在UILabel之后放置一个UIImage
问题描述：
我希望UILabel的最大宽度为100，之后是UIImage，我该如何在界面构建器中执行此操作？我希望如果文本较短，标签小于100，但UIImage就在标签后面。
I want to have an UILabel with a max width of 100 and after that an UIImage, how can I do that in interface builder? I want that if the text is shorter the label is less than 100 but the UIImage is right behind the label.

你可以用这样的代码来做：
you can do it with code like this:
首先初始化标签和imageView
first init the label and the imageView
_label = [[UILabel alloc] initWithFrame:CGRectZero];
_imageView = [[UIImageView alloc] initWithFrame:CGRectMake(label.frame.origin.x + label.frame.size.width, label.frame.origin.y, 30, 30)];
然后当标签有文字时，你可以计算标签框架的宽度
then when the label has text , you can calc the width of the label`s frame
CGSize size = [_label.text sizeWithFont:[UIFont boldSystemFontOfSize:15]];
CGFloat width = size.width > 100 ? 100 : size.width;
CGFloat height = size.height;
_label.frame = CGRectMake(0, 0, width, height);
