setValue: forUndefinedKey: этот класс не совместим со значением ключа для ключа [duplicate]
На этот вопрос уже есть ответ здесь:
Что это значит? «NSUnknownKeyException», причина:… этот класс не совместим со значением ключа для кода X » 66 ответовЯ создаю логин для просмотра заявок в службу поддержки. Первый вид - это вид тикета, и, если вы не вошли в систему, вы попадете на экран входа в систему. Однако я получаю это:
Поддержка [3209: 18e03]* Завершение работы приложения из-за необработанного исключения «NSUnknownKeyException», причина: «[setValue: forUndefinedKey:]: этот класс не соответствует значению ключа, соответствующему кодированию для ключа LoginScreen». *

Вот мой код для LoginScreen.m
#import "UIAlertView+error.h"
#import "LoginScreen.h"
#import "API.h"
#include <CommonCrypto/CommonDigest.h>
#define sayWhat @"REMOVEDFORSECURITY"
@implementation LoginScreen
-(void)viewDidLoad {
NSLog(@"Found me!");
[super viewDidLoad];
//focus on the username field /show keyboard
[fldUsername becomeFirstResponder];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
-(IBA
ction)btnLoginRegisterTapped:(UIButton*)sender {
if (fldUsername.text.length < 4 || fldPassword.text.length < 4){
[UIAlertView error:@"Enter username and password over 4 chars each."];
return;
}
//very basic encryption called "salting"
NSString* saltedPassword = [NSString stringWithFormat:@"%@%@", fldPassword.text, sayWhat];
//prep the hashed storage
NSString* hashedPassword = nil;
unsigned char hashedPasswordData[CC_SHA1_DIGEST_LENGTH];
//actually hash this
NSData *data = [saltedPassword dataUsingEncoding: NSUTF8StringEncoding];
if (CC_SHA1([data bytes], [data length], hashedPasswordData)){
hashedPassword = [[NSString alloc] initWithBytes:hashedPasswordData length:sizeof(hashedPasswordData) encoding:NSASCIIStringEncoding];
} else {
[UIAlertView error:@"Password can't be sent"];
return;
}
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
fldUsername.text, @"username",
hashedPassword, @"password", nil];
//here is the web call finally!
[[API sharedInstance] commandWithParams:params
onCompletion:^(NSDictionary *json){
//returned result
NSDictionary* res = [[json objectForKey:@"result"] objectAtIndex:0];
if([json objectForKey:@"error"]==nil && [[res objectForKey:@"userid"] intValue]> 0) {
//success
} else {
//error'
[UIAlertView error:[json objectForKey:@"error"]];
}
}];
}

и LoginScreen.h
#import <UIKit/UIKit.h>
@interface LoginScreen : UIViewController {
//the login form fields
IBOutlet UITextField* fldUsername;
IBOutlet UITextField* fldPassword;
}
//action for when either button is pressed
