答：搜索URLDecode解码。
2.在使用代理方法tableView viewForHeaderInSection 时会出现一个问题
最初代码：
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
static NSString *identifier = @"headViewIdentifer";
UITableViewCell *headView = [tableView dequeueReusableCellWithIdentifier:identifier];
return headView;
}
如果你加入TextFiled此类输入型控件的时候，就会出现no index path for table cell being reused 然后 head view就消失不见
同时，收回键盘Dismiss on drag也出现的问题是
[UIWindow endDisablingInterfaceAutorotationAnimated:] called on> without matching -beginDisablingInterfaceAutorotation. Ignoring.
答：解决办法加入view，此外autoresizingMask自己试试哪个合适你自己的
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
static NSString *identifier = @"headViewIdentifer";
UITableViewCell *headView = [tableView dequeueReusableCellWithIdentifier:identifier];
UIView *view = [[UIView alloc]initWithFrame:[headView frame]];
headView.autoresizingMask = UIViewAutoresizingFlexibleWidth;
[view addSubview:headView];
return view;
}
收回键盘使用endEditing
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
[scrollView endEditing:YES];
}
3.在Tableview的head view和cell之间有一个横线，白色的

答：解决办法就是填充cell和head view的background颜色，两个都要填

4.如何tableview 的Cell滚动顶部键盘挡不住
答：
NSIndexPath *scrollIndexPath = [NSIndexPath indexPathForRow:indexPath.row inSection:indexPath.section];
[self.tableView scrollToRowAtIndexPath:scrollIndexPath
atScrollPosition:UITableViewScrollPositionTop animated:YES];
5.如何跳到AppStore的评论页?
