原文：http://lovebirdegg.co.tv/2010/04/how-to-reverse-a-nsstring/
some time you want to recerse a nsstring

for example：

"你好"to"好你"


i Searched the api but have no result，the method above can solute it

NSString *content = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];



int len = [content length];

// Auto released string



NSString * reversedStr = [[NSMutableString alloc] init];



// Probably woefully inefficient...

while (len > 0)

[reversedStr appendString:

[NSString stringWithFormat:@"%C", [content characterAtIndex:--len]]];

NSLog(reversedStr);
