Question

두 개의 ViewController로 새 프로젝트를 만들고 LTC 대신 오른쪽에서 왼쪽으로 ViewController을 푸시하는 클래스를 가져 왔지만이를 사용할 수는 없습니다. UIRightToLeft.m 내부의 pushViewController이 호출되지 않고 그 이유를 알 수 없습니다. 내 목표는 RTL 언어로 작업하도록하는 것입니다.

#import "UIRightToLeft.h" 

@implementation UIRightToLeft 

- (id)initWithRootViewController:(UIViewController *)rootViewController 
{ 
    self = [super initWithRootViewController:rootViewController]; 
    if (!self) 
     return nil; 
    return self; 
} 

- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated 
{ 
    NSLog(@"pushViewController"); 
    // Add the viewController and a fake controller without animation. Then pop the fake controller with animation. 
    UIViewController *fakeController = [[UIViewController alloc] init] ; 
    [super setViewControllers:[[self viewControllers] arrayByAddingObjectsFromArray:[NSArray arrayWithObjects:viewController, fakeController, nil]] animated:NO]; 
    [super popViewControllerAnimated:animated]; 
} 

- (void)popViewControllerAnimatedStep2:(UIViewController *)viewController 
{ 
    // Push the new top controller with animation 
    [super pushViewController:viewController animated:YES]; 
    // Remove the view that should have been popped 
    NSMutableArray *arr = [NSMutableArray arrayWithArray:[self viewControllers]]; 
    [arr removeObjectAtIndex:[[self viewControllers] count]-2]; 
    [super setViewControllers:[NSArray arrayWithArray:arr] animated:NO]; 
} 

- (UIViewController *)popViewControllerAnimated:(BOOL)animated 
{ 
    NSLog(@"popViewControllerAnimated"); 

    if (animated) 
    { 
     // Save the controller that should be on top after this pop operation 
     UIViewController *newTopController = [[self viewControllers] objectAtIndex:[[self viewControllers] count]-2]; 
     // Remove it from the stack. Leave the view that should be popped on top 
     NSMutableArray *arr = [NSMutableArray arrayWithArray:[self viewControllers]]; 
     [arr removeObjectAtIndex:[[self viewControllers] count]-2]; 
     [super setViewControllers:[NSArray arrayWithArray:arr] animated:NO]; 
     // Schedule the next step 
     [self performSelector:@selector(popViewControllerAnimatedStep2:) withObject:newTopController afterDelay:0]; 
     return [arr objectAtIndex:[arr count]-1]; 
    } 
    return [super popViewControllerAnimated:NO]; 
} 

@end 

ViewController.m :

#import "ViewController.h" 
#import "UIRightToLeft.h" 
#import "SecondViewController.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. 
} 

- (IBAction)pressMe:(UIButton *)sender { 
    SecondViewController *next = [[SecondViewController alloc]init]; 
    [self.navigationController pushViewController:next animated:YES];  
} 

@end 

ViewController.h :

#import <UIKit/UIKit.h> 

@interface ViewController : UIViewController 
- (IBAction)pressMe:(UIButton *)sender; 

@end 

(푸시와 두 번째 ViewController에 draged 단 하나 개의 버튼을 거기에 내 ViewController에서)

오류 로그를보고 나면 실제로 네비게이션 컨트롤러의 하위 클래스 UIRightToLeft가 필요하다고 생각합니다.

스토리 보드를 사용하는 경우 네비게이션 컨트롤러를 선택하고 사용자 지정 클래스를 UIRightToLeft로 설정하십시오.
