    <p>Hi all I am developing an app.I want to show a table view with a header view.When i navigate from Root view to Next view(tableview) which is as shown below.But my question is when i passes some text from root view to Next view(table view) as a header to next view it shows like the following in appropriate format.i need solution for this to show some better format.Following code that i used for this.<img src="https://i.stack.imgur.com/iknNj.png" alt="enter image description here"></p> <pre><code>- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section { /* NSString *str_header1; str_header1=[[NSString alloc]initWithString:@"Heading : "]; str_header1=[str_header1 stringByAppendingFormat:str_code1]; str_header1=[str_header1 stringByAppendingFormat:@" - "]; str_header1=[str_header1 stringByAppendingFormat:str_header]; */ // Create label with section title UILabel *tmpTitleLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 15, 300, 20)]; UILabel *titleLabel = tmpTitleLabel; titleLabel.font = [UIFont boldSystemFontOfSize:12]; titleLabel.numberOfLines = 0; titleLabel.textColor = [UIColor colorWithRed:0.30 green:0.34 blue:0.42 alpha:1.0]; titleLabel.shadowColor = [UIColor whiteColor]; titleLabel.shadowOffset = CGSizeMake(0.0, 1.0); titleLabel.backgroundColor=[UIColor clearColor]; titleLabel.lineBreakMode = UILineBreakModeWordWrap; titleLabel.text = str_combine; //Calculate the expected size based on the font and linebreak mode of label CGSize maximumLabelSize = CGSizeMake(300,9999); expectedLabelSize= [str_combine sizeWithFont:titleLabel.font constrainedToSize:maximumLabelSize lineBreakMode:titleLabel.lineBreakMode]; //Adjust the label the the new height CGRect newFrame = titleLabel.frame; newFrame.size.height = expectedLabelSize.height; titleLabel.frame = newFrame; // Create header view and add label as a subview UIView *view = [[UIView alloc] initWithFrame:CGRectMake(10, 0, 320, expectedLabelSize.height+30)]; [view addSubview:titleLabel]; return view; </code></pre> <p>}</p> <pre><code>- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection: (NSInteger)section { return expectedLabelSize.height+30; } </code></pre>

    2. COdo not use heightForHeaderInsectio method of delegate. If you are using xib then set default section height for tableView. Hope tis will help.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
