ABSegmentView

如果每个产品设计都能根据苹果的UI风格来的话,那就省事很多了,但是现实是残酷的,而且如果都用一套苹果原生UI的,恩,看起来也很蛋疼。每个app打开都一个鸟UI,恩,也会视觉疲劳。因此就必须自定义各种各样的UI控件来满足产品UI需求。 今天分享一个自己产品UI需求效果的分段控制器。因为系统的UISegmentedControl局限性,很多效果没法实现,只能自定义,纵观各种app,基本上难看到原生的UISegmentedControl。 先看下效果图 这个自定义SegmentView除了基本的标题选择、底部滚动条等,还支持小红点提醒。实现也很简单,当然也可以根据业务需求,自己慢慢增加功能。具体看代码:

#import <UIKit/UIKit.h>

@class ABSegmentStyle;

@interface ABSegmentStyle : NSObject

/** 滚动条的颜色 */
@property (nonatomic, strong) UIColor *bottomLineColor;
/** 滚动条的高度 默认为2 */
@property (assign, nonatomic) CGFloat bottomLineHeight;
/** 标题的字体 默认为17 */
@property (strong, nonatomic) UIFont *titleFont;
/** 标题一般状态的颜色 */
@property (strong, nonatomic) UIColor *normalTitleColor;
/** 标题选中状态的颜色 */
@property (strong, nonatomic) UIColor *selectedTitleColor;
/** 隐藏底部边框线,默认YES */
@property (assign, nonatomic) BOOL hiddenBottomBorderLine;

@end


typedef void(^TitleBtnOnClickBlock)(NSString *title, NSInteger index);

@interface ABSegmentView : UIView

-(instancetype)initWithFrame:(CGRect)frame segmentStyle:(ABSegmentStyle *)segmentStyle titles:(NSArray<NSString *> *)titles titleDidClick:(TitleBtnOnClickBlock)titleDidClick;

@property (nonatomic, assign, readonly) NSInteger selectedIndex;

/**
 设置选中的下标

 @param index 下标
 @param animated 动画
 */
- (void)setSelectedIndex:(NSInteger)index animated:(BOOL)animated;

/**
 根据外部滚动视图来调整底部横线位置

 @param scrollView 外部滚动视图
 */
- (void)adjustScollViewDidScroll:(UIScrollView *)scrollView;

/**
 显示小红点

 @param index 位置
 */
- (void)showBaggeOnItemIndex:(NSInteger)index;

/**
 隐藏小红点
 
 @param index 位置
 */
- (void)hideBaggeOnItemIndex:(NSInteger)index;

@end

使用初始化也很简单:

    ABSegmentStyle *style = [[ABSegmentStyle alloc]init];
    style.titleFont = [UIFont boldSystemFontOfSize:17];

    YTWeakSelf(self);
    ABSegmentView *segmentView = [[ABSegmentView alloc]initWithFrame:CGRectMake(0, 0, kWidthValue(225), 44) segmentStyle:style titles:@[YTLocalizedString(@"跑步"),YTLocalizedString(@"自行车"),YTLocalizedString(@"铁三")] titleDidClick:^(NSString *title, NSInteger index) {
        if (weakself.scrollview) {
            [weakself.scrollview setContentOffset:CGPointMake(weakself.scrollview.frame.size.width * index, 0) animated:NO];
            [weakself scrollViewDidEndScrollingAnimation:weakself.scrollview];
            weakself.scrollview.scrollEnabled = YES;
        }
    }];
    self.navigationItem.titleView = segmentView;
    self.segmentView = segmentView;
    [segmentView setSelectedIndex:1 animated:NO];
- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
    CGFloat pageWidth = scrollView.frame.size.width;
    NSInteger page = scrollView.contentOffset.x / pageWidth;
    [self scrollViewDidEndScrollingAnimation:scrollView];
    
    [self.segmentView setSelectedIndex:page animated:YES];
}

-(void)scrollViewDidScroll:(UIScrollView *)scrollView
{
    [self.segmentView adjustScollViewDidScroll:scrollView];
}
