    UILabel* localizedAppNameLabel = [[UILabelalloc]initWithFrame:

                                      CGRectMake(20+15,0,screenWidth -40-15,20)];

    UIFont* labelFont = [UIFontsystemFontOfSize:11.0f];

    localizedAppNameLabel.font= labelFont;

    localizedAppNameLabel.textAlignment=NSTextAlignmentCenter;

    localizedAppNameLabel.text= localizedAppName;

    CGSizelocalizedAppNameLabelSize = [localizedAppNameLabel.text

                                        sizeWithAttributes:

                                         [NSDictionarydictionaryWithObjectsAndKeys:
