ios開發：UINavigationController反方向滑動push

標籤：class   c   ext   a   width   get   

建立個UINavigationController的類別：

#import "UINavigationController+CustomAnimation.h"

@implementation UINavigationController (CustomAnimation)

- (void)customPushViewController:(UIViewController *)viewController

{

    viewController.view.frame = (CGRect){-viewController.view.frame.size.width, 0, viewController.view.frame.size};

    [self.topViewController.viewaddSubview:viewController.view];

    [UIView animateWithDuration:.35f

                     animations:^{

                         viewController.view.frame = (CGRect){0, 0,self.view.bounds.size};

                     }];

}

@end

這種方法是將新的View 加到了self.navigationController.topViewController 上，然後加上了滑動動畫。

使用

- (void)backToHome

{

    [UIView beginAnimations:@"popView"context:NULL];

    [UIView setAnimationDelegate:self];

    [UIView setAnimationDuration:.5f];

    [UIView setAnimationDidStopSelector:@selector(popAnimationDidStop)];

    self.view.frame =CGRectMake(-CGRectGetWidth(self.view.frame), 0,CGRectGetWidth(self.view.frame),CGRectGetHeight(self.view.frame));

    [UIView commitAnimations];

}

可以作為pop的動畫使用
