Im my application when the user selects a TextField the existing text gets automatically selected when the Focus changes to the textfield. How do I hide the blue selection handles that appear?
The reason I want to automatically select the existing text is so that the user can begin typing and the textfield will automatically overwrite the existing value instead of appending to it.
I figured it out. You can set the enableInteractiveSelection property to false.

I have set the values of placeholder
self.baseURLTextField.placeholder = ServiceUrl_English;
self.paymentBaseURLTextField.placeholder = PAYMENTSERVICEURL_ENGLISH;
I just want to move the placeholder up while editing or typing in textfield. is it possible through just only storyboard? or code in Objective-C.
Not really the way you intended it. Placeholder is just a hint of what should be typed in the textField and it's supposed to be removed once text entry starts.
If you want the placeholder to "move up" I suggest you either prefill the textField with the text you want to preserve, or simply add the text at the point user starts typing in, and move the cursor to where you want the user text to start.
You can achieve this by putting a UILabel at the top of the text view then show/hide it whenever the user starts typing.
Or you can use a pod like JVFloatLabeledTextField
I have a custom framework for UITextField. For now, I want to disable two attribute as the question above but still keep the cursor show in my custom textfield. I already disable the keyboard with set the inputView = UIView(), and that successful for hide the keyboard even show the cursor inside textField.
My goal is disable both attributes like above or another for can not Select All action from my textField, but still keep the cursor available anytime.
Hope to hear the ideas from you guys. Thank a lot!
I would like to give my iPhone App user the option of whether to use a picker (i.e., scroll wheel) or keyboard to input the value of a field. I'd like it to where the current value of the field effectively displays as isolated text (i.e., as a label, with the picker and keyboard hidden). But the user can change the field's value by either (A) performing a single tap on the label to reveal the keyboard so the user can type in a different value; or (B) perform a swipe on the label to reveal the picker so the user can user the picker to change the value. This will present a very clean interface in my opinion, without the clutter of the keyboard, text field, or picker unless the user changes the value. Help?
This control doesn't exist, but a possible solution would be to add a cell under the UIPickerView (assuming your using a table form) when the "Custom" option is selected and add a text field to that cell allowing custom input. Make sure you hide the cell if the UIPickerView value changes from "Custom" to avoid user confusion.
I have a view controller that controls 2 text fields and an array that displays in a table. How would I go about keeping a button disabled until the 2 fields have at least one character and the array is not empty. I am thinking about using cocoa bindings, however I can't seem to figure out a solution.
Currently my button is binded to
BOOL buttonIsEnabled;
I use that in a notification function in order to keep the button disabled, except the button will only reenable if I call that notification function.
-(void)controlTextDidChange
This means if i make a change in an array, the button wont reenable until I re-enter text. I can't seem to figure out an alternative solution. Any suggestions? Thank you.
One solution:
bind the two text fields two two strings (say text1 and text2)
in the text field bindings check Continuously Updates Value
Add this code:
- (BOOL)buttonIsEnabled {
return (self.text1.length>0 && self.text2.length>0);
}
+ (NSSet *)keyPathsForValuesAffectingButtonIsEnabled {
return [NSSet setWithObjects:#"text1",#"text2",nil];
}
Lastly bind the buttons enabled binding to buttonIsEnabled.
Because of the Continuously Updates Value text1 or text2 will change whenever characters are added to or removed from the text fields.
And the + (NSSet *)keyPathsForValuesAffectingButtonIsEnabled method will cause a Key-Value change notification to be posted for buttonIsEnabled whenever text1 or text2 change.
You can create a custom cell, give outlets to your 2 textfields and button.
Now on cell for row at index path after filling the textfields text values, put a condition checking the length of the textfields. If length is greater than 0 you can enable the button or keep it disable.
Along with this you need to put same code in delegate method (textFieldDidChange) of textfield. So that when ever new text is entered the button gets enable or disabled.
I am writing an iPhone app with a keypad and two TextFields on a single view. The user types into each of the text fields. Because I want to use an on-screen keypad, I disabled the the keyboard from launching when each TextField is selected. (I used the method suggested in this thread:
Disable UITextField keyboard?
So far so good EXCEPT the cursor doesn't blink in the either of the two TextFields until they are selected. If I just begin typing without selecting, the first textfield is filled. That's OK, but I would like to set the cursor flashing in that field so the user is notified that that is where the input will go unless they select the other field.
I did not create the text fields programatically. I created them with Interface builder.
How do I programatically select the desired starting text field (ideally some highlight would show up when selected). Right now I just got lucky and the field I want to be the default is the default.
How do I place the flashing cursor onto the right side of that text field.

Call [myTextField becomeFirstResponder]; this will notify the receiver that it is about to become first responder in its window. That should set the Cursor in the UITextField.
To programmatically activate a field and make it your starting text field you should use UIResponder's becomeFirstResponder method, which all UITextFields inherit from.
[textField becomeFirstResponder];
