ios：用返回值替换NSString中的单词

Question

我有以下NSString：

"This is a test String
*This a test string"

我想用这样的回报替换“*”

"This is a test string

This is a test string"

我试过了：

[removeStr stringByReplacingOccurrencesOfString:@"*" withString:@"/r"];

但它打印“/ r”，当我尝试“\ r”时，我得到一个lldb错误

任何帮助？

Answer 1

NSString *str = @"This is a test String*This a test string";
NSString *str2 = [str stringByReplacingOccurrencesOfString:@"*" withString:@"\n"];
NSLog(@"%@", str2);

如果字符串如此，则替换\n，结果为：

This is a test String
This a test string
