func taskViewController(_ taskViewController: ORKTaskViewController, stepViewControllerWillAppear stepViewController: ORKStepViewController) {
let backgroundImage = UIImage(named: "setting_background_new")
let imageView = UIImageView(image: backgroundImage)
imageView.frame = CGRect(x: 0, y: 0, width: 100, height: 200)
UIView.appearance(whenContainedInInstancesOf: [ORKTaskViewController.self]).addsubview(imageview)
}
its crash because of 'Can't add self as subview' and i also try other methods and see some links but cant get to set background image answer,there is only answer of set background colors but i want to add background image in taskviewController.

I am trying to set image inside the textfield , and for that i am creating an image view in code but when i am trying to adjust its width and height via CGRect(x:int, y:int, width:int, height:int) , its not being applied and the image size is still original. I ve seen so many tutorials for putting image in text field and all of them are using CGRect and its working for them, as size of image gets what they apply in CGRect, but not for me. Below is the code i m trying to use. Image is also attached. Textfield style is rounded (Default) and icon size is 50px.
UIViewController
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var email: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
update()
// Do any additional setup after loading the view.
}
func update() {
email.leftViewMode = .always
let imageview = UIImageView()
let image = UIImage(named: "icon")
imageview.image = image
imageview.frame = CGRect(x: 15, y: 0, width: 50 , height: 50)
email.leftView = imageview
}
}
Also, i ve tried to change 'Render as' to 'template' in image assets but its still not working.
Hey I’ve tried to do it programmatically and it works for me. Quickly drafted it on iPad playgrounds. Try this:
class Test: UIViewController {
let lable = UITextField()
let image = UIImage()
override func viewDidLoad() {
super.viewDidLoad()
self.view.backgroundColor = .white
lable.frame = CGRect(x: 200, y: 200, width: 300 , height: 50)
lable.backgroundColor = .black
update()
self.view.addSubview(lable)
}
func update() {
lable.leftViewMode = .always
let imageview = UIImageView()
let image = UIImage(systemName: "icloud")
imageview.image = image
imageview.frame = CGRect(x: 15, y: 0, width: 50 , height: 50)
lable.leftView = imageview
self.view.addSubview(imageview)
}
}
I have an UITextField component which has an icon on the right side of it. Icon is just an UIImageView. I'm trying to give inset to UIImageView with below code
imageView.image = UIImage(named: "example")?.withAlignmentRectInsets(UIEdgeInsets(top: -4, left: 0, bottom: -4, right: 0))
However, It doesn't work cuz It's frame hasn't been set when setting Its' Image. I'm giving Its frame with below code;
iconImageView.frame = CGRect(
x: bounds.size.width - iconWidth - iconMarginLeft,
y: bounds.size.height - textHeight() - iconMarginBottom,
width: iconWidth,
height: textHeight()
)
and how I setup UIImageView
fileprivate func createIconImageView() {
let iconImageView = UIImageView()
iconImageView.backgroundColor = .clear
iconImageView.contentMode = .scaleAspectFill
iconImageView.autoresizingMask = [.flexibleTopMargin, .flexibleRightMargin]
if (hasToolTip) {
let tapGesture = UITapGestureRecognizer(target: self, action:#selector(toolTipTapped(_:)))
iconImageView.addGestureRecognizer(tapGesture)
iconImageView.isUserInteractionEnabled = true
let image = UIImage(named: "infotooltip")
image?.accessibilityIdentifier = "tooltipImage"
iconImageView.image = image!
changeIconAlphaToOne()
self.iconImageView = iconImageView
} else {
self.iconImageView = iconImageView
changeIconAlphaToZero()
}
addSubview(iconImageView)
}
My problem is that, I need to give UIEdgeInset to the image. However, because I'm trying to give it before setting the frame, It doesn't work. How can I achieve this?
I also try to resize the image by referencing below post but doesn't work for me. I also DO NOT want to put it inside a content view which will make my component class more complicated.
The simplest way to resize an UIImage?
I am using xcode8.3 and Swift3 in my project.
I have a UITextField in storyboard, I created a IBOutlet in corresponding controller class:
#IBOutlet weak var myTextField: UITextField!
I would like to show a small image on the right side inside the text field, I found a solution here (though it shows image on left side).
THis is what I tried:
override func viewDidLoad() {
super.viewDidLoad()
let imageView = UIImageView();
let image = UIImage(named: "my_icon");
imageView.image = image;
self.myTextField.rightView = imageView
self.myTextField.rightViewMode = .always
}
(In xcode Assets.xcassets folder I have my_icon.png, my_icon#2x.png, my_icon#3x.png)
When I run the code on iPhone, I don't see my_icon showing anywhere in UITextField. I also tried to add the ".png" suffix when loading image let image = UIImage(named: "my_icon.png");, it doesn't help either.
Why the solution in the link doesn't work for me?
I had similar issue, it sounds funny but it can cause the issue. I believe your imageView's frame is 0.
So
let imageView = UIImageView();
let image = UIImage(named: "my_icon");
imageView.image = image;
imageView.frame = CGRect(x: 0, y: 0, width: imageView.intrinsicContentSize.width, height: imageView.intrinsicContentSize.height)
self.myTextField.rightView = imageView
self.myTextField.rightViewMode = .always
Set frame:
imageView.frame = CGRect(x: 0, y: 0, width: 20, height: 20)

Closed 6 years ago.
I want to display one view when it is in portrait mode, and another view in landscape mode. Is it possible? I tried this code but view is overlapping. How to fix it?
override func didRotateFromInterfaceOrientation(fromInterfaceOrientation: UIInterfaceOrientation) {
let app = UIApplication.sharedApplication()
if (app.statusBarOrientation.isLandscape)
var imageView : UIImageView
imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 1300
, height: 50))
imageView.contentMode = UIViewContentMode.ScaleToFill
// UIGraphicsBeginImageContext(self.view.frame.size)
imageView.image = UIImage(named:"Header")
self.view.addSubview(imageView)
UIGraphicsBeginImageContext(self.view.frame.size)
UIImage(named: "Landscape")?.drawInRect(self.view.bounds)
let image: UIImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
self.view.backgroundColor = UIColor(patternImage: image)
display1()
if (app.statusBarOrientation.isPortrait)
var imageView : UIImageView
imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 800
, height: 50))
imageView.contentMode = UIViewContentMode.ScaleToFill
// UIGraphicsBeginImageContext(self.view.frame.size)
imageView.image = UIImage(named:"Header")
self.view.addSubview(imageView)
UIGraphicsBeginImageContext(self.view.frame.size)
UIImage(named: "background")?.drawInRect(self.view.bounds)
let image: UIImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
self.view.backgroundColor = UIColor(patternImage: image)
print(String.self, "sandeep potrait")
displayKeyboard()
You need to hide or remove the view that you don't want to see in current orientation.
To do that you need to create properties for these views and something like:
var portraitImageView: UIImageView?
var landscapeImageView: UIImageView?
func ... {
if (app.statusBarOrientation.isLandscape) {
var imageView: UIImageView
...
self.view.addSubview(imageView)
self.landscapeImageView = imageView
self.portraitImageView.removeFromSuperview()
self.portraitImageView = nil
} else {
...
}
}
I can set an image to my TableView background, but the image is in the center of the view.
How can I set the image to top ?
I'm using staticTableView
let image = UIImageView(image: UIImage(named: "img.jpg"))
self.settingsTableView.backgroundView = image
self.settingsTableView.backgroundView?.frame = CGRectZero
self.settingsTableView.backgroundView?.contentMode = UIViewContentMode.ScaleAspectFit
If you're using a static table and theres no chance of changing it you might want to take an approach like this:
override func viewDidLoad() {
super.viewDidLoad()
//Create the UIImage
let image = UIImage(named: "testing")
//Create a container view that will take all of the tableView space and contain the imageView on top
let containerView = UIView(frame: CGRect(x: 0.0, y: 0.0, width: self.view.bounds.width, height: self.view.bounds.height))
//Create the UIImageView that will be on top of our table
let imageView = UIImageView(frame: CGRect(x: 0.0, y: 0.0, width: self.view.bounds.width, height: image!.size.height))
//Set the image
imageView.image = image
//Clips to bounds so the image doesnt go over the image size
imageView.clipsToBounds = true
//Scale aspect fill so the image doesn't break the aspect ratio to fill in the header (it will zoom)
imageView.contentMode = UIViewContentMode.ScaleAspectFit
containerView.addSubview(imageView)
self.tableView.backgroundView = containerView
}
Make the cells or the headers transparent as you wish. I don't know how your UI should work. This method WON'T scroll the imageView but you can simply do it in the scrollView delegate method. Let me know if you need it to scroll and I'll help you out
