Xcode 6中的未知类型名称错误

Question

The goal of my app is to calculate two fields that will return in a text box. Unfortunately I'm receiving an error regarding with unknown type field referring to my TotalField.text field. I have two views. One is the home screen which refers to the second view through a button and the second view contains these fields and labels that I'm trying to target.

This is my code.

ViewController.h

//  SalaryCalcApp
//
//

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController
@property (strong, nonatomic) IBOutlet UILabel *Total;
@property (strong, nonatomic) IBOutlet UILabel *HourlyRate;
@property (strong, nonatomic) IBOutlet UILabel *NumberOfHours;
@property (nonatomic, strong) UITextField *TotalField;
@property (nonatomic, strong) UITextField *HourlyRateField;
@property (nonatomic, strong) UITextField *NumberOfHoursField;

@end

ViewController.m

//  SalaryCalcApp
//
// 
//

#import "ViewController.h"

@interface ViewController ()

@end



@implementation ViewController

- (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.
}
@synthesize TotalField;
@synthesize Total;
@synthesize HourlyRate;
@synthesize NumberOfHours;
@synthesize HourlyRateField;
@synthesize NumberOfHoursField;

TotalField.text = [ NSString stringWthFormat:   @"%i", (HourlyRateField.text.intValue * NumberOfHoursField.text.intValue)   ];

@end

The error resides in this code:

TotalField.text = [ NSString stringWthFormat:   @"%i", (HourlyRateField.text.intValue * NumberOfHoursField.text.intValue)];

Error Message:

Unknown type name 'TotalField' and Expected identifier or '('

Thank you everyone for your contributions.

Answer 1

Why is that code not nested inside a function?

Put it inside your viewDidLoad

- (void)viewDidLoad {
    [super viewDidLoad];
     // Do any additional setup after loading the view, typically from a nib.
    TotalField.text = [ NSString stringWthFormat:   @"%i", (HourlyRateField.text.intValue * NumberOfHoursField.text.intValue)   ];

}
