1、UITextView在UITableViewCell 中自适应高度的问题
1 -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 2 { 3 。。。。。。 4 5 UITextView * contentView = [[UITextView alloc] initWithFrame:CGRectZero]; 6 contentView.textColor = [UIColor colorWithRed:80.0/255.0 green:132.0/255.0 blue:183.0/255.0 alpha:1.0]; 7 [contentView setFont:[UIFont systemFontOfSize:12.0f]]; 8 [contentView setBackgroundColor:[UIColor clearColor]]; 9 [contentView setEditable:NO]; 10 contentView.contentInset = UIEdgeInsetsMake(15,-8,0,18);//这句很重要，因为textview中的text也是有自己的边界的。 11 [cellBgView addSubview:contentView]; 12 13 NSString *text = [contentArray objectAtIndex:[indexPath section]]; 14 CGSize constraint = CGSizeMake(200, 20000.0f); 15 CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:12.0f] constrainedToSize:constraint lineBreakMode:NSLineBreakByWordWrapping]; 16 [contentView setFrame:CGRectMake(10, 10, 280, MAX(size.height, 44.0f))]; 17 18 }
1 - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath 2 { 3 NSString *text = [contentArray objectAtIndex:[indexPath section]]; 4 CGSize constraint = CGSizeMake(200, 20000.0f); 5 CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:12] constrainedToSize:constraint lineBreakMode:NSLineBreakByWordWrapping]; 6 CGFloat height = MAX(size.height, 44.0f); 7 return height + (10 * 2); 8 }
