转场动画是针对view图层的动画
#import "DYViewController.h"
@interface DYViewController ()
@property (weak, nonatomic) IBOutlet UIImageView *imageView;
@property (nonatomic, assign) int index;
@end
@implementation DYViewController
- (void)viewDidLoad
{
[super viewDidLoad];
_index = 1;
}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
_index++;
if (_index == 10) {
_index = 1;
}
NSString *fileName = [NSString stringWithFormat:@"%d",_index];
_imageView.image = [UIImage imageNamed:fileName];
CATransition *anim = [CATransition animation];
anim.type = @"pageCurl";
anim.subtype = kCATransitionFromLeft;
anim.startProgress = 0.5;
anim.duration = 2;
[_imageView.layer addAnimation:anim forKey:nil];
}视图控制器直接切换动画
只需要在window的layer上添加转场动画即可实现
@interface KKTestController ()
@end
@implementation KKTestController
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor redColor];
UIButton *btn = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];
btn.backgroundColor = [UIColor yellowColor ];
[btn addTarget:self action:@selector(testA:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];
}
-(void)testA:(id)sender {
KKTabBarController *test = [[KKTabBarController alloc] init];
CATransition *anim = [CATransition animation];
anim.type = @"oglFlip";
anim.subtype = kCATransitionFromRight;
anim.duration = 2;
UIWindow *window = [UIApplication sharedApplication].keyWindow;
[window.layer addAnimation:anim forKey:nil];
window.rootViewController = test;
}属性解析:
type：动画过渡类型
subtype：动画过渡方向
startProgress：动画起点(在整体动画的百分比)
endProgress：动画终点(在整体动画的百分比)/*type属性 过渡效果
fade //交叉淡化过渡(不支持过渡方向) kCATransitionFade
push //新视图把旧视图推出去 kCATransitionPush
moveIn //新视图移到旧视图上面 kCATransitionMoveIn
reveal //将旧视图移开,显示下面的新视图 kCATransitionReveal
cube //立方体翻滚效果
oglFlip //上下左右翻转效果
suckEffect //收缩效果，如一块布被抽走(不支持过渡方向)
rippleEffect //滴水效果(不支持过渡方向)
pageCurl //向上翻页效果
pageUnCurl //向下翻页效果
cameraIrisHollowOpen //相机镜头打开效果(不支持过渡方向)
cameraIrisHollowClose //相机镜头关上效果(不支持过渡方向)

/*subtype 过渡方向
