我可以隐藏第一个 texbox 的键盘，但不能隐藏 ios 中的第二个文本框

Question

您好，我正在尝试在键入时隐藏键盘。我已经成功完成了第一个文本框的代码，即 username_textbox，但是当我为第二个文本框（即密码文本框）执行相同的代码时，键盘不会隐藏。

谁能帮我解决当有多个文本框时如何隐藏键盘的问题。

我的代码是：

ViewController.h

//@interface ViewController : UIViewController
//
//@end


@interface ViewController : UIViewController<UITextFieldDelegate>

@property (strong, nonatomic) IBOutlet UITextField *usernameTextbox;

@property (strong, nonatomic) IBOutlet UITextField *passwordTextbox;

@end

ViewController.m

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    [[self navigationController]setNavigationBarHidden:YES animated:YES ];

    [self.usernameTextbox setDelegate:self];
    [self.passwordTextbox setDelegate:self];

}

-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [self.usernameTextbox resignFirstResponder];
       return YES;
}

-(BOOL)textField2ShouldReturn:(UITextField *)textField
{
    [self.passwordTextbox resignFirstResponder];
    return YES;
}

Answer 1

试试这个

-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
    // [self.usernameTextbox resignFirstResponder];
    // [self.passwordTextbox resignFirstResponder];
    [self.view endEditing:YES];
    return YES;
}
