Pass different parameters to an IBAction

Question

My iPhone app has many buttons and I want all the buttons to call the same method, but with different parameters.

For example I want tapping one button to call the m

Answer 1

the real reason You cannot add additional parameter is that UIKIT will push params on the stack. so the only way is to use tags. A DIRTY way can be to convert a pointer to int and tagging the button with it:

myStruct params;
// fill params:
params.x=....
params.y=....
params.z=....


UIButton * btn = [UIButton......]; // create or use one from XIB
btn.tag = (int)¶ms;

... in Call back:
-(IBActions) doIt:(id)sender
{
  myStruct * paramsPtr = (myStruct*)tag;
  int i = paramsPtr->x;

NOTE: params MUST be keep static .. or allocate using malloc (more and more ugly code...). DO NOT use a local var: it will be allocated on stack so will be removed after exiting from the setup method.
