HMGLTransitions 是一套动画演示两个UIView 或 UIViewController之间切换时的过渡效果;

有些情况下我们需要两个视图之间做一个动画过渡的切换,或许系统自带的CATransition和普通动画难以满足我们的需求,此时第三方类库就是一个不错的选择;HMGLTransitions提供五种不错效果,分别是: 3D Right(letf) 、Cloth、Flip right(letf)、Rotate和Doors
以上是GitHub上下载自带的Demo展示的五种效果图,展示了两个UIView 和 两个UIViewController各自之间动画切换(截图中仅展示两个view之间切换),工程目录结构:
HMGLTransitions目录下是这个第三方类库所有文件,Transitions文件下是五种动画的实现类,你需要那种动画就需要把那种动画头文件包含进去
- - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
- if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) {
- Switch3DTransition *t1 = [[[Switch3DTransition alloc] init] autorelease];
- t1.transitionType = Switch3DTransitionLeft;
- FlipTransition *t2 = [[[FlipTransition alloc] init] autorelease];
- t2.transitionType = FlipTransitionRight;
- transitionsArray = [[NSArray alloc] initWithObjects:
- [[[Switch3DTransition alloc] init] autorelease],
- t1,[[[ClothTransition alloc] init] autorelease],
- [[[FlipTransition alloc] init] autorelease],
- t2,
- [[[RotateTransition alloc] init] autorelease],
- [[[DoorsTransition alloc] init] autorelease],
- nil];
- transitionsNamesArray = [[NSArray alloc] initWithObjects:
- @"Switch 3D right",
- @"Switch 3D left",
- @"Cloth",
- @"Flip left",
- @"Flip right",
- @"Rotate",
- @"Doors",
- nil];
- self.transition = [transitionsArray objectAtIndex:0];
- }
- return self;
- }
初始化视图,并把这五种动画效果存放在 transitionsArray数组之中,Switch3DTransition默认向右,FlipTransition默认向左,分别定义了一个t1对象和t2对象,设置t1.transitionType = Switch3DTransitionLeft; t2.transitionType = FlipTransitionRight; 所以transitionsArray存放的是7种效果,对应transitionsNamesArray数组中关于动画其中效果的名字,显示在视图上的UITableViewCell上;两个数组是一一对应的关系;
两个UIView之间的动画过渡切换实现方法
- //从View1切换到View2
- - (void)switchToView2 {
- UIView *containerView = view1.superview;
- [[HMGLTransitionManager sharedTransitionManager] setTransition:transition];
- [[HMGLTransitionManager sharedTransitionManager] beginTransition:containerView];
- // Here you can do whatever you want except changing position, size or transformation of container view, or removing it from view hierarchy.
- view2.frame = view1.frame;
- [view1 removeFromSuperview];
- [containerView addSubview:view2];
- [[HMGLTransitionManager sharedTransitionManager] commitTransition];
- }
- //从View2切换到View1
- - (void)switchToView1 {
- UIView *containerView = view2.superview;
- // Set transition
- [[HMGLTransitionManager sharedTransitionManager] setTransition:transition];
- [[HMGLTransitionManager sharedTransitionManager] beginTransition:containerView];
- // Here you can do whatever you want except changing position, size or transformation of container view, or removing it from view hierarchy.
- view1.frame = view2.frame;
- [view2 removeFromSuperview];
- [containerView addSubview:view1];
- // Commit transition
- [[HMGLTransitionManager sharedTransitionManager] commitTransition];
- }
- - (void)modalControllerDidFinish:(ModalViewController *)modalController {
- [[HMGLTransitionManager sharedTransitionManager] setTransition:transition];
- [[HMGLTransitionManager sharedTransitionManager] dismissModalViewController:modalController];
- }
ModalviewController类中定义一个ModalControllerDelegate协议,定义协议方法- (void)modalControllerDidFinish:(ModalViewController*)modalController;实现两个View之间的传值,也就是当我们在UITableViewCell对象上现则哪中过渡效果是的时候,传递HMGLTransition对象transition;
[HMGLTransitionManager sharedTransitionManager]使用了单例设计模式
实现两个UIViewController之间的动画切换方法
- - (IBAction)viewTransitionButtonPressed:(id)sender {
- UIButton *button = (UIButton*)sender;
- // view transition to view1 or view2 depending on actual view
- if (button.superview == view1) {
- [self switchToView2];
- }
- else {
- [self switchToView1];
- }
- }
- - (IBAction)modalPresentationButtonPressed:(id)sender {
- [[HMGLTransitionManager sharedTransitionManager] setTransition:transition];
- ModalViewController *newController;
- if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
- newController = [[ModalViewController alloc] initWithNibName:@"ModalViewController-iPad" bundle:nil];
- }
- else {
- newController = [[ModalViewController alloc] initWithNibName:@"ModalViewController" bundle:nil];
- }
- newController.delegate = self;
- [[HMGLTransitionManager sharedTransitionManager] presentModalViewController:newController onViewController:self];
- [newController release];
- }
演示一个Demo:
1.新建一个Single View Application模板工程,命名RollingView,将下载下来的工程中里HMGLTransitions文件夹拷贝加入到你的工程目录中,然后添加 QuartzCore.framework 和 OpenGLES.framework 库
2. File->New->File 添加一个控制器类ViewController2,在ViewController.h中包含头文件
- // ViewController.h
- #import <UIKit/UIKit.h>
- #import "Switch3DTransition.h"
- #import "FlipTransition.h"
- #import "RotateTransition.h"
- #import "ClothTransition.h"
- #import "DoorsTransition.h"
- #import "ViewController2.h"
- #import "HMGLTransitionManager.h"
- @interface ViewController : UIViewController
- {
- UIButton *startBtn;
- HMGLTransition *transition;
- }
- @end
在ViewController.m中
自定义Button- - (UIButton *)buttonWithFrame:(CGRect)frame withNormalTitle:(NSString *)title withOtherStateTitle:(NSString *)otherTitle action:(SEL)action
- {
- UIImage *buttonBackgroundImage = [[UIImage imageNamed:@"button_background.png"] stretchableImageWithLeftCapWidth:5 topCapHeight:5];
- UIImage *disabledButtonBackgroundImage = [[UIImage imageNamed:@"button_background_disabled.png"] stretchableImageWithLeftCapWidth:5 topCapHeight:5];
- UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
- button.frame = frame;
- [button setTitle:title forState:UIControlStateNormal];
- [button setTitle:otherTitle forState:UIControlStateDisabled];
- [button setBackgroundImage:buttonBackgroundImage forState:UIControlStateNormal];
- [button setBackgroundImage:disabledButtonBackgroundImage forState:UIControlStateDisabled];
- [button setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
- [button setTitleColor:[UIColor grayColor] forState:UIControlStateDisabled];
- [button addTarget:self action:action forControlEvents:UIControlEventTouchUpInside];
- [self.view addSubview:button];
- return button;
- }
- - (void)viewDidLoad
- {
- [super viewDidLoad];
- CGRect butRect = CGRectMake(self.view.bounds.origin.x + 60, self.view.bounds.origin.y + 100, self.view.frame.size.width-60-60, 100);
- startBtn= [self buttonWithFrame:butRect withNormalTitle:@"View 1" withOtherStateTitle:@"View 1" action:@selector(startView:)];
- Switch3DTransition *tran = [[[Switch3DTransition alloc] init] autorelease];
- tran.transitionType = Switch3DTransitionLeft;
- transitionArr = [[NSArray alloc] initWithObjects:[[[DoorsTransition alloc] init] autorelease], nil];
- self.transition = [transitionArr objectAtIndex:0];
- [HMGLTransitionManager sharedTransitionManager];
- }
- -(void)startView:(id)sender
- {
- [[HMGLTransitionManager sharedTransitionManager] setTransition:transition];
- ViewController2 *vc2 = [[ViewController2 alloc] initWithNibName:@"ViewController2" bundle:nil];
- [[HMGLTransitionManager sharedTransitionManager] presentModalViewController:vc2 onViewController:self];
- }
在ViewController2类中,方法实现基本类似
- - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
- {
- self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
- if (self) {
- FlipTransition *tran = [[[FlipTransition alloc] init] autorelease];
- tran.transitionType = FlipTransitionLeft;
- transitionArr = [[NSArray alloc] initWithObjects:[[[FlipTransition alloc] init] autorelease], nil];
- self.transition = [transitionArr objectAtIndex:0];
- }
- return self;
- }
- - (void)viewDidLoad
- {
- [super viewDidLoad];
- CGRect butRect;
- if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
- butRect = CGRectMake(self.view.bounds.origin.x + 60, self.view.bounds.origin.y + 100, 768-60-60, 100);
- }
- else {
- butRect = CGRectMake(self.view.bounds.origin.x + 60, self.view.bounds.origin.y + 100, self.view.frame.size.width-60-60, 100);
- }
- endBtn= [self buttonWithFrame:butRect withNormalTitle:@"View 2" withOtherStateTitle:@"View 2" action:@selector(endView:)];
- }
- -(void)endView:(id)sender
- {
- [[HMGLTransitionManager sharedTransitionManager] setTransition:transition];
- ViewController *vc1;
- if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
- vc1 = [[ViewController alloc] initWithNibName:@"ViewController_iPad" bundle:nil];
- }
- else {
- vc1 = [[ViewController alloc] initWithNibName:@"ViewController_iPhone" bundle:nil];
- }
- [[HMGLTransitionManager sharedTransitionManager] presentModalViewController:vc1 onViewController:self];
- }
