copied!<p>I created a simple view based project in XCode and the following works for me. I didn't add Facebook to the mix but the UITextField should simulate it. What this does is:</p> <ol> <li><p>Touching the UIButton or shaking the device will toggle editing of the UITextField including showing/hiding the keyboard</p></li> <li><p>The UILabel <code>statusLabel</code> will display the last touch or shake action and then timeout to display the default text.</p></li> </ol> <p>You can create a similar project and copy/paste this in or try to work with your existing app.</p> <p>EDITED TO ADD .H FILE</p> <p>Header:</p> <pre><code>// ShakeShakeShakeViewController.h #import <UIKit/UIKit.h> @interface ShakeShakeShakeViewController : UIViewController { UITextField * _textField; UILabel * _statusLabel; UIButton * _actionButton; } @property (nonatomic, retain) IBOutlet UITextField * textField; @property (nonatomic, retain) IBOutlet UILabel * statusLabel; @property (nonatomic, retain) IBOutlet UIButton * actionButton; - (IBAction)userInvokedActionWithControl:(id)sender; - (void)resetStatusLabel; - (void)toggleTextFieldEditing; @end </code></pre> <p>Source:</p> <pre><code>// ShakeShakeShakeViewController.m #import "ShakeShakeShakeViewController.h" @implementation ShakeShakeShakeViewController @synthesize textField = _textField, statusLabel = _statusLabel, actionButton = _actionButton; - (void)dealloc { self.textField = nil; self.statusLabel = nil; self.actionButton = nil; [super dealloc]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } #pragma mark - View lifecycle - (void)viewDidLoad { [self resetStatusLabel]; } - (void)viewDidUnload { [super viewDidUnload]; self.textField = nil; self.statusLabel = nil; self.actionButton = nil; } - (void)viewDidAppear:(BOOL)animated { [self becomeFirstResponder]; } - (IBAction)userInvokedActionWithControl:(id)sender { NSLog(@"Touched"); self.statusLabel.text = @"Touched"; [self toggleTextFieldEditing]; } - (BOOL)canBecomeFirstResponder { return YES; } - (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event { if (motion != UIEventSubtypeMotionShake) return; NSLog(@"Shaking..."); self.statusLabel.text = @"Shaking..."; } - (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event { if (motion != UIEventSubtypeMotionShake) return; NSLog(@"Done shaking..."); self.statusLabel.text = @"Done shaking"; [self toggleTextFieldEditing]; } - (void)toggleTextFieldEditing { if ([self.textField isFirstResponder]) { [self becomeFirstResponder]; } else { [self.textField becomeFirstResponder]; } [self performSelector:@selector(resetStatusLabel) withObject:nil afterDelay:2]; } - (void)resetStatusLabel { self.statusLabel.text = @"Shake me"; } @end </code></pre>
