YYAnimatedImageView

加載GIF，可以暫停和開始
- (void)YYAnimatedImageView {
    animatedImageView = [[YYAnimatedImageView alloc]initWithFrame:CGRectMake(20, 100, 300, 300)];
    [self.view addSubview:animatedImageView];
    YYImage *image = [YYImage imageNamed:@"animalGIF"];
    animatedImageView.image = image;
}
- (void)stop {
    [animatedImageView stopAnimating]; // startAnimating
}

YYCache - 本地存儲數據，類似NSUserDefaults

- (void)YYCache{
    
    // 0.初始化YYCache
    YYCache *cache = [YYCache cacheWithName:@"mydb"];
    
    // 1.緩存普通字符
    [cache setObject:@"我的名字" forKey:@"name"];
    
    // 2.取字符串
    NSString *name = (NSString *)[cache objectForKey:@"name"];
    NSLog(@"name: %@", name);
    
    // 3.刪除
    [cache removeObjectForKey:@"name"];
    
    // 4.是否包含
    [cache containsObjectForKey:@"name"];

}

YYLabel - 設置某個字符串可以點擊

- (void)YYLabel {
    YYLabel *_agressLabel = [[YYLabel alloc]initWithFrame:CGRectMake(0, 100, self.view.frame.size.width - 30, 100)];
    [self.view addSubview:_agressLabel];
    
    NSMutableAttributedString *text  = [[NSMutableAttributedString alloc] initWithString: @"德瑪西亞德瑪西亞德瑪西亞德瑪西亞德瑪西亞德瑪西亞德瑪西亞德瑪西亞德瑪西亞德瑪西亞德瑪西亞德瑪西亞德瑪西亞德瑪西亞德瑪西亞德瑪西亞"];
    text.lineSpacing = 10; // 行間距
    text.font = [UIFont systemFontOfSize:14];
    text.color = [UIColor blackColor];
    [text setTextHighlightRange:NSMakeRange(10, 7) color:[UIColor redColor] backgroundColor:[UIColor clearColor] tapAction:^(UIView * _Nonnull containerView, NSAttributedString * _Nonnull text, NSRange range, CGRect rect) {
        NSLog(@"被點擊了");
    
    }];
    _agressLabel.numberOfLines = 0;  //設置多行顯示
    _agressLabel.preferredMaxLayoutWidth = self.view.frame.size.width - 30; //設置最大的寬度
    _agressLabel.attributedText = text;  //設置富文本
