長いテキストを含むリスト ビューがあります。テキストが数段落の場合、途中で途切れてしまう傾向があります。奇妙な動作の一部は、常に同じ文字で切断されるわけではなく、一種のランダムであることです.
リストを作成するために使用するコードは次のとおりです。
// CREATING EACH CELL IN THE LIST
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
//static const NSInteger kLabelTag = 1;
UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:(UITableViewCellStyleDefault)
reuseIdentifier:@"business"];
NSString *comment = [[items_array objectAtIndex:[indexPath row]] objectForKey:(@"comment")];
NSString *first_name = [[items_array objectAtIndex:[indexPath row]] objectForKey:(@"first_name")];
//Boolean *is_private = [[items_array objectAtIndex:[indexPath row]] objectForKey:(@"is_private")];
// Creating a constraint size for the label you are making
CGSize constraint = CGSizeMake(320 - (10 * 2), 20000.0f);
// Determining the size that you will need for the label based on the comment
// length and the contraint size
CGSize size = [comment sizeWithFont:[UIFont systemFontOfSize:14] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
// Creating the label and initializing it with the frame that you have
// determined by your size calculations above
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, MAX(size.height, 44.0f) + 20.0f)];
// setting up the label properties
label.numberOfLines = 0;
label.lineBreakMode = UILineBreakModeWordWrap;
standardUserDefaults = [NSUserDefaults standardUserDefaults];
NSString *is_private = [standardUserDefaults objectForKey:@"is_private"];
if ( is_private == nil )
{
label.text = [first_name stringByAppendingString:[@": " stringByAppendingString:comment]]; // comment;
}
else
if ( [is_private isEqualToString:@"0"])
{
label.text = [first_name stringByAppendingString:[@": " stringByAppendingString:comment]]; // comment;
}
else
{
label.text = comment;
}
// adding the label view to the cell that you have created
[cell.contentView addSubview:label];
// CLOSE THE SPINNER
[spinner stopAnimating];
// return the cell for the table view
return cell;
}
//This method will determine how tall each row needs to be. Cell size for word wrapping.
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath;
{
NSString *comment = [[items_array objectAtIndex:[indexPath row]] objectForKey:(@"comment")];
// Again you are getting the constraints because you are going to us this size
// to constrain the height of the cell just like you determined the size for the label.
CGSize constraint = CGSizeMake(320 - (10 * 2), 20000.0f);
// Again, determining the size that we will need for the label, because it will drive
// the height of the cell
CGSize size = [comment sizeWithFont:[UIFont systemFontOfSize:14] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
// Finally, we can determine the height for the cell!
CGFloat height = MAX(size.height, 44.0f);
// return the height, which is the height of the label plus some extra space to make
// it look good.
return height + (10 * 2);
}
このコードに特に間違っている点はありますか? それとも、問題は別の場所に根ざしている可能性がありますか?
