- (NSMutableArray *)getArrayValue:(NSArray *)array{
     NSMutableArray *valueArray = [NSMutableArray array]; //value数组
    for (NSObject *object in array) {
        unsigned int numberofIvars = 0;
        Ivar* ivars = class_copyIvarList([object class], &numberofIvars);
        NSMutableArray *objectArray = [NSMutableArray array];
        for(const Ivar* p = ivars; p< ivars+numberofIvars;p++){
            Ivar const ivar = *p ;
            NSString* key = [NSString stringWithUTF8String:ivar_getName(ivar)];
            NSString *value = [object valueForKey:key];
            [objectArray addObject:value];
        }
        [valueArray addObject:objectArray];
    }
    return valueArray;
}

我在使用此方法时发生内存泄漏。

    free(ivars);
    return valueArray;
}

根据文档:“您必须使用 free() 释放数组”
