有谁知道如何为UILabal制作最小字符？ （迅速）

Question

有谁知道如何为UI标签制作最小字符？ 比如Twitter每条推文有142个字符。

Answer 1

你需要的就是像这样修剪字符串：

let maxLength = 142 //char length
if originalString.count > maxLength {
    let range =  originalString.rangeOfComposedCharacterSequences(for: originalString.startIndex..<originalString.index(originalString.startIndex, offsetBy: maxLength))
    let tmpValue = originalString.substring(with: range).appending("...")
}
