所以我已經到處檢查,似乎無法找到我正在尋找的答案。這是我的問題:我有一個UITableView與其中的不同部分。每個部分都有一個標題,當點擊時,它會展開該部分並顯示它的行或單元格。但是,當您點擊標題時,它會展開它的部分,但它保持在它的位置。點擊時,我希望該部分標題移動到頂部。以下是示例代碼。我希望我解釋得很好。Swift 2.0 UITableView Section Header點擊滾動到頂部
這裏是節頭本身:
func configureHeader(view: UIView, section: Int) {
view.backgroundColor = UIColor.whiteColor()
view.tag = section
let headerString = UILabel(frame: CGRect(x: 40, y: 15, width: tableView.frame.size.width-10, height: 40)) as UILabel
headerString.text = sectionTitleArray.objectAtIndex(section) as? String
headerString.textAlignment = .Left
headerString.font = UIFont.systemFontOfSize(24.0)
view .addSubview(headerString)
let frame = CGRectMake(5, view.frame.size.height/2, 20, 20)
let headerPicView = UIImageView(frame: frame)
headerPicView.image = headerPic
view.addSubview(headerPicView)
let headerTapped = UITapGestureRecognizer (target: self, action:"sectionHeaderTapped:")
view .addGestureRecognizer(headerTapped)
}
這裏是sectionHeaderTapped功能:
func sectionHeaderTapped(recognizer: UITapGestureRecognizer) {
print("Tapping working")
print(recognizer.view?.tag)
let indexPath : NSIndexPath = NSIndexPath(forRow: 0, inSection:(recognizer.view?.tag as Int!)!)
if (indexPath.row == 0) {
var collapsed = arrayForBool .objectAtIndex(indexPath.section).boolValue
collapsed = !collapsed;
arrayForBool .replaceObjectAtIndex(indexPath.section, withObject: collapsed)
//reload specific section animated
let range = NSMakeRange(indexPath.section, 1)
let sectionToReload = NSIndexSet(indexesInRange: range)
self.tableView .reloadSections(sectionToReload, withRowAnimation:UITableViewRowAnimation.Fade)
}
}
謝謝!
工作完美!我做了'self.tableView.scrollToRowAtIndexPath(indexPath,atScrollPosition:.Top,animated:true)',並把它放在sectionHeaderTapped函數中。謝謝!! –
完成了很好的工作,謝謝 – Gaurav
