简单动画的制作,分别用UIImageView的属性animationgImage和定时器NSTimer制作
ViewController的 .h文件
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController
@property (strong,nonatomic) UIImageView *myImageView0;
@property (strong,nonatomic) UIButton *myButton;
@property (strong,nonatomic) NSArray *myArray;
@property (strong,nonatomic) NSTimer *myTimer;
@end
//ViewController的 .m文件
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
//定义两个全局变量
int numble=0
int num=0
- (void)viewDidLoad {
[super viewDidLoad];
self.view.background.Color=[UIColor lightGrayColor];
//创建一个播放动画的视图
self.myImageView0=[[UIImageView alloc]initWithFrame:CGRectMake(65, 50, 280, 280)];
[self.view addSubview:self.myImageView0];
//创建一个按钮，控制动画的播放和停止
self.myButton=[[UIButton alloc]initWithFrame:CGRectMake(160, 350, 80, 40)];
//改变按钮视图的颜色
self.myButton.backgroundColor=[UIColor redColor];
//改变按钮中字体的颜色
[self.myButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
//给按钮Button添加标题
[self.myButton setTitle:@"停止" forState:UIControlStateNormal];
//创建一个储存图画或动画序列帧的数组
//将所有的图画存入数组中
self.myArray=[NSArray arrayWithObjects:[UIImage imageNamed:@"0.png"],[UIImage imageNamed:@"1.png"],[UIImage imageNamed:@"2.png"],[UIImage imageNamed:@"3.png"],[UIImage imageNamed:@"4.png"],[UIImage imageNamed:@"5.png"],[UIImage imageNamed:@"6.png"],[UIImage imageNamed:@"7.png"],[UIImage imageNamed:@"8.png"],[UIImage imageNamed:@"9.png"],[UIImage imageNamed:@"10.png"],[UIImage imageNamed:@"11.png"],[UIImage imageNamed:@"12.png"],[UIImage imageNamed:@"13.png"],[UIImage imageNamed:@"14.png"], nil];
//用UIImageView的属性animationImages
//点击按钮触发是调用方法 suspend
[self.myButton addTarget:self action:@selector(suspend) forControlEvents:UIControlEventTouchUpInside];
//将（序列帧）图画数组赋给UIImageView的animationImages属性
self.myImageView0.animationImages=self.myArray;
//设置播放动画时间，一次动画播放完的时间
self.myImageView0.animationDuration=3;
//设置播放次数，次动画循环播放了多少次
self.myImageView0.animationRepeatCount=10;
//开始播放动画
[self.myImageView0 startAnimating];
//用定时器NSTimer
//定时器，控制调用方法setNextImage，播放动画
self.myTimer=[NSTimer scheduledTimerWithTimeInterval:0.2 target:self selector:@selector(setNextImage) userInfo:nil repeats:YES];
//当按钮Button被触发时调用suspend方法控制定时器的开与关
[self.myButton addTarget:self action:@selector(suspend) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:self.myButton];
}
//按钮控制图画的停止、播放方法
-(void)suspend
{
//用UIImageView的属性animationImages
if (numble%2==0) {
[self.myButton setTitle:@"开始" forState:UIControlStateNormal];
//动画的停止
[self.myImageView0 stopAnimating ];
} else {
[self.myButton setTitle:@"停止" forState:UIControlStateNormal];
//动画的播放
[self.myImageView0 startAnimating ];
}
numble++;
//定时器
if (num%2==0) {
//关闭定时器
[self.myTimer setFireDate:[NSDate distantFuture]];
} else {
//开始定时器
[self.myTimer setFireDate:[NSDate distantPast]];
}
num++;
}
//定时器控制的图片、动画的播放的方法
-(void)setNextImage
{
//numble%15中的15是图片的数量，也就是帧数，你有多少张图片或者多少帧图片，15就写成多少，你也可以设成一个变量，上面的集合也可设成可变的，集合有多少成员就是多少
self.myImageView0.image=[UIImage imageNamed:[NSString stringWithFormat:@"%i.png",numble%15]];
numble++;
}
