NSString 删除换行符 (Objective-C)

Question

我正在将数据从 XML 加载到我的 NSString，但数据格式如下：

    Lorem ipsum dolor sit amet, 
    consectetur adipiscing elit. 
    Sed a velit ut nulla tincidunt finibus sit amet sed felis. 
    Fusce quis quam sapien.

它有换行符，我怎样才能修改它，所以文本看起来像这样（全部在一行中）：

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed a velit ut nulla tincidunt finibus sit amet sed felis. Fusce quis quam sapien. Cras diam metus, viverra in urna sed, efficitur varius sem. Pellentesque accumsan, lectus at rutrum pulvinar, 

Answer 1

试试这个

NSString *newString = [[oldString componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]] componentsJoinedByString:@" "];
