Adding an UITextField to an UIAlertView in iPhone / iOS application


As we all know, UIAlertView is subclassed from UIView, its possible to add sub views to the alert view.

Today, we will try to add an text field to UIAlertView. The code is attached below.


    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"See the text field below"     message:@"this gets covered!\n"  delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:@"OK", nil]; 
    alert.tag = 1000;
         UITextField *_textField = [[UITextField alloc] initWithFrame:CGRectMake(12, 45, 260, 25)];
    [_textField setPlaceholder:@"Place holder text"];
    _textField.tag = 100;
    _textField.clearButtonMode = UITextFieldViewModeWhileEditing;    [_textField setBackgroundColor:[UIColor whiteColor]];    [_textField becomeFirstResponder];    [alert addSubview: _textField];
    [_textField release];
    [alert show];
    [alert release];

And to get the value of the text field, use the viewWithTag parameter to identify the text field.


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



UITextField *_textField = (UITextField *) [actionSheet viewWithTag:1];        NSLog(@"Entered text in alert view:  <%@>", [_textField text]);}

In the same manner, we can add UIImageView to alert view.

Multiple line of text in UIPickerView

UIPickerView is a user interface component available from iOS 2.0 and above. The basic need of UIPickerView is to select any one option from the list of data that are loaded to the picker view. But, by default, only one line of text is allowed to be displayed in a UIPickerView . Today, we will try to add multi-line text to an UIPickerView . To do so, we need to implement the viewForComponent api.   - ( UIView  *)pickerView:( UIPickerView  *)pickerView viewForRow:( NSInteger )row forComponent:( NSInteger )component reusingView:( UIView  *)view; In that method, type cast the view parameter to an UILabel.    UILabel *pickerLabel = ( UILabel *)view; Update the frame size of the label.    CGRect frame = CGRectMake ( 0 , 0 , 265 , 40 );    pickerLabel = [[[ UILabel alloc ] initWithFrame :frame] autorelease ]; Set the properties of the label as per requirement.    [pickerLabel setTextAlig...
