问题 I can't find a solution on my problem because all other posts at stackOverflow refer to UITextField created with the IDE and not programmatically. I have a custom UITextField created inside (void)viewDidLoad .I have this created programmatically so i can access the leftView property. UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(10, 66, screenAdj, 30)]; textField.borderStyle = UITextBorderStyleRoundedRect; textField.font=[UIFont fontWithName:@"Helvetica" size:14];

问题 I had this function to move certain textfields upwards, when the keyboards would block their view - I'm sure you all know about this: override func viewDidLoad() { super.viewDidLoad() let center: NotificationCenter = NotificationCenter.default center.addObserver(self, selector: #selector(keyboardDidShow(notification:)), name: NSNotification.Name?.UIKeyboardDidShow, object: nil) center.addObserver(self, selector: #selector(keyboardWillHide(notification:)), name: NSNotification.Name?

问题 In my UITableView, each row has a text field or switch as its accessory view (a bit like the Settings app). The textFields are set with Auto-capitalisation ON. But the auto-correct prompt (the one you tap to dismiss the suggestion) seems to react to finger presses up to 65 px below the actual textField! This means, for example, if a user types something in a textField, and then tries to press a UISwitch in the row below (without pressing return), instead of pressing the switch, their first

问题 I am using a table view controller to display content. I am trying to make an editable UITextField, but it is not editable. I can get them to display in each cell, but when I tap on them they aren't editable. I am also trying to store what the user enters in each cell. Please ignore the commented out parts. Here is my code: override func numberOfSections(in tableView: UITableView) -> Int { return 1 } override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int

问题 I have a UITextField that receives numeric input from the user in my application. The values from this textfield then get converted into currency format using NSNumberFormatter within my shouldChangeCharactersInRange delegate method. When I enter the number "12345678", the number gets correctly converted to $123456.78 (the numbers are entered one digit at a time, and up to this point, everything works smoothly). However, when I enter another digit after this (e.g. 9), rather than displaying

问题 I have a TabBarController with two tabs; first is InputViewController and second one is TableviewController . Input view controller has two text fields when I enter the text, after that I want to receive that text filed value in to TableviewController (in the next tab).

问题 I am attempting to create a collection of UITextField elements. I'd like the next button on the keyboard to skip to the next field and if that field is hidden from view by the keyboard, scroll it into view. This is my attempt. It works apart from 1 aspect. When dismissing the keyboard and then selecting another (or the same) field, the text input is partially hidden by the keyboard (see attached gif). The meat and potatoes is within the ViewController extension. class ViewController:

问题 I'm trying to pass text form one TextField to another TextField. Both of them are located in different ContainerViews. Users can switch between different ContainerViews by Segmented Control (thus, all my ContainerView are located inside of the ViewController with Segmented Control). I tried to do this with delegation: whenever text in TextFieldOne change, this changing should affect on another textField, so, I tried to use action on TextField in first container with Event "Value Changed":
