Question

我想实现类似的目标

enter image description here

主要用于指令目的，是否有我不知道的UITableView方法，或者有某种技巧。

Answer 1

这是在UItableView的页眉和页脚中编写的。因此，请自定义表格中各节的headerView和footerView。

使用以下方法：

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

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

希望它对你有所帮助。

Answer 2

查看此委托方法：

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

Answer 3

如果你想制作同样的视图（如上图所示），在标题的页脚中放一个标签，使标签的背景透明，并根据你的选择设置框架，并添加文字你想放在那里。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];

将以上代码放在此方法中：

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

Answer 4

您可以在我的应用中使用以下方法：

- (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];
        //UILabel * headerLabel = [[[UILabel alloc] initWithStyle:UITableViewCellStyleDefault] autorelease];
        headerLabel.backgroundColor = [UIColor clearColor];
        headerLabel.opaque = NO;
        //headerLabel.textColor = [UIColor darkGrayColor];
        headerLabel.textColor = [UIColor colorWithRed:0.298039 green:0.337255 blue:0.423529 alpha:1];
        headerLabel.shadowColor = [UIColor whiteColor];
        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.frame = CGRectMake(startLabel, 10, rectFrame.size.width - 35.0, 20.0);
        headerLabel.textAlignment = UITextAlignmentLeft;
        headerLabel.lineBreakMode = UILineBreakModeWordWrap;
        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.textColor = [UIColor colorWithRed:0.298039 green:0.337255 blue:0.423529 alpha:1];
        footerLabel.shadowColor = [UIColor whiteColor];
        footerLabel.shadowOffset = CGSizeMake(0.0, 1.0);
        footerLabel.font = [UIFont systemFontOfSize:14.0];
        float height;
        if ([UICommonUtils isiPad])
            height = 40.0;
        else 
            height = 50.0;
        footerLabel.frame = CGRectMake(startLabel, 20, rectFrame.size.width - 60.0, height);
        footerLabel.textAlignment = UITextAlignmentLeft;
        footerLabel.lineBreakMode = UILineBreakModeWordWrap;
        footerLabel.baselineAdjustment = UIBaselineAdjustmentNone;
        footerLabel.numberOfLines = 0;
        footerLabel.text = detail;

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

        return customView;
}
