我一直在尝试向我的应用程序添加相同的功能，在经历了许多不同的教程（raywenderlich是最好的DIY解决方案）之后，我发现Apple拥有自己的UITableViewRowAction类，非常方便。
您必须将Tableview的锅炉方法更改为此：
override func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? {
// 1
var shareAction = UITableViewRowAction(style: UITableViewRowActionStyle.Default, title: "Share" , handler: { (action:UITableViewRowAction!, indexPath:NSIndexPath!) -> Void in
// 2
let shareMenu = UIAlertController(title: nil, message: "Share using", preferredStyle: .ActionSheet)
let twitterAction = UIAlertAction(title: "Twitter", style: UIAlertActionStyle.Default, handler: nil)
let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel, handler: nil)
shareMenu.addAction(twitterAction)
shareMenu.addAction(cancelAction)
self.presentViewController(shareMenu, animated: true, completion: nil)
})
// 3
var rateAction = UITableViewRowAction(style: UITableViewRowActionStyle.Default, title: "Rate" , handler: { (action:UITableViewRowAction!, indexPath:NSIndexPath!) -> Void in
// 4
let rateMenu = UIAlertController(title: nil, message: "Rate this App", preferredStyle: .ActionSheet)
let appRateAction = UIAlertAction(title: "Rate", style: UIAlertActionStyle.Default, handler: nil)
let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel, handler: nil)
rateMenu.addAction(appRateAction)
rateMenu.addAction(cancelAction)
self.presentViewController(rateMenu, animated: true, completion: nil)
})
// 5
return [shareAction,rateAction]
}
您可以在本网站上找到更多有关此的信息。Apple 自己的文档对于更改背景颜色非常有用：
操作按钮的背景色。
声明OBJECTIVE-C @property（非原子，复制）UIColor * backgroundColor讨论使用此属性可以指定按钮的背景色。如果未为此属性指定值，则UIKit将基于style属性中的值分配默认颜色。
可用性在iOS 8.0和更高版本中可用。
如果要更改按钮的字体，则比较棘手。我看过另一篇关于SO的文章。为了提供代码和链接，下面是他们在此处使用的代码。您必须更改按钮的外观。您必须对tableviewcell进行特定的引用，否则您将在整个应用程序中更改按钮的外观（我不希望那样，但是您可能不知道:)）
目标C：
+ (void)setupDeleteRowActionStyleForUserCell {
UIFont *font = [UIFont fontWithName:@"AvenirNext-Regular" size:19];
NSDictionary *attributes = @{NSFontAttributeName: font,
NSForegroundColorAttributeName: [UIColor whiteColor]};
NSAttributedString *attributedTitle = [[NSAttributedString alloc] initWithString: @"DELETE"
attributes: attributes];
/*
* We include UIView in the containment hierarchy because there is another button in UserCell that is a direct descendant of UserCell that we don't want this to affect.
*/
[[UIButton appearanceWhenContainedIn:[UIView class], [UserCell class], nil] setAttributedTitle: attributedTitle
forState: UIControlStateNormal];
}
迅速：
//create your attributes however you want to
let attributes = [NSFontAttributeName: UIFont.systemFontOfSize(UIFont.systemFontSize())] as Dictionary!
//Add more view controller types in the []
UIButton.appearanceWhenContainedInInstancesOfClasses([ViewController.self])
这是最简单，最简化的版本恕我直言。希望能帮助到你。
更新：这是Swift 3.0版本：
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
var shareAction:UITableViewRowAction = UITableViewRowAction(style: .default, title: "Share", handler: {(action, cellIndexpath) -> Void in
let shareMenu = UIAlertController(title: nil, message: "Share using", preferredStyle: .actionSheet)
let twitterAction = UIAlertAction(title: "Twitter", style: .default, handler: nil)
let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
shareMenu.addAction(twitterAction)
shareMenu.addAction(cancelAction)
self.present(shareMenu,animated: true, completion: nil)
})
var rateAction:UITableViewRowAction = UITableViewRowAction(style: .default, title: "Rate" , handler: {(action, cellIndexpath) -> Void in
// 4
let rateMenu = UIAlertController(title: nil, message: "Rate this App", preferredStyle: .actionSheet)
let appRateAction = UIAlertAction(title: "Rate", style: .default, handler: nil)
let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
rateMenu.addAction(appRateAction)
rateMenu.addAction(cancelAction)
self.present(rateMenu, animated: true, completion: nil)
})
// 5
return [shareAction,rateAction]
}
