大家好，我有自定义tableview cells名为product cell,rating cell,notify cell，其中product cell包含textfield section 0,1,2,4中使用的textfileds。问题是如果我在section 0中的textfileds中输入文字。滚动时我在section1,2中的 -(ProductCell *)getProductCell
{
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"ProductCell" owner:nil options:nil];
ProductCell *cell;
for (id currentObject in topLevelObjects)
{
if ([currentObject isKindOfClass:[ProductCell class]])
{
cell= (ProductCell*)currentObject;
return cell;
}
}
return nil;
}
-(RatingCell *)getRatingCell
{
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"RatingCell" owner:nil options:nil];
RatingCell *cell;
for (id currentObject in topLevelObjects)
{
if ([currentObject isKindOfClass:[RatingCell class]])
{
cell= (RatingCell*)currentObject;
return cell;
}
}
return nil;
}
-(NotifyCell *)getNotifyCell
{
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"NotifyCell" owner:nil options:nil];
NotifyCell *cell;
for (id currentObject in topLevelObjects)
{
if ([currentObject isKindOfClass:[NotifyCell class]])
{
cell= (NotifyCell *)currentObject;
return cell;
}
}
return nil;

上留下了文字印象。你们可以帮帮我。下面是代码

您的表格视图单元格正在重复使用。这是表格视图单元格优化的方式。
如果您确切知道表视图有多少个部分和行，并且它们不会更改，请考虑使用也适用于表单的静态表视图单元格：
查看静态行内容技术部分。
否则，您需要将每个文本字段的值保存到变量中，例如评级，电子邮件，描述，并在每次加载相应的表格视图单元格时将其重新放回文本字段。
