NSString删除换行符（Objective-C）

Question

我将数据从XML加载到我的NSString，但数据的格式如下：

    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，如何删除它以使文本看起来像这样（全部在一行）：

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,
