You have to use UIPickerViewDataSource,UIPickerViewDelegate methods for this.Create an array of your dates Which you are showing in the pickerView and use the following method.

- (void)pickerView:(UIPickerView *)pickerView didSelectRow: (NSInteger)row inComponent:(NSInteger)component 
{

[ closeButton setTitle:[NSString StringWithFormat:@"%@",[datesArray objectAtIndex:row]] forState:UIControlStateNormal];
}
