问题 i tried many ways to change keyboard in ipad programmatically but it doesn't change at all . i cant find any property in uitext for doing this. any idea? 回答1: Unfortunately, you cannot control the language of the keyboard.

问题 I have two problems at UIDatePicker as inputView. 1: When I select "April 17 9 00 PM" in datePicker, dateTextField outputs "2014-04-107 21:00:00". 2: UTC of My country is +0900.

问题 Is there any easy way to set a text field's hint to italic, while keeping the actual text non-italicized? The image below shows what I'm trying to accomplish, but doesn't actually work, as text typed into the first text field is still italicized.

This would work, right? Is there a better way? 回答1: Try this: UIFont*

问题 I'm wondering how to disable the inputview of a UITextfield. Setting textField.inputView = nil; or [textField setInputView:nil] in ShouldBeginEditing doesn't do anything, and using the userInteraction property removes the ability to interact with the field. Ideally, I'd like to remove both the cursor and the keyboard while still being able interact with and switch between textfield methods, using ShouldBeginEditing and ShouldEndEditing. Is there any way to accomplish this? 回答1: You should do

问题 UITextField and UITextView both adopt the UITextInput protocol. UITextView's selectedRange property returns NSRange, where UITextField doesn't have any selection properties/methods. I'd like to use one routine to manage insertion in either UITextField or UITextView. So I do the following: id<UITextInput> textInput = nil; if ([self.aTextView isFirstResponder]) { textInput = self.aTextView; } else if ([self.aTextField isFirstResponder]) { textInput = self.aTextField; } if (textInput != nil) {

问题 I've been trying to animate a change in UIEdgeInsets . I've already tried using UIView.animateWithDuration and the insets just jump to the final values. Does anyone know if this a property that can't be animated? Or better yet, is anyone aware of a way to animate insets? As an example: // Starting inset values self.searchField.placeHolderInset = UIEdgeInsets(top: 0, left: 110, bottom: 0, right: 10) // Animation block UIView.animateWithDuration(0.1, animations: { self.searchField

问题 So first, I needed to set the placeholder text color, so I subclassed the UITextfield as shown in several stack overflow posts. This works fine. Here is an example post of this: How do I subclass UITextField and override drawPlaceholderInRect to change Placeholder color.
