有时我们需要动态调整UITableViewCell的高度,根据内容的不同设置不同的高度,以前看到一种实现方法,写得有点麻烦,具体地址找不到了,这里有个更好的(至少我认为),分享一下部分代码。
- - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
- static NSString *CellIdentifier = @"Cell";
- UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
- if (cell == nil) {
- cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
- UILabel *label = [[UILabel alloc] initWithFrame:CGRectZero];
- label.tag = 1;
- label.lineBreakMode = UILineBreakModeWordWrap;
- label.highlightedTextColor = [UIColor whiteColor];
- label.numberOfLines = 0;
- label.opaque = NO; // 选中Opaque表示视图后面的任何内容都不应该绘制
- label.backgroundColor = [UIColor clearColor];
- [cell.contentView addSubview:label];
- [label release];
- }
- UILabel *label = (UILabel *)[cell viewWithTag:1];
- NSString *text;
- text = [textArray objectAtIndex:indexPath.row];
- CGRect cellFrame = [cell frame];
- cellFrame.origin = CGPointMake(0, 0);
- label.text = text;
- CGRect rect = CGRectInset(cellFrame, 2, 2);
- label.frame = rect;
- [label sizeToFit];
- if (label.frame.size.height > 46) {
- cellFrame.size.height = 50 + label.frame.size.height - 46;
- }
- else {
- cellFrame.size.height = 50;
- }
- [cell setFrame:cellFrame];
- return cell;
- }
- - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
- {
- UITableViewCell *cell = [self tableView:tableView cellForRowAtIndexPath:indexPath];
- //UITableViewCell *cell = [self cellForRowAtIndexPath:indexPath];
- return cell.frame.size.height;
- }
