這是自己沒(méi)事寫(xiě)的小demo，實(shí)現(xiàn)標(biāo)簽根據(jù)標(biāo)簽的文字長(zhǎng)度進(jìn)行流式布局。
效果如下

10行代碼即可實(shí)現(xiàn)，簡(jiǎn)單易懂，廢話(huà)不說(shuō)，上代碼

NSArray *btnTitles = @[@"華潤(rùn)蘇果",@"樂(lè)城",@"柏兆記",@"銀泰城",@"萬(wàn)達(dá)游樂(lè)園",@"皇冠假日酒店",@"霍山大酒店",@"之心城",@"西湖國(guó)際購(gòu)物廣場(chǎng)",@"蘇果超市",@"錦江之星",@"萬(wàn)達(dá)廣場(chǎng)",@"華潤(rùn)五彩城",@"大唐購(gòu)物廣場(chǎng)",@"三孝口",@"合肥南站",@"威斯汀酒店"];
    NSInteger count = [btnTitles count];
    NSLog(@"%ld",count);
    CGFloat  maxX = 15;
    CGFloat row = 0;
    CGFloat maxY = NavigationBarHeight+60;
    for (int i=0; i<count;i++)
    {
        UILabel *lab = [[UILabel alloc]init];
        lab.text = btnTitles[i];
        lab.backgroundColor = [UIColor whiteColor];
        lab.textColor = [UIColor grayColor];
        lab.layer.cornerRadius = 5.0f;
        lab.layer.masksToBounds = YES;
        lab.font = [UIFont systemFontOfSize:14];
        lab.textAlignment = NSTextAlignmentCenter;
        [self.view addSubview:lab];
        
        NSString *str = btnTitles[i];
        CGFloat width = (str.length+2)*15;
        CGFloat height = 30;
        
        if (maxX +width< Screen_Width) {
            lab.frame = CGRectMake(maxX,maxY,width,height);
            maxX = CGRectGetMaxX(lab.frame)+10;
        }
        else
        {
            row ++;
            maxY += 45;
            maxX = 15;
            lab.frame = CGRectMake(maxX,maxY,width,height);
            maxX = CGRectGetMaxX(lab.frame)+10;
        }
    }

代碼就是這樣了，是不是很簡(jiǎn)單？
