问题 Can someone please explain the real difference between Switch and SwitchCompat .Can I use both as toggle button. can both support lower versions of android. thanks in advance 回答1: As beardedbeast already mentioned in comment, these widgets differ from each other only by the supported API level. You can use both of them for the same purpose but not simultaneously to avoid unnecessary complication. As for known issues when using Compat widgets, there is an answer from developers.blogspot: You

问题 I recently ran into a situation where I needed to be able to check the current on/off state (NOT whether it is enabled for user interaction) of a UISwitch from within an existing bucket of XCUITests, not an XCTest, and toggle it to a pre-determined state. I had added app state restoration to an old existing app and this is now interfering with a number of existing testcases between runs that expected the UISwitches in particular default states. Unlike XCTest, within XCUITest you do not have

问题 How can I save the state of multiple switches so when the application is quit and reopened, all of the switches are not at the same state they where before I quit it. Here is my very simple code for a quick homework manager I did. // // ViewController.swift // HomeworkManager // // Created by Nate Parker on 9/2/14. // Copyright (c) 2014 Nathan Parker. All rights reserved. // import UIKit class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() // Do any

问题 This sounds trivial but I'm noticing some weirdness. I've wired up a handler for the Value Changed event of a UISwitch. What I would expect is that each time the handler is called the value of the switch would change. But that's actually not always the case. If you press the switch rapidly on/off the handler can get called consecutively with the SAME state for the switch (in my specific application this is an issue). So I'm wondering if anyone else has noticed this behavior and has figured

问题 In my UITableViewController I have a custom cell which contains a switcher which is the following: import Foundation import UIKit class SwitchCell: UITableViewCell { @IBOutlet weak var label : UILabel! @IBOutlet weak var switchEmail : UISwitch! func setEditable(canEdit:Bool) { if (canEdit) { self.switchEmail.enabled = true self.label.highlighted = false } else { self.switchEmail.enabled = false self.label.highlighted = true } } func configureCellWithSwitch(labelText:String, switchValue:Bool,

问题 I have a pair of UISwitches hooked up to a IBAction via the valueChanged event. The valueChanged event is firing fine when the switches are touched. However, if I change one of the switches programmatically it doesn't call my IBAction. - (IBAction)switchChanged:(UISwitch *)sender { if (sender == self.shippingSwitch) { if (self.shippingSwitch.on && !self.PayPalSwitch.on) { [self.PayPalSwitch setOn:YES animated:YES]; } } if (sender == self.PayPalSwitch) { if (!self.PayPalSwitch.on) { // This is

问题 When I move from one view controller to another, the switch on the first controller resets itself and does not retain its state. How can I make it save its state when come back to it after viewing other controllers? And how do I make it save its state after closing the app. I have looked at the various stackOverflow questions and responses and the apple documentation, but nothing seems to work. Here is my class for the View Controller that has the switch. class Days: UIViewController {

问题 I'm trying to print on/off when the user changes the state of my UISwitch. For example - (IBAction)toggleSwitch:(id)sender { ChannelsTableViewCell* cell = (ChannelsTableViewCell *)[sender superview].superview; NSIndexPath *indexPath = [self.tableView indexPathForCell:cell]; if (cell.localSwitch.on) { NSLog(@"On"); } } When I run this it throws an error. 2014-04-24 11:33:41.462 HRApp[3258:60b] -[UITableViewCellScrollView localTitle]: unrecognized selector sent to instance 0x19354410 2014-04-24
