Javascript与Objective-C 字符串与数组的方法类比

String vs NSString

JavaScript string	Obj-C NSString
charAt(index)	(see text)
charCodeAt(index)	- (unichar)characterAtIndex:(NSUInteger)index
concat(string)	- (NSString *)stringByAppendingString:(NSString *)aString
indexOf(string)	- (NSRange)rangeOfString:(NSString *)aString
lastIndexOf(string)	- (NSRange)rangeOfString:(NSString *)aString options:NSBackwardsSearch
localeCompare(string)	- (NSComparisonResult)localizedCompare:(NSString *)aString
split(delimiter)	- (NSArray *)componentsSeparatedByString:(NSString *)separator
substring(startIndex)	- (NSString *)substringWithRange:(NSRange)aRange
toLowerCase()	- (NSString *)lowercaseString
toUpperCase()	- (NSString *)uppercaseString

 

Array vs NSArray

JavaScript Array	Obj-C NSArray
length	- (NSUInteger)count
concat(item1[, item2...])	- (NSArray *)arrayByAddingObject:(id)anObject -(NSArray *)arrayByAddingObjectsFromArray:(NSArray *)otherArray
join(delimiter)	- (NSString *)componentsJoinedByString:(NSString *)separator
sort()	- (NSArray *)sortedArrayUsingFunction:(NSInteger (*)(id, id, void *))comparator context:(void *)context
