本文介绍了如何使用Objective-C在NSLog中以中文方式输出数组和字典的内容。对于数组，通过遍历并拼接每个对象的description实现；对于字典，则先遍历所有key，然后结合key及其对应value的description进行拼接。

数组思想：将数组中的对象的description，一个一个拼接到一个总字符串，然后输出

字典思想：遍历字典的allkeys，根据单个key，每次先拼接key的description，再拼接key对应的value的description。

#pragma mark - NSArray 和 NSDictionary的两个类目 chinese

@interface NSArray (chinese)

- (NSString *)descriptionWithLocale:(id)locale;

@end

@interface NSDictionary (chinese)

- (NSString *)descriptionWithLocale:(id)locale;

@end

@implementation NSArray (chinese)

- (NSString *)descriptionWithLocale:(id)locale
{

    
    NSMutableString *strM = [NSMutableString string];
    [strM appendString:@"(\n"];
    
    for (id obj in self) {
        [strM appendFormat:@"\t\t%@,\n", obj];
    }
    [strM appendString:@")"];
    
    return strM;
}



@end


@implementation NSDictionary (chinese)

- (NSString *)descriptionWithLocale:(id)locale
{
    
    NSMutableString *strM = [NSMutableString string];
    [strM appendString:@"{\n"];
    
    for (id obj in [self allKeys]) {
        [strM appendFormat:@"\t\t%@,", obj];
        
        [strM appendFormat:@"%@\n", self[obj]];
    }
    
    [strM appendString:@"}"];
    
    return strM;
}


@end
