基本设置
self.myTableView.bounces = NO; // 取消弹簧效果
不要分割线：
self.myTableView.separatorStyle = UITableViewCellSeparatorStyleNone;
选中不显示：
cell.selectionStyle = UITableViewCellSelectionStyleNone;
//不显示垂直滚动条
self.myTableView.showsVerticalScrollIndicator = NO;
//右侧小箭头
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
//默认选中TableView第一行，没有动画及滚动效果，动画即滚动效果通过animated,position来设定
[self.tableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] animated:NO scrollPosition:UITableViewScrollPositionNone];
//获取当前选中的cell
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
获取想要的cell
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] ];
分组
分组的类型选plain才不会有headView显示的错误,尽量不用headview不同机型容易出问题
头部设置
//返回每组头部view
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{
NSString *str = [NSString stringWithString:_Mset[section]] ;
NSArray *arr = [str componentsSeparatedByString:@"-"];
str = [NSString stringWithFormat:@" %@月%@日",arr[1],arr[2]];
UIView *headerView = [[UIView alloc]init];
headerView.backgroundColor = [UIColor groupTableViewBackgroundColor];
UILabel *label = [[UILabel alloc]init];
label.textColor = [UIColor grayColor];
label.font = [UIFont systemFontOfSize:13];
label.textColor = color_light_gray;
label.frame = CGRectMake(10, 6, 100, 20);
label.text = str;
[headerView addSubview:label];
return headerView;
}
分组取一
self.currentExpress = [self.dictExpress objectForKey:self.firstPinyinArr[indexPath.section]];
self.currentModel = self.currentExpress[indexPath.row];
选中指定行并跳转
[self tableView:self.FirstCategoryTable didSelectRowAtIndexPath:[NSIndexPath indexPathForRow:self.selectIndex inSection:0]];
[self.FirstCategoryTable selectRowAtIndexPath:[NSIndexPath indexPathForRow:self.selectIndex inSection:0] animated:YES scrollPosition:UITableViewScrollPositionMiddle];
iOS监听tableView组头切换事件
- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section 组头将要出现的时候系统会调用；
- (void)tableView:(UITableView *)tableView didEndDisplayingHeaderView:(UIView *)view forSection:(NSInteger)section 组头出现的时候系统会调用；
利用以上两个方法可以判断出组头被顶出和组头又下拉回来事件，还有其他的组头相关动作可以监听需自己去编写。
cell背景透明
1，设置控制器的背景色
2，设置tableview透明
3，设置cell透明
4，设置cell 的view不透明
拿到Cell的值
cell的.h方法获取cell的一些控件值
带圆角的多个cell（只有前后有圆角）
self.currentExpress = [self.dictExpress objectForKey:self.firstPinyinArr[indexPath.section]];
self.currentModel = self.currentExpress[indexPath.row];
self.currentExpressName = self.currentModel.name;
self.currentExpressCode = self.currentModel.code;
if (0 == indexPath.row) {
[cell setName:self.currentExpressName andType:KCell_First];
}else if (self.currentExpress.count -1 == indexPath.row){
[cell setName:self.currentExpressName andType:KCell_Last];
}else{
[cell setName:self.currentExpressName andType:KCell_Other];
}
Cell
-(void)setName:(NSString *)name andType:(NSString *)type{
if ([@"isFirst" isEqualToString:type]) {
UIBezierPath* rounded = [UIBezierPath bezierPathWithRoundedRect:CGRectMake(0, 0, screenWidth-24,40) byRoundingCorners:UIRectCornerTopLeft | UIRectCornerTopRight cornerRadii:CGSizeMake(5, 5)];
CAShapeLayer* shape = [[CAShapeLayer alloc] init];
[shape setPath:rounded.CGPath];
self.baseView.layer.mask = shape;
}else if([@"isLast" isEqualToString:type]){
UIBezierPath* rounded = [UIBezierPath bezierPathWithRoundedRect:CGRectMake(0, 0, screenWidth-24,40) byRoundingCorners:UIRectCornerBottomLeft | UIRectCornerBottomRight cornerRadii:CGSizeMake(5, 5)];
CAShapeLayer* shape = [[CAShapeLayer alloc] init];
[shape setPath:rounded.CGPath];
self.baseView.layer.mask = shape;
}
self.expressName.text = name;
}
tableView头容器
头尾容器会和tableview一起动，而分组头不会动
sendDetailsHeadView * headView = [[NSBundle mainBundle]loadNibNamed:@"sendDetailsHeadView" owner:nil options:nil].lastObject;
headView.bounds = CGRectMake(0, 0, screenWidth-30, 270);
[headView setWithHeadModel:self.headModel];
self.sendDetailsTable.tableHeaderView = headView;
代理方法
1,设置代理 <UITableViewDelegate,,UITableViewDataSource>
2,实现方法
分组个数： numberOfSectionsInTableView
每组个数 ：numberOfRowsInSection
加载 cell：cellForRowAtIndexPath
1,设置 cell 的复用 id（在 cell 中设置）
2，注册 id [self.detailTable registerNib:[UINib nibWithNibName:DailyPriceTimeCellID bundle:nil] forCellReuseIdentifier:DailyPriceTimeCellID];
(这里 nib 的 name 作为 Identifier，nibname 不能错)
3，复用DailyPriceTimeCell *cell = [tableView dequeueReusableCellWithIdentifier:DailyPriceTimeCellID];
[cell setUPModel:self.priceModel];
return cell;
设置分组头 ：viewForHeaderInSection
分组头的高度：heightForHeaderInSection
设置每行的高度：heightForRowAtIndexPath
非等高 cell 要先设置估计高度：estimatedHeightForRowAtIndexPath
Cell按钮跳转
点击 cell 中的按钮实现界面的跳转，要在 cell 写代理，点击按钮调用代理，在 cell 的控制器中调用实现的代理方法。
-(void)goMyBuy
{
myBuyAndSellPage * myBuy = [[myBuyAndSellPage alloc] initWithAction:kBuyOrSell_Buy];
myBuy.hidesBottomBarWhenPushed = YES;
[self.navigationController pushViewController:myBuy animated:YES];
}
长按cell删除
// 手势
UILongPressGestureRecognizer *labelLongPressGestureRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self
action:@selector(deleteCardClick:)];
// 2. 将点击事件添加到label上
labelLongPressGestureRecognizer.minimumPressDuration=1.5f;
[cell addGestureRecognizer:labelLongPressGestureRecognizer];
-(void)deleteCardClick:(UILongPressGestureRecognizer *)longRecognizer{
if (longRecognizer.state == UIGestureRecognizerStateBegan) {//手势开始
[self becomeFirstResponder];
CGPoint location = [longRecognizer locationInView:self.cardBagTable];
NSIndexPath * indexPath = [self.cardBagTable indexPathForRowAtPoint:location];
//可以得到此时你点击的哪一行
self.selectThirdModel = self.cardBag[indexPath.row];
}
UIAlertController* alert = [UIAlertController alertControllerWithTitle:@"提示"
message:@"删除卡包"
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:@"删除" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
//响应事件
[self canDeleteCard];
}];
UIAlertAction* cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
//响应事件
}];
[alert addAction:defaultAction];
[alert addAction:cancelAction];
[self presentViewController:alert animated:YES completion:nil];
}
当超过tableView显示的范围的时候 后面显示的内容将会和前面重复
self.selectCellRow 记录当前选中的cell，只有刷新到选中cell的时候，才改到选中的状态
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
FirstCategoryCell *cell = [tableView dequeueReusableCellWithIdentifier:FirstCategoryCellID];
cell.leftLine.hidden = YES;
cell.selectionStyle = UITableViewCellSelectionStyleNone;
if (indexPath.row == self.selectCellRow) {
cell.leftLine.hidden = NO;
}
[cell setUpModel:self.fModels[indexPath.row]];
return cell;
}
下拉放大脑壳
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
//往上滑动offset增加，往下滑动，yoffset减小
CGFloat yoffset = scrollView.contentOffset.y;
if (yoffset<headerHeight) {//滑动到导航栏地底部之前
}else {//超过导航栏底部
}
//处理放大效果和往上移动的效果
if (yoffset>0) {//往上滑动
self.headerView.frame = ({
CGRect frame = originFrame;
frame.origin.y = originFrame.origin.y - yoffset;
frame;
});
}else {//往下滑动，放大处理
self.headerView.frame = ({
CGRect frame = originFrame;
frame.size.height = originFrame.size.height - yoffset;
frame.size.width = frame.size.height/scale;
frame.origin.x = originFrame.origin.x - (frame.size.width-originFrame.size.width)/2;
frame;
});
}
}
滚动到指定位置
滚动到指定位置
[self.SecondCategoryTable scrollToRow:0 inSection:0 atScrollPosition:UITableViewScrollPositionTop animated:YES];
滚动到指定位置并选中
[self.adressTable selectRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] animated:NO scrollPosition:UITableViewScrollPositionTop];
