无法导航文本框

Question

我想浏览UITextfields，但我遇到了问题，因为nextresponder始终为零，我无法理解为什么。因为导航不起作用。

我用这个方法：

- (BOOL)textFieldShouldReturn:(UITextField*)textField { 

UITableViewCell * curentCell = (UITableViewCell *)[[textField superview] superview]; 
NSIndexPath * indexPath = [tableView indexPathForCell:curentCell]; 

NSInteger nextTag; 
if (indexPath.row == 3) 
    nextTag = textField.tag + 3; 
else if (indexPath.row == 6) 
    nextTag = textField.tag + 1; 
else if (indexPath.row == 7) 
    nextTag = textField.tag + 1; 
else if (indexPath.row == 8) 
    nextTag = textField.tag + 2; 

UIResponder* nextResponder = [textField.superview viewWithTag:nextTag]; 

if (nextResponder) { 
    [nextResponder becomeFirstResponder]; 
} else { 
    [textField resignFirstResponder]; 
} 

[self deleteBarButton]; 

tableView.contentInset = UIEdgeInsetsMake(0, 0, 0, 0); 

return NO; 
} 

这里是我的方式初始化细胞：

- (void) initCells 
{ 
NSArray *topLevelObjectsProdus = [[NSBundle mainBundle] loadNibNamed:@"CellProdusAsigurareHeader" owner:self options:nil]; 
cellHeader = [topLevelObjectsProdus objectAtIndex:0]; 
UIImageView * img = (UIImageView *)[cellHeader viewWithTag:1]; 
img.image = [UIImage imageNamed:@"calculator-casco.png"]; 

NSArray *topLevelObjectsMarca = [[NSBundle mainBundle] loadNibNamed:@"CellAutovehicul" owner:self options:nil]; 
cellMasina = [topLevelObjectsMarca objectAtIndex:0]; 
UILabel * lblCell = (UILabel *)[cellMasina viewWithTag:2]; 
UIImageView * imgBgAuto = (UIImageView *)[cellMasina viewWithTag:5]; 
imgBgAuto.image =[UIImage imageNamed:@"alege-masina-portocaliu.png"]; 

lblCell.textColor = [YTOUtils colorFromHexString:ColorTitlu]; 
lblCell.text = @"Alege masina"; 

NSArray *topLevelObjectsProprietar = [[NSBundle mainBundle] loadNibNamed:@"CellPersoana" owner:self options:nil]; 
cellProprietar = [topLevelObjectsProprietar objectAtIndex:0]; 
UIImageView * imgBgProprietar = (UIImageView *)[cellProprietar viewWithTag:5]; 
imgBgProprietar.image =[UIImage imageNamed:@"alege-masina-portocaliu.png"]; 
UILabel * lblCellP = (UILabel *)[cellProprietar viewWithTag:2]; 
lblCellP.textColor = [YTOUtils colorFromHexString:ColorTitlu]; 
lblCellP.text = @"Alege proprietar"; 

NSArray *topLevelObjectsnrKm = [[NSBundle mainBundle] loadNibNamed:@"CellView_Numeric" owner:self options:nil]; 
cellNrKm = [topLevelObjectsnrKm objectAtIndex:0]; 
txtNumarKm = (UITextField *)[cellNrKm viewWithTag:2]; 
[(UILabel *)[cellNrKm viewWithTag:1] setText:@"Numar kilometri autovehicul"]; 
[(UITextField *)[cellNrKm viewWithTag:2] setKeyboardType:UIKeyboardTypeNumberPad]; 
[YTOUtils setCellFormularStyle:cellNrKm]; 

NSArray *topLevelObjectsCuloare = [[NSBundle mainBundle] loadNibNamed:@"CellView_String" owner:self options:nil]; 
cellCuloare = [topLevelObjectsCuloare objectAtIndex:0]; 
txtCuloare = (UITextField *)[cellCuloare viewWithTag:2]; 
[(UILabel *)[cellCuloare viewWithTag:1] setText:@"Culoare autovehicul"]; 
[YTOUtils setCellFormularStyle:cellCuloare]; 

NSArray *topLevelObjectscalc = [[NSBundle mainBundle] loadNibNamed:@"CellCalculeaza" owner:self options:nil]; 
cellCalculeaza = [topLevelObjectscalc objectAtIndex:0]; 
UIImageView * imgBgCalculeaza = (UIImageView *)[cellCalculeaza viewWithTag:1]; 
imgBgCalculeaza.image =[UIImage imageNamed:@"calculeaza-casco.png"]; 
UILabel * lblCellC = (UILabel *)[cellCalculeaza viewWithTag:2]; 
lblCellC.textColor = [YTOUtils colorFromHexString:ColorTitlu]; 
lblCellC.text = @"Cere oferta"; 
}

，我认为你应该通过：Responders

我注意到一两件事，从：How to navigate through textfields ?那...

All "tabbable" UITextFields are on the same parent view.

所以检查一下。

希望它对你有帮助。
