键工具栏上的下一个按钮将最后一个字段设置为第一个响应程序，

Question

我在键盘工具栏上有两个按钮，下一个按钮总是将最后一个字段设置为我的第一个响应程序，跳过所有中间的字段。。另外，这个键盘工具栏也没有显示在最后一个字段上。我得到了一个数组，它存储了所有的textfield和textview对象，单击next和prev时，我使用这个数组来确定哪个obj将成为第一个响应者以下是我的代码。

这是我创建键盘工具栏的地方

-(void)createInputAccessoryView
 {
self.keyboardToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, self.bounds.size.width, 44)];
self.keyboardToolbar.barStyle = UIBarStyleBlackOpaque;
self.keyboardToolbar.tintColor = [UIColor clearColor];
UIButton *previousButton = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 100, 40)];
[previousButton setTitle:@"Previous" forState:UIControlStateNormal ];
[previousButton setBackgroundColor:[UIColor clearColor]];
[previousButton addTarget:self action:@selector(gotoPrevTextfield) forControlEvents:UIControlStateNormal];
UIButton *nextButton = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 100, 40)];
[nextButton setTitle:@"Next" forState:UIControlStateNormal];
[nextButton setBackgroundColor:[UIColor clearColor]];
[nextButton addTarget:self action:@selector(gotoNextTextfield) forControlEvents:UIControlStateNormal];
//_btnPrev = [[UIBarButtonItem alloc] initWithCustomView:previousButton];
//_btnNext = [[UIBarButtonItem alloc] initWithCustomView:nextButton];
_btnPrev =[[UIBarButtonItem alloc]initWithTitle:@"Previous" style:UIBarButtonItemStylePlain target:self action:@selector(gotoPrevTextfield)];
_btnNext=[[UIBarButtonItem alloc]initWithTitle:@"Next" style:UIBarButtonItemStylePlain target:self action:@selector(gotoNextTextfield)];
 [self.keyboardToolbar setItems:[NSArray arrayWithObjects:_btnPrev,_btnNext,nil] animated:NO];}

这是我创建对象数组的地方

-(void)addTextFieldObjectsToArray
 {
textFieldsArray = [[NSMutableArray alloc]initWithCapacity:22];
[textFieldsArray addObject:companyNameFieldObj];
[textFieldsArray addObject:contactPersonFieldObj];
[textFieldsArray addObject:customerPhoneFieldObj];
[textFieldsArray addObject:customerEmailFieldObj];
[textFieldsArray addObject:distributorNameFieldObj];
[textFieldsArray addObject:distributorSalespersonFieldObj];
[textFieldsArray addObject:distributorPhoneFieldObj];
[textFieldsArray addObject:distributorEmailFieldObj];
[textFieldsArray addObject:closetStandardFieldObj];
[textFieldsArray addObject:cylinderVelocityFieldObj];
[textFieldsArray addObject:cycleRateFieldObj];
[textFieldsArray addObject:operatingPressureFieldObj];
[textFieldsArray addObject:cylinderMountFieldObj];
[textFieldsArray addObject:wieghtOfRodAttachmentFieldObj];
[textFieldsArray addObject:rodAttachmentFieldObj];
[textFieldsArray addObject:sideAttchementFieldObj];
[textFieldsArray addObject:environmentConsiderationFieldObj];
[textFieldsArray addObject:ambientTempFieldObj];
[textFieldsArray addObject:quantityFieldObj];
[textFieldsArray addObject:competitorFieldObj];
[textFieldsArray addObject:currentApplicationIssuesFieldObj];
[textFieldsArray addObject:modificationRequiredTextViewObj];}

现在是我的下一个和上一个按钮代码

-(void)gotoPrevTextfield{
for(int i=1 ;i<22;i++)
{
        if([textFieldsArray [i] isFirstResponder])
        {
            [textFieldsArray[i-1] becomeFirstResponder];
            [textFieldsArray [i] resignFirstResponder];
            break;
        }
}}
 -(void)gotoNextTextfield
 {
   NSLog(@"%s","inside next Field");
for( int i=0 ;i<21;i++)
{
    if([textFieldsArray [i] isFirstResponder])
    {
        [textFieldsArray [i+1] becomeFirstResponder];
        [textFieldsArray [i] resignFirstResponder];
        break;
    }
}}

现在，当我的任意文本字段被点击时，我对文本字段和文本视图都使用didbeginediting函数。。这是我的函数代码

  - (void)textFieldDidBeginEditing:(UITextField *)textField
{
     _txtActiveField = textField;
     [self.txtActiveField setInputAccessoryView:self.keyboardToolbar];
  }}
- (void)textViewDidBeginEditing:(UITextView *)textView
{

    if ([textView isFirstResponder]) {
        _txtActiveView =textView;
        [self.txtActiveView setInputAccessoryView:self.keyboardToolbar];
    }}

最后一个对象是textview，其他对象是文本字段。请帮助我理解为什么我的所有字段都被跳过，而我的最后一个字段被设置为下一个按钮上的第一个响应者点击

Answer 2

您的实现是错误的。for循环的Coz，-(void(gotoNextTextfield的最终结果将是[textFieldsArray[21]成为FirstResponder]。很明显，它会跳过其他字段，当你点击下一个按钮时，你的最后一个字段会被设置为第一响应者。
