自定义导航栏

1.设置导航栏样式

    [self.navigationBar setBackgroundImage:[UIImage imageNamed:@"navibarbackground"] forBarMetrics:UIBarMetricsDefault];
    [self.navigationBar setTintColor:[UIColor whiteColor]];//BarItem颜色
    NSShadow *shadow = [NSShadow new];
    shadow.shadowColor = [UIColor blackColor];
    shadow.shadowOffset = CGSizeMake(3, 3);
    
    [self.navigationBar  setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor whiteColor],NSFontAttributeName:[UIFont fontWithName:@"AmericanTypewriter"size:23],NSShadowAttributeName:shadow}];

 2.

不想标题栏是光秃秃的文字？您可以通过使用代码行中的图像或标志取代它：

1    self.navigationItem.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"appcoda-logo.png"]];

3.导航栏入栈动画

-(IBAction)pushAction:(id)sender
{
    CATransition *animation = [CATransition animation];
    [animation setDuration:1.3];
    [animation setType:kCATransitionFade]; //淡入淡出
    [animation setSubtype:kCATransitionFromLeft];
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
    SecondViewController *second = [SecondViewController new];
    [self.navigationController pushViewController:second animated:NO];
    [self.navigationController.view.layer addAnimation:animation forKey:nil];
    
}

通过类目为导航栏添加动画的方法

#import "UINavigationController+CustomPushOrPop.h"

@implementation UINavigationController (CustomPushOrPop)

-(void)customPushViewContrller:(UIViewController *)viewContrller
{
    viewContrller.view.frame = CGRectMake(0,-viewContrller.view.frame.size.height, self.view.frame.size.width, self.view.frame.size.height);
    [self pushViewController:viewContrller animated:NO];
    [UIView animateWithDuration:0.35f animations:^
    {
        viewContrller.view.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
    }
    completion:^(BOOL finished)
    {
        
    }];
}
