[课堂实践与项目]两种方法实现视图之间的动画效果

1.使用不用加载包的视图 

1、commitAnimations方式使用UIView动画

- (void)changeToYellowView

{

    

    LCYellowViewController *yellowViewController = [[LCYellowViewController alloc]initWithNibName:@"YellowView" bundle:nil];

    [self.view addSubview:yellowViewController.view];

    

   

    

    [UIView beginAnimations:@"animation" context:nil];

    [UIView setAnimationDuration:8];

    [UIView setAnimationCurve:UIViewAnimationCurveEaseOut];

    [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES];

     [self.view exchangeSubviewAtIndex:0 withSubviewAtIndex:1];

    

    

    [UIView commitAnimations];

    

    

    [yellowViewController release];

}

2.导入包

#import <QuartzCore/QuartzCore.h> //需要添加包

 实现动画效果

使用：CATransition

- (void)changeToYellowView
{
    
    LCYellowViewController *yellowViewController = [[LCYellowViewController alloc]initWithNibName:@"YellowView" bundle:nil];

    [self.view addSubview:yellowViewController.view];
    
    CATransition *transition = [CATransition animation];
    transition.duration = 7;
    transition.type = kCATransitionMoveIn;
    transition.subtype = kCATransitionFromTop;
    
    [self.view exchangeSubviewAtIndex:0 withSubviewAtIndex:1];
    
    [self.view.layer addAnimation:transition forKey:@"animation"];
    

    [yellowViewController release];
}
