Why doesn't Label receive string - iphone

Question

I have two views and two classes. On the first view, controlled by the first class I have a textfield and a button. On the second view controlled by the second class I have two labels. I tried to make one label receive the value I put on the text field, and the other label this value divided by 100. But on both cases I get 0.00, I don't know why!
firstclass.h
#import <UIKit/UIKit.h>
#interface NotasViewController : UIViewController{
}
-(IBAction)calcular:(id)sender;
-(IBAction)clicarFora:(id)sender;
-(IBAction)recuarTeclado:(id)sender;
#property (strong, nonatomic) IBOutlet UITextField *inserirTF;
#end
fisrtclass.m
#import "NotasViewController.h"
#import "resultadoViewController.h"
#interface NotasViewController ()
#end
#implementation NotasViewController
#synthesize inserirTF;
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(IBAction)calcular:(id)sender{
float valor = [inserirTF.text floatValue];
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
resultadoViewController *second = [storyboard instantiateViewControllerWithIdentifier:#"resultado"];
second.resultadoFloatValor = valor;
NSLog(#"%.2f", second.resultadoFloatValor);
}
-(IBAction)recuarTeclado:(id)sender{
[sender resignFirstResponder];
}
-(IBAction)clicarFora:(id)sender{
[inserirTF resignFirstResponder];
}
#end
secondclass.h
#import <UIKit/UIKit.h>
#interface resultadoViewController : UIViewController{
float resultadoFloatValor;
}
#property float resultadoFloatValor;
#property (strong, nonatomic) IBOutlet UILabel *resultadoLabelValor;
#property (strong, nonatomic) IBOutlet UILabel *resultadoLabelQtd100;
#end
secondclass.m
#import "resultadoViewController.h"
#interface resultadoViewController ()
#end
#implementation resultadoViewController
#synthesize resultadoFloatValor, resultadoLabelValor, resultadoLabelQtd100;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
NSString *resultadoStringValor = [[NSString alloc] initWithFormat:#"%.2f", resultadoFloatValor];
NSLog(#"%.2f", resultadoFloatValor);
NSLog(#"%#", resultadoStringValor);
resultadoLabelValor.text = resultadoStringValor;
int resultadoIntResto100 = resultadoFloatValor/100;
if (resultadoIntResto100 > 0) {
NSString *resultadoStringQtd100 = [[NSString alloc] initWithFormat:#"%i", resultadoIntResto100];
resultadoLabelQtd100.text = resultadoStringQtd100;
}
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
You'll see 3 NSLogs on my code. For testing, I put 54 on my textfield. The Output was like this:
2013-01-12 21:15:27.020 Divisorreal[21843:c07] 54.00
2013-01-12 21:15:27.023 Divisorreal[21843:c07] 0.00
2013-01-12 21:15:27.023 Divisorreal[21843:c07] 0.00
PS: All my Outlets are correctly connected to the UILabels.

Answer 1

Best guess:
It looks like you are setting resultadoFloatValor after viewDidLoad is called.
Implement prepareForSegue: and set the value there.

Answer 2

Make sure you set the UITextView's delegate to send those actions to your controller.
Try putting a breakpoint in
-(IBAction)calcular:(id)sender
method to ensure its actually being called
