你可以繼承UITableViewCell
,並添加一個按鈕,下面是一個例子類:
import UIKit
private let DWWatchlistAddSymbolCellAddSymbolButtonLeftMargin: CGFloat = 15
class DWWatchlistAddSymbolCell: UITableViewCell {
private(set) var addSymbolButton:UIButton
init(reuseIdentifier:String?, primaryTextColor:UIColor) {
self.addSymbolButton = UIButton.buttonWithType(UIButtonType.Custom) as! UIButton
super.init(style:UITableViewCellStyle.Default, reuseIdentifier:reuseIdentifier)
selectionStyle = UITableViewCellSelectionStyle.None
backgroundColor = UIColor.clearColor()
imageView!.image = UIImage(named:"PlusIcon")!
addSymbolButton.setTitle("Add Symbol", forState:UIControlState.Normal)
addSymbolButton.setTitleColor(primaryTextColor, forState:UIControlState.Normal)
addSymbolButton.contentHorizontalAlignment = UIControlContentHorizontalAlignment.Left
addSymbolButton.contentVerticalAlignment = UIControlContentVerticalAlignment.Center
contentView.addSubview(addSymbolButton)
}
required init(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
// MARK: Layout
override func layoutSubviews() {
super.layoutSubviews()
addSymbolButton.frame = contentView.frame
let imageViewFrame = imageView!.frame
let imageViewMaxX = imageViewFrame.origin.x + imageViewFrame.size.width
let addSymbolButtonX = imageViewMaxX + DWWatchlistAddSymbolCellAddSymbolButtonLeftMargin
addSymbolButton.contentEdgeInsets = UIEdgeInsetsMake(0, addSymbolButtonX, 0, 0);
}
}
您可以看到 「添加符號」 按鈕,在底部:
當你返回小區的UITableViewDataSource
,確保設定的目標爲按鈕:
private func addButtonCell(tableView: UITableView) -> UITableViewCell {
var cell:DWWatchlistAddSymbolCell? = tableView.dequeueReusableCellWithIdentifier(kDWWatchlistViewControllerAddButtonCellReuseIdentifier) as? DWWatchlistAddSymbolCell
if (cell == nil) {
cell = DWWatchlistAddSymbolCell(reuseIdentifier:kDWWatchlistViewControllerAddButtonCellReuseIdentifier, primaryTextColor:primaryTextColor)
}
cell!.addSymbolButton.addTarget(self,
action:Selector("didPressAddSymbolButton"),
forControlEvents:UIControlEvents.TouchUpInside)
return cell!
}
是你的按鈕是否完全重疊你的手機區域? – saadnib 2011-04-15 09:23:53
沒有它與細胞區域不重疊。它只是右下角單元格的一部分。 – 2011-04-15 09:29:23
