由 送分小仙女□ 提交于 2019-12-03 04:34:58
问题 below you'll find my .h & .m files for my primary viewcontroller. I have 3 questions. 1.) Because I have multiple uitextfields, do I have to set each with their own resignFirstResponder statement ? and 2.) where would I do that, in what method ? 3.) Is my syntax right for resigning the first responder ? Also it would be really nice if I could dismiss the keyboard when the user clicks out of the field NOT on hitting the return key! I know this has been asked and answered before, but to be

I have two textfield, in first textfield I write "Hello" and when I push enter in iPad keyboard, I want that in second textfield appear "World"; How can I use enter to create an action in my application? You would typically assign your view controller as the text field's delegate and then implement the textFieldShouldReturn: method, e.g.: - (BOOL)textFieldShouldReturn:(UITextField *)textField { otherTextField.text = @"World" return YES; } You can do that by implementing the UITextFieldDelegate protocol in your controller. For instance you could do something like: - (BOOL)textFieldShouldReturn:

How to make a UIScrollView auto scroll when a UITextField becomes a first responder

由 爷，独闯天下 提交于 2019-12-03 04:14:20
问题 I've seen posts around here that suggest that UIScrollViews should automatically scroll if a subview UITextField becomes the first responder; however, I can't figure out how to get this to work. What I have is a UIViewController that has a UIScrollView and within the UIScrollView there are multiple textfields. I know how to do this manually if necessary; however, from what I've been reading, it seems possible to have it autoscroll. Help please. 回答1: I hope this example will help you You can

How to set letter spacing of UITextField

问题 I have an app in which the user has to type a four digit pin code. All digits have to be at a set distance from each other. Is there a way to do this if the PinTextField is a subclass of UIView ? I know in a ViewController you could use UITextFieldTextDidChangeNotification and set the attributed text for each change. Notifications don't seem to work in a UIView though. Also I was wondering if there isn't a simpler way than making an attributed string for every update if you want to set the

问题 I am trying to apply NSAttributedString styles to a UITextField after processing a new text entry, keystroke by keystroke. The problem is that any time I replace the text the cursor will jump the very end on each change. Here's my current approach … Receive and display text change immediately (same issue applies when I return false and do the text replacement manually) func textField(textField: UITextField!, shouldChangeCharactersInRange range: NSRange, replacementString string: String!) ->

Clear UITextField Placeholder text on tap

由 一世执手 提交于 2019-12-03 03:13:47
问题 In Xcode4 I've created some placeholder text for a UITextField and I'd like it to clear when the user taps in the box. So, in the Attributes Inspector for the text field I've clicked "Clear when editing begins" however this does not immediately remove the text when I tap in the text box (it only disappears when you start typing). Is there any way of removing the placeholder text immediately on tapping in the text box? 回答1: make your ViewController the delegate of the textField and implement

Cannot remove border of UITextField dynamically

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: I want to remove the border of UITextField dynamically. I tried [stringTextField setBorderStyle:UITextBorderStyleNone]; but nothing happened. Any idea? 回答1: Is the TextField already displayed in the view when this happens? If so, you (probably) need to execute the following: [stringTextField setBorderStyle:UITextBorderStyleNone]; [stringTextField setNeedsDisplay]; in order for the view to redraw the TextField , sans border. Note that there's no guarantee the system will immediately redraw the textField . You're indicating to the system that

How to scroll view up when keyboard appears?

由 五迷三道 提交于 2019-12-03 03:03:01
问题 I know that this question has been asked over and over again, but nothing seems to be working for me. Most of the solutions around are pretty out of date, and the rest are incredibly huge blocks of code that are ten times larger then the actual projects coding. I have a few UITextFields lined up vertically, but when the keyboard launches to edit one, it covers up the text field. I was wondering if there is a simple beginner way to scroll the view up, and then back down when the editing starts
