iOS UIButton

[Nnavick]

Hi all,
I created a timer that connect to a method that creates buttons.
Evrey time the methods is running it overriding the last button and create new one(but keeps the old one active on screen).
In C# when you want to point to an the obcject you click on it you'r writing

this.bla bla;

there is parallel function in objective C/Cocoa Touch that mean the same as "THIS"?(maybe "SELF")?

Thanks !!

There is self but I suspect that's not what you're wanting. Do you want a pointer to the UI object that triggered the action?

Also, what is your experience level with Objective-C and Cocoa Touch programming? What have you done to educate yourself on the fundamentals?

I started to program a month ago, but I think my level is pretty good.
I have already set a target method that increase points when you click on the object(UIbutton).
what i meant is that when you click the button, the method tell the APP that you clicked the currently button that already override and remove it from super view, actually it's what you said,
so I tried

[Self RemoveFromSuperView]

but it changed the background to white,I think it has removed the UIVIEW.

Do you have any idea how to point to the currently button I click on it?

Based on your other thread, I see you've learned how to use addTarget:action:forControlEvents:. So, when you have your action method set up like so:

- (void)action:(id)sender {

what do you think sender is?

[Self RemoveFromSuperView]

Even if self was UIButton this would still fail. Check your case.


Do not rush your learning. This is the reason I ask if you understood the code.

I think sender could be used to verify identity of the object, but I am not sure if I understood.
I mean,i know what is the method behind sender but not sure if I understood is well

Yeah, unfortunately, I don't think you are understanding it either. You don't appear to have a good enough grasp of the basic fundamentals of iPhone programming and Cocoa Touch. I would suggest you step back from the real coding for now and go (re)learn those before you continue with your app.

 

[Nnavick]

It's the only thing that missing in my APP ,anyway I will relearn the basic.
hmm,what I am trying to do is possible?

No. In fact, not only is it quite possible, it's also quite common.

 

[Nnavick]

No. In fact, not only is it quite possible, it's also quite common.

Sorry,I didn't ֿֿֿ understand what you mean.
Is it possible or not?

 

[dejo]

Oops. Sorry. Not sure why I typed that. What I meant to say was:
Yes, it is possible.

haaaaaaaaaaaaaaaaaaaaaaaa
I tried to write

[ sender removeFromSuperview];

and it's works,because the function takes the ID of the button(every button has special attribute) and place the ID at the Sender argument,
so if I am turning to the Sender it's takes the attribute of the current button I clicked on it the remove the button from the view

 

[dejo]

...because the function takes the ID of the button(every button has special attribute) and place the ID at the Sender argument

Well, that's not how I would phrase it. sender is being set to a pointer to the object that triggered the action. You've just defined the method to accept the generic-type of id rather than a specific datatype, such as UIButton*.

But I'm glad you got your code working, through your own process of discovery.
