如题,网上找了都是比较旧的 关于 NSPropertyListSerialization的,可是这个类库github上都找不着下载啊...
温故而知新,可以为师矣。 博客:www.ouyangke.com
API都写的很 清楚了 Use propertyListWithData:options:format:error: instead.[NSPropertyListSerialization propertyListWithData:tempData options:NSPropertyListImmutable format:NULL error:NULL];
[NSPropertyListSerialization propertyListWithData:tempData options:NSPropertyListImmutable format:NULL error:NULL];
系统库不能解决问题?
测试代码:
NSString *dataStr = @"求助~ Unicode 转 NSString"; NSString *utf8Str = [NSString replaceUnicode:dataStr]; NSLog(@" utf8Str = %@",utf8Str); NSString *unnicodeStr = [NSString utf8ToUnicode:utf8Str]; NSLog(@" unicode = %@",unnicodeStr);
运行结果:把这两个方法写到NSString分类中
//Unicode转UTF-8 + (NSString*) replaceUnicode:(NSString*)aUnicodeString { NSString *tempStr1 = [aUnicodeString stringByReplacingOccurrencesOfString:@"\u" withString:@"\U"]; NSString *tempStr2 = [tempStr1 stringByReplacingOccurrencesOfString:@"\"" withString:@"\\""]; NSString *tempStr3 = [[@"\"" stringByAppendingString:tempStr2] stringByAppendingString:@"\""]; NSData *tempData = [tempStr3 dataUsingEncoding:NSUTF8StringEncoding]; NSString* returnStr = [NSPropertyListSerialization propertyListFromData:tempData mutabilityOption:NSPropertyListImmutable format:NULL errorDescription:NULL]; return [returnStr stringByReplacingOccurrencesOfString:@"\r\n" withString:@"\n"]; } // utf8转unnicode +(NSString *) utf8ToUnicode:(NSString *)string { NSUInteger length = [string length]; NSMutableString *str = [NSMutableString stringWithCapacity:0]; for (int i = 0;i < length; i++) { unichar _char = [string characterAtIndex:i]; //判断是否为英文和数字 if (_char <= '9' && _char >= '0') { [str appendFormat:@"%@",[string substringWithRange:NSMakeRange(i, 1)]]; } else if(_char >= 'a' && _char <= 'z') { [str appendFormat:@"%@",[string substringWithRange:NSMakeRange(i, 1)]]; } else if(_char >= 'A' && _char <= 'Z') { [str appendFormat:@"%@",[string substringWithRange:NSMakeRange(i, 1)]]; } else { [str appendFormat:@"\u%x",[string characterAtIndex:i]]; } } return str; }
