ios:用返回替换 NSString 中的单词

Question

我有以下 NSString:

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

我想用这样的返回替换“*”

"This is a test string

This is a test string"

我试过:

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

但它打印“/r”，当我尝试“\r”时，我得到一个 lldb 错误

有什么帮助吗？

Answer 1

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

如果是这样的字符串，替换\n，则结果为:

This is a test String
This a test string
