The easiest way to use BSKeyboardControls is to copy the files in BSKeyboardControls/ into your Xcode project.
- In Finder, navigate to your
BSKeyboardControlsdirectory - Drag the complete directory into Xcode
Wherever you want to use BSKeyboardControls import BSKeyboardControls.h like this:
#import "BSKeyboardControls.h"
Now you will have to set up BSKeyboardControls. This is done in five easy steps:
- Initialize the keyboard controls
- Set the delegate of the keyboard controls
- Add all the text fields to the keyboard controls (Order is important)
- Add the keyboard controls as the accessory view for all the text fields
- Set the delegate of all the text fields
Below is an example on how to setup the keyboard controls.
// Initialize the keyboard controls
self.keyboardControls = [[BSKeyboardControls alloc] init];
// Set the delegate of the keyboard controls
self.keyboardControls.delegate = self;
// Add all text fields you want to be able to skip between to the keyboard controls
// The order of thise text fields are important. The order is used when pressing "Previous" or "Next"
self.keyboardControls.textFields = [NSArray arrayWithObjects:self.textUsername,
self.textPassword,
self.textPasswordRepeated,
self.textFood,
self.textTVShow,
self.textMovie,
self.textBook,
self.textColor,
self.textBiography, nil];
// Set the style of the bar. Default is UIBarStyleBlackTranslucent.
self.keyboardControls.barStyle = UIBarStyleBlackTranslucent;
// Set the tint color of the "Previous" and "Next" button. Default is black.
self.keyboardControls.previousNextTintColor = [UIColor blackColor];
// Set the tint color of the done button. Default is a color which looks a lot like the original blue color for a "Done" butotn
self.keyboardControls.doneTintColor = [UIColor colorWithRed:34.0/255.0 green:164.0/255.0 blue:255.0/255.0 alpha:1.0];
// Set title for the "Previous" button. Default is "Previous".
self.keyboardControls.previousTitle = @"Previous";
// Set title for the "Next button". Default is "Next".
self.keyboardControls.nextTitle = @"Next";
// Add the keyboard control as accessory view for all of the text fields
// Also set the delegate of all the text fields to self
for (id textField in self.keyboardControls.textFields)
{
if ([textField isKindOfClass:[UITextField class]])
{
((UITextField *) textField).inputAccessoryView = self.keyboardControls;
((UITextField *) textField).delegate = self;
}
else if ([textField isKindOfClass:[UITextView class]])
{
((UITextView *) textField).inputAccessoryView = self.keyboardControls;
((UITextView *) textField).delegate = self;
}
}
Next you will have to set up the delegation methods. BSKeyboardControls requires three delegates: BSKeyboardControlsDelegate, UITextFieldDelegate and UITextViewDelegate.
First you want to close the keyboard if the user presses the "Done button".
- (void)keyboardControlsDonePressed:(BSKeyboardControls *)controls
{
[controls.activeTextField resignFirstResponder];
}
Next you want to focus the previous or the next text field whenever the user presses either the "Previous" or the "Next" button.
- (void)keyboardControlsPreviousNextPressed:(BSKeyboardControls *)controls withDirection:(KeyboardControlsDirection)direction andActiveTextField:(id)textField
{
[textField becomeFirstResponder];
}
This is all there is for the BSKeyboardControlsDelegate. Now you want to set up the UITextFieldDelegate. The only method required is - (void)textFieldDidBeginEditing:
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
if ([self.keyboardControls.textFields containsObject:textField])
self.keyboardControls.activeTextField = textField;
}
Next you set up the - (void)textViewDidBeginEditing: method of the UITextViewDelegate. This is entirely similar to the UITextFieldDelegate.
- (void)textViewDidBeginEditing:(UITextView *)textView
{
if ([self.keyboardControls.textFields containsObject:textView])
self.keyboardControls.activeTextField = textView;
[self scrollViewToTextField:textView];
}
Now you are ready to use BSKeyboardControls. For more information on how to use BSKeyboardControls, please see Example.xcodeproj.
