    unsigned int count = 0;
    Ivar *ivars = class_copyIvarList([UITextField class], &count);
    NSLog(@"count = %d", count);
    for (int i = 0; i < count; i++) {
        Ivar ivar = *(ivars + i);
        // 或
        // Ivar ivar = ivars[i];
        NSLog(@"%s", ivar_getName(ivar));
    }

    // 释放内存
    free(ivars);
