大家好，我正在开发一个应用程序。我想显示一个带有标题视图的表格视图。当我从根视图导航到下一个视图（表格视图）时，如下所示。但我的问题是当我从根视图传递一些文本时到下一个视图（表格视图）作为下一个视图的标题，它以适当的格式显示如下。我需要解决方案来显示一些更好的格式。以下我用于此的代码。
- (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;
}
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection: (NSInteger)section
{
return expectedLabelSize.height+30;
}
