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

GitHub下载地址:https://github.com/Split82/HMGLTransitions

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]; }

#pragma mark - #pragma mark ModalController delegate   - (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

// custom 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]; }
