double -> string formatting

[Glnn]

I'm having trouble formatting a double to a string..

This is the code is use..

secondLabel.text = [NSString stringWithFormat:@"%i.%i", second, millisecond];

NSString *convert = [NSString stringWithFormat:@"%i.%i", second, millisecond];
kilometers = [convert doubleValue];
kilometers = kilometers * 2.9;
meterLabel.text = [NSString stringWithFormat:@"%d", kilometers];

and this is the result..



Anybody?

Couple things: (1) it's not clear from your post which snippet of code is responsible for the image that you posted, (2) "%d" is for integers and shouldn't result in a number with a decimal point, and (3) you haven't specified exactly what output you're looking to achieve.

Here's a link to some Apple documentation on string formatters: String Programming Guide for Cocoa: String Format Specifiers.

You're right..
The way I'm asking the question isn't really good..

The link you posted, it helped me..
So thank you
