我想实现这样的目标

在此处输入图像描述

主要用于说明目的，是否有我不知道的 UITableView 方法，或者有某种技巧。

这是写在 UItableView 的 Header 和 Footer 中的。所以自定义表中section的headerView和footerView。

使用这些方法：

-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section

-(UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section

希望它可以帮助你。

您在我的应用程序中遵循它对我有用的方法：

- (void)viewDidLoad {
    [super viewDidLoad];

    /* ios 7 Change */
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7)
    {
        self.edgesForExtendedLayout = UIRectEdgeNone;
         self.edgesForExtendedLayout = UIRectEdgeNone;
         self.tableview.separatorInset = UIEdgeInsetsZero;
         [self.tableview setSeparatorStyle:UITableViewCellSeparatorStyleNone];
   }
}

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
    NSString *header;

    float start = 10.0, startLabel = 10.0;

    if ([UICommonUtils isiPad]) 
    {
        startLabel = 50.0;
    } else {
        startLabel = 10.0;
    }

    CGRect rectFrame = [UIScreen mainScreen].applicationFrame;


        UIView* customView = [[[UIView alloc] 
                           initWithFrame:CGRectMake(start, 0.0, rectFrame.size.width - 20.0, 80.0)]
                          autorelease];
    /*
     customView.backgroundColor = 
     [UIColor colorWithRed:.6 green:.6 blue:1 alpha:.9];
     */
        UILabel * headerLabel = [[[UILabel alloc] initWithFrame:CGRectZero] autorelease];

        headerLabel.textColor = [UIColor colorWithRed:0.298039 green:0.337255 blue:0.423529 alpha:1];

        headerLabel.shadowOffset = CGSizeMake(0.0, 1.0);
        headerLabel.font = [UIFont boldSystemFontOfSize:17.0];
        //headerLabel.frame = CGRectMake(startLabel, 0, rectFrame.size.width - 60.0, 20.0);

        headerLabel.text = header;
        headerLabel.baselineAdjustment = UIBaselineAdjustmentAlignCenters;

        UILabel * footerLabel = [[[UILabel alloc] initWithFrame:CGRectZero] autorelease];
        //UILabel *footerLabel = [[[UILabel alloc] initWithStyle:UITableViewCellStyleDefault] autorelease];
        footerLabel.backgroundColor = [UIColor clearColor];
        footerLabel.opaque = NO;
        //footerLabel.textColor = [UIColor darkGrayColor];

        footerLabel.shadowColor = [UIColor whiteColor];
        footerLabel.shadowOffset = CGSizeMake(0.0, 1.0);
        footerLabel.font = [UIFont systemFontOfSize:14.0];
        float height;

        footerLabel.lineBreakMode = UILineBreakModeWordWrap;
        footerLabel.baselineAdjustment = UIBaselineAdjustmentNone;
        footerLabel.numberOfLines = 0;
        footerLabel.text = detail;

        [customView addSubview:headerLabel];
        [customView addSubview:footerLabel];

        return customView;
}

如果您想制作相同类型的视图（如上图所示），请在该部分的页脚中放置一个标签，使标签的背景透明并根据您的选择设置其框架并添加您想要的文本放在那里。让我给你一个可能对你有帮助的代码片段。

UILabel *tableFooter = [[UILabel alloc] initWithFrame:footerRect];
tableFooter.textColor = // add color of your choice
tableFooter.backgroundColor = // add color of your choice
tableFooter.opaque = YES;
tableFooter.font = [UIFont boldSystemFontOfSize:15];
tableFooter.text = @" add text of your choice";
self.theTable.tableFooterView = tableFooter;
[tableFooter release];

将上面的代码放在这个方法中：

- (UIView *) tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
