将文本标签设置为时间间隔的差异
Setting text labels to the difference in time intervals
我正在尝试为两个对象之间的时间差设置一个文本标签;当前时间和 Parse 中保存的时间。我的问题是最后的 if/else 语句。标签都分配有 datesHours 或 datesMinutes 字典,而 datesHours 字典应仅在小时大于 1 时分配 - 否则,文本标签应显示分钟数。
我做错了什么?
var datesHours = [Int: String]()
var datesMinutes = [Int: String]()
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("MyCell") as! TableViewCell
var query = PFQuery(className: "Items")
query.findObjectsInBackgroundWithBlock { (objects: [AnyObject]?, error: NSError?) -> Void in
if error == nil {
if let objects = objects {
for (index, title) in enumerate(objects) {
let itemDate = (title as! PFObject)["date"] as! NSDate
var timeDifference = NSDate().timeIntervalSinceDate(itemDate)
var time = Int(timeDifference)
var minutes = ((time / 60) % 60)
var hours = (time / 3600)
self.datesHours[index] = String(hours)
self.datesMinutes[index] = String(minutes)
//println(self.datesMinutes)
//println(self.datesHours)
for (index, hour) in self.datesHours {
if hour == "\(0)" {
cell.timeLabel.text = self.datesMinutes[indexPath.row]! + "m"
} else {
cell.timeLabel.text = self.datesHours[indexPath.row]! + "hr"
}
}
}
}
}
}
如果您的数据是正确的,并且您有一组字典需要显示在您的单元格上。试试这个:
cell.textLabel.text = [[mArray objectAtIndex:indexPath.row] objectForKey:@"HOUR OR MINUTE KEY"];
