Question

我有2种方法向我发出警告:

id LoadObjectFromFile(NSString* filename) {
    if ((filename = DocumentPath(filename, NO))) {
        return [NSKeyedUnarchiver unarchiveObjectWithFile: filename];
    } else {
        return nil;
    }
}

BOOL saveObjectWithFile(NSString* filename, id object) {
    if ((filename = DocumentPath(filename, YES))) {
        return [NSKeyedArchiver archiveRootObject: object toFile: filename];
    } else {
        return NO;
    }
}

这给我带来了“以前没有职能原型”的警告。

I d rather not just disable the warnings in xcode.

Where am I going wrong?

Answer 1

this are C functions not objective C methods. have you defined them in the .h file?
