hi this may be considered a dumb question it just that iv been going around in circles for a bit now and im sure the solution is simple. i was playng around with an idea. in a single lable in a view when the view appears a random number is displayed. presently i have aview, a lable and a button. press button random number is generated and the lables title is replaced with a random number....random number displayed.

what i wish to acheive is that there is no button, just a view and a text lable and when the view appears a random number is displayed also instantaneously with out the need for a button to prompt generation.
here isi the code i have so far
#import "Mainview.h"

@implementation Mainview
- (IBAction)pushstart {

NSString *title = nil;
NSString *path = nil;

int Number = arc4random() % 12;
switch(Number) {
case 0:
namel.text = @"1";

break;
case 1:
namel.text = @"2";

break;

case 2:
namel.text = @"3";

break;

case 3:
namel.text = @"4";

break;

case 4:
namel.text = @"5";

break;
case 5:
namel.text = @"6";

break;

case 6:
namel.text = @"7";

break;

case 7:
namel.text = @"8";

break;

case 8:
namel.text = @"9";

break;



case 9:
namel.text = @"10";

break;

case 10:
namel.text = @"11";

break;

case 11:
namel.text = @"12";

break;


break;
default:
break;
}


}
@end
