IOS - Issues with UITextField Inside A Toolbar - ios

Question

I have a UIToolbar that I have programatically created that has a UITextField and UIButton added to it as separate subviews. The code below shows the method which creates the UIToolbar and returns the UIView.
- (UIToolbar *)createToolbar
{
//set background of toolbar
UIImage *rawBackground = [UIImage imageNamed:#"toolbarBackground.png"];
UIImage *toolBarBackground = [rawBackground stretchableImageWithLeftCapWidth:13 topCapHeight:22];
createPostBar = [[UIToolbar alloc] init];
createPostBar.frame = CGRectMake(0, 0, self.view.frame.size.width, 44);
[createPostBar setBackgroundImage:toolBarBackground forToolbarPosition:UIToolbarPositionAny barMetrics:UIBarMetricsDefault];
//add and syle all toolbar items
textView = [[HPGrowingTextView alloc] initWithFrame:CGRectMake(5, 6, 270, 40)];
textView.contentInset = UIEdgeInsetsMake(0, 5, 0, 5);
textView.minNumberOfLines = 1;
textView.maxNumberOfLines = 6;
textView.returnKeyType = UIReturnKeyDefault;
textView.font = [UIFont systemFontOfSize:15.0f];
textView.textColor = [UIColor blackColor];
textView.text = #"";
textView.delegate = self;
textView.internalTextView.scrollIndicatorInsets = UIEdgeInsetsMake(0, 0, 0, 0);
textView.backgroundColor = [UIColor whiteColor];
UIImage *postBtnBackground = [UIImage imageNamed:#"postButton.png"];
UIImage *rawEntryBackground = [UIImage imageNamed:#"postFieldBackground.png"];
UIImage *entryBackground = [rawEntryBackground stretchableImageWithLeftCapWidth:13 topCapHeight:22];
toolbarOverlay = [[UIImageView alloc] initWithImage:entryBackground];
toolbarOverlay.frame = CGRectMake(4, 0, 278, 44);
UIButton *postButton = [UIButton buttonWithType:UIButtonTypeCustom];
[postButton addTarget:self
action:#selector(btnEdit:)
forControlEvents:UIControlEventTouchDown];
[postButton setBackgroundImage:postBtnBackground forState:UIControlStateNormal];
postButton.frame = CGRectMake(280, 5, 35.0, 35.0);
[createPostBar addSubview:textView];
[createPostBar addSubview:toolbarOverlay];
[createPostBar addSubview:postButton];
createPostBar.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin;
return createPostBar;
}
I then add the UIToolbar to a UITextField as its accessory view when the text field is clicked.
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
if (textField.tag <= 2)
{
textField.inputAccessoryView = [self createToolbar];
}
}
When the text field is clicked the keyboard pops up with the toolbar. Rate now the text field in the toolbar allows you to change the text of the text field that was clicked. Rate now when the text field is clicked the curser stays with in the clicked text field.
How can I make it so that the curser moves to the UITextField in the toolbar when the text field is clicked and no the original text field. Also, how do I disable editing of the text in the text field? I tried disabling user interactions but that made it so the text field was no longer clickable.

You probably shouldn't be using a text field to show your data, use a label instead (with a gesture recognizer).
To show your keyboard, don't use an accessory view, just add the toolbar as a subview and make the text field the first responder.
If you try to do it the way you describe it won't work because the accessory view will be removed when the original text field is no longer the first responder.
Finally, think about maybe using an alert view with a text field instead...
