func test(button:UIButton){
var alarm = EKAlarm(relativeOffset: 20)
var event = EKEvent(eventStore: store)
event.title = "xxxx"
event.startDate = NSDate(timeIntervalSinceNow: 20)
event.endDate = NSDate(timeIntervalSinceNow: 1000)
event.calendar = calendarWithName(cal_name)
event.alarms = [alarm]
var ev = EKEventEditViewController()
ev.event = event
ev.eventStore = store
ev.editViewDelegate = self
ev.delegate = self
self.presentViewController(ev, animated: true, completion: nil)
}
func navigationController(navigationController: UINavigationController, willShowViewController viewController: UIViewController, animated: Bool) {
if (viewController.isKindOfClass(UITableViewController.self)){
var tableview = (viewController as UITableViewController).tableView
println(tableview.numberOfSections())
for i in 0...tableview.numberOfSections() {
println(tableview.cellForRowAtIndexPath(NSIndexPath(forRow: 0, inSection: i)) != nil)
}
}
}
我正在使用EKEventEditViewDelegate,willShowViewController功能运行良好,我可以获得正确的表,但我无法获得第5节和下一节,代码有什么问题,我该如何解决这个问题。

文档说cellForRowAtIndexPath(_:)
只返回可见的单元格。
表示表格单元格的对象,如果单元格不是,则为nil visible或indexPath超出范围。
