APIs

Methods

- (instancetype)initWithTitles:(NSArray <NSString *> *)titles;
- (instancetype)initWithImages:(NSArray <UIImage *> *)images;
- (instancetype)initWithImages:(NSArray <UIImage *> *)images
                selectedImages:(nullable NSArray <UIImage *> *)selectedImages;

You can use selectedImages if you want to show different images when a specific segment selected.

- (nullable NSString *)titleAtIndex:(NSUInteger)index;
- (nullable UIImage *)imageAtIndex:(NSUInteger)index;

You can get the corresponding text or image based on a specific index.

- (void)showBadgeAtIndexes:(NSArray <NSNumber *> *)indexes;
- (void)hideBadgeAtIndex:(NSUInteger)index;

example:

[segmentedControl show BadgeAtIndexes:@[@1, @2]];

- (void)setTextAttributes:(nullable NSDictionary *)attributes 
                 forState:(YUSegmentedControlState)state;

The attributes for text. For a list of attributes that you can include in this dictionary, see Character Attributes. The value of state could be YUSegmentedControlNormal and YUSegmentedControlSelected.

example:

[segmentedControl setTextAttributes:@{
  NSFontAttributeName: [UIFont systemFontOfSize:20.0 weight:UIFontWeightLight],
  NSForegroundColorAttributeName: [UIColor blackColor]
} forState:YUSegmentedControlNormal];
