1.系統UIImageView 多張圖片組成動畫
/** * UIImageView 動畫 * Memory-23M */ -(void)gifPlay1 { // NSArray *array=@[@"image0.png",@"image1.png",@"image2.png"]; // UIImageView *imgview= [UIImageView imageViewAnimation:CGRectMake(50,80, 550/2, 200) imageNames:array duration:1]; UIImageView* animatedImageView = [[UIImageView alloc] initWithFrame:CGRectMake(50,80, 550/2, 200)]; animatedImageView.animationImages =@[[UIImage imageNamed:@"image0"], [UIImage imageNamed:@"image1"], [UIImage imageNamed:@"image2"], ]; animatedImageView.animationDuration = 1.0f; animatedImageView.animationRepeatCount = 0; [self.view addSubview: animatedImageView]; [animatedImageView startAnimating]; }
2.利用第三方庫
1)IImageView-PlayGIF YFGIFImageView
/** * UIImageView-PlayGIF 是 UIImageView 子類,用來顯示 GIF。UIIMageView-PlayGIF 性能高,而且占用的內存很低。 * https://github.com/yfme/UIImageView-PlayGIF * Memory-21.9M * #import "YFGIFImageView.h" */ -(void)gifPlay2 { NSString *gifPath=[[NSBundle mainBundle] pathForResource:@"test" ofType:@"gif"]; YFGIFImageView *gifview=[[YFGIFImageView alloc]init]; gifview.backgroundColor=[UIColor clearColor]; gifview.gifPath=gifPath; gifview.frame=CGRectMake(50, 100,550/2, 200); [self.view addSubview:gifview]; [gifview startGIF]; }
2)SCGIFImageView
/** * 摘要: SCGIFImageView是一個開源的GIF圖片動畫顯示控件,通過將GIF的每一幀都取出來生成UIImage對象存放在一個數組中,然后使用NSTimer進行動畫輪轉。 * https://github.com/shichangone/SCGifExample * Memory-22.5M * #import "SCGIFImageView.h" */ -(void)gifPlay3 { NSString* filePath = [[NSBundle mainBundle] pathForResource:@"test.gif" ofType:nil]; NSData* imageData = [NSData dataWithContentsOfFile:filePath]; SCGIFImageView* gifImageView = [[SCGIFImageView alloc]init]; [gifImageView setData:imageData]; gifImageView.frame = CGRectMake(50,100, gifImageView.image.size.width, gifImageView.image.size.height); [self.view addSubview:gifImageView]; }
3)YLGIFImage
/** * YLGIFImage 是異步 GIF 圖像解碼器和圖像查看器,支持播放 GIF 圖像,而且使用很少的內存。 * https://github.com/liyong03/YLGIFImage * Memory-22.7M * #import "YLImageView.h" * #import "YLGIFImage.h" */ -(void)gifPlay5 { YLImageView* imageView = [[YLImageView alloc] initWithFrame:CGRectMake(0, 160, 320, 240)]; [self.view addSubview:imageView]; imageView.image = [YLGIFImage imageNamed:@"test.gif"]; }
4)SDWebImageView里的UIImage+GIF
提供接口:
+ (UIImage *)sd_animatedGIFNamed:(NSString *)name;
+ (UIImage *)sd_animatedGIFWithData:(NSData *)data;
- (UIImage *)sd_animatedImageByScalingAndCroppingToSize:(CGSize)size;
/** * 利用SDWebImageView 庫播放gif * Memory-22.6M * #import "UIImage+GIF.h" */ -(void)gifPlay6 { UIImage *image=[UIImage sd_animatedGIFNamed:@"test"]; UIImageView *gifview=[[UIImageView alloc]initWithFrame:CGRectMake(50,80,image.size.width, image.size.height)]; gifview.backgroundColor=[UIColor orangeColor]; gifview.image=image; [self.view addSubview:gifview]; }
為MBProgressHUD 添加加載動畫
/** * MBProgressHUD 添加加載動畫 * Memory-23.8M * #import "UIImage+GIF.h" * #import "MBProgressHUD.h" */ -(void)gifPlay6 { UIImage *image=[UIImage sd_animatedGIFNamed:@"test"]; UIImageView *gifview=[[UIImageView alloc]initWithFrame:CGRectMake(0,0,image.size.width/2, image.size.height/2)]; gifview.image=image; MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES]; hud.color=[UIColor grayColor];//默認顏色太深了 hud.mode = MBProgressHUDModeCustomView; hud.labelText = @"加載中..."; hud.customView=gifview; }
其它
微博客戶端 VVebo 的作者開源了他自己為VVebo寫的GIF解決方案 VVeboImageView, 占用內存很小。(iOS移動開發周報-第4期)
