1.通过xib创建一个cell,将label进行上左下右,进行适配,
self.automaticallyAdjustsScrollViewInsets = NO;
self.edgesForExtendedLayout = UIRectEdgeNone;//将原点移动到navigationBar下面去了
tableView.estimatedRowHeight = 37.0;//估计cell的高度
tableView.rowHeight = UITableViewAutomaticDimension;//行高自适应
//选中cell的时候让cell自适应高度
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:true];
WLTableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
UILabel *label = [cell.contentView viewWithTag:1000];
[tableView beginUpdates];//开始更新
if (label.numberOfLines == 0) {
label.numberOfLines = 1;
}else{
label.numberOfLines = 0;
}
[tableView endUpdates];//结束更新
}
//cell显示的时候做一个动画
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
CGFloat offSet = tableView.contentOffset.y;
if (offSet <=0) {
return;
}
CGRect oldRect = cell.frame;
CGRect newRect = cell.frame;
newRect.origin.y += 50;
cell.frame = newRect;
[UIView animateWithDuration:0.5 animations:^{
cell.frame = oldRect;
}];
}
