hiding keyboard ios [duplicate]

问题:

This question already has an answer here:

• Dismiss keyboard on touch anywhere outside UITextField 8 answers

I have a few text inputs and I can hide the keyboard whenever I touch the background, but only when I have been entering into the first text box name textField1. now this code should be simple but I just can't seem to get it.

-(IBAction)backgroundTouched:(id)sender {
    [textField1 resignFirstResponder];
    [buildLength resignFirstResponder];
    [buildWidth resignFirstResponder];
    [ridgeWidth resignFirstResponder];
    [rafterWidth resignFirstResponder];
    [hipWidth resignFirstResponder];
    [eaveOverhang resignFirstResponder];
    [spacing resignFirstResponder];
}

回答1:

If you want to hide the keyboard when you tap a button and you have more than one UITextFields in your view, then you should use:

[self.view endEditing:YES];

Tap anywhere on the view, and the keyboard will disappear.

Try this:

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
{
     [[self view] endEditing:YES];
}

You can also iterate through an array of views (such as your UIView's subviews) and manually resign the keyboard, this is good if you dont want to resign on ALL the subviews within your parent UIView.

- (void)viewDidLoad
{
    self.view.userInteractionEnabled = TRUE;
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
    //Iterate through your subviews, or some other custom array of views
    for (UIView *view in self.view.subviews)
        [view resignFirstResponder];
}

You can try UITouch method, and in this set your text field object and call resignFirstResponder when ever you touch on the screen the keyboard will resign, I hope this will work for you.

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{  
    [currentSelectedTextField resignFirstResponder];
}
