数组 字典 乱码 json 返回数组 二进制

一、问题描述

1、NSLog显示的数组或者字典乱码
2、输出AFNetWorking返回的json数据，乱码

二、错误展示

三、解决方法

1、数组乱码：重新数组descriptionWithLocale方法，分类实现

#import "NSArray+Log.h"

@implementation NSArray (Log)

- (NSString *)descriptionWithLocale:(id)locale {
    NSMutableString *str = [NSMutableString stringWithFormat:@"%lu (\n", (unsigned long)self.count];
    
    for (id obj in self) {
        [str appendFormat:@"\t%@, \n", obj];
    }
    
    [str appendString:@")"];
    
    return str;
}

@end

2、字典乱码：重新字典descriptionWithLocale方法，分类实现

- (NSString *)descriptionWithLocale:(id)locale {
    NSArray *allKeys = [self allKeys];
    NSMutableString *str = [[NSMutableString alloc] initWithFormat:@"{\t\n "];
    for (NSString *key in allKeys) {
        id value= self[key];
        [str appendFormat:@"\t \"%@\" = %@,\n",key, value];
    }
    [str appendString:@"}"];
    
    return str;
}
