Question

So I am trying pass in parameters to my “buttonClicked” function so that I can dynamically control what happens when you click the button. Every way that I try to do it on my own just breaks my code. I have searched many different sites and answers on stackOverflow, but I can’t seem to find an answer. I am fairly new to objective C, especially with functions, So I could really use some help figuring out how to do this. Thanks in advance

Here is my code thus far and what I am trying to do:

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
NSLog(@"Hi 1!");

[button addTarget:self action:@selector(buttonClicked:buttonType:buttonID:) forControlEvents:UIControlEventTouchUpInside];

button.frame = CGRectMake(buttonViewXvalue, buttonViewYvalue, buttonViewWidth, buttonViewLength);

[self.view addSubview:button];  

Then the Declaration in the Header File:

- (IBAction)buttonClicked:(id)sender theButtonType: (int)buttonType: theButtonID: (int) buttonID;

and the implementation:

- (IBAction)buttonClicked:(id)sender theButtonType: (int)buttonType: theButtonID: (int)    buttonID 
{
//Here I would use the buttonType and buttonID to create a new view. 
NSLog(@"Hi!");

}

You can’t use multi-parameter methods with addTarget:action:forControlEvents:. Instead you might set the button’s tag, then look up information later based on the tag.
