设置cell高度
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
NoticeMessage* msg = [arrayNoticeMessage objectAtIndex:indexPath.section];//取出对应的section或者cell
UIFont *msgFont = [UIFont fontWithName:@"arial" size:15];//设置字体与字号
//定义行高
uint textLineheight = [@"The brown fox jumps over the lazy dog" sizeWithFont:msgFont constrainedToSize:CGSizeMake(MAXFLOAT, MAXFLOAT)].height;
//设置内容高度
CGSize infoSize = [msg.strContent sizeWithFont:msgFont constrainedToSize:CGSizeMake(170, MAXFLOAT) lineBreakMode:UILineBreakModeWordWrap];
return infoSize.height;
设置label高度，在下面方法中
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *DetailCellIdentifier = @"ValueDetailCell";
static NSString *SimpleCellIdentifier = @"ValueDetailSimpleCell";
NSLog(@"section %d",indexPath.section);
//带图的信息
NoticeMessage* msg = [arrayNoticeMessage objectAtIndex:indexPath.section];
DetailInfoTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:DetailCellIdentifier];
if (cell == nil) {
cell = [[DetailInfoTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:DetailCellIdentifier];
}
cell.contentView.layer.cornerRadius = 3;
cell.contentView.layer.masksToBounds = YES;
cell.contentView.layer.bounds = CGRectMake(0, 0, cell.contentView.frame.size.width, cell.contentView.frame.size.height-50);
cell.contentView.backgroundColor = [UIColor colorWithWhite:0.8 alpha:0.3];
cell.InfoDate.text = msg.strDate;
cell.InfoTitle.text = msg.strTitle;
cell.InfoContent.text = msg.strContent;
//cell.InfoDate.text = msg.strTimeStamp;
cell.backgroundColor = [UIColor clearColor];
//设置label的高度；
UIFont *msgFont = [UIFont fontWithName:@"arial" size:15];
CGSize infoSize = [msg.strContent sizeWithFont:msgFont constrainedToSize:CGSizeMake(170, MAXFLOAT) lineBreakMode:UILineBreakModeWordWrap];
CGRect frame = cell.InfoContent.frame;
frame.size.height = infoSize.height;
[cell.InfoContent setFrame:frame];
return cell;
}
