一、前言
iOS開發中,大部分時候我們顯示一張靜態圖就可以了,但是有的時候為了UI表現更生動,我就有可能需要展示gif圖來達到效果了。
網上找了一下,顯示gif圖的框架找到了兩個。
二、顯示本地gif圖
SDWebImage和YYImage的顯示本地圖片代碼。
//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、加載網絡的gif圖
SDWebImage和YYImage的加載網絡圖片代碼。
//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文件內容
platform :ios, '10.0' inhibit_all_warnings! target 'GifDemo' do pod 'YYImage' pod 'SDWebImage/GIF' pod 'FLAnimatedImage' end
五、沒有demo的文章不是好文章
SDWebImage和YYImage框架顯示本地和網絡gif圖的demo傳送門
