I'm having serious problems getting my multi-line shortcut to display all its lines. Often the last line of the label simply does not appear, but it’s obvious that the dynamically calculated cell height is accepted to take into account that it should have appeared, leaving around a sufficient amount of white space left in my cell.
A damaged label can display 1-7 lines depending on the data. I played with many different restrictions in order to try to display it, but no matter what is on the last line, it just will not be displayed.
Strange, sometimes it will be displayed when I switch to VC, but then when I use the segmented controller inside VC to display different data and then return again, the last line will not be displayed again. The opposite is also common (the last line is the shortcut segments when I switch to VC, but then using the segmented controller inside VC to change the displayed data and then go back, it will be displayed in order).
Things I provided: the label is set to word wrap, has 0 lines, has a height greater than or equal to the height of one of its lines, its resistance and vertical content fit are set to the highest of everything in the cell, and the width is set accordingly.
Below is the code, as I determine how many lines the label will have:
let descString = NSMutableAttributedString()
let bountyStart = NSMutableAttributedString(string: "Bounty: ", attributes: [NSFontAttributeName : UIFont.boldSystemFontOfSize(15)])
let bountyDesc = NSMutableAttributedString(string: bounty.description)
descString.appendAttributedString(bountyStart)
descString.appendAttributedString(bountyDesc)
let bLine = NSMutableAttributedString(string: "\n\n", attributes: [NSFontAttributeName : UIFont.systemFontOfSize(2)])
descString.appendAttributedString(bLine)
if !(bounty.turtles == 0.0){
let turtleStart = NSMutableAttributedString(string: "Your turtle count: ")
let turtleAmount = NSMutableAttributedString(string: bounty.turtleCount.description)
descString.appendAttributedString(turtleStart)
descString.appendAttributedString(turtleAmount)
}
descriptionLabel.attributedText = descString
