Label not display in subview of UITableView - ios

Question

I am designing an iOS hamburger menu with a table view in swift3
I want to display the number of notifications in menu tab.
let pieNotifi = UIImageView(frame: CGRectMake(cell.contentView.frame.size.width-40, cell.contentView.frame.size.height/2-7, 30, 20))
let pieLabNotifi = UILabel(frame: CGRectMake(cell.contentView.frame.size.width-40, cell.contentView.frame.size.height/2-7, 30, 20))
let subviews = self.view.viewWithTag(100001)
if myGlobal.unreaddot != 0 { //just a count for notifcaiton
if subviews == nil {
pieNotifi.tag = 100001;
cell.addSubview(pieNotifi)
let pieShape = pieNotifi.layer;
pieShape.backgroundColor = UIColor.red.cgColor
pieShape.cornerRadius = pieShape.bounds.width / 4
pieLabNotifi.textColor = UIColor.white
pieLabNotifi.adjustsFontSizeToFitWidth = true;
pieLabNotifi.minimumScaleFactor = 0.5
pieLabNotifi.textAlignment = NSTextAlignment.center
pieNotifi.addSubview(pieLabNotifi)
pieLabNotifi.text = String(myGlobal.unreaddot)
}
else{
pieLabNotifi.text = String(myGlobal.unreaddot)
}
}else{
let subviews = cell.viewWithTag(100001)
subviews?.removeFromSuperview()
print("remove red dot")
}
however, it only display the red colour layer but do not have the label. refer to the picture shown below
enter image description here
I had tried to set
.sendSubview(to back:)
.bringSubview(toFront: )
.layer.zPosition = 1
all these key word not work for me.
Can anyone advise me to solve this problem?

Answer 1

You are not adding subview to UITableView. According to your code you are adding a subview to the cell of UITableView.
Try to add the subview to the content view of the cell, like:
cell.contentView.addSubView(pieNotifi)

Answer 2

i think the issue is with the positions of your label. You are giving your label x coordinate as cell.contentView.frame.size.width-40, but you want to add it inside the red image view. Changing the x position and y position to 0 (or whatever value you need )for your label will solve your problem. I have modified your code accordingly :
let pieNotifi = UIImageView(frame: CGRectMake(cell.contentView.frame.size.width-40, cell.contentView.frame.size.height/2-7, 30, 20))
let pieLabNotifi = UILabel(frame: CGRectMake(0,0, 30, 20))
let subviews = self.view.viewWithTag(100001)
if myGlobal.unreaddot != 0 { //just a count for notifcaiton
if subviews == nil {
pieNotifi.tag = 100001;
cell.addSubview(pieNotifi)
let pieShape = pieNotifi.layer;
pieShape.backgroundColor = UIColor.red.cgColor
pieShape.cornerRadius = pieShape.bounds.width / 4
pieLabNotifi.textColor = UIColor.white
pieLabNotifi.adjustsFontSizeToFitWidth = true;
pieLabNotifi.minimumScaleFactor = 0.5
pieLabNotifi.textAlignment = NSTextAlignment.center
pieNotifi.addSubview(pieLabNotifi)
pieLabNotifi.text = String(myGlobal.unreaddot)
}
else{
pieLabNotifi.text = String(myGlobal.unreaddot)
}
}else{
let subviews = cell.viewWithTag(100001)
subviews?.removeFromSuperview()
print("remove red dot")
}
Also try to see your label position in UiDebugger , you might discover that label is added at wrong position.
