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
自定义Button
// 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];
}
点击Button实现两个UIViewController之间的动画切换
-(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];
}
