我有UItableview，其中每个包含5个单元格的单元格和这些单元格代表一些已解析的xml数据。当UITableview在视图控制器的开头执行时，它会在正确的单元格中显示正确的数据。一个NSMutableArray但现在我的问题是从xml文件滚动到新数据以获取更新数据然后数据变得分散，不同的单元表示不同的数据。如果我解释那么..
第一个单元格，所以索引编号为1，但在刷新表格单元格1后显示数据单元格5或任何其他单元格表示单元格实际上没有重叠但其数据表示错误的方式..我找不到解决方案请任何人帮助我......
这是我的tableview单元格代码

刷新表代码......
- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView {
if (isLoading) return;
isDragging = YES;
}
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
if (isLoading) {
// Update the content inset, good for section headers
if (scrollView.contentOffset.y > 0){
NSLog(@"scrollView.contentOffset.y 1= %d",scrollView.contentOffset.y );
tableview.contentInset = UIEdgeInsetsZero;
}
else if (scrollView.contentOffset.y >= -REFRESH_HEADER_HEIGHT){
NSLog(@"scrollView.contentOffset.y 2= %d",scrollView.contentOffset.y );
tableview.contentInset = UIEdgeInsetsMake(-scrollView.contentOffset.y, 0, 0, 0);
}
} else if (isDragging && scrollView.contentOffset.y < 0) {
// Update the arrow direction and label
[UIView beginAnimations:nil context:NULL];
if (scrollView.contentOffset.y < -REFRESH_HEADER_HEIGHT) {
// User is scrolling above the header
NSLog(@"scrollView.contentOffset.y 3= %d",scrollView.contentOffset.y );
refreshLabel.text = self.textRelease;
[refreshArrow layer].transform = CATransform3DMakeRotation(M_PI, 0, 0, 1);
} else { // User is scrolling somewhere within the header
refreshLabel.text = self.textPull;
[refreshArrow layer].transform = CATransform3DMakeRotation(M_PI * 2, 0, 0, 1);
}
[UIView commitAnimations];
}
}
- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate {
if (isLoading) return;
isDragging = NO;
if (scrollView.contentOffset.y <= -REFRESH_HEADER_HEIGHT) {
// Released above the header
[self startLoading];
}
}
return cell;
}
还有其他问题请告诉我..我很早就需要这个解决方案......
先谢谢
答案 0 :(得分：2)
尝试将“MyIdentifier”更改为“nil” UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier：nil];
希望这项工作！和平
