替换< br>在带有新行的NSString中 [英] Replace <br> in an NSString with a new line

问题描述

我有这样的 NSString

NSString * string = @"textTextTextTextText< br> textTextTextText< br> TextTextText"

我想将此 NSString 设置为我的 UICell 的文本，并在该字符串上的每个
标记上换行.我该怎么办?

I want to set this NSString to be the text of my UICell with a new line on each
tag found on the string. How could I do that?

我已经尝试过了，但是没有成功:

I've tried this, without success:

cell.textLabel.text = [[文本componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]] componentsJoinedByString:@< br>"];

推荐答案

怎么样:

string = [string stringByReplacingOccurrencesOfString: @"<br>" withString: @"\n"]

或者，如果您使用的是Swift Strings

or, if you're using Swift Strings

var string = "textTextTextTextText<br>textTextTextText<br>TextTextText"
string = Array(string).reduce("") {$0 + ($1 == "<br>" ? "\n" : $1)}
