NSMutableArray UIButtons Action? - iphone

Question

I am Creating UIButtons programmatically and Then Store these UIButtons in NSMutableArray. All these UIButtons have Some Text as Titles. I have No Outlet for These UIButtons. Now I want to Assign the Title of UIButton to UIlabel when I touch or Click some UIButton. But the problem for me is this: how can I perform the function on these UIButtons. Because I created UIButtons programmatically and also these UIButtons have No Outlet. Here is my code to create Buttons:
saveBtn = [[NSMutableArray alloc] init];
for (int i=0; i<30; i++) {
if (btnn>8) {
UIButton *btn = [UIButton
buttonWithType:UIButtonTypeRoundedRect];
btn.frame = CGRectMake(200.0 , spacey, 30.0, 30.0);
int idx;
idx = arc4random()%[arr count];
NSString* titre1 = [arr objectAtIndex:idx];
[btn setTitle:titre1 forState:UIControlStateNormal];
spacey=spacey+30;
spacex = 80;
btnn = 0;
}
else {
btnn++ ;
UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btn.frame = CGRectMake(spacex, spacey, 30.0, 30.0);
int idx;
idx = arc4random()%[arr count];
NSString* titre1 = [arr objectAtIndex:idx];
[btn setTitle:titre1 forState:UIControlStateNormal];
spacex = spacex + 30;
[saveBtn addObject:btn];
[self.view addSubview:btn];
}
}
Please any one can guide me how can perfom action for these NSMutableArray UIButtons.

Answer 1

You can add actions to an UIButton programmatically using:
[button addTarget:self action:#selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
- (void)buttonClicked:(UIButton *)btn
{
[btn setTitle:#"UnAutreTitre" forState:UIControlStateNormal];
}
Hope this helps.

Simply set tag and add target to the button. Later, you can get which button was tapped.

Answer 3

Create the action for the UIButton action, where you will be sending the (id)sender to the actionButtonFunction.
Assign sender to UIButton and then take the button title in NSString.
-(UIAction)buttonAction:(id)sender
{
UIButton *button = (UIButton *)sender;
NSString *buttonTitle = button.text;
// further code goes here
}
