Center UIPickerView Text

Question

So I have a uipickerview with rows that only contain the number 0-24 and it looks a bit silly since the numbers are left aligned leaving a huge gap on the right of the picke

Answer 1

Just set the width to the width of the view and the text will center automatically:

- (CGFloat)pickerView:(UIPickerView *)pickerView widthForComponent:(NSInteger)component {
    return self.view.bounds.size.width; 
}

Answer 2

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view
{
    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 300, 37)];
    label.text = [NSString stringWithFormat:@"something here"];
    label.textAlignment = NSTextAlignmentCenter; //Changed to NS as UI is deprecated.
    label.backgroundColor = [UIColor clearColor];
    [label autorelease];
    return label;
}

or something like this.

Answer 3

You can implement this delegate method, which returns a CGFloat

- (CGFloat)pickerView:(UIPickerView *)pickerView widthForComponent:(NSInteger)component

This is called on the picker view to determine row width.
