当我们请求接口的时候,服务器会返回一些数据,当我们打印的时候就会发现,打印出来的是unicode码,不是汉字。
这时候需要我们自己手动处理一下,让打印的时候输出汉字的格式。
方法如下:
新增一个分类,在分类中,重写描述的方法,如下:
/** * 集合类型打log */ @implementation NSArray (log) - (NSString *)description{ return [self descriptionWithLocale:nil]; } - (NSString *)descriptionWithLocale:(id)locale{ NSMutableString * string = [[NSMutableString alloc]init]; [string appendString:@"[\n"]; for (int i = 0; i < self.count; i++) { [string appendFormat:@"\t第%d个 -- %@ \n",i,self[i] ]; } [string stringByAppendingString:@"]\n"]; return string; } @end @implementation NSDictionary (Log) - (NSString *)jsonDescription { // 参考了此博客 https://www.jianshu.com/p/f14b4cb1435b . // NSString默认使用的是UTF-16,转出UTF-8就能打印了 NSError * error = nil ; NSData *data = [NSJSONSerialization dataWithJSONObject:self options:NSJSONWritingPrettyPrinted error:&error]; if (error) { NSMutableString *strM = [NSMutableString stringWithString:@"{\n"]; [self enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) { [strM appendFormat:@"\t%@ = %@ ;\n", key, obj]; }]; [strM appendString:@"}\n"]; return strM; } NSString *newString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; newString = [newString stringByReplacingOccurrencesOfString:@"\\" withString:@""] ; return newString ; } - (NSString *)description{ return [self descriptionWithLocale:nil]; } - (NSString *)descriptionWithLocale:(id)locale { if ([NSJSONSerialization isValidJSONObject:self]) { return [self jsonDescription]; } // 原来的写法,格式上有点问题,但是转中文是没问题的 NSMutableString *strM = [NSMutableString stringWithString:@"{\n"]; [self enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) { [strM appendFormat:@"\t%@ = %@ ;\n", key, obj]; }]; [strM appendString:@"}\n"]; return strM; } @end
