Detect which Button is pressed?

StefanL · 10-21-2010, 04:10 PM

Hi Folks,

I am creating a couple of Buttons dynamically like this:

Code:

 

t = 0;
x = 10;
y = 10;

for (i=0; i < [count intValue]; i++ ){

		 UIImage *imageLoop = [UIImage imageNamed:[[companyName objectAtIndex:i ]stringByAppendingString:@".png"]];
		 
		 NSLog(@"NSMutableArray: %@", [companyName objectAtIndex:i]);
	
		 
		 UIButton* button = [[UIButton alloc] init];
		 
		 [button setImage:imageLoop forState:UIControlStateNormal];
		 [button setImage:imageLoop forState:UIControlStateHighlighted];
		 

		 [button addTarget:self action:@selector(productImagePressed:)
		  forControlEvents:UIControlEventTouchUpInside];
		 button.tag = t;
		 button.frame = CGRectMake(x,y,100,100);
		 [self.view addSubview:button];
		 [button release];
		 
		 x = x + 120;
		 y = y;
		 t = t + 1;
		 
	 }

In my "productImagePressed" Method I am logging like this:

Code:

-(IBAction)productImagePressed:(id)sender {
	
	NSLog(@"Pressed = %@", [companyName objectAtIndex:t]);
	
}

But I am not able to get the correct number - I know that my "t" is wrong, but how can I fetch the pressed button?

Thanks for your Feedback and Advice.

[sender tag]

Hi Brian,

thanks!

Code:

-(IBAction)productImagePressed:(id)sender {
	
	UIButton *button = (UIButton*) sender;
	NSLog(@"Clicked button %d", button.tag);
	
}

does it! :-)

BR,

Stefan
