[英]Hide UIPickerview On Done Button in UITableView
我在UITableview的每个单元格中都有UITextField,并且已将UIPickerview添加为UITextField的inputView,并在其工具栏上显示“完成”按钮
我的问题是,单击完成按钮后如何隐藏此弹出窗口(选择器+工具栏)? 并在特定单元格的文本框中显示选择器的选定值?
谢谢并恭祝安康
编辑:代码
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
PremiumProductsDescriptionCell *cell = (PremiumProductsDescriptionCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[PremiumProductsDescriptionCell alloc] initShoppingCartCellWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
}
ShopProduct *p = (ShopProduct *)[[ShopProduct GetShoppingCart] objectAtIndex:indexPath.row];
cell.Quantity.text = [NSString stringWithFormat:@"%d",p.Quantity];
UIPickerView *quantityPicker = [[UIPickerView alloc] init];
quantityPicker.dataSource = self;
quantityPicker.delegate = self;
UIToolbar *myToolbar = [[UIToolbar alloc] initWithFrame:
CGRectMake(0,0, 320, 44)];
UIBarButtonItem *doneButton =
[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone
target:self action:@selector(hideKeyBoard)];
quantityPicker.tag = indexPath.row;
[myToolbar setItems:[NSArray arrayWithObject: doneButton] animated:NO];
cell.Quantity.inputAccessoryView = myToolbar;
cell.Quantity.inputView = quantityPicker;
cell.Quantity.delegate = self;
return cell;
}
解决:我已将currentTextBox用作变量,并添加了以下方法,并在完成按钮的单击中调整了其第一响应者的大小:)
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
currentTextBox = textField;
}
UIPopOver无法从他们的班级被解雇,您需要从调用者班级将其解雇。 当用户按下完成按钮时,必须从弹出调用类中调用dismiss方法
-(void)doneButtonClikd
{ ParentClass *viewController=[ParentClass alloc]init];
[viewController dismissPopOver];
}
我认为这可以解决您的问题。
-(void)doneButtonclikd
{ [selectedTextfield resignFirstResponder];
}
不要忘记保存当前选定的文本字段。
假设您将UIPickerView
放在弹出窗口中,请按照以下步骤操作:
UIPopoverController* popover = ....
UIBarButtonItem* doneButton = ....
[doneButton addTarget:self action:@selector(closeMe)
forControlEvents:UIControlEventTouchUpInside]
// ....
- (void)closeMe
{
// Assuming popover is really a field or something...
[popover dismissPopoverAnimated:YES];
}
使用[self.view endEditing:YES]方法。
