I'm making a message when the TableView is empty, this is code :
let emptyLabel=UILabel(frame: CGRect(x: 0,y: 0, width: self.view.bounds.width, height: self.view.bounds.height))
let emptyLabel2=UILabel(frame: CGRect(x: 0,y: 0, width: self.view.bounds.width, height: self.view.bounds.height))
emptyLabel.text = "no reminder added yet"
emptyLabel.textColor=UIColor.darkGray
emptyLabel.font=UIFont(name: "HelveticaNeue-Light", size: 18)
emptyLabel.textAlignment = NSTextAlignment.center
emptyLabel2.text = "you add by going back to the homescreen"
emptyLabel2.textColor=UIColor.darkGray
emptyLabel2.font=UIFont(name: "HelveticaNeue-Light", size: 12)
emptyLabel2.textAlignment = NSTextAlignment.center
self.tableView.backgroundView = emptyLabel2
self.tableView.separatorStyle = UITableViewCellSeparatorStyle.none
return 0
It works, but how do I add emptyLabel2 beneath the emptyLabel. I want to use the defined label properties.
If you're trying to add your 2 labels to the superview, with emptyLabel2 on top of emptyLabel, all you need to do is this:
self.view.addSubview(emptyLabel)
self.view.addSubview(emptyLabel2)
They will be added in the order you call addSubview.
If you are asking about how to define the frame so that they show one before the next, you need to modify how you are initializing. Something like this (for example):
let emptyLabel=UILabel(frame: CGRect(x: 0,y: 0, width: self.view.bounds.width, height: 20))
let emptyLabel2=UILabel(frame: CGRect(x: 0,y: 20, width: self.view.bounds.width, height: 20))
self.view.addSubview(emptyLabel)
self.view.addSubview(emptyLabel2)
In reality you may want to find a better way to set the size, or just make 1 label with attributedText so that you do not need 2 labels.

I'd like to customize my navigation bar and insert a UIView with two subviews into the title view of the navigation bar.
Unfortunately the subviews aren't displayed.
Do you have any idea why?
let titleContainer = UIView()
titleContainer.frame = CGRect(x: 0, y: 0, width: UIScreen.main.bounds.size.width, height: UIScreen.main.bounds.size.height)
let searchIcon = UIButton()
searchIcon.setImage(UIImage(named: "search_icon"), for: UIControlState.normal)
searchIcon.layer.frame = CGRect(x: 0, y: (UIScreen.main.bounds.size.height - 28) / 2, width: 28, height: 28)
titleContainer.addSubview(searchIcon)
let titleLabel = UILabel()
titleLabel.frame = CGRect(x: 28, y: UIScreen.main.bounds.size.height, width: UIScreen.main.bounds.size.width-28, height: UIScreen.main.bounds.size.height)
titleLabel.textColor = UIColor(red:255, green:255, blue:255, alpha:1.0)
titleContainer.addSubview(self.titleLabel)
self.navigationItem.titleView = titleContainer
problem and expected solution:
Why did you use height of all the element as UIScreen.main.bounds.size.height? Please try the below code.
P.S. I have changed the color of searchIcon as i didn't have the image and changed the color of text of label and added some text so that it is visible.
let titleContainer = UIView()
titleContainer.frame = CGRect(x: 0, y: 0, width: UIScreen.main.bounds.size.width, height: 45)
let searchIcon = UIButton()
//searchIcon.setImage(UIImage(named: "search_icon"), for: UIControlState.normal)
searchIcon.backgroundColor = UIColor.red
searchIcon.layer.frame = CGRect(x: 0, y: 8, width: 28, height: 28)
titleContainer.addSubview(searchIcon)
let titleLabel = UILabel()
titleLabel.frame = CGRect(x: 28, y: 8, width: UIScreen.main.bounds.size.width-28, height: 30)
titleLabel.textColor = UIColor.blue//(red:255, green:255, blue:255, alpha:1.0)
titleContainer.addSubview(titleLabel)
titleLabel.text = "Sample Text"
self.navigationItem.titleView = titleContainer
Here is the screenshot of the above code:
Please change the x,y accordingly as per your requirement.
Have you considered making your let bar = UINavigationBar() programmatically and then add it with: self.view.addSubview(bar)?
So you can push all the "UIBarItems" you want..?
I am trying to create the following registration form . I cant set the space between the textfield image and the placeholder text . I've tried the following :
Email_text.placeholderRect(forBounds: CGRect(x: 10, y: 0 , width: 60, height: 50))
any idea how can I fix this ?
Thanks
You can simply do like this, an extension for UITextField
extension UITextField {
func setTextIconAndPlaceholder(icon: UIImage, placeholder: String) {
let imageView = UIImageView()
imageView.image = icon
imageView.frame = CGRect(x: 0, y: 0, width: 20, height: 20)
let view = UIView()
view.frame = CGRect(x: 0, y: 2, width: 25, height: 25)
view.backgroundColor = UIColor.clear
view.addSubview(imageView)
self.leftView = view
self.leftViewMode = UITextFieldViewMode.always
self.placeholder = placeholder
}
}
For the life of me, I can't figure out how to center a UIButton in UIScrollView...
let sv = UIScrollView(frame: CGRect(x: 0, y: 0, width: 300, height: 600))
let b = UIButton(frame: CGRect(x: 0, y: 0, width: 30, height: 30))
sv.addSubview(b)
b.center = sv.center
No matter what I do, the button seems to be off center. This logic works in normal UIView. Why doesn't it with UIScrollView?
you can also use
let b = UIButton(frame: CGRect(x: sv.frame.size.width/2 -15, y: sv.frame.size.height/2 -15, width: 30, height: 30))
for your code first check value of sv.center, if it is OK and your UI is not updating then call layoutIfneeded
Reference : How is layoutIfNeeded used?
I would like to add a bottom view in all view controllers which will show the progress of Audio or video play.I need Like this
i did in the following
let window = UIApplication.sharedApplication().keyWindow!
let v = UIView(frame: CGRect(x: window.frame.origin.x, y: window.frame.origin.y, width: window.frame.width, height: window.frame.height))
window.addSubview(v);
v.backgroundColor = UIColor.blackColor()
let v2 = UIView(frame: CGRect(x: 50, y: 50, width: 100, height: 50))
v2.backgroundColor = UIColor.whiteColor()
window.addSubview(v2)
But its not displaying in every screen.
I have an approach for you.
Firstly you have to manage this in global way.
You need to create an Object of AppDelegate. And make a function in that class in which you can code
Then on loading your main view, you need to call that function so it will be visible as you want.
How do I add Text and Image on right of the UITextField.
I have a UITextField which will initially have a text/label at right of it and when user click on the button the same textField will now have text + image to the right of UITextField
Image can be added like this but what about the text/label and both ?
txtField.rightViewMode = .always
txtField.rightView = UIImageView(image: UIImage(named: "selectdrop"))
For that you can create on UIView instance and add the UILabel and UIImageView inside it then finally set that view as rightView of textField. Some thing like below.
let rightView = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 40))
let label = UILabel(frame: CGRect(x: 0, y: 0, width: 60, height: 40))
label.text = "Text"
label.textColor = UIColor.red
label.textAlignment = .center
let imageView = UIImageView(frame: CGRect(x: 40, y: 0, width: 40, height: 40))
imageView.image = UIImage(named: "selectdrop")
rightView.addSubview(label)
rightView.addSubview(imageView)
txtField.rightView = rightView
txtField.rightViewMode = .always
