每次我尝试将数组发送到此自定义tableview单元时，该数组都不发送（如array.count = 0所示，而它应该是9）。
这是我的public void CloseNotepad()
{
IntPtr hWnd = IntPtr.Zero;
using (Process p = Process.GetProcessesByName("notepad").FirstOrDefault()) {
hWnd = p.MainWindowHandle;
}
if (hWnd == IntPtr.Zero) return;
var window = GetMainWindowElement(hWnd);
var menuBar = GetWindowMenuBarElement(window);
var fileMenu = GetMenuBarMenuByName(menuBar, "File");
if (fileMenu is null) return;
// var fileSubMenus = GetMenuSubMenuList(fileMenu);
bool result = InvokeSubMenuItemByName(fileMenu, "Exit", true);
}
private AutomationElement GetMainWindowElement(IntPtr hWnd)
=> AutomationElement.FromHandle(hWnd) as AutomationElement;
private AutomationElement GetWindowMenuBarElement(AutomationElement window)
{
var condMenuBar = new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.MenuBar);
var menuBar = window.FindAll(TreeScope.Descendants, condMenuBar)
.OfType<AutomationElement>().FirstOrDefault(ui => !ui.Current.Name.Contains("System"));
return menuBar;
}
private AutomationElement GetMenuBarMenuByName(AutomationElement menuBar, string menuName)
{
var condition = new AndCondition(
new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.MenuItem),
new PropertyCondition(AutomationElement.NameProperty, menuName)
);
if (menuBar.Current.ControlType != ControlType.MenuBar) return null;
var menuItem = menuBar.FindFirst(TreeScope.Children, condition);
return menuItem;
}
private List<AutomationElement> GetMenuSubMenuList(AutomationElement menu)
{
if (menu.Current.ControlType != ControlType.MenuItem) return null;
ExpandMenu(menu);
var submenus = new List<AutomationElement>();
submenus.AddRange(menu.FindAll(TreeScope.Descendants,
new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.MenuItem))
.OfType<AutomationElement>().ToArray());
return submenus;
}
private bool InvokeSubMenuItemByName(AutomationElement menuItem, string menuName, bool exactMatch)
{
var subMenus = GetMenuSubMenuList(menuItem);
AutomationElement namedMenu = null;
if (exactMatch) {
namedMenu = subMenus.FirstOrDefault(elm => elm.Current.Name.Equals(menuName));
}
else {
namedMenu = subMenus.FirstOrDefault(elm => elm.Current.Name.Contains(menuName));
}
if (namedMenu is null) return false;
InvokeMenu(namedMenu);
return true;
}
private void ExpandMenu(AutomationElement menu)
{
if (menu.TryGetCurrentPattern(ExpandCollapsePattern.Pattern, out object pattern))
{
(pattern as ExpandCollapsePattern).Expand();
}
}
private void InvokeMenu(AutomationElement menu)
{
if (menu.TryGetCurrentPattern(InvokePattern.Pattern, out object pattern))
{
(pattern as InvokePattern).Invoke();
}
}
：
cell.h @interface Scell : UITableViewCell
...
@property (nonatomic, strong) NSMutableArray *lineInfo;
@end
：
cell.m这是我尝试发送数据的地方。
@implementation Scell
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self)
{
self.lineInfo = [[NSMutableArray alloc]init];
//set up labels here, etc.
NSLog(@"Lines count: %li", self.lineInfo.count);
}
return self;
}
：
setup.m有人知道为什么不发送吗？ setup.m中的NSLog显示9，但Scell中的NSLog显示0。
答案 0 :(得分：0)
在cell.m中，初始化单元格时将打印行数，因此当时该数组中没有值，这就是为什么它打印零的原因。
从setup.m中的cellForRowAtIndexPath中，将temp的lineInfo分配给单元格的lineInfo属性。因此，因此cellForRowAtIndexPath打印正确的计数，但是initWithStyle显示为0。
希望这会有所帮助。
