  • 0

I’m using this code to attempt to convert a float to an int, then use it for UILabel text:

[progLabel setText:[NSString stringWithFormat:@"Deck Progress %i%%",progBar.progress*100]];

and I’ve tried this:

[progLabel setText:[NSString stringWithFormat:@"Deck Progress %i%%",(int)progBar.progress*100]];

The displayed text is always “0%”.

I also tried this which works:

int pval=progBar.progress*100;
[progLabel setText:[NSString stringWithFormat:@"Deck Progress %i%%",pval]];

I’ve tried %f%% but that gives me too many digits – I’m trying to get only 0-100, no decimal places.

What am I doing wrong?

    The (int) is applied only to progBar.progress because casting has higher precedence than multiplication, and (int)progBar.progress is always 0 if 0 ≤ progBar.progress < 1. You need to cast the whole expression like

    (int)(progBar.progress * 100)

    Alternatively, you could avoid casting at all, by using a format of floating point which does not show the fractional part.

    [NSString stringWithFormat:@"Deck progress %.0f%%", progBar.progress * 100]
