I renamed a file. No errors appeared in my code but yet received this message. Help please! Error given (not sure why stack asks me for more info, but I have tried all things to resolve the issue eg, DerivedData, making a new playgrounds, ect) (I can't input my whole code here unfortunately, would really appreciate the help because I'm still relatively new to Swift and I don't even know what's EXC_BREAKPROINT(code=1) error is about despite googling for solutions.)

There can be two approach to this:
rebuild all of your line
shortcut to cleaning is this one:
shift+command+K
as you said you renamed the file.other thing you can do is copy past all code into new file with your requried name.
this should work if your code is good else please do share the code.
how can i get UIlabel to get in the middle of the container? and that text and view disappear equally and come to the next view.
EDIT: This code is working fine for me now
class TestViewController: UIViewController {
let container = UIView()
let redSquare = UIView()
let blueSquare = UIView()
let label = UILabel()
override func viewDidLoad() {
super.viewDidLoad()
self.label.textColor = UIColor.orange
self.label.font = label.font.withSize(25)
self.label.numberOfLines = 0
self.label.center = self.blueSquare.center
self.label.textAlignment = NSTextAlignment.center
self.label.text =
"sosdihfiosdfhsdhfdisfhsdfhdsoifhsdofhsdifhdsofhdsofhsdohdsfdosdohdfh"
self.blueSquare.addSubview(label)
self.label.frame = CGRect(x: 45, y: 120, width: 300, height: 100)
self.container.frame = CGRect(x: 7, y: 200, width: 400, height: 500)
self.view.addSubview(container)
self.redSquare.frame = CGRect(x: 0, y: 0, width: 400, height: 500)
self.blueSquare.frame = redSquare.frame
self.redSquare.backgroundColor = UIColor.darkGray
self.blueSquare.backgroundColor = UIColor.darkGray
self.container.addSubview(self.redSquare)
}
Define two labels like:
let label = UILabel(frame: CGRect(x: 0, y: 0, width: 200, height: 30))
let label2 = UILabel(frame: CGRect(x: 0, y: 0, width: 200, height: 30))
then inside viewDidLoad() before adding redSquare to container fix some labels's property and add label's to blue and red square:
label.center = self.redSquare.center
label.textAlignment = NSTextAlignment.center
label.text = "same text"
label2.textAlignment = NSTextAlignment.center
label2.center = self.blueSquare.center
label2.text = "same text"
self.blueSquare.addSubview(label2)
self.redSquare.addSubview(label)
I try to add a UIStackView as a custom view of a UIBarButtonItem.
I first tried adding a UIView as the custom view.
let list = UIView(frame: CGRect(x: 0, y: 0, width: 250, height: 44))
list.backgroundColor = .green
list.addSubview(stackView)
let item = UIBarButtonItem(customView: list )
topViewController?.setToolbarItems([item], animated: true)
This works. I get a green bar in the UIToolBar. Then I tried adding a UIStackView to the UIView.
let red = UIView(frame: CGRect(x: 0, y: 0, width: 250, height: 30))
red.backgroundColor = .red
let stackView = UIStackView(frame: CGRect(origin: CGPoint.zero,
size: CGSize(width: 250, height: 44)))
stackView.distribution = .fillEqually
stackView.axis = .horizontal
stackView.spacing = 5
stackView.alignment = .center
stackView.translatesAutoresizingMaskIntoConstraints = false
stackView.addArrangedSubview(red)
let list = UIView(frame: CGRect(x: 0, y: 0, width: 250, height: 44))
list.backgroundColor = .green
list.addSubview(stackView)
let item = UIBarButtonItem(customView: list )
topViewController?.setToolbarItems([item], animated: true)
However, when I try this, nothing happens. The UIToolBar seems empty. What am I doing wrong?
In this answer, I have used two UIViews.
You have to give height constraints for two UIViews
red.heightAnchor.constraint(equalToConstant: 30).isActive = true;
green.heightAnchor.constraint(equalToConstant: 30).isActive = true;
You have to comment this line,
//stackView.translatesAutoresizingMaskIntoConstraints = false
Full Code:
self.navigationController?.isToolbarHidden = false
let red = UIView(frame: CGRect(x: 0, y: 0, width: 10, height: 30))
red.backgroundColor = .red
let green = UIView(frame: CGRect(x: 0, y: 0, width: 10, height: 30))
green.backgroundColor = .green
red.heightAnchor.constraint(equalToConstant: 30).isActive = true;
green.heightAnchor.constraint(equalToConstant: 30).isActive = true;
let stackView = UIStackView(frame: CGRect(x: 0, y: 0, width: 250, height: 30))
stackView.distribution = .fillEqually
stackView.axis = .horizontal
stackView.spacing = 5
stackView.alignment = .center
//stackView.translatesAutoresizingMaskIntoConstraints = false
stackView.addArrangedSubview(red)
stackView.addArrangedSubview(green)
let list = UIView(frame: CGRect(x: 0, y: 0, width: 250, height: 44))
list.backgroundColor = .yellow
list.addSubview(stackView)
let item = UIBarButtonItem(customView: list )
self.setToolbarItems([item], animated: true)
Output:
I am currently using the following code to display a datepicker when a user clicks on a UITextfield. This works fine, but the problem is there left and right button are not properly vertically center aligned. Is there any way to accomplish this? I tried using UIOffset on the buttons but without result.

width: self.view.frame.size.width, height: 40.0))
toolBar.layer.position = CGPoint(x: self.view.frame.size.width/2, y: self.view.frame.size.height-20.0)
toolBar.barStyle = UIBarStyle.blackTranslucent
toolBar.tintColor = UIColor.white
toolBar.backgroundColor = UIColor.black
let cancelBtn = UIBarButtonItem(title: "cancel".localized(lang: Localize.currentLanguage()), style: UIBarButtonItemStyle.plain, target: self,
action: #selector(tapppedToolBarBtn))
let okBarBtn = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.done, target: self,
action: #selector(donePressed))
let flexSpace = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.flexibleSpace,
target: self, action: nil)
let label = UILabel(frame: CGRect(x: 0, y: 0, width: self.view.frame.size.width / 3,
height: self.view.frame.size.height))
label.font = UIFont(name: "Roboto-Regular", size: 12)
label.backgroundColor = UIColor.clear
label.textColor = UIColor.white
label.text = "selectdate".localized(lang: Localize.currentLanguage())
label.textAlignment = NSTextAlignment.center
let textBtn = UIBarButtonItem(customView: label)
toolBar.setItems([cancelBtn, flexSpace, textBtn, flexSpace, okBarBtn], animated: true)
startDateTxf.inputAccessoryView = toolBar
}
The result :
Result of the datepicker toolbar
I managed to fix this alignment issue by using the following code :
let toolBar = UIToolbar(frame: CGRect(x: 0, y: self.view.frame.size.height/6,
width: self.view.frame.size.width, height: 40.0))
toolBar.layer.position = CGPoint(x: self.view.frame.size.width/2, y: self.view.frame.size.height-20.0)
toolBar.barStyle = UIBarStyle.blackTranslucent
toolBar.tintColor = UIColor.white
toolBar.backgroundColor = UIColor.black
let cancelBtn1 = UIButton(frame: CGRect(x: 0, y: 0, width: self.view.frame.size.width / 4,
height: self.view.frame.size.height))
cancelBtn1.setTitle("cancel".localized(lang: Localize.currentLanguage()), for: .normal)
cancelBtn1.addTarget(self, action: #selector(tapppedToolBarBtn), for: .touchUpInside)
let cancelBtn = UIBarButtonItem(customView: cancelBtn1)
let okBarBtn1 = UIButton(frame: CGRect(x: 0, y: 0, width: self.view.frame.size.width / 4,
height: self.view.frame.size.height))
okBarBtn1.setTitle("Done", for: .normal)
okBarBtn1.addTarget(self, action: #selector(donePressed(sender:)), for: .touchUpInside)
let okBarBtn = UIBarButtonItem(customView: okBarBtn1)
let flexSpace = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.flexibleSpace,
target: self, action: nil)
let label = UILabel(frame: CGRect(x: 0, y: 0, width: self.view.frame.size.width / 3,
height: self.view.frame.size.height))
label.font = UIFont(name: "Roboto-Regular", size: 12)
label.backgroundColor = UIColor.clear
label.textColor = UIColor.white
label.text = "selectdate".localized(lang: Localize.currentLanguage())
label.textAlignment = NSTextAlignment.center
let textBtn = UIBarButtonItem(customView: label)
toolBar.setItems([cancelBtn, flexSpace, textBtn, flexSpace, okBarBtn], animated: true)
startDateTxf.inputAccessoryView = toolBar
The result is : result in simulator
I'm trying to make a contour of two UIViews but by using the border property I can't seem to achieve what I want. I'm getting the image on the left, and I want the one on the right:
Here's my code:
let main = UIView()
main.frame = CGRect(x: 50, y: 50, width: 200, height: 100)
main.backgroundColor = UIColor.clear
self.view.addSubview(main)
let v1 = UIView()
v1.frame = CGRect(x: 0, y: 0, width: 200, height: 50)
v1.backgroundColor = UIColor.blue
main.addSubview(v1)
let v2 = UIView()
v2.frame = CGRect(x: 0, y: 50, width: 150, height: 50)
v2.backgroundColor = UIColor.red
main.addSubview(v2)
main.clipsToBounds = true
main.layer.borderColor = UIColor.black.cgColor
main.layer.borderWidth = 3
You need to create custom shaped border layer like so:
let main = UIView()
main.frame = CGRect(x: 50, y: 50, width: 200, height: 100)
main.backgroundColor = UIColor.clear
self.view.addSubview(main)
let v1 = UIView()
v1.frame = CGRect(x: 0, y: 0, width: 200, height: 50)
v1.backgroundColor = UIColor.blue
main.addSubview(v1)
let v2 = UIView()
v2.frame = CGRect(x: 0, y: 50, width: 150, height: 50)
v2.backgroundColor = UIColor.red
main.addSubview(v2)
// Custom Shape Layer
let maskLayer = CAShapeLayer()
maskLayer.frame = main.bounds
// Custom CGPath
let resultPath = CGMutablePath()
resultPath.addPath(CGPath(rect: v1.frame, transform: nil))
resultPath.addPath(CGPath(rect: v2.frame, transform: nil))
maskLayer.path = resultPath
// Add border
let borderLayer = CAShapeLayer()
borderLayer.path = maskLayer.path
borderLayer.strokeColor = UIColor.black.cgColor
borderLayer.lineWidth = 5
borderLayer.frame = main.bounds
borderLayer.zPosition = -1
main.layer.addSublayer(borderLayer)
