iPhone 5中不显示键盘

Question

在iPhone 4中，它正在运行。 但在iPhone 5中，它无法正常工作

为什么不在iPhone 5中工作，任何想法？

在xib文件中，我选择了启用用户交互

-(void)hideKeyboard{
    [self.view resignFirstResponder];
}
-(BOOL)textFieldShouldBeginEditing: (UITextField *)textField

{
    UIToolbar * keyboardToolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 40)];

    keyboardToolBar.barStyle = UIBarStyleDefault;
    [keyboardToolBar setItems: [NSArray arrayWithObjects:
                                [[UIBarButtonItem alloc]initWithTitle:@"First" style:UIBarButtonItemStyleBordered target:self action:@selector(previousTextField)],

                                [[UIBarButtonItem alloc] initWithTitle:@"Last" style:UIBarButtonItemStyleBordered target:self action:@selector(nextTextField)],
                                [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil],
                                [[UIBarButtonItem alloc]initWithTitle:@"Close" style:UIBarButtonItemStyleDone target:self action:@selector(resignKeyboard)],
                                nil]];
    textField.inputAccessoryView = keyboardToolBar;

}

- (void)nextTextField {
     [self hideKeyboard ];
     UITextField * txtTeamName = (UITextField *)sender;
     [txtTeamName becomeFirstResponder];

}

Answer 1

-(BOOL)textFieldShouldBeginEditing: (UITextField *)textField

此方法需要BOOL返回。在此方法的末尾添加return YES;。
