Caanimationgroup Animation Group and catransition transition animations and uiview transitions animation for core animations

1. Animation group, is a subclass of Caanimation, you can save a set of animated objects, after the Caanimationgroup object is added to the layer, all the animation objects in the group can concurrently run

1.1 Property Description:

Animations: A nsarray used to hold a set of animated objects by default, a set of animated objects runs concurrently, or you can change the start time of an animation by setting the BeginTime property of the animated object.

-(void) Touchesbegan: (Nsset<uitouch *> *) touches withevent: (uievent *) event{

[Self rotateanimation];

[Self moveanimation];

Animation Group

Caanimationgroup *group = [Caanimationgroup animation];

Caanimation *animation1 = [self moveanimation];

Caanimation *animation2 = [self rotateanimation];

Group.animations = @[animation1,animation2];

Duration of animation Group

Group.duration = 5;

Group.repeatcount = maxfloat;

[Self.myImageView.layer Addanimation:group Forkey:nil];

}

-(Caanimation *) moveanimation{

1 Animation objects

Cakeyframeanimation *animation = [cakeyframeanimation animationwithkeypath:@ "position"];

Path

Cgmutablepathref path = cgpathcreatemutable ();

Drawing arcs

Cgpathaddarc (Path, NULL, self.view.center.x, self.view.center.y, 0, 2*M_PI, 0);

Animation.path = path;

Animation.duration = 5;

Animation.repeatcount = maxfloat;//infinitely Large

[Self.myImageView.layer addanimation:animation Forkey:nil];

return animation;

}

-(caanimation*) rotateanimation{

1 Animation objects

Cakeyframeanimation *animation = [cakeyframeanimation animationwithkeypath:@ "Transform.rotation.z"];

2

Animation.duration = 0.2;

Animation.repeatcount = maxfloat;

CGFloat angle = M_PI/30;

Animation.values = @[@0,@ (-angle), @0,@ (angle), @0];

[Self.myImageView.layer addanimation:animation Forkey:nil];

return animation;

}

2. Transition animation Catransition is a subclass of caanimation that is used to animate transitions and animate layers to move out of the screen and into the screen. iOS has less transition animations than Mac OS X

Uinavigationcontroller is the animation effect of pushing the controller's view into the screen via catransition

2.1 Animation Properties:
Type: Animation transition types

subtype: Animation transition Direction

startprogress: Start of Animation (percentage in overall animation)

endprogress: End of Animation (percentage in overall animation)

-(void) Viewdidload {

[Super Viewdidload];

index = 0;

Images = [Nsmutablearray arraywithcapacity:6];

for (int i =0; i<6; i++) {

NSString *string = [NSString stringwithformat:@ "%d.jpg", i+1];

UIImage *iamge = [UIImage imagenamed:string];

[Images ADDOBJECT:IAMGE];

}

Self.imageView.image = [UIImage imagenamed:@ "1.jpg"];

self.imageView.userInteractionEnabled = yes;//user interaction

Uiswipegesturerecognizer *swipe = [[Uiswipegesturerecognizer alloc]initwithtarget:self Action: @selector (ChangeImage )];

Swipe.direction = Uiswipegesturerecognizerdirectionleft;

[Self.imageview Addgesturerecognizer:swipe];

}

-(void) changeimage{

index++;

if (index>=6) {

index = 0;

}

Self.imageView.image = [images objectatindex:index];

Transition animations

Catransition *trans = [[Catransition alloc]init];

Property

Fade, ' Movein ', ' push ' and ' reveal

Trans.type = @ "Suckeffect";//Animation type

Trans.duration = 2;

Animation transition Direction

Fromleft ', ' fromright ', ' fromtop ' and Frombottom

Trans.subtype [email protected] "fromright";

[Self.imageView.layer Addanimation:trans Forkey:nil];

}

3.uiview Transitions Animation

+ (void) Transitionwithview: (UIView *) View Duration:    (nstimeinterval) Duration options: (uiviewanimationoptions) Options    animations: (void (^) (void)) animations completion: (void (^) (BOOL    finished)) completion;

Parameter description:

Duration: Duration of animation

View: Views that require a transition animation

Options: Types of transition animations

Animations: Place code that changes the properties of the view in this block

Completion: This block is automatically called after the animation is finished

#import "ViewController.h"

@interface Viewcontroller ()

{

UIView *view1;

UIView *view2;

}

@end

@implementation Viewcontroller

-(void) Viewdidload {

[Super Viewdidload];

View1 = [[UIView alloc]initwithframe:cgrectmake (0, 20, 200, 200)];

View1.backgroundcolor = [Uicolor Redcolor];

[Self.view Addsubview:view1];

View2 = [[UIView alloc]initwithframe:cgrectmake (0, 20, 200, 200)];

View2.backgroundcolor = [Uicolor Greencolor];

[Self.view Addsubview:view2];

Additional setup after loading the view, typically from a nib.

}

-(void) Touchesbegan: (Nsset<uitouch *> *) touches withevent: (uievent *) event{

Single transition animation

/*

[UIView transitionWithView:self.view Duration:2 options:uiviewanimationoptiontransitionflipfromleft animations:^{

Property changes for this view

View2.alpha = 0;

} completion:^ (BOOL finished) {

The call after completion

}];

*/

Dual transition animations

Note When you finish the animation, the Fromview is removed from the parent view

NSLog (@ "Subview before:%@", self.view.subviews);

[UIView transitionfromview:view2 toview:view1 duration:2 Options:uiviewanimationoptiontransitioncurlup Completion : ^ (BOOL finished) {

NSLog (@ "Subview after:%@", self.view.subviews);

}];
