在cell.m文件中
1）初始化方法中：
self.lalName=[[UILabel alloc] initWithFrame:CGRectMake(71, 5, 250, 40)];
[self addSubview:self.lalName];
2）创建方法：
//给用户介绍赋值并且实现自动换行
-(void)setIntroductionText:(NSString*)text{
//获得当前cell的高度
CGRect frame=[self frame];
//文本赋值
self.lalName.text=text;
CGSize size=CGSizeMake(300, 1000);
//设置label的最大行数
self.lalName.numberOfLines=10;
CGSize labelSize=[self.lalName.text sizeWithFont:self.lalName.font constrainedToSize:size lineBreakMode:NSLineBreakByClipping];
self.lalName.frame=CGRectMake(self.lalName.frame.origin.x, self.lalName.frame.origin.y, labelSize.width, labelSize.height) ;
//计算出自适应的高度
frame.size.height=labelSize.height+20;
self.frame =frame;
}
在ViewController中：
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *acell=@"acell";
TextKitTableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:acell];
if (!cell) {
cell=[[[NSBundle mainBundle] loadNibNamed:@"TextKitTableViewCell" owner:self options:nil]lastObject];
}
[cell setIntroductionText:@"where are you? where are you? where are you? where are you? where are you? where are you? where are you? where are you? where are you? where are you?where are you? where are you? where are you? where are you? where are you? where are you? where are you? where are you? where are you? where are you?"];
return cell;
}
当然别忘记了返回给cell高度
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell=[self tableView:self.tableViewTextKit cellForRowAtIndexPath:indexPath];
NSLog(@"height===%f",cell.frame.size.height);
return cell.frame.size.height;
}
