cell 分割线左对齐
-(void)viewDidLayoutSubviews {
if ([self.mytableview respondsToSelector:@selector(setSeparatorInset:)]) {
[self.mytableview setSeparatorInset:UIEdgeInsetsZero];
}
if ([self.mytableview respondsToSelector:@selector(setLayoutMargins:)]) {
[self.mytableview setLayoutMargins:UIEdgeInsetsZero];
}
}
-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPat{
if ([cell respondsToSelector:@selector(setLayoutMargins:)]) {
[cell setLayoutMargins:UIEdgeInsetsZero];
}
if ([cell respondsToSelector:@selector(setSeparatorInset:)]){
[cell setSeparatorInset:UIEdgeInsetsZero];
}
}
获取cell
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
刷新某一行row数据
NSIndexPath *indexPath=[NSIndexPath indexPathForRow:3 inSection:0];
[tableView reloadRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath,nil] withRowAnimation:UITableViewRowAnimationNone];
刷新某一组section数据
NSIndexPath *indexPath=[NSIndexPath indexPathForRow:3 inSection:0];
[tableView reloadRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath,nil] withRowAnimation:UITableViewRowAnimationNone];
设置自定义cell高度
//1.强制布局，让计算机算出当前cell的高度
[self layoutIfNeeded]; // 强制布局
//2.根据有无图片的情况，获取cell高度
if (status.picture) {
status.cellHeight = CGRectGetMaxY(self.pictureView.frame) + 10;
}else {
status.cellHeight = CGRectGetMaxY(self.contentLabel.frame) + 10;
}
