Answer 1

• 拆分字符串：

  NSArray *parts = [string componentsSeparatedByString: @"~"];
  

• 从数组中组装字符串：

  NSString *string = [parts componentsJoinedByString: @" "];
  

• 通过用空格替换~的所有出现来清理字符串：

  NSString *string = [string stringByReplacingOccurrencesOfString: @"~"\
                             withString:@" " ]
