ios - viewForFooterInSection 未显示在屏幕底部

Question

viewForFooterInSection 未显示在屏幕底部 (uitableview)。这里我使用的是 UItableview。

注意:在下面的屏幕变化中，屏幕底部又添加了一个页脚。(白色 View )。Redcolorview:页脚(来自下面的代码)蓝色:表格背景色白底:

我使用以下代码以编程方式添加的红色 View :

- (CGFloat)tableView:(UITableView *)tableView 
estimatedHeightForFooterInSection:(NSInteger)section
{
    return 44;
}
- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{
    NSLog(@"%f",tableView.frame.size.width);

    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 44)];
    view.backgroundColor = [UIColor redColor];
    UIButton *cancelButton = [[UIButton alloc]initWithFrame:CGRectMake(30, 7, tableView.frame.size.width/2 - 60, 30)];
    [cancelButton setTitle:@"Cancel" forState:UIControlStateNormal];
    [cancelButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
    [cancelButton setBackgroundColor:[ValidationsClass colorWithHexString:NSLocalizedStringFromTableInBundle(@"pothysapp_label_text_backgroundcolor",@"ApplicationSettings",[NSBundle mainBundle], nil)]];
    [cancelButton addTarget:self
                     action:@selector(cancelDetails:)
           forControlEvents:UIControlEventTouchUpInside];
    cancelButton.titleLabel.font = [UIFont fontWithName:@"Roboto-Bold" size:15];
    cancelButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
    [view addSubview:cancelButton];

    UIButton *saveButton = [[UIButton alloc]initWithFrame:CGRectMake(tableView.frame.size.width/2 + 30, 7, tableView.frame.size.width/2 - 60, 30)];
    [saveButton setTitle:@"Save" forState:UIControlStateNormal];
    [saveButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
    [saveButton setBackgroundColor:[ValidationsClass colorWithHexString:NSLocalizedStringFromTableInBundle(@"pothysapp_label_text_backgroundcolor",@"ApplicationSettings",[NSBundle mainBundle], nil)]];
    [saveButton addTarget:self
                   action:@selector(saveDetails:)
         forControlEvents:UIControlEventTouchUpInside];
    saveButton.titleLabel.font = [UIFont fontWithName:@"Roboto-Bold" size:15];
    saveButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
    [view addSubview:saveButton];

    return view;
}

试试这个，而不是在 viewForFooterInSection 中返回您的自定义 View 。

在 ViewdidLoad() 中将您的自定义 View 添加到表页脚

self.tableview.tableFooterView =//Your CustomView;
