如今,在5台显示可调用的电文电池板的官方接口。 例例(从表格代表处):

- (BOOL)tableView:(UITableView *)tableView shouldShowMenuForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return YES;
}

- (BOOL)tableView:(UITableView *)tableView canPerformAction:(SEL)action forRowAtIndexPath:(NSIndexPath *)indexPath withSender:(id)sender
{
    return (action == @selector(copy:));
}

- (void)tableView:(UITableView *)tableView performAction:(SEL)action forRowAtIndexPath:(NSIndexPath *)indexPath withSender:(id)sender
{
    if (action == @selector(copy:)){
        UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
        [[UIPasteboard generalPasteboard] setString:cell.textLabel.text];
    }
}

我试图修改UIMenuController的共享控制器,以添加我自己的菜单,我得以添加并获取canPerformAction的电文,但返回的YES确实没有帮助;我没有能够把我的习惯菜单列入项目。 从我的实验来看,它只看制版、Cut和Paste。 [EDIT 自张贴以来,我学会如何增加习俗菜单。]

请注意,只有在采用所有三种代表方法的情况下,才进行这项工作。

此处为“快速星号”复印件。

func tableView(_ tableView: UITableView, shouldShowMenuForRowAt indexPath: IndexPath) -> Bool {
    return (tableView.cellForRow(at: indexPath)?.detailTextLabel?.text) != nil
}

func tableView(_ tableView: UITableView, canPerformAction action: Selector, forRowAt indexPath: IndexPath, withSender sender: Any?) -> Bool {
    return action == #selector(copy(_:))
}

func tableView(_ tableView: UITableView, performAction action: Selector, forRowAt indexPath: IndexPath, withSender sender: Any?) {
    if action == #selector(copy(_:)) {
        let cell = tableView.cellForRow(at: indexPath)
        let pasteboard = UIPasteboard.general
        pasteboard.string = cell?.detailTextLabel?.text
    }
}

页: 1 电池子组可照此办理。

@interface MenuTableViewCell : UITableViewCell {
}
- (IBAction)copy:(id)sender;
- (void)showMenu;

@end


@implementation MenuTableViewCell

- (BOOL)canBecomeFirstResponder {
    return YES;
}
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
    if (action == @selector(copy:)) {
        return YES;
    }
    return NO;
}
- (IBAction)copy:(id)sender {
}
- (void)showMenu {
    [[UIMenuController sharedMenuController] setMenuVisible:NO animated:YES];
    [self becomeFirstResponder];
    [[UIMenuController sharedMenuController] update];
    [[UIMenuController sharedMenuController] setTargetRect:CGRectZero inView:self];
    [[UIMenuController sharedMenuController] setMenuVisible:YES animated:YES];

}

@end

友好通话代表方法也一样。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    MenuTableViewCell *cell = (MenuTableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[MenuTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }

    // Configure the cell.
    return cell;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    MenuTableViewCell *cell = (MenuTableViewCell *)[tableView cellForRowAtIndexPath:indexPath];
    [cell showMenu];
}

 #pragma mark - COPY/PASTE Cell Text via Menu

- (BOOL)tableView:(UITableView *)tableView shouldShowMenuForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return YES;
}

- (BOOL)tableView:(UITableView *)tableView canPerformAction:(SEL)action forRowAtIndexPath:(NSIndexPath *)indexPath withSender:(id)sender
{
    return (action == @selector(copy:));
}

- (void)tableView:(UITableView *)tableView performAction:(SEL)action forRowAtIndexPath:(NSIndexPath *)indexPath withSender:(id)sender
{
    if (action == @selector(copy:))
    {
        UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
        UIPasteboard *pasteBoard = [UIPasteboard generalPasteboard];
        [pasteBoard setString:cell.textLabel.text];
    }
}
