I am getting issue with iPhoneX back button image. It is not in right position as you can see in the screenshot
I am using below code for setting back image
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
UINavigationBar.appearance().backIndicatorImage = #imageLiteral(resourceName: "btn-back")
UINavigationBar.appearance().backIndicatorTransitionMaskImage = #imageLiteral(resourceName: "btn-back")
UIBarButtonItem.appearance().setBackButtonTitlePositionAdjustment(UIOffsetMake(0, -80.0), for: .default)
return true
}
}
Can anyone please explain why it's not at correct position and how to fix this ?
You can use topItem?.title for setting up Navigation title as:
Method 1:
self.navigationController?.navigationBar.topItem?.title = ""
Output:
Method 2:
let yourBackImage = UIImage(named: "back-Image")
self.navigationController?.navigationBar.tintColor = .red//.blue as you required
self.navigationController?.navigationBar.backIndicatorImage = yourBackImage
self.navigationController?.navigationBar.backIndicatorTransitionMaskImage = yourBackImage
self.navigationController?.navigationBar.topItem?.title = ""
Output:
Note: As Apple Human Interface GuideLine The navigation bar back image size should be-
75px × 75px(3x)
Sample image 3x(75 x 75)-

I am using this Github-Repo for a reavealing splash view.
I am calling it like this inside my AppDelegate:
let revealingSplashView = RevealingSplashView(iconImage: UIImage(named: "wIcon")!, iconInitialSize: CGSize(width: 120 * UIScreen.main.bounds.width / 414.0, height: 120 * UIScreen.main.bounds.width / 414.0), backgroundColor: .white)
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
revealingSplashView.startAnimation()
window?.rootViewController?.view.addSubview(revealingSplashView)
return true
}
I am facing an issue where sometimes after the animation is finished, it is not instantly transitioning to the other ViewController but showing a blank white screen.
Here is a screen-video for a better understanding.
Does anyone have an idea what can cause that?
Or is there an easy way to implement it without this repo?
You calling the revealingSplashView inside AppDelegate didFinishLaunchingWithOptions. If you check the documentation they clearly state to call it in the viewDidLoad method of your viewController. Your view has not been loaded that's why you got the delay.
Check the documentation which you linked above:
import RevealingSplashView
override func viewDidLoad() {
super.viewDidLoad()
//Initialize a revealing Splash with with the iconImage, the initial size and the background color
let revealingSplashView = RevealingSplashView(iconImage: UIImage(named: "twitterLogo")!,iconInitialSize: CGSize(width: 70, height: 70), backgroundColor: UIColor(red:0.11, green:0.56, blue:0.95, alpha:1.0))
//Adds the revealing splash view as a sub view
self.view.addSubview(revealingSplashView)
I am moving in from objective c to swift can anyone specify how to stop keyboard to hide the textfield . The problem is I have some text field in my view controller when the user click on last text field near to bottom of screen the keyboard appears and hide the textfield . is there any easy to solve this or should i have to use scroll view ?
Use this library called IQKeyboardManager:
https://github.com/hackiftekhar/IQKeyboardManager
Install pod file pod 'IQKeyboardManager’ . And in your app delegate
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
IQKeyboardManager.shared.enable = true
IQKeyboardManager.shared.enableAutoToolbar = true
IQKeyboardManager.shared.toolbarDoneBarButtonItemText = "Done”
return true
}
}
You can change the following properties of IQKeyboardManager as well
IQKeyboardManager.shared.overrideKeyboardAppearance = true
IQKeyboardManager.shared.keyboardAppearance = .dark
IQKeyboardManager.shared.toolbarBarTintColor = UIColor.cyan
IQKeyboardManager.shared.toolbarDoneBarButtonItemImage = UIImage(named: "<#T##String#>")
IQKeyboardManager.shared.shouldShowToolbarPlaceholder = false
IQKeyboardManager.shared.placeholderFont = UIFont(name: "Times New Roman", size: 20.0)
IQKeyboardManager.shared.shouldResignOnTouchOutside = true
IQKeyboardManager.shared.shouldPlayInputClicks = true //default
I am using Eureka to implement a simple form in my project. The form seems to have blue tint in the tint bar buttons above the keyboard and I am unsure how to change it.
Is there a way to make the "Done" label green like the rest of my UI?
Updated Eureka 4.3.x
You should override a variable customNavigationAccessoryView in your controller
override var customNavigationAccessoryView: (UIView & NavigationAccessory)? {
// The width might not be correctly defined yet: (Normally you can use UIScreen.main.bounds)
let navView = NavigationAccessoryView(frame: CGRect(x: 0, y: 0, width: view.frame.width, height: 44.0))
navView.barTintColor = UIColor.MaterialColors.category3
navView.tintColor = UIColor.white
return navView
}
Here you go and fix the colour of Done Label.
override NaviagtionAccessoryView Instance as navigationAccessoryView below
navigationAccessoryView.tintColor = "Your Colour"
navigationAccessoryView.backgroundColor = "Your Colour"
navigationAccessoryView.doneButton.tintColor = "Your Colour"
More Here
You can set a default tint color for all UIView instance by
UIView.appearance().tintColor = .red
appearance() is a method in UIAppearance protocol. UIView and its subclasses confirm to this protocol. You can also do
UIButton.appearance().tintColor = .green
Add the below line in AppDelegate
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool
{
self.window?.tintColor = UIColor.black // You can set it to which color you want.
return true
}
All the tint color of the whole app will be changed to the given color.
This works for me perfectly:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
NavigationAccessoryView.appearance().tintColor = /* your color here */
}
I am trying to change default text color for all labels in my app. I have tried to use UILabel.appearance().textColor, but it's not available for me. Can somebody advise what am I doing wrong? I have checked a lot of questions on SO, the latest one is this. And as per description it's available.
If I changed background color - it works. Tried to change tintColor - no effect. Why? Was it removed from UIAppearance protocol?
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {
var window: UIWindow?
var smStore: SMStore?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// UIAppearance configuring
let tintColor = UIColor.white
//let backgroundColor = UIColor(red: 5, green: 72, blue: 149, alpha: 1)
let backgroundColor = UIColor.black
// Global tintColor
window?.tintColor = tintColor
// UIViews
UIView.appearance().tintColor = tintColor
UIView.appearance().backgroundColor = backgroundColor
// UINavigationBars
UINavigationBar.appearance().tintColor = tintColor
UINavigationBar.appearance().backgroundColor = tintColor
// UITableViews
UITableView.appearance().backgroundColor = backgroundColor
UITableViewCell.appearance().backgroundColor = backgroundColor
UITableViewCell.appearance().tintColor = tintColor
// UILabels
UILabel.appearance().backgroundColor = UIColor.green
...
}
Xcode 9, Swift 4.
Just type it in. It compiles.
UILabel.appearance().textColor = .red
I am working on styling the app I'm building. I want to apply some system-wide styling (fonts) to the tab bar and then in some instances style things like colour. I'm running into two problems:
When you set any titleTextAttributes using setTitleTextAttributes:forState: on an instance of a UITabBar, it immediately ignores any titleTextAttributes set on the appearance proxy (including keys that were not set on the instance, but set on the appearance proxy).
// AppDelegate
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
UITabBarItem.appearance().setTitleTextAttributes([
NSFontAttributeName: UIFont(name: "Lato-Regular", size: 20.0)!
], forState: .Normal)
}
// Later on in a ViewController that has a UITabBar
override func viewDidLoad() {
myTabBar.setTitleTextAttributes([
NSForegroundColorAttributeName: UIColor.blueColor()
], forState: .Normal)
// Tab bar items now have blue text, but Helvetica Neue font
// We've lost the appearance proxy font (Lato-Regular)
}
In order to fix (1) I was just going to copy the titleTextAttributes from the appearance proxy and then overwrite them with whatever attributes I wanted to apply on the instance. Eg.
// AppDelegate
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
UITabBarItem.appearance().setTitleTextAttributes([
NSFontAttributeName: UIFont(name: "Lato-Regular", size: 20.0)!
], forState: .Normal)
}
// Later on in a ViewController that has a UITabBar
override func viewDidLoad() {
var attributes = UITabBarItem.appearance().titleTextAttributesForState(state) ?? [NSObject: AnyObject]()
assert(attributes.count > 0, "Could not read titleTextAttributes set on appearance proxy!")
}
This is most annoying because you can read appearance proxy values on UINavigationBar just fine.
Any ideas?
