I wanted to show an alertView to a user with a textField. This is what was achieved:
\n\"\"<\/a>
\nFirst, I tried to use Block Alerts and ActionSheets, but I failed. Then I discovered, that there is a standart way to do this. There are some UIAlertView styles available beyond a default style: UIAlertViewStyleLoginAndPasswordInput, UIAlertViewStylePlainTextInput and UIAlertViewStyleSecureTextInput. In this case we will use the second one. Works on iOS 5 and later:<\/p>\n

<br \/>\nUIAlertView *av = [[UIAlertView alloc] initWithTitle:LS(@\u201dDocument file name\u201d) message:@\u201dPlease enter document file name.\u201d delegate:self cancelButtonTitle:LS(@\u201dCancel\u201d) otherButtonTitles:LS(@\u201dSave\u201d), nil];<br \/>\nav.alertViewStyle = UIAlertViewStylePlainTextInput;<br \/>\n[av textFieldAtIndex:0].delegate = self;<br \/>\n[av textFieldAtIndex:0].text = self.mcAttachDisplayed.fileName;<br \/>\n[av show];<br \/>\n<\/code><\/pre>\n
Then, you should define two protocols UITextFieldDelegate, UIAlertViewDelegate.
\nAnd implement methods: <\/p>\n
<br \/>\n\u2013 (BOOL)textFieldShouldReturn:(UITextField *)textField<br \/>\n{<br \/>\n    [textField resignFirstResponder];<br \/>\n    return YES;<br \/>\n}<\/p>\n<p>\u2013 (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex<br \/>\n{<br \/>\n    NSLog(@\u201dButton index clicked:%d\u201d, buttonIndex);<\/p>\n<p>    switch (buttonIndex) {<br \/>\n        case 0:<br \/>\n            break;<br \/>\n        case 1:{<br \/>\n            NSLog(@\u201dSave Clicked\u201d);<br \/>\n            UITextField *textField = [alertView textFieldAtIndex:0];<br \/>\n            NSString *text = textField.text;<\/p>\n<p>            break;<br \/>\n        }<br \/>\n        default:<br \/>\n            break;<br \/>\n    }<br \/>\n}<br \/>\n<\/code><\/pre>\n
