Tweak %new出来的方法，怎么在原对象的方法里怎么调用？

技能讨论
1

是我%new用错了还是调用方法错了？
Tweak.xm


%hook AddressBookFriendViewController 

- (void)initView{
    NSLog(@"initView befor: %d", (NSUInteger)[self hookListCount]);
    %orig;
    NSLog(@"initView after: %d", (NSUInteger)[self hookListCount]);
}
- (void)onAddContact{
    NSLog(@"onAddContact befor: %d", (NSUInteger)[self hookListCount]);
    %orig;
    NSLog(@"onAddContact after: %d", (NSUInteger)[self hookListCount]);
}
- (void)onContactsItemViewRightButtonClick:(id)arg1{
    NSLog(@"onContactsItemViewRightButtonClick: %@",arg1);
    %orig;
}

%new
-(NSUInteger)hookListCount{
    NSMutableArray *array = MSHookIvar<NSMutableArray *>(self, "m_arrAddressBookFriendList");
    return array.count;
}

%end

编译时报错：

你要把%new出来的方法也定义到头文件里去

3

tweak里要hook的类的头文件该怎么修改呢？书里theos章节里没找到，求详细说一说

4

在你自己的头文件里加上

@interface AddressBookFriendViewController
- (NSUInteger)hookListCount;
@end
5

我试过加在头文件,编译通过,运行直接报错,提示nrecognized selector sent to instance 0x17b99c00,能解答一下吗?

6

在自己的头文件中这样添加方法会不会覆盖原来头文件中的方法？

7

[self 方法名]

8

声明一下，跟C++里的@class作用类似
