[英]Weird behaviour setting tableView row height and scrollPosition Swift
在同一個viewController
我有一個calendarTableView
代表月份的日期。 在cellForRowAt
我選擇對應於當前日期的行並調用一個函數來填充timeSlotCollectionView
。 這一切都有效,但我有一點奇怪的情況。
情況1:行height
= auto和scrollPosition.none
= timeSlotCollectionView
不遵循cornerRadius
Case2:行height
= auto和scrollPosition.middle
=在calendarTableView
單元格定義上的線程1:EXC_BAD_ACCESS(代碼= 2,地址= 0x659ef4)
Case3:行height
= 44,scrollPosition.none = calendarTableView
單元格不跟隨cornerRadius
情況4:行height
= 44, scrollPosition.middle
= calendarTableView
單元格不跟隨cornerRadius
案例5:行heigh
= 60, scrollPosition.none
= calendarTableView
單元格跟隨cornerRadius
情況6:行height
= 60並且scrollPosition.middle
= calendarTableView
單元格不要再次關注cornerRadius
..
我不介意行高60,但scrollPosition
必須是。中間或我不會看到當天的行..
你能看出我做錯了什么嗎? 我搜索了其他帖子,但我找不到任何能讓我知道問題所在的線索。 非常感謝像往常一樣。 這是calendarTableView
函數:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "calendarCell", for: indexPath) as! CalendarTableViewCell
// Configure the cell...
let date = datesArray[indexPath.row]
print(date)
let calendar = Calendar.current
let components = calendar.dateComponents([.year, .month, .day, .weekday], from: date)
cell.dayLabel.text = "\(String(describing: components.day!))" + " " + "\(dayNamesArray[components.weekday! - 1])"
cell.cellWeekday = components.weekday!
print("cell weekday is: \(cell.cellWeekday!)") // prints correct weekday
cell.cellId = "\(String(format:"%04d", components.year!))" + "\(String(format:"%02d", components.month!))" + "\(String(format:"%02d", components.day!))"
self.selectedDate = cell.cellId // used for time slots cellId
print("##################### selectedDate in tableview is :\(self.selectedDate) ")
// highlighting current day cell
if indexPath.row == self.actualDay - 1 && self.actualMonth == self.displayedMonth {
cell.dayLabel.backgroundColor = UIColor.red.withAlphaComponent(0.3)
// emulate user selecting the cell
tableView.selectRow(at: indexPath, animated: false, scrollPosition: UITableViewScrollPosition.none) // changing to .middle makes the tableview go looping
print(" @@@@@@@@@@@@@@@@@@@@@@@@@@ selected cell weekday is: \(cell.cellWeekday!) @@@@@@@@@@@@@@@@@@@@ ")
// self.updateTimeSlots(selectedCell: cell)
// self.actualWeekday = cell.cellWeekday! // nil error
self.selectedDate = cell.cellId
// calculateOpenTimeSlots()
}
// let cornerRadius: CGFloat = 5
// cell.layer.cornerRadius = cornerRadius
// cell.clipsToBounds = true
// self.updateTimeSlots(selectedCell: cell)
return cell
}
我決定不選擇今天的row
而只是滾動calendarTableView
而不是在那個中間位置。 我還直接在heightForRowAt
聲明row
height
。 calendarTableView
現在按預期運行,並且不直接選擇單元格,而是按照我的實際需要突出顯示。 我希望這會有助於其他人。 最后的功能是:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "calendarCell", for: indexPath) as! CalendarTableViewCell
let cornerRadius: CGFloat = 5
cell.layer.backgroundColor = UIColor.white.cgColor
cell.layer.cornerRadius = cornerRadius
cell.clipsToBounds = true
cell.dayLabel.textColor = UIColor.white
cell.dayLabel.layer.backgroundColor = UIColor.blue.withAlphaComponent(0.3).cgColor
cell.dayLabel.layer.cornerRadius = cornerRadius
cell.dayLabel.clipsToBounds = true
// Configure the cell...
let date = datesArray[indexPath.row]
print(date)
let calendar = Calendar.current
let components = calendar.dateComponents([.year, .month, .day, .weekday], from: date)
cell.dayLabel.text = "\(String(describing: components.day!))" + " " + "\(dayNamesArray[components.weekday! - 1])"
cell.cellWeekday = components.weekday!
print("cell weekday is: \(cell.cellWeekday!)") // prints correct weekday
cell.cellId = "\(String(format:"%04d", components.year!))" + "\(String(format:"%02d", components.month!))" + "\(String(format:"%02d", components.day!))"
self.selectedDate = cell.cellId // used for time slots cellId
print("##################### selectedDate in tableview is :\(self.selectedDate) ")
// highlighting current day cell
if indexPath.row == self.actualDay - 1 && self.actualMonth == self.displayedMonth {
// cell.layer.backgroundColor = UIColor.red.withAlphaComponent(0.3).cgColor
cell.dayLabel.layer.backgroundColor = UIColor.red.withAlphaComponent(0.3).cgColor
// emulate user selecting the cell
// tableView.selectRow(at: indexPath, animated: false, scrollPosition: UITableViewScrollPosition.middle)
tableView.scrollToRow(at: indexPath, at: UITableViewScrollPosition.middle, animated: true)
print(" @@@@@@@@@@@@@@@@@@@@@@@@@@ selected cell weekday is: \(cell.cellWeekday!) @@@@@@@@@@@@@@@@@@@@ ")
self.updateTimeSlots(selectedCell: cell)
// self.actualWeekday = cell.cellWeekday! // nil error
self.selectedDate = cell.cellId
}
return cell
}
