iphone 开发笔记五

41、将字符串分割成数组
temparray = [tempstring componentsSeparatedByString:@"<wbr style="margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px; padding-top:0px; padding-right:0px; padding-bottom:0px; padding-left:0px; text-decoration:none">,"];<br style="margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px; padding-top:0px; padding-right:0px; padding-bottom:0px; padding-left:0px; text-decoration:none"></wbr>

<wbr style="margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px; padding-top:0px; padding-right:0px; padding-bottom:0px; padding-left:0px; text-decoration:none"></wbr>

<wbr style="margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px; padding-top:0px; padding-right:0px; padding-bottom:0px; padding-left:0px; text-decoration:none"></wbr>

42、可编辑表格
[self.tableView setEditing:TRUE];

43、表格划动行显示删除按钮
- (void)tableView:(UITableView *)tv commitEditingStyle:(<wbr style="margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px; padding-top:0px; padding-right:0px; padding-bottom:0px; padding-left:0px; text-decoration:none">UITableViewCellEditingStyle)<wbr style="margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px; padding-top:0px; padding-right:0px; padding-bottom:0px; padding-left:0px; text-decoration:none">editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {<br style="margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px; padding-top:0px; padding-right:0px; padding-bottom:0px; padding-left:0px; text-decoration:none"> }<br style="margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px; padding-top:0px; padding-right:0px; padding-bottom:0px; padding-left:0px; text-decoration:none"></wbr></wbr>
