Simple BMI calculator?

[tobban2]

Hello! Guess it's simple for some of you, but I would appreciate a simple BMI calculator. Just a view with an info-button and two fields, one for length and one for weight. Then a label that will be updated when a button is pressed. Simple for those who know how to do it. Hard for everyone else!

Dude, you can make this using other tutorials. Just piece them all together. Or just learn iOS development instead of using "tutorials" to put out crap apps.

this sounds a lot like another "can you write my app for free?" type post to me. Like bertrand said, you can learn everything you would need for this app in other, very basic tutorials

The thing is that I've got my BMI calculator up and running. But I won't learn if i'm doing it right if I can't check somehow how it should be done. And it's not for AppStore

edit: Hang on and I'll come with my source code soon

fifth try now:

MainViewController.h
IBOutlet UILabel *bmiLabel;
IBOutlet UITextField *length;
IBOutlet UITextField *weight;
-(IBAction)countBMI;

MainViewController.m
int bmiInt = 0;

-(IBAction)countBMI{
double weightInt = [weight.text doubleValue];
double lengthInt = [length.text doubleValue];
bmiInt = weightInt/(lengthInt*lengthInt);
NSString *bmi = [NSString stringWithFormat:@"%d", bmiInt];
bmiLabel.text = bmi;
}

edit: how to use double? if I set bmiInt to a double I got wrong data to bmiLabel. (just change %d to %f, right?) - What if i want to round it to .5? like 3.2 = 3.0, 3.3 = 3.5? Trying some with @"%f", (round)bmiInt];
