使用版本：依赖Lottie库，1.29.2

// set the text color for unselected state
// 普通状态下的文字属性
NSMutableDictionary *normalAttrs = [NSMutableDictionary dictionary];
normalAttrs[NSForegroundColorAttributeName] = [UIColor cyl_systemGrayColor];
normalAttrs[NSFontAttributeName] = [UIFont fontWithName:@"Helvetica Neue" size:12.0f];

// set the text color for selected state
// 选中状态下的文字属性
NSMutableDictionary *selectedAttrs = [NSMutableDictionary dictionary];
selectedAttrs[NSForegroundColorAttributeName] = [UIColor colorWithRed:0/255.0 green:101/255.0 blue:242/255.0 alpha:1.0];
selectedAttrs[NSFontAttributeName] = [UIFont fontWithName:@"Helvetica Neue" size:12.0f];

selectedAttrs[NSFontAttributeName]加入自定义字体大小后，app切换到后台或切换操作其它app后，重新回到app，字体变成”...“和小红点加了文字的CYLBadgeAnimationTypeBounce和CYLBadgeAnimationTypeShake方法不会动。

还有iOS12
[tabBar setTitlePositionAdjustment:UIOffsetMake(0, -4)];
设置文字位置无效。

从后台或者其他APP返回来后 tabbar上的文字我也会变"..."
