我试过这个,但它不起作用,文本超出按钮边界.
button.titleLabel!.adjustsFontSizeToFitWidth = true button.titleLabel!.numberOfLines = 0 button.titleLabel!.minimumScaleFactor = 0.1
当我尝试以下操作时,所有文本都适合,但文本仍然是小字体：
button.titleLabel!.font = UIFont(name: "Heiti TC",size: 9)
如何让字体自动适合按钮的大小？
func nextQuestion() {
let currentQuestion = mcArray![questionIdx]
answers = currentQuestion["Answers"] as! [String]
correctAnswer = currentQuestion["CorrectAnswer"] as? String
question = currentQuestion["Question"] as? String
titlesForButtons()
}
func titlesForButtons() {
for (idx,button) in answerButtons.enumerate() {
button.titleLabel!.lineBreakMode = .ByWordWrapping
button.titleLabel!.font = UIFont(name: "Heiti TC",size: 5)
button.titleLabel!.numberOfLines = 0
button.titleLabel!.minimumScaleFactor = 0.1
button.titleLabel!.baselineAdjustment = .AlignCenters
button.titleLabel!.textAlignment = NSTextAlignment.Center
button.setTitle(answers[idx],forState: .Normal)
button.enabled = true
button.backgroundColor = UIColor(red: 83.0/255.0,green: 184.0/255.0,blue: 224.0/255.0,alpha: 1.0)
}
questionLabel.text = question
startTimer()
}
解决方法
你可以试试这个：
1.根据按钮的当前字体大小定义标题大小
let nsTitle = NSString(string:"yourButtonTitle") let font = button.titleLabel?.font let titleSize = nsTitle.sizeWithAttributes([NSFontAttributeName:font])
if titleSize.width > button.titleLabel?.bounds.width{
//set the appropriate font size
}else{
//set the appropriate font size or do nothing
}
