i have a problem with uibutton action. I want send argument when the button clicked. i saw some examples that work with tag prop. and the class is id sender. but i dont want to fixed it. the action goes to my own manager. how can i do ?
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton addTarget:self
action:#selector(goToSubViewManager:)
forControlEvents:UIControlEventTouchUpInside];
here is the gotosubviewmng
- (void)goToSubViewManager:(ViewType*)vTipi
{
}

Answer 1

you should only use - (void)goToSubViewManager:(id)sender. or - (void)goToSubViewManager
so here are 2 ways to solve your problem.
you can use variables or property.
- (void)yourMethod
{
//your code
_vTipi = yourVTipi;
}
- (void)goToSubViewManager
{
//here you can use _vTipi;
}
you can add a Category for the UIButton , to add an id type property(such as #property(nonatomic) vTipi).faking instance variables for UIButton.(how to do you can look at this : http://oleb.net/blog/2011/05/faking-ivars-in-objc-categories-with-associative-references/) Then you can use like this:
- (void)goToSubViewManager:(id)sender
{
//you can user ((UIButton *)sender).vTipi
}

Answer 2

Use can use tag property of the button. And then can use that object by comparing the tag assigned.
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton addTarget:self
action:#selector(goToSubViewManager:)
forControlEvents:UIControlEventTouchUpInside];
rightButton.tag=1;
//
then in the call back you can compare it as
- (void)goToSubViewManager:(id)sender
{
if(sender.tag==1){
// you can use an array of that object(if multiple), then apply your logic
}
}
