NSCharacterSet
NSString -stringByTrimmingCharactersInSet: 是个你需要牢牢记住的方法。它经常会传入 NSCharacterSet +whitespaceCharacterSet 或 +whitespaceAndNewlineCharacterSet 来删除输入字符串的头尾的空白符号。需要重点注意的是，这个方法 仅仅 去除了 开头 和 结尾 的指定字符集中连续字符。这就是说，如果你想去除单词之间的额外空格，请看下一步。假设你去掉字符串两端的多余空格之后，还想去除单词之间的多余空格，这里有个非常简便的方法：NSString *string = @"Lorem
ipsum dolar
amet.";string = [string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];NSArray *components = [string componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];components = [components filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"self && ''"]];string = [components componentsJoinedByString:@" "];首先，删除字符串首尾的空格；然后用 NSString -componentsSeparatedByCharactersInSet: 在空格处将字符串分割成一个 NSArray；再用一个 NSPredicate 去除空串；最后，用 NSArray -componentsJoinedByString: 用单个空格符将数组重新拼成字符串。注意：这种方法仅适用于英语这种用空格分割的语言。
