iOS Unicode转中文(UTF-8)

unicode转汉字例如服务器给我们的原始字符串为

\\u6b63\\u5728\\u52a0\\u70ed\\uff0c\\u5f53\\u524d\\u6e29\\u5ea6\\uff1a30.0\\u2103需要转为中文该怎么办呢？\号后面加个字符就会被转译成其他字符，烦躁，冷静下还是老实写吧，参考了圈，这个方法最好用

- (NSString*) replaceUnicode:(NSString*)TransformUnicodeString{
NSString*tepStr1 = [TransformUnicodeString stringByReplacingOccurrencesOfString:@"\\u"withString:@"\\U"];
NSString*tepStr2 = [tepStr1 stringByReplacingOccurrencesOfString:@"\""withString:@"\\\""];
NSString*tepStr3 = [[@"\""  stringByAppendingString:tepStr2]stringByAppendingString:@"\""];
NSData*tepData = [tepStr3  dataUsingEncoding:NSUTF8StringEncoding];
NSString*axiba = [NSPropertyListSerialization    propertyListWithData:tepDataoptions:NSPropertyListMutableContainersformat:NULLerror:NULL];
return  [axiba    stringByReplacingOccurrencesOfString:@"\\r\\n"withString:@"\n"];
}
