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者,跳过所有中间的..加上这个键盘工具栏也没有显示在最后一个字段上。香港专业教育学院有一个存储所有textfield和textview对象的数组,并点击下一步和上一个我使用这个数组来确定哪个obj将成为第一响应者 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];}
现在这里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,当我点击任何短信时,我对textfield和textview使用 didbeginediting 函数。 这是我的功能代码
- (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领域都被滑雪,我的最后一个领域被设置为下一次按钮点击的第一响应者

您的实施是错误的。 for循环的结果, - (void)gotoNextTextfield 的最终结果将是 [textFieldsArray [21] becomeFirstResponder] 。并且很明显会跳过其他字段,当你点击下一个按钮时,你的最后一个字段将被设置为第一响应者。
