对数组进行扩展方法 重写 descriptionWithLocale 方法

-(NSString *)descriptionWithLocale:(id)locale
{
    NSMutableString *string = [[NSMutableString alloc] init];
    [string appendString:@"@{"];
    id obj = nil;
    NSEnumerator *iterator = [self objectEnumerator];
    
    while ((obj=[iterator nextObject]) != nil)
    {
        [string appendFormat:@"\t%@,\n",obj];
    };
    
    [string appendString:@"}"];
    
    return string;
}
