ios - 请求非结构或联合 :error 中的成员 "nameField"

Question

我的错误消息:

Request for member "nameField" in something not a struct or union

我的错误代码:

NSString *msg = nil;
if (nameField.text.length > 0)
    msg = [[NSString alloc] initWithFormat:@"Relax, %@, all is good".nameField.text];
else
    msg = @"Relax, all is good";

Answer 1

你的代码行

msg = [[NSString alloc] initWithFormat:
       @"You can breathe easy,%@, EveryThing went ok". nameField.text];

试试这个

msg = [[NSString alloc] initWithFormat:
       @"You can breathe easy,%@, EveryThing went ok", nameField.text];
                                                     ^

更改的行是你已经使用过的。此处不用逗号 -> :@"...",

检查这是否有帮助
