2 つの ViewController を使用して新しいプロジェクトを作成し、ViewController
LTR ではなく右から左にプッシュするクラスをインポートしましたが、それを使用できません。pushViewController
内部で UIRightToLeft.m が呼び出されていないことがわかり、その理由がわかりません。私の主な目標は、それを RTL アニメで動作させることです。
#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
(私の場合、プッシュViewController
で2番目にドラッグされたボタンは1つだけです)ViewController
