IOS几种类型的动画

1.点击按钮,弹出View,再次点击,View回去
创建一个Button,并给button设置一个Bool值,在button的点击事件里写:
- (void)viewBtnAction:(UIButton
*)btn{

if (self.viewbtn.selected)
{

[UIView
animateWithDuration:0.5
animations:^{

self.myView.frame
=
CGRectMake(0,
677,
375,
50);

NSLog(@"===== %@",
NSStringFromCGRect(self.myView.frame));

}];

}else{

//view动画

//参数1:动画时长

[UIView
animateWithDuration:0.5
animations:^{

self.myView.frame =
CGRectMake(0,
577, 375,
50);

NSLog(@"===== %@",NSStringFromCGRect(self.myView.frame));
}];
}

2.点击按钮.弹出View,过几秒,View自动回去
创建一个Button,在button的点击事件里写:
- (void)viewBtnAction:(UIButton
*)btn{
[UIView
animateWithDuration:0.5
animations:^{

self.myView.frame
=
CGRectMake(0,
677,
375,
50);

NSLog(@"===== %@",
NSStringFromCGRect(self.myView.frame));

}];
//delay

延迟几秒执行
[UIView
animateWithDuration:0.5
delay:0.5
options:UIViewAnimationOptionLayoutSubviews
animations:^{

self.myView.frame
=
CGRectMake(0,
667,
375,
50);

}
completion:^(BOOL
finished) {

}];
}

3.键盘上的自定义动画框

//监听键盘弹起
[[NSNotificationCenter
defaultCenter]addObserver:self
selector:@selector(keyboardWillShow:)
name:UIKeyboardWillShowNotification
object:nil];

- (void)keyboardWillShow:(NSNotification
*)notif{

//得到键盘frame,通过键盘frame改变自定义工具栏高度

CGRect frame = [[[notif
userInfo]
objectForKey:UIKeyboardFrameEndUserInfoKey]
CGRectValue];

NSLog(@"frame == %@",
NSStringFromCGRect(frame));

//view动画

//参数1:动画时长

[UIView
animateWithDuration:0.5
animations:^{

self.myView.frame
=
CGRectMake(0,
627
- frame.size.height,
375,
50);

NSLog(@"===== %@",
NSStringFromCGRect(self.myView.frame));

}];
}

4.
Transform动画
创建一个View,和一个按钮,在按钮的点击事件里写
- (void)TransformBtnAction:(UIButton
*)btn{

//transform是View的一个属性,是用来改变View的形态的,通过设置transform属性值可以实现View的形态变化,比如旋转,缩放等

//rotate:旋转的意思 M_PI是180度

// self.myView.transform = CGAffineTransformRotate(self.myView.transform, M_PI_4);

//每次缩放原来的0.9倍

// self.myView.transform = CGAffineTransformScale(self.myView.transform, 0.9, 0.9);

//移动

正数代表往右下方移动,负数代表往左上方移动

self.myView.transform =
CGAffineTransformTranslate(self.myView.transform,
5, 5);
}

5.layer动画
创建一个Button控制,点击旋转,再次点击停止,再点击又继续;在View上添加一张图片,并给图片设置轻拍,可以点击图片控制旋不旋转,并设置Bool值;
在Button的点击事件里写:

- (void)layerBtnAction:(UIButton
*)btn{

//layer层,每个View视图都有一个layer层,使用来设置View上的内容,比如背景颜色,frame,文字等内容,而View只用来负责显示layer层

//我们可以通过改变layer层的内容

//改变view z轴值

CABasicAnimation *animation = [CABasicAnimation
animationWithKeyPath:@"transform.rotation.z"];

//旋转起始值

animation.fromValue
= [NSNumber
numberWithInt:0];

//最终旋转的角度

animation.toValue
= [NSNumber
numberWithInt:M_PI
*
2];

//旋转时间

animation.duration
=
10;

//重复次数,NSIntegerMax为无限旋转

animation.repeatCount
=
NSIntegerMax;

//旋转结束后是否要逆向返回原位置

animation.autoreverses
=
NO;

//是否按照结束位置继续旋转

animation.cumulative
=
YES;

[self.imgV.layer
addAnimation:animation
forKey:@"basicAnimation"];

}
在轻拍事件里写:
- (void)tapImg:(UITapGestureRecognizer
*)tap{

if (self.isSelected) {

//获得上次停止的时间的偏移量

CFTimeInterval stopTime =
self.imgV.layer.timeOffset;

self.imgV.layer.beginTime
=
0;

//设置速度

self.imgV.layer.speed
=
1.0;

//设置偏移量为0

self.imgV.layer.timeOffset
=
0;

//设置开始时间

self.imgV.layer.beginTime
= [self.imgV.layer
convertTime:CACurrentMediaTime()
fromLayer:nil]
- stopTime;

}else{

//每一个view的layer层系统设置记录了一个时间的属性,通过改变view动画时间来控制动画效果

//获得当前旋转的时间点

CFTimeInterval stopTime = [self.imgV.layer
convertTime:CACurrentMediaTime()
fromLayer:nil];

//设置播放速度变成0,即停止

self.imgV.layer.speed
=
0;

self.imgV.layer.timeOffset
= stopTime;

}

self.isSelected
= !self.isSelected;

}

6.长按晃动
在一个View上添加长按手势

UILongPressGestureRecognizer
*longView = [[UILongPressGestureRecognizer
alloc]
initWithTarget:self
action:@selector(longView:)];
[self.myView
addGestureRecognizer:longView];
- (void)longView:(UILongPressGestureRecognizer
*)longTap{

//旋转

CAKeyframeAnimation *keyAnimation = [CAKeyframeAnimation
animationWithKeyPath:@"transform.rotation"];

float top =
M_PI /
18;

float bom = -M_PI
/
18;

keyAnimation.values
=
@[@(top),@(0),@(bom),@(0),@(top)];

keyAnimation.repeatCount
=
NSIntegerMax;

keyAnimation.duration
=
0.3;

[self.myView.layer
addAnimation:keyAnimation
forKey:@"key"];

dispatch_after(dispatch_time(DISPATCH_TIME_NOW,
(int64_t)(4
*
NSEC_PER_SEC)),
dispatch_get_main_queue(), ^{

//停止动画

[self.myView.layer
removeAnimationForKey:@"key"];

});
}

7.关键帧动画:
创建一个按钮,在按钮上放一张没颜色图片,点击按钮,变成另一张带颜色图片,在按钮的点击事件里写:
- (void)zanBtnAction:(UIButton
*)btn{

//关键帧动画

CAKeyframeAnimation *keyAnimation = [CAKeyframeAnimation
animationWithKeyPath:@"transform.scale"];

//设置关键帧的值,values是数组类型

keyAnimation.values
=
@[@(0.1),@(1.0),@(1.5)];

// NSNumber *num = [NSNumber numberWithFloat:0.1];

// keyAnimation.values = [NSArray arrayWithObjects:(nonnull id), ..., nil];

keyAnimation.duration
=
0.3;

[self.zanBtn.layer
addAnimation:keyAnimation
forKey:@"key"];

if (self.zanBtn.isSelected
==
NO) {

[self.zanBtn
setBackgroundImage:[UIImage
imageNamed:@"zan4.jpg"]
forState:UIControlStateNormal];

}else{

[self.zanBtn
setBackgroundImage:[UIImage
imageNamed:@"zan2.jpg"]
forState:UIControlStateNormal];

}

self.zanBtn.selected
= !self.zanBtn.selected;
}
