如何知道标签最后一行的宽度? [英] How to know the width of last line of label?

问题描述

在我的应用中，我有一个标签，该文本来自服务器，因此我不知道其宽度，并且在该标签的末尾应该直接有一个UIImage.

我的问题是:由于标签文本的宽度非静态，我不知道如何放置图像.

更清楚地说，这是设计的快照，应如何设计:

请问有解决这个问题的建议吗?

解决方案

1. 设置 UILabel
的文本
2. 通过 yourUILabel .frame.width
获取此 UILabel 的宽度

3. 像这样在 yourUILabel.frame.width + emptySpace 上设置 UIImage 的x坐标

     var yourUIImageView:UIImageView = UIImageView(frame:CGRectMake(x:PaddingFromLeft + yourUILabel.frame.width + emptySpace，y:yourYCoordinate，width:yourImageWidth，height:yourImageHeight)) 

In my app I have a label which text came from the server so I don't Know its width, and at the end of this label directly there should be an UIImage.

My problem is: I don't know how to position the image because of the non static width of the label text.

To be more clear, this is a snapshot form the design and how should it be:

Any suggestion to solve this problem please?

解决方案

1. Set the text of the UILabel
2. Get the width of this UILabel with yourUILabel.frame.width

3. Set the x coordinate of your UIImage at yourUILabel.frame.width + emptySpace like this

   var yourUIImageView:UIImageView = UIImageView(frame: CGRectMake(x:PaddingFromLeft + yourUILabel.frame.width + emptySpace, y: yourYCoordinate, width: yourImageWidth, height : yourImageHeight))
