IOS自定义导航栏Push动画效果

创建两个视图控制器，加到导航控制器上

#import "AppDelegate.h"

#import "FirstViewController.h"

@interface AppDelegate ()

@end

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];

    self.window.backgroundColor = [UIColor whiteColor];

    [self.window makeKeyAndVisible];

    

    FirstViewController *firstCtrl = [[FirstViewController alloc] init];

    UINavigationController *navCtrl = [[UINavigationController alloc] initWithRootViewController:firstCtrl];

    self.window.rootViewController = navCtrl;

    

    return YES;

}

在FirstViewController中导入SecondViewController

#import "FirstViewController.h"

#import "SecondViewController.h"

@interface FirstViewController ()

@end

@implementation FirstViewController

- (void)viewDidLoad {

    [super viewDidLoad];

    self.title = @"吃了吗";

    self.view.backgroundColor = [UIColor cyanColor];

    UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

    button.frame = CGRectMake(100, 100, 100, 100);

    [button setTitle:@"push" forState:UIControlStateNormal];

    [button addTarget:self action:@selector(buttonAction) forControlEvents:UIControlEventTouchUpInside];

    [self.view addSubview:button];

}

//转场动画

- (void)transitionPush{

    

    CATransition *tran = [CATransition animation];

    tran.duration = .5;

    

    tran.type = @"pageCurl";

    tran.subtype = kCATransitionFromRight;

    

    [self.navigationController.view.layer addAnimation:tran forKey:nil];

}

//按钮的点击时间，实现push动画效果

- (void)buttonAction{

    [self transitionPush];

    SecondViewController *second = [[SecondViewController alloc] init];

    [self.navigationController pushViewController:second animated:YES];

}

SecondViewController.m中

#import "SecondViewController.h"

@interface SecondViewController ()

@end

@implementation SecondViewController

- (void)viewDidLoad {

    [super viewDidLoad];

    self.title = @"吃的好饱啊";

    self.view.backgroundColor = [UIColor orangeColor];

}
