Theos实例方法调用

Question

I have searched for an answer to this and cannot find one.

How would I call an instance method in the same class I am hooking in my Theos tweak? If I was using standard Xcode i would use the self method ie-

[self method:arg];

But in a theos tweak this says cannot find the method, even if i hook that method.

Example:

%hook classimhooking

-(void)methodimhooking
{
    [classimhooking methodiwanttocall];
    [self methodiwanttocall];
    %orig;
}

-(void)methodiwanttocall
{
    %orig;
}

%end

The methodiwanttocall is there and i can hook to it, just not call it. I have tried adding a new method with %new and calling that but it is not found, i have tried the same with a delay, but it is not found. I have tried defining a variable of my class and calling that but it doesn't work.

I can also see that you can grab iVars directly, but this doesn't work with methods.

Any ideas would be appreciated.

Answer 1

如果要在刚挂接的对象上调用方法，可以使用performSelector （或performSelector:withObject:如果它有参数），这应该是这样的：

[self performSelector:@selector(methodiwanttocall)];

Answer 2

Sorry to dig an old thread. I may have an idea about the issue here. In case anyone with the same issue comes across this.

The problem is that the compiler does not know there is such a method, even there is. The way to deal with it is to import the header at the top of the code.

#import <classimhooking>
