我目前正在尝试传递代理,但编译器正在给我一条警告消息 “八进制转义序列超出范围”
NSURLCredential *credential = [NSURLCredential credentialWithUser:@"asdfg\123456"
password:@"Zxcvb123!" persistence:NSURLCredentialPersistenceForSession];
我如何删除此警告?

如果'\'只是用户凭据的一部分,则需要将其转义:
NSURLCredential *credential = [NSURLCredential credentialWithUser:@"asdfg\\123456"
password:@"Zxcvb123!" persistence:NSURLCredentialPersistenceForSession];

问题是用户名中的\(反斜杠)。 \是一个转义字符,当用作\ 121时,它将121解释为八进制数。如果您想在用户名中使用n,请将其写为
NSURLCredential *credential = [NSURLCredential credentialWithUser:@"asdfg\\123456"
password:@"Zxcvb123!"
persistence:NSURLCredentialPersistenceForSession] ;
