详细内容

1. Swift 使用示例

1. 示例一

   self.allList.sortUsingComparator(
            {
                (s1:AnyObject!,s2:AnyObject!)->NSComparisonResult in
                var obj1=s1 as CareerCheck
                var obj2=s2 as CareerCheck
                if obj1.cItemUpdateTime < obj2.cItemUpdateTime{
                    return NSComparisonResult.OrderedAscending
                }else{
                    return NSComparisonResult.OrderedDescending
                }
        })
   

2. 示例二

   self.auctionList.sortUsingComparator({
   
    (s1:AnyObject!,s2:AnyObject!)->NSComparisonResult in
   
    var obj1 = s1 as Auction
    var obj2 = s2 as Auction
   
    if aKey == "Name"
    {
        return obj1.aName.compare(obj2.aName, options: NSStringCompareOptions.NumericSearch | NSStringCompareOptions.CaseInsensitiveSearch, range: nil, locale: nil)
    }
    else if aKey == "Time Left"
    {
        return obj1.aEndTime.compare(obj2.aEndTime, options: NSStringCompareOptions.NumericSearch, range: nil, locale: nil)
    }
    else if aKey == "Lowest Bid"
    {
        return obj1.aLowestBid.compare(obj2.aLowestBid, options: NSStringCompareOptions.NumericSearch, range: nil, locale: nil)
    }
    else if aKey == "My Bid"
    {
        return obj1.aMyBid.compare(obj2.aMyBid, options: NSStringCompareOptions.NumericSearch, range: nil, locale: nil)
    }
    else
    {
        return obj1.aMyRank.compare(obj2.aMyRank, options: NSStringCompareOptions.NumericSearch, range: nil, locale: nil)
    }
   })
   

2. Objective-C 使用示例

arryA =  [arryB sortedArrayUsingComparator: ^(id obj1, id obj2) {
        if ([[obj1 index3] integerValue]> [[obj2 index3] integerValue]) {
            return (NSComparisonResult)NSOrderedDescending;
        }
        if ([[obj1 index3] integerValue]< [[obj2 index3] integerValue]) {
            return (NSComparisonResult)NSOrderedAscending;
        }
        return (NSComparisonResult)NSOrderedSame;
    }];

3. 函数使用说明

func compare(aString: String, options mask: NSStringCompareOptions = default, range: Range<String.Index>? = default, locale: NSLocale? = default) -> NSComparisonResult

这是 Cocoa 在 Swift 中所添加的扩展之一，用于比较两个字符串

其中 NSStringCompareOptions 参数用于设置比较规则

Range 参数用于设置比较范围

NSlocale 参数用于提供于用户所处地域相关的定制化信息和首选项信息的设置
