APPLE提供了三种storyboard segue的方式:push,modal,custom .
push segue是系统预定义的跳转方式,
为了使其能正常工作,我们还必须加载UINavigationController。
有时候,我们不想看到UINavigation bar,我们可以使用modal segue。
modal segue 的跳转方式有四种:Cover Vertical, Flip Horizontal, Cross Dissolve and Partial Curl。
要是我们想要的跳转方式与这四种方式都不同,我们可以使用自定义跳转方式custom segue。
下面是一个实现custom segue的样例:
1.创建一个UIStoryboardsegue的子类
2.重载-(void)perform 方法
1 - (void) perform
2 {
3 UIViewController *desViewController = (UIViewController *)self.destinationViewController;
4
5 UIView *srcView = [(UIViewController *)self.sourceViewController view];
6 UIView *desView = [desViewController view];
7
8 desView.transform = srcView.transform;
9 desView.bounds = srcView.bounds;
10
11 if(isLandscapeOrientation)
12 {
13 if(isDismiss)
14 {
15 desView.center = CGPointMake(srcView.center.x, srcView.center.y - srcView.frame.size.height);
16 }
17 else
18 {
19 desView.center = CGPointMake(srcView.center.x, srcView.center.y + srcView.frame.size.height);
20 }
21 }
22 else
23 {
24 if(isDismiss)
25 {
26 desView.center = CGPointMake(srcView.center.x - srcView.frame.size.width, srcView.center.y);
27 }
28 else
29 {
30 desView.center = CGPointMake(srcView.center.x + srcView.frame.size.width, srcView.center.y);
31 }
32 }
33
34
35 UIWindow *mainWindow = [[UIApplication sharedApplication].windows objectAtIndex:0];
36 [mainWindow addSubview:desView];
37
38 // slide newView over oldView, then remove oldView
39 [UIView animateWithDuration:0.3
40 animations:^{
41 desView.center = CGPointMake(srcView.center.x, srcView.center.y);
42
43 if(isLandscapeOrientation)
44 {
45 if(isDismiss)
46 {
47 srcView.center = CGPointMake(srcView.center.x, srcView.center.y + srcView.frame.size.height);
48 }
49 else
50 {
51 srcView.center = CGPointMake(srcView.center.x, srcView.center.y - srcView.frame.size.height);
52 }
53 }
54 else
55 {
56 if(isDismiss)
57 {
58 srcView.center = CGPointMake(srcView.center.x + srcView.frame.size.width, srcView.center.y);
59 }
60 else
61 {
62 srcView.center = CGPointMake(srcView.center.x - srcView.frame.size.width, srcView.center.y);
63 }
64 }
65 }
66 completion:^(BOOL finished){
67 //[desView removeFromSuperview];
68 [self.sourceViewController presentModalViewController:desViewController animated:NO];
69 }];70 }
在viewcontroller中,重载prepareforsegue方法
1 - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
2 {
3 HorizontalSlideSegue *s = (HorizontalSlideSegue *)segue;
4 s.isDismiss = NO;
5
6 if (UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation))
7 {
8 s.isLandscapeOrientation = YES;
9 }
10 else
11 {
12 s.isLandscapeOrientation = NO;
13 }14 }
3.选择custom segue 设置segue class为:customsegue(我们自定义的类)
4.使用代码方式调用segue:
