横向排列views,自动换行

有时候碰见两行一样的按钮, 不想用collectionView,一个个写是更不可能的了,所以for循环创建完之后用这个方法排列一下搞定

/** 排列view,横向间隔自动计算 @param views 要排列的views @param width 总宽度 @param column 列数(每行几个) @param origin 起始点(第一个view起始点) @param verDistance views纵向间隔(行间距) */- (void)arrangeViews:(NSArray *)views      superviewWidth:(float)width              column:(int)column              origin:(CGPoint)origin    verticalDistance:(float)verDistance{    for (int i = 0; i < views.count; i++) {        UIView *view = views[i];        //起始x 两个x的差 列:i%column        view.x = origin.x + i%column * (width-2*origin.x-view.width)/(column-1);        //起始y 两个y的差 行:i/column        view.y = origin.y + i/column * (view.height+verDistance);    }}

/** 排列view,固定间隔,自动计算列数 @param views 要排列的views @param width 总宽度 @param origin 起始点(第一个view起始点) @param distance 间距 */- (void)arrangeViews:(NSArray *)views      superviewWidth:(float)width              origin:(CGPoint)origin            distance:(float)distance{    for (int i = 0; i < views.count; i++) {        UIView *view = views[i];        //一共多少列        int column = (width - origin.x*2)/(view.width + distance);        //起始x+当前列数*(间隔+view.width) 当前列:i%列数        view.x = origin.x + i%column * (distance+view.width);        //起始y+当前行数*(间隔+view.height) 当前行:i/列数        view.y = origin.y + i/column * (distance+view.height);    }}

为了方便偷懒把创建button的代码也放上:

- (void)createBtns {    NSArray *titleArr = @[@"快捷回复", @"结束对话", @"下达医嘱", @"收起", @"坐诊信息", @"添加图片"];    NSArray *imgArr = @[@"qd_kjhf_n", @"qd_jsdh", @"qd_xdyz", @"qd_zk_n", @"qd_zzxx_n", @"qd_tjtp"];    NSMutableArray *btnArr = [NSMutableArray array];    for (int i = 0; i < titleArr.count; i++) {        UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];        btn.size = CGSizeMake(44, 46);        [btn setTitle:titleArr[i] forState:UIControlStateNormal];        [btn setImage:[UIImage imageNamed:imgArr[i]] forState:UIControlStateNormal];        [btn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];        //MARK: 上下排列图文        btn.titleLabel.font = [UIFont systemFontOfSize:10];        btn.titleEdgeInsets = UIEdgeInsetsMake(btn.imageView.height, -btn.imageView.width, 0, 0);        btn.imageEdgeInsets = UIEdgeInsetsMake(0, 0, btn.height - btn.imageView.height, -btn.titleLabel.width);        [_btnsContainer addSubview:btn];                btn.tag = i+200;        [btn addTarget:self action:@selector(btnAction:) forControlEvents:UIControlEventTouchUpInside];                [btnArr addObject:btn];    }    [self arrangeViews:btnArr superviewWidth:kScreenWidth column:4 origin:CGPointMake(22, 8) verticalDistance:6];}

哦对了,用了Category所以是view.x view.width这种写法
