ios - How to add these two values together in objective c -



ios - How to add these two values together in objective c -

i'm stuck adding these values together. both come .plist. both numbers. want add together values , display result string in label.

nsinteger calories = [[self.main objectforkey:@"calories"] integervalue]; nsinteger calories2 = [[self.apps objectforkey:@"calories"] integervalue];

i want go

nsstring *totalcalories = calories + calories2; self.calorielabel.text = totalcalories;

but not work. i'm new , sense i'm missing little , obvious.

any insight?

you’re there far add-on itself:

nsinteger totalcalories = calories + calories2;

now need convert number string, can this:

nsstring *totalcaloriestext = [nsstring stringwithformat:@"%d", totalcalories];

the problem trying treat integer look (calories + calories2) string. valid thing in programming languages, in objective-c have explicit such conversions.
