设置 UIAlertViewController的字体

我们总会遇到使用UIAlertViewController

由于默认在一行显示,如果每行字数不一样造成字体大小每行不一致,展示上是很难看的

这时需要设置字体的一些方法

 func setAlert(){

 personAlert = UIAlertController.init(title: nil, message: nil, preferredStyle: .actionSheet)

 let apperanceLabel = UILabel.appearance(whenContainedInInstancesOf: [UIAlertController.self])

 apperanceLabel.numberOfLines = 0

 for val in UserInfo.rightGroupId{

 let setAct = UIAlertAction.init(title: val.organizationName + "-" + val.roleName, style: .default, handler: { (a) in

 print(val.roleId,val.organizationId)

 UserInfo.currentRoleId = val.roleId

 UserInfo.currentOrganizationId = val.organizationId

 UserInfo.userSave()

 DispatchQueue.main.async {

 let control = MainStoryboard.instantiateViewController(withIdentifier: "TabViewController") as! TabViewController

 control.selectedIndex = 0

 UIApplication.shared.delegate?.window??.rootViewController = control

 UIApplication.shared.statusBarStyle = .default

 }

 })

 setAct.setValue(UIColor.init(red: 51.0/255.0, green: 51.0/255.0, blue: 51.0/255.0, alpha: 1), forKey: "_titleTextColor")

 personAlert.addAction(setAct)

 }

 let cancalAct = UIAlertAction.init(title: "取消", style: .cancel, handler: { (a) in

 })

 cancalAct.setValue(UIColor.init(red: 51.0/255.0, green: 51.0/255.0, blue: 51.0/255.0, alpha: 1), forKey: "_titleTextColor")

 personAlert.addAction(cancalAct)

 }
