滚轮不工作（iphone）

Question

我添加了一个滚动视图，以我的观点类似以下内容：

_scrollView = [[UIScrollView alloc] initWithFrame:self.view.frame]; 
      _scrollView.contentSize = CGSizeMake(320, 600); 
      [_scrollView setUserInteractionEnabled:TRUE]; 
      [_scrollView setScrollEnabled:TRUE]; 
[container addSubview:self.scrollView]; 

但是滚动显示在屏幕上，我可以滚动，但它里面的texfields不工作。我怎样才能解决这个问题？

- (UIView *)Form 
{ 
    if (!_Form) { 
     CGRect frame = CGRectMake(0.0, kSignUpViewVisibleHeight, kDeviceWidth, 310.0); 
     UIView *container = [[UIView alloc] initWithFrame:frame]; 

     _scrollView = [[UIScrollView alloc] initWithFrame:self.view.frame]; 
     _scrollView.contentSize = CGSizeMake(320, 600); 
     [_scrollView setUserInteractionEnabled:TRUE]; 
     [_scrollView setScrollEnabled:TRUE]; 



     CGFloat y = 15.0; 
     frame = CGRectMake(15.0, y, kDeviceWidth - 2*15.0, kDefaultTextFieldHeight); 
     UITextField *field = [[UITextField alloc] initWithFrame:frame]; 
     [self.appDel.styleManager decorateTextField:field]; 
     field.placeholder = @"Email*"; 
     field.keyboardType = UIKeyboardTypeEmailAddress; 
     [container addSubview:field]; 
     self.FormEmail = field; 
     self.FormEmail.delegate = self; 
     self.FormEmail.autocapitalizationType = UITextAutocapitalizationTypeNone; 
     self.FormEmail.clearButtonMode = UITextFieldViewModeAlways; 

     CGFloat spacing = 8.0; 
     y = frame.origin.y + kDefaultTextFieldHeight + spacing; 
     frame = CGRectMake(15.0, y, kDeviceWidth - 2*15.0, kDefaultTextFieldHeight); 
     field = [[UITextField alloc] initWithFrame:frame]; 
     [self.appDel.styleManager decorateTextField:field]; 
     field.placeholder = @"Password*"; 
     field.secureTextEntry = YES; 
     [container addSubview:field]; 
     self.FormPassword = field; 
     self.FormPassword.delegate = self; 
     self.FormPassword.autocapitalizationType = UITextAutocapitalizationTypeNone; 
     self.FormPassword.clearButtonMode = UITextFieldViewModeAlways; 

     y = frame.origin.y + kDefaultTextFieldHeight + spacing; 
     frame = CGRectMake(15.0, y, kDeviceWidth - 2*15.0, kDefaultTextFieldHeight); 
     field = [[UITextField alloc] initWithFrame:frame]; 
     [self.appDel.styleManager decorateTextField:field]; 
     field.placeholder = @"Confirm Password*"; 
     field.secureTextEntry = YES; 
     [container addSubview:field]; 
     self.FormConfirmPassword = field; 
     self.FormConfirmPassword.delegate = self; 
     self.FormConfirmPassword.autocapitalizationType = UITextAutocapitalizationTypeNone; 
     self.FormConfirmPassword.clearButtonMode = UITextFieldViewModeAlways; 

     y = frame.origin.y + kDefaultTextFieldHeight + 16.0; 
     CGFloat w = (kDeviceWidth - 2 * 15.0)/2; 
     frame = CGRectMake(15.0, y, w - 2.0, kDefaultTextFieldHeight); 
     field = [[UITextField alloc] initWithFrame:frame]; 
     [self.appDel.styleManager decorateTextField:field]; 
     field.placeholder = @"First Name*"; 
     [container addSubview:field]; 
     self.FirstName = field; 
     self.FirstName.delegate = self; 
     self.FirstName.clearButtonMode =UITextFieldViewModeAlways; 

     frame = CGRectMake(15.0 + w + 2.0, y, w - 2.0, kDefaultTextFieldHeight); 
     field = [[UITextField alloc] initWithFrame:frame]; 
     [self.appDel.styleManager decorateTextField:field]; 
     field.placeholder = @"Last Name*"; 
     [container addSubview:field]; 
     self.FormLastName = field; 
     self.FormLastName.delegate = self; 
     self.FormLastName.clearButtonMode =UITextFieldViewModeAlways; 

     y = frame.origin.y + kDefaultTextFieldHeight + spacing; 
     frame = CGRectMake(15.0, y, w, kDefaultTextFieldHeight); 
     field = [[UITextField alloc] initWithFrame:frame]; 
     [self.appDel.styleManager decorateTextField:field]; 
     field.placeholder = @"Birthday"; 
     [container addSubview:field]; 
     self.FormBirthday = field; 
     self.FormBirthday.delegate = self; 

     frame = CGRectMake(15.0 + w + 5.0, y, w - 5.0, kDefaultTextFieldHeight); 
     SegmentControl *gender = [[SegmentControl alloc] initWithFrame:frame items:@[@"Boy", @"Girl"]]; 
     [container addSubview:gender]; 
     self.Formtype = gender; 

     y = frame.origin.y + kDefaultTextFieldHeight + 20.0; 
     frame = CGRectMake((container.frame.size.width - 192.0)/2, y, 192.0, 33.0); 
     UIButton *signUpButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
     signUpButton.frame = frame; 
     [signUpButton setTitle:@"Sign Up" forState:UIControlStateNormal]; 
     [self.appDel.styleManager decorateButton:signUpButton]; 
     [container addSubview:signUpButton]; 

     y = frame.origin.y + kDefaultTextFieldHeight + 8.0; 
     frame = CGRectMake((container.frame.size.width - 192.0)/2, y, 192.0, 34.0); 
     UIButton *cancelButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
     cancelButton.frame = frame; 
     [cancelButton setTitle:@"Cancel" forState:UIControlStateNormal]; 
     [self.appDel.styleManager decorateButton:cancelButton]; 
     [cancelButton addTarget:self action:@selector(cancelRegistration:) forControlEvents:UIControlEventTouchUpInside]; 
     [container addSubview:cancelButton]; 
     [container addSubview:self.scrollView]; 


     _Form = container; 
    } 
    return _Form; 
} 

我添加了需要滚动的表单。

滚动视图只滚动其子视图;您应该添加各种文本字段作为子视图_scrollView而不是container。
