NSLog 日志打印出中文

1 - NSLog日志可以正常打印出中文，而不被编译成其它字符，对字典进行扩展即可

2 - 代码示例

// - NSDictionary+Log.m

 1 #import "NSDictionary+Log.h"
 2 @implementation NSDictionary (Log)
 3 - (NSString *)descriptionWithLocale:(id)locale {
 4     
 5     NSMutableString *string = [NSMutableString string];
 6     
 7     // 开头有个{
 8     [string appendString:@"{\n"];
 9     
10     // 遍历所有的键值对
11     [self enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
12         [string appendFormat:@"\t%@", key];
13         [string appendString:@" : "];
14         [string appendFormat:@"%@,\n", obj];
15     }];
16     
17     // 结尾有个}
18     [string appendString:@"}"];
19     
20     // 查找最后一个逗号
21     NSRange range = [string rangeOfString:@"," options:NSBackwardsSearch];
22     if (range.location != NSNotFound)
23         [string deleteCharactersInRange:range];
24     
25     return string;
26 }
27 @end
