Changing text on label with button click
Domanda
I want to know how we can change text on label with button click,i have 2 buttons named add and minus,if we click on add button,on each click ,it will increase from 1-10,and if we click on minus button ,it should reduce from 1-10,
I tried to do some stuff,which is below
-(IBAction) addQuantity
{
for (int i=1;i<11; i++)
{
[m_label setText:[NSString stringWithFormat:@"%i",i]];
}
}
please friends explain me how to proceed,
Regards Ranjit
Soluzione
NSInteger counter = 0;
-(IBAction) addQuantity
{
if (counter > 9 )
return;
[m_label setText:[NSString stringWithFormat:@"%d",++counter]];
}
-(IBAction) minusQuantity
{
if (counter < 1 )
return;
[m_label setText:[NSString stringWithFormat:@"%d",--counter]];
}
