XCode警告:使用'stringWithString':文字是多余的

Question

我收到了以下警告

Using 'stringWithString': with a literal is redundant

在使用该方法时 usingWithString

[NSString stringWithString:@"Content-Type: content/unknown\r\n\r\n"]

Answer 1

我通过替换[NSString stringWithString:@"Content-Type: content/unknown\r\n\r\n"]来解决了这个问题@"Content-Type: content/unknown\r\n\r\n"
