textFieldShouldEndEditing 不显示 Next / Done 按钮键盘

Question

我无法使用“下一步”或“完成”浏览表单文本字段。我尝试将UITextFieldDelegate 添加到我的UIViewController 并委托我的UITextField。我尝试根据this post修改我的代码，但还是不行。

UIViewController.h

@interface MyViewController : UIViewController<UITextFieldDelegate, UIAlertViewDelegate> {
   @property (nonatomic, strong) UITextField *usernameTextfield;
   @property (nonatomic, strong) UITextField *passwordTextfield;
}

UIViewController.m

@implementation MyViewController
@synthesize usernameTextfield, passwordTextfield;

   self.usernameTextfield = [[UITextField alloc] initWithFrame:CGRectMake(10,25, SCREEN_WIDTH-20, 35)];
   self.usernameTextfield.delegate = self;

   self.passwordTextfield = [[UITextField alloc] initWithFrame:CGRectMake(10,95, SCREEN_WIDTH-20, 35)];
   self.passwordTextfield.secureTextEntry = TRUE;
   self.passwordTextfield.delegate = self;

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
   if (textField == self.passwordTextfield) {
       [textField resignFirstResponder];
   } else if (textField == self.usernameTextfield) {
       [self.passwordTextfield becomeFirstResponder];
   }
   return YES;
}

欢迎任何想法。提前致谢！
