在UILabel之后放置一个UIImage [英] Place an UIImage after an UILabel

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.

推荐答案

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);
