UI动画练习 - CABasicAnimation：视图绕X/Y轴旋转（3D效果）

视图 3D 旋转

1 - 代码示例：以绕 X 轴旋转为例

 1 #import "ViewController.h"
 2 @interface ViewController ()
 3 @property(strong,nonatomic)UIImageView *logoIV;
 4
 5 @end
 6
 7 @implementation ViewController
 8
 9 - (void)viewDidLoad {
10     [super viewDidLoad];
11     self.view.backgroundColor = [UIColor whiteColor];
12
13     // 视图
14     self.logoIV = [[UIImageView alloc] initWithFrame:CGRectMake(60, 200, self.view.frame.size.width - 120, self.view.frame.size.width - 120)];
15     self.logoIV.backgroundColor = [UIColor yellowColor];
16     [self.view addSubview:_logoIV];
17
18     // 动画配置
19     CABasicAnimation *rotationAnimation;
20     // transform.rotation.y 环 Y 轴立体旋转
21     rotationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.x"];// 绕 X 轴立体旋转
22     rotationAnimation.toValue = [NSNumber numberWithFloat: M_PI * 2.0 ];
23     rotationAnimation.duration = 3;
24     rotationAnimation.cumulative = YES;
25     rotationAnimation.repeatCount = MAXFLOAT;
26
27     rotationAnimation.removedOnCompletion = NO; // 防止程序 前后台切换后动画静止
28     [self.logoIV.layer addAnimation:rotationAnimation forKey:@"rotationAnimation"];
29     self.logoIV.layer.shadowOpacity = 1; // 阴影透明度
30     self.logoIV.layer.shadowColor = [UIColor blueColor].CGColor;  // 阴影颜色
31     self.logoIV.layer.shadowRadius = 50; // 阴影半径
32     self.logoIV.layer.cornerRadius = (self.view.frame.size.width - 120)*0.5;
33     self.logoIV.layer.borderColor = [UIColor greenColor].CGColor; // 边框颜色
34     self.logoIV.layer.borderWidth = 20;  // 边框半径
35
36 }
