我需要创建并填充自定义单元格。这些细胞高度约为300-400。
所以我有一个populateCellView函数，我在heightForRowAtIndexPath上调用该函数来计算高度，并在cellForRowAtIndexPath中将该视图添加到单元格内容视图中，但有时单元格重叠。< / p>
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
return [self populateCellView:indexPath.row].frame.size.height;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UIView *populateCell= nil;
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
populateCell=[[UIView alloc] initWithFrame:CGRectZero];
[[populateCell layer] setBorderWidth:2.0f];
populateCell= [self populateCellView:indexPath.row];
[[cell contentView] addSubview:populateCell];
}
if (!populateCell){
populateCell = (UIView*)[cell viewWithTag:1];
populateCell= [self populateCellView:indexPath.row];
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
return cell;
}
填充视图功能：
-(UIView *)populateCellView:(int)forCase
{
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0,0, self.view.frame.size.width,500)];
[view setBackgroundColor:[UIColor colorWithRed:40/255.0 green:150/255.0 blue:213/255.0 alpha:1.0]];
view.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
if ([view subviews]){
for (UIView *subview in [view subviews]) {
[subview removeFromSuperview];
}
}

CGFloat blueLevel = rand() / (float) RAND_MAX;
view.backgroundColor = [UIColor colorWithRed: redLevel
green: greenLevel
blue: blueLevel
alpha: 1.0];
return view;
}
我像这样调用重载数据
dispatch_async(dispatch_get_main_queue(), ^{
[_agenda loadFromPlist];
[[self tableView] reloadData];
});
知道细胞重叠的原因吗？

在UITableViewDataSource方法tableView:cellForRowAtIndexPath:的末尾，您必须调用[[cell contentView] addSubView:populateCell]。如果表成功地使单元格出列，则必须检索相应的populateCell并将其添加到contentView。

它的UITableview cellforIndexPath导致重叠
试试这个
if (!populateCell){
populateCell = (UIView*)[cell viewWithTag:1];
populateCell= [self populateCellView:indexPath.row];
if ([[cell contentView] subviews]){
for (UIView *subview in [[cell contentView] subviews]) {
[subview removeFromSuperview];
}
}
[[cell contentView] addSubview:populateCell];
}
cell.backgroundColor=[UIColor clearColor];

如果您使用故事板，并为单元格和表格视图中的行设置不同的高度，则高度通常会重叠。其他答案也非常有效，但通常当我遇到这个问题时，错误在于故事板中tableview对象中行高和单元格高度的不同值...
