我在我的项目中添加了分段控件来设置通知频率(例如每日、每周、ecc..)。我不明白如何保存用户选择以及如何设置此选择的通知。我有一个 AddController,用户可以在其中插入提醒,在这个 Controller 中我还想设置通知重复的频率。代码是:
@IBAction func salva(sender: UIButton) {
if fieldNomeMedicina.text.isEmpty &&
fieldData.text.isEmpty &&
fieldDosaggio.text.isEmpty{
//alertView che avverte l'utente che tutti i campi sono obbligatori
//return
}
var therapy = PillsModel(nomeMedicinaIn: fieldNomeMedicina.text,
dosaggioIn : fieldDosaggio.text,
dataIn: fieldData.text
)
profilo.therapyArra.append(therapy)
DataManager.sharedInstance.salvaArray()
DataManager.sharedInstance.detail.pillsTable.reloadData()
dismissViewControllerAnimated(true, completion: nil)
let stringDate = fieldData.text//get the time string
//format date
var dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "dd-MM-yyyy hh:mm" //format style. Browse online to get a format that fits your needs.
var date = dateFormatter.dateFromString(stringDate)
//date is your NSdate.
var localNotification = UILocalNotification()
localNotification.category = "FIRST_CATEGORY"
localNotification.fireDate = date
localNotification.alertBody = "Take your medicine:" + " " + fieldNomeMedicina.text + " " + fieldDosaggio.text
localNotification.timeZone = NSTimeZone.defaultTimeZone()
localNotification.applicationIconBadgeNumber = UIApplication.sharedApplication().applicationIconBadgeNumber + 1
UIApplication.sharedApplication().scheduleLocalNotification(localNotification)
}
@IBAction func frequencyControl(sender: UISegmentedControl) {
if(segmentedControl.selectedSegmentIndex == 0)
{
notification.repeatInterval = 0;
}
else if(segmentedControl.selectedSegmentIndex == 1)
{
notification.repeatInterval = .CalendarUnitDay;
}
else if(segmentedControl.selectedSegmentIndex == 2)
{
notification.repeatInterval = .CalendarUnitWeekday;
}
else if(segmentedControl.selectedSegmentIndex == 3)
{
notification.repeatInterval = .CalendarUnitMonth;
}
else if(segmentedControl.selectedSegmentIndex == 4)
{
notification.repeatInterval = .CalendarUnitMinute;
}
}
func drawAShape(notification:NSNotification){
var view:UIView = UIView(frame:CGRectMake(10, 10, 100, 100))
view.backgroundColor = UIColor.redColor()
self.view.addSubview(view)
}
func showAMessage(notification:NSNotification){
var message:UIAlertController = UIAlertController(title: "A Notification Message", message: "Hello there", preferredStyle: UIAlertControllerStyle.Alert)
message.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil))
self.presentViewController(message, animated: true, completion: nil)
}
我遇到错误:在函数频率控制中使用了无法解析的标识符“通知”。
最佳答案
您的问题是,您仅在用户单击按钮后才创建 localNotification
(这是一个很好的设计选择)。这意味着您之前无法在其中存储信息,但这不是必需的 - 您可以随时询问 UISegmentedControl
其当前值是多少。
您基本上需要传输此代码块:
if(segmentedControl.selectedSegmentIndex == 0)
{
notification.repeatInterval = 0;
}
...
在salva
函数内。当您执行此操作时,将 if
语句转换为 switch
- 这样更简洁。它看起来像:
var localNotification = UILocalNotification()
switch segmentedControl.selectedSegmentIndex {
case 0:
localNotification.repeatInterval = 0;
case 1:
localNotification.repeatInterval = .CalendarUnitDay;
...
}
