Make keyboard disappear with textField and textView - ios

Question

I'd like to dismiss the keyboard with a text field using
- (BOOL)textFieldShouldReturn:(UITextField *)textField {, but I need to do the same with a text view, so I'll use - (BOOL)textViewShouldReturn:(UITextView *)textView {. Is it possible to put them togheter in the same AppDelegate?
Thank you.

Answer 1

Yes, you can have two delegates
#interface ViewController : UIViewController<UITextFieldDelegate,UITextViewDelegate>
Unfortunately
The protocol UITextViewDelegate does not have, something like this.
- (BOOL)textViewShouldReturn:(UITextView *)textView {
UITextViewDelegate Protocol,
EDIT 1 :
Button press event to hide the keyboard.
-(IBAction) yourButtonPressed:(id)sender;{
for(UIView *v in self.view.subviews){
if([v isKindOfClass:[UITextField class]] || [v isKindOfClass:[UITextView class]]){
if([v isFirstResponder]){
[v resignFirstResponder];
break;
}
}
}
}

Answer 2

I don't fully understand your question...
Basically you will do the following:
implement the UITextFieldDelegate and UITextViewDelegate in your
viewController
implement the methods of that delegates, you need/want
resignFirstResponder / endEditing of the textField / textView, where
ever you want

Answer 3

Just subscribe to the delegates from your viewController and make sure to set the delegate on those objects to your viewController.
.h
#interface YourViewController : UIViewController <UITextFieldDelegate, UITextViewDelegate>
.m
someTextField.delegate = self;
someTextView.delegate = self;
From the sound of it you just need to tie into the actions of the textField and textView. Create an IBAction and tie it to what you'd like. Then you can resignFirstResponder from that IBAction.
Use this action for both your textField and textView
- (IBAction)lowerTheText:(id)sender
{
[sender resignFirstResponder];
}

Answer 4

Yes, with a UITextView it's tricky. As I say in my book...
http://www.apeth.com/iOSBook/ch23.html#_uitextview
...on the iPad, the problem of dismissing the keyboard doesn't arise because the user can dismiss it with the button in the lower right corner of the keyboard. So this leaves only the iPhone. You will typically have an interface such that there is a Done button or similar. Look at how the Notes app solves this, for example.
The process itself is just the same: call endEditing: on the superview and whoever is first responder will cease being first responder and the keyboard will retire.

Answer 5

Yes, you can use textfield delegate and textview delegate in the same application.
TextField:
#interface ViewController : UIViewController<UITextFieldDelegate,UITextViewDelegate>
// This allocates the textfield and sets its frame (or) you can use interfaceBuild
UITextField *textField = [[UITextField alloc] initWithFrame:
CGRectMake(20, 50, 280, 30)];
textField.delegate=self;
// This method enables or disables the processing of return key
-(BOOL) textFieldShouldReturn:(UITextField *)textField{
[textField resignFirstResponder]; // this is event for hide keyboard.
return YES;
}
TextView:
// init
UITextView *textView = [[UITextView alloc] initWithFrame:
CGRectMake(20, 50, 280, 30)];
- (void)textViewDidChangeSelection:(UITextView *)textView
{
[textField resignFirstResponder]; // this is event for hide keyboard.
}
