Turn on Shift key when spacebar is pressed in UITextField

• How do I programmatically turn on the shift key (so that the next character is uppercase) on the keyboard when the user presses the spacebar for a UITextField? In addition, I do not want any spaces in the text field such that the user is able to type an entry like this: "ThisIsATest" I currently use the following to detect if the spacebar is pressed, and return false to avoid spaces, but I dont know how to toggle the shift key: // check if string in UITextField is a space if (string == " "){ // do not return a space return false }

  UPDATED ANSWER This is tested and does print "ThisIsATest" when you press space bar after each word. I'm not that good with Swift yet, so this snippet is in Obj-C. It's pretty straightforward. Be sure to set your textField's delegate to ViewController either in code or in IB. #import "ViewController.h" @interface ViewController () <UITextFieldDelegate> @property (nonatomic, assign) BOOL shouldCapitalizeNextChar; @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; self.shouldCapitalizeNextChar = YES; } - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { if ([string isEqualToString:@" "]) { self.shouldCapitalizeNextChar = YES; return NO; } if (self.shouldCapitalizeNextChar) { NSString *capitalizedChar = [string capitalizedString]; textField.text = [textField.text stringByAppendingString:capitalizedChar]; self.shouldCapitalizeNextChar = NO; return NO; } return YES; } @end As before, this won't work with copied and pasted text. But it should help you to get the idea. ORIGINAL ANSWER A UITextField knows how to autocapitalize each word, if that's what you want in your app just use: Obj-c textField.autocapitalizationType = UITextAutocapitalizationTypeWords; Swift textField.autocapitalizationType = UITextAutocapitalizationType.Words Be aware that this is just a suggestion to the user, he/she can override it by pressing shift. It won't work if Paste option is used either.
