如何在ios中返回textfield上的键盘，同时返回tableview单元格上的textfield

Question

当我把文本字段放在单元格上时，我如何在文本字段上返回键盘。请告诉我如何解决这个问题？这是我在表格视图单元格上设置文本字段的代码

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellidentitifier = @"cell";
    UITableViewCell * cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellidentitifier];
    if (cell ==nil)
    {
        cell = [tableView dequeueReusableCellWithIdentifier:cellidentitifier];
    }
    else
    {
        [cell prepareForReuse];
    }
    UIImageView *imgview = [[UIImageView alloc]initWithFrame:CGRectMake(30, 10, 70, 70)];
    imgview.backgroundColor = [UIColor blackColor];
    [cell.contentView addSubview:imgview];
    UITextField *_nameTF = [[UITextField alloc]initWithFrame:CGRectMake(120, 10, 160, 22)];
    _nameTF.placeholder =@"Client Name";
    _nameTF.layer.borderWidth = 1.0;
    [cell.contentView addSubview:_nameTF];
    _nameTF = nil;
    UITextField *_timeTF = [[UITextField alloc]initWithFrame:CGRectMake(120, 37, 160, 22)];
    _timeTF.placeholder = @"Time";
    _timeTF.layer.borderWidth= 1.0;
    [cell.contentView addSubview:_timeTF];
    _timeTF = nil;

    UITextField *_PhoneTF = [[UITextField alloc]initWithFrame:CGRectMake(120, 64, 160, 22)];
    _PhoneTF.placeholder = @"Phone";
    _PhoneTF.layer.borderWidth= 1.0;
    [cell.contentView addSubview:_PhoneTF];
    _PhoneTF = nil;

    return cell;
}

Answer 1

在return cell语句之前，将委托设置为cellForRowAtIndexPath中的文本字段，如下所示。

_nameTF.delegate = self;
_timeTF.delegate = self;
_PhoneTF.delegate = self;

和

-(BOOL)textFieldShouldReturn:(UITextField *)textField{
    [textField resignFirstResponder];
    return YES;
}

和您的viewcontroller设置委托，如下所示在.h文件中

@interface myviewVC : UIViewController<UITextFieldDelegate>
