Tip：

• 提供高度计算Api
• 自定义标签样式
• 可设置标签控件是否支持单选、多选、不可选三种方式
• 标签点击选择后可执行block回调
• 支持标签的add、insert、remove操作
• 支持异步计算UI布局和UI控件高度

Introduction

• 初始化一个NSMuatbleArray<FHHTag *> *类型的数组tagArray :

NSMuatbleArray<FHHTag *> *tagArray = [[NSMuatbleArray<FHHTag *> alloc] init];
FHHTag *tag = [[FHHTag alloc] initWithTitle:@"Big Hero 6"];
[tagArray addObject:tag];

• 初始化一个FHHTagViewLayout类型的layout：

FHHTagViewLayout *layout = [[FHHTagViewLayout alloc] init];
layout.width = 300;
layout.lineSpacing = 5.0;
layout.innerItemSpacing = 4.0;

• 初始化一个FHHTagViewLayout 类型的tagView，tagView调用 refreshWithTagArray: 即可

FHHTagView *tagView = [[FHHTagView alloc] init];
[tagView refreshWithTagArray:tagArray layout:layout];

                [button setTitleColor:[UIColor purpleColor] forState:UIControlStateNormal];

- (FHHTag *)p_tagWithTitle:(NSString *)title {
    FHHTag *tag = [[FHHTag alloc] initWithTitle:title];
    tag.normalStateButtonBlock = ^(FHHTagButton *button) {
        button.layer.borderColor = [[UIColor blackColor] CGColor];

    tag.cornerRadius = 3;
    tag.borderWidth = 1.0;
    tag.fontSize = 12;
    tag.padding = UIEdgeInsetsMake(5, 5, 5, 5);
//    tag.buttonHeight = 25.0;  // will disable tag.padding
    return tag;
}

异步计算UI布局

// 返回各个按钮标签的CGRect（NSString表示，可以再子线程调用）
+ (NSArray <NSString *> *)tagRectArrayWithTagArray:(nonnull NSArray *)tagArray layout:(nonnull FHHTagViewLayout *)layout;

// 使用上面得到的返回值和layout进行刷新（需要在主线程刷新）
- (void)refreshWithTagArray:(nonnull NSArray *)tagArray tagRectStrArray:(nonnull NSArray<NSString *> *)tagRectStrArray layout:(nonnull FHHTagViewLayout *)layout;

// 根据标签数组和layout计算高度（可以再子线程调用）
+ (CGFloat)heightForTagViewWithTagArray:(nonnull NSArray *)tagArray layout:(nonnull FHHTagViewLayout *)layout;
