ios - 如何判断一个类是系统的还是自定义的？

Question

大家好!

如何判断一个类是系统类还是自定义类？

Custom的Class也是继承自NSObject。

如何区分？

拜托，谢谢～

补充，像这样:

- (void)aaaa:(Class)aCustomClass
{
    id instance = [[aCustomClass alloc] init];
    NSArray * array = GET_A_CLASS_ALL_PROPERTY(aCustomClass);  //it is a NSString array.
    for (NSString * property in array)
    {
        Class classOfTheProperty = GET_THE_PROPERTY_CLASS(property);  //the property's Class.
        if ([classOfTheProperty isKindOfClass:NSString.class])
        {
            [instance setObject:@"1234" forKey:property];
        }
        else if (IS_CUSTOM_CLASS)  //CUSTOM_CLASS maybe has less one hundred.
        {
            //Continue inner.
            [self aaaa:classOfTheProperty];
        }
        else if (IS_SYSTEM_CLASS)  //SYSTEM_CLASS definite has more than hundreds.
        {
            //Do Nothing.
        }
    }
}

您可以检查该类是否是从应用程序的主包中加载的，而不是从框架中加载的:

    Class c = ...
    NSBundle *b = [NSBundle bundleForClass:c];
    if (b == [NSBundle mainBundle]) {
        // Custom class ...
    }
