在iOS开发中，经常需要查看数组中得元素是否是自己想要的，但是苹果并没有对直接打印数组中得中文作处理，直接打印就会出现一堆很讨厌的东西，解决其实很简单，就是需要通过为NSArray添加分类，重写 - (NSString *)descriptionWithLocale:(id)locale方法即可
代码如下：
#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
同理要解决NSDictionary乱码问题，也需要为NSDictionary类添加一个分类，重写 - (NSString *)descriptionWithLocale:(id)locale方法
代码如下：
1 #import "NSDictionary+MyLog.h"
2
3 @implementation NSDictionary (MyLog)
4
5
6 - (NSString *)descriptionWithLocale:(id)locale
7 {
8 NSArray *allKeys = [self allKeys];
9 NSMutableString *str = [[NSMutableString alloc] initWithFormat:@"{\t\n "];
10 for (NSString *key in allKeys) {
11 id value= self[key];
12 [str appendFormat:@"\t \"%@\" = %@,\n",key, value];
13 }
14 [str appendString:@"}"];
15
16 return str;
17 }
18 @end
