ios - 向UILabel添加额外的空间以插入图像

Question

我在UILabel文本的末尾添加图像时遇到问题。如何检测标签中文本的大小，然后添加额外的空间并在其中插入图像？

我为此写了一些代码:

-(void) labelSizeGetter
{
    UILabel * mylabel=[[UILabel alloc] initWithFrame:CGRectMake(0, 0, 0, 0)];

    float heigth=25.0;//max height value of label.

    NSString *yourString = @"My great text";

    mylabel.font =[UIFont fontWithName:@"Helvetica-Bold" size:12];

    [mylabel setText:yourString];

    CGSize s = [mylabel.text sizeWithFont:[UIFont systemFontOfSize:12] 
                        constrainedToSize:CGSizeMake(MAXFLOAT,heigth)
                            lineBreakMode:NSLineBreakByWordWrapping];

    // s is a size for text of label. just add 10 pix to width to make it more beautiful.

    NSLog(@"%@", NSStringFromCGSize(s));

    mylabel.frame=CGRectMake(0, 0, s.width+10, s.height);

    [self.view addSubview:mylabel];

    UIView * myimage=[[UIView alloc] initWithFrame:CGRectMake(mylabel.frame.origin.x+mylabel.frame.size.width , mylabel.frame.origin.y, 30, 30)];//create your images frame according to frame of your label

    myimage.backgroundColor =[UIColor colorWithPatternImage:[UIImage imageNamed:@"arti.png"]];

    [self.view addSubview:myimage];

}

我希望它会有所帮助
