString*)taglineText |
---|---|
Available in | 2.0 – |
Subtitle and tagline are two additional styles of text which you could place on an alert view. Subtitle appears below the title, and tagline appears below the message.
