一、前言

iOS开发中，大部分时候我们显示一张静态图就可以了，但是有的时候为了UI表现更生动，我就有可能需要展示gif图来达到效果了。

网上找了一下，显示gif图的框架找到了两个。

SDWebImage

YYImage

二、显示本地gif图

SDWebImage和YYImage的显示本地图片代码。

//load loacle gif image

- (void)loadLocaleGifImage{

//sdwebimage

[self labelFactoryWithFrame:CGRectMake(0, 80, kScreenWidth, 20) title:@"SDWebImage"];

NSString *path = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"gif"];

NSData *gifData = [NSData dataWithContentsOfFile:path];

UIImageView *sdImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 100, kScreenWidth, kScreenHeight/3)];

sdImageView.image = [UIImage sd_animatedGIFWithData:gifData];

[self.view addSubview:sdImageView];

//yyImage show gif image

[self labelFactoryWithFrame:CGRectMake(0, kScreenHeight/2 - 20, kScreenWidth, 20) title:@"yyImage"];

YYImage *yyimage = [YYImage imageNamed:@"test.gif"];

YYAnimatedImageView *yyImageView = [[YYAnimatedImageView alloc] initWithImage:yyimage];

yyImageView.frame = CGRectMake(0, kScreenHeight/2, kScreenWidth, kScreenHeight/3);

[self.view addSubview:yyImageView];

}

三、加载网络的gif图

SDWebImage和YYImage的加载网络图片代码。

//download network gif image

- (void)downloadNetworkGifImage{

//sdwebimage

[self labelFactoryWithFrame:CGRectMake(0, 80, kScreenWidth, 20) title:@"SDWebImage"];

FLAnimatedImageView *sdImageView = [[FLAnimatedImageView alloc] initWithFrame:CGRectMake(0, 100, kScreenWidth, kScreenHeight/3)];

[sdImageView sd_setImageWithURL:[NSURL URLWithString:@"http://photocdn.sohu.com/20151214/mp48444247_1450092561460_10.gif"]];

[self.view addSubview:sdImageView];

//yyImage show gif image

[self labelFactoryWithFrame:CGRectMake(0, kScreenHeight/2 - 20, kScreenWidth, 20) title:@"yyImage"];

YYImage *yyimage = [YYImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://photocdn.sohu.com/20151214/mp48444247_1450092561460_10.gif"]]];

YYAnimatedImageView *yyImageView = [[YYAnimatedImageView alloc] initWithImage:yyimage];

yyImageView.frame = CGRectMake(0, kScreenHeight/2, kScreenWidth, kScreenHeight/3);

[self.view addSubview:yyImageView];

}

- (void)labelFactoryWithFrame:(CGRect)frame title:(NSString *)title{

UILabel *label = [[UILabel alloc] initWithFrame:frame];

label.textAlignment = NSTextAlignmentCenter;

label.textColor = [UIColor blackColor];

label.font = [UIFont systemFontOfSize:14];

label.text = title;

[self.view addSubview:label];

}

四、Podfile文件内容

platform :ios, '10.0'

inhibit_all_warnings!

target 'GifDemo' do

pod 'YYImage'

pod 'SDWebImage/GIF'

pod 'FLAnimatedImage'

end

五、没有demo的文章不是好文章

SDWebImage和YYImage框架显示本地和网络gif图的demo传送门
