在我的应用程序中,我有一个标签,文本来自服务器所以我不知道它的宽度,并且在这个标签的末尾直接应该有一个UIImage。
我的问题是:由于标签文字的非静态宽度,我不知道如何定位图像。
更清楚的是,这是设计的快照,应该如何:
有任何解决这个问题的建议吗?

您可以直接在标签上插入图片
var attachment = NSTextAttachment()
attachment.image = UIImage(named: "your_image_name")
var attributedString = NSAttributedString(attachment: attachment)
var labelString= NSMutableAttributedString(string: "Lorem ipsum dolor sit ame...")
labelString.appendAttributedString(attributedString)
yourUILabel.attributedText = labelString

我设法解决了这个问题。它不是最漂亮的代码,但它有效。我从标签的最后一行返回单词数字,我可以从中计算文本结束的宽度,图像开始(x,y)坐标。
func lastWordInTitle(title: String) -> Int {
var separateWords: [String] = []
var sizeOfWords: [CGFloat] = []
var wordsRemaining: Int = 0
var wordsWidthInOneLine: CGFloat = 0
let font = titleLabel.font
let fontAttr = [NSAttributedStringKey.font: font]
title.enumerateSubstrings(in: title.startIndex..<title.endIndex, options: .byWords) { (substring, _, _, _) in
if let substring = substring {
separateWords.append(substring) // number of words in label
sizeOfWords.append(substring.size(withAttributes: fontAttr).width + 8) //size of each word + 8 for the space between them
}
}
wordsRemaining = separateWords.count
print("SSS wordsRemaining initial \(wordsRemaining)")
var wordsToRemoveIndex = 0
for index in 0..<separateWords.count {
wordsWidthInOneLine += sizeOfWords[index]
wordsToRemoveIndex += 1
if wordsWidthInOneLine > titleLabel.frame.width {
if index == separateWords.count - 1 {
wordsRemaining -= wordsToRemoveIndex
return 1
} else {
wordsRemaining -= wordsToRemoveIndex - 1 == 0 ? 1 : wordsToRemoveIndex - 1
wordsToRemoveIndex = 0
wordsWidthInOneLine = 0
wordsWidthInOneLine = sizeOfWords[index]
}
} else if wordsWidthInOneLine < titleLabel.frame.width && index == separateWords.count - 1 {
let reversedSeparateWordsSize = Array(sizeOfWords.reversed())
var width: CGFloat = 0
for index in 0..<wordsRemaining {
width += reversedSeparateWordsSize[index]
}
if width > titleLabel.frame.width {
return wordsRemaining - 1
}
return wordsRemaining
}
}
return wordsRemaining
}

实际上,它取决于...
您可能希望使用sizeToFit
或sizeThatFits
方法。

UILabel
UILabel
。frame.width yourUILabel
的宽度
将UIImage
的x坐标设置为yourUILabel.frame.width + emptySpace
,如此
var yourUIImageView:UIImageView = UIImageView(frame: CGRectMake(x:PaddingFromLeft + yourUILabel.frame.width + emptySpace, y: yourYCoordinate, width: yourImageWidth, height : yourImageHeight))
