UILabel 使用如下：

@implementation ViewController

@synthesize _uiLabel;

-(void)popToRootVC
{

}

- (void)viewDidLoad
{
    [super viewDidLoad];
    
    UIBarButtonItem *rightItem = [[UIBarButtonItem alloc] initWithTitle:@"Root" style:UIBarButtonItemStylePlain target:self action:@selector(popToRootVC)];
    self.navigationItem.rightBarButtonItem = rightItem;

    
    //定义设置ios7 满足要求，设置所有view组件下移64像素
    /*
    if([[[UIDevice currentDevice] systemVersion] doubleValue] >= 7.0)
    {
        self.navigationController.navigationBar.translucent = NO;
    }
     */
    
    //self.automaticallyAdjustsScrollViewInsets = YES;
    [self.navigationController setNavigationBarHidden:NO];
    [self.navigationController setToolbarHidden:NO];
    
    _uiLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 40, 100, 20)];
    _uiLabel.text = @"文本信息显示";
    _uiLabel.font = [UIFont fontWithName:@"Arial" size:20];
    _uiLabel.textColor = [UIColor blackColor];
    _uiLabel.layer.cornerRadius = 5.0f;
    _uiLabel.layer.borderWidth = 0.3f;
    _uiLabel.textAlignment = NSTextAlignmentCenter;
    _uiLabel.layer.borderColor = [UIColor darkGrayColor].CGColor;
    _uiLabel.layer.backgroundColor = [UIColor greenColor].CGColor;
    /*
    UIColor *selfColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"position_location_img.png"]];
    _uiLabel.layer.backgroundColor = selfColor.CGColor;
    */
    
    /**
     *  UILabel 大小自适应
     */
    //_uiLabel.shadowColor = [UIColor blackColor];
    //_uiLabel.shadowOffset = CGSizeMake(1.0, 1.0);
    
    _uiLabel.tag = 101;
    /**
     *  设置粗体
     */
    _uiLabel.font = [UIFont boldSystemFontOfSize:20.0];
    /**
     *  通过改变字体大小适应UILabel的宽度
     */
    _uiLabel.adjustsFontSizeToFitWidth = YES;
    /**
     *  设置高亮
     */
    _uiLabel.highlighted = YES;
    _uiLabel.highlightedTextColor = [UIColor blackColor];
    _uiLabel.lineBreakMode = NSLineBreakByTruncatingMiddle;
    _uiLabel.userInteractionEnabled = YES;
    
    [self.view addSubview:_uiLabel];
    
}

-(void)awakeFromNib
{
    
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];

}
