NSDictionary打印编码改中文的方法

1，转NSData

NSData *jsonData = [NSJSONSerialization dataWithJSONObject:json options:NSJSONWritingPrettyPrinted error:nil];

NSString *jsonStr = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

NSLog(@"这是全部数据%@",jsonStr);

2，为NSDictionary加分类方法

- (NSString*)my_description {

NSString *desc = [self description];

desc = [NSString stringWithCString:[desc cStringUsingEncoding:NSUTF8StringEncoding] encoding:NSNonLossyASCIIStringEncoding];

return desc;

}

改系统方法，有一定风险

3，lldb(待定)
