UIAlertcontroller set attributed messages
15,232
You app is crashing because of DataType mismatch.
alert.setValue(<value>, forKey: "attributedMessage")
Here <value>
must be an instance of NSMutableAttributedString
.
But you are passing myAttribute Which is Dictionary
.
It is trying ta call length
method but it is not found on Dictionary
thats why app is crashing.
Try this:
alert.setValue(myString, forKey: "attributedMessage")

How we can set Attributed text in UIAlertcontroller as message. My try code As bellow, but it will crash the app.
// create Attributed text let myAttribute = [NSForegroundColorAttributeName: UIColor(red:122.0/255, green:125.0/255, blue:131.0/255, alpha:1.0),NSFontAttributeName: Constant.flinntRegularFont(15)] let myAttribute2 = [NSForegroundColorAttributeName: UIColor.blackColor(),NSFontAttributeName: Constant.flinntMediumFont(15)] let myString = NSMutableAttributedString(string: "You have been unsubscribed from ", attributes: myAttribute) let myString2 = NSMutableAttributedString(string: self.course.course_name, attributes: myAttribute2) let myString3 = NSMutableAttributedString(string: "\n\nYour refund will be initiated within one week.", attributes: myAttribute) let myString4 = NSMutableAttributedString(string: "\n\nFor any help call us on", attributes: myAttribute) let myString5 = NSMutableAttributedString(string: " 079-4014 9800", attributes: myAttribute2) let myString6 = NSMutableAttributedString(string: " between 9:30 am to 6:30 pm on Monday to Saturday.\n\nWe will be always here with great deals to share.", attributes: myAttribute) myString.appendAttributedString(myString2) myString.appendAttributedString(myString3) myString.appendAttributedString(myString4) myString.appendAttributedString(myString5) myString.appendAttributedString(myString6)
Present UIAlertcontroller Code
let alert = UIAlertController(title: "", message: "Select course", preferredStyle: UIAlertControllerStyle.Alert) alert.setValue(myAttribute, forKey: "attributedMessage") // this line make a crash. alert.addAction(UIAlertAction(title: "OK", style: .Cancel, handler: { (action) in self.delegate?.courseRefundViewControllerCoursrRefunded?(self) self.navigationController?.popViewControllerAnimated(true) })) self.presentViewController(alert, animated: true, completion: nil)
Thanks.
