我知道我问了一个非常常见的问题。但是在经历了很多类似的问题和文章之后我无法理解
如何在 didSelectRowAtIndexPath 委托方法中访问 UITableViewCell 中的 UITextfield。
我在下面发布我的代码。我可能不会按照预期的方式进行,虽然..
我想在 didSelectRowAtIndexPath 中制作文本字段(选定行的)[becomeFirstResponder],以便我可以在此文本字段下方显示 uiPicker。这个你能帮我吗。
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
if(self.isTableForHospital)
{
UIView *myview=[self createRowViewForHospitalTable:[customArray objectAtIndex:indexPath.row]];
myview.tag=indexPath.row;
[cell addSubview:myview];
cell.selectionStyle=UITableViewCellSelectionStyleNone;
}
else
{
cell.textLabel.text=[customArray objectAtIndex:indexPath.row];
}
}
return cell;
}
-(UIView *)createRowViewForHospitalTable:(NSString *)rowText
{
UIView *hospital_row_view=[[UIView alloc]init];
UILabel *lblRowText=[[UILabel alloc]initWithFrame:CGRectMake(0, 0, 300, 50)];
lblRowText.text=rowText;
txtDepartment=[[UITextField alloc]initWithFrame:CGRectMake(310, 0, 185, 30)];
//...rest styling for textfield goes here..
txtRole=[[UITextField alloc]initWithFrame:CGRectMake(495, 0, 185, 30)];
[hospital_row_view addSubview:lblRowText];
[hospital_row_view addSubview:txtDepartment];
[hospital_row_view addSubview:txtRole];
return hospital_row_view;
}
- (void)textFieldDidEndEditing:(UITextField *)textField { }
- (void)textFieldFinished:(id)sender{
NSString *value=@"sa";
[sender resignFirstResponder];
}
// Override to support conditional editing of the table view.
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cellSelected = [tableView cellForRowAtIndexPath: indexPath];
UIView *myview=[cellSelected.contentView viewWithTag:indexPath.row];
for(UIView *item in [myview subviews])
{
if([item isKindOfClass:[UITextField class]])
{
[item becomeFirstResponder];
}
}
}
