在 tableview 下添加按钮 [英] Add buttons under a tableview

问题描述

我正在尝试以编程方式创建视图.我想要的结果是一个带有 tableview 的滚动视图.在这个表格视图下我想添加一些按钮

I'm trying to create a view programmatically. The result that i want to have is a scroll view with a tableview inside. And under this table view i want to add some buttons

我不知道该怎么做，我试过了，但它不起作用:

I don't know exactly how to do that i tried this but it doesn't work :

- (void)loadView {
    [super loadView];

    tableView = [[UITableView alloc] initWithFrame:[[self view] bounds] style:UITableViewStyleGrouped];
    [tableView setDelegate:self];
    [tableView setDataSource:self];

    scrollView = [[UIScrollView alloc] initWithFrame:[[self view] bounds]];
    //[scrollView setBackgroundColor:[UIColor blackColor]];
    [scrollView setBouncesZoom:YES];

    deconnectButton = [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain];
    [deconnectButton setTitle:@"Deconect" forState:UIControlStateNormal];
    [deconnectButton setTitleColor:[UIColor orangeColor] forState:UIControlStateNormal];

    //[deconnectButton addTarget:self action:action forControlEvents:UIControlEventTouchUpInside]; 
    deconnectButton.frame = tableView.frame;
    NSLog(@"Tableview frame : %@", NSStringFromCGRect(tableView.frame));

    [scrollView addSubview:deconnectButton];

    [scrollView addSubview:tableView];


    [[self view] addSubview:scrollView];


}

我错过了什么或做错了什么?

What am i missing or doing wrong?

推荐答案

其实我找到了解决方案.tableview 有一个名为 tableFooterView 的属性.你所要做的就是:

Actually i found the solution. the tableview has a property named tableFooterView. All you have to do is to :

-创建一个 UIView- 在此视图中添加一个按钮- 最后将其设置在 tableFooterView 上

-Create a UIView -Add a button to this view -Finaly set it on the tableFooterView

代码如下:

tableView = [[UITableView alloc] initWithFrame:[[self view] bounds] style:UITableViewStyleGrouped];
[tableView setDelegate:self];
[tableView setDataSource:self];

// create a UIButton (Deconnect button)
UIButton *btnDeco = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btnDeco.frame = CGRectMake(0, 0, 280, 40);
[btnDeco setTitle:@"Déconnecter" forState:UIControlStateNormal];
btnDeco.backgroundColor = [UIColor clearColor];
[btnDeco setTitleColor:[UIColor orangeColor] forState:UIControlStateNormal];
[btnDeco addTarget:self action:@selector(deconnect:) forControlEvents:UIControlEventTouchUpInside];

// create a UIButton (Change pseudo button)
UIButton *btnChange = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btnChange.frame = CGRectMake(0, 50, 280, 40);
[btnChange setTitle:@"Changer Pseudo" forState:UIControlStateNormal];
btnChange.backgroundColor = [UIColor clearColor];
[btnChange setTitleColor:[UIColor orangeColor] forState:UIControlStateNormal];
[btnChange addTarget:self action:@selector(changePseudo:) forControlEvents:UIControlEventTouchUpInside];


//create a footer view on the bottom of the tabeview
UIView *footerView = [[UIView alloc] initWithFrame:CGRectMake(20, 0, 280, 100)];
[footerView addSubview:btnDeco];
[footerView addSubview:btnChange];

tableView.tableFooterView = footerView; 
[footerView release];

[[self view] addSubview:tableView];
