[NSString stringByReplacingOccurrencesOfString:@"""withString:@""""];

Question

我有一个NSString并希望以CSV格式保存它.正因为如此,我替换所有"带"".我尝试了以下代码,但编译器报告错误.

newString = [oldstring stringByReplacingOccurrencesOfString:@""" withString:@""""];

oldstring是哪里11th ave, "L&T", Khar.oldstring是根据用户输入设置的.

我怎样才能将newString设置为11th ave, ""L&T"", Khar？

任何帮助将不胜感激.

你需要"在字符串中转义双引号():

newString =  [oldString stringByReplacingOccurrencesOfString:@"\"" withString:@"\"\""];
