如何获取NSMutableArray特定对象

-1

我想这个数组列表在下周日和周一的文本对象获取并保存在另一个数组中。换句话说获取日期和星期几名称的对象都得到并保存在阵列中如何获取NSMutableArray特定对象

请帮助我该如何做到这一点。我很努力，但没有得到正确答案。

NSDateComponents *components; 
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init]; 
[dateFormat setDateFormat:@"dd-MM-yyyy"]; 

NSDate *startDate = [dateFormat dateFromString:@"25-11-2016"]; 
NSDate *endDate = [dateFormat dateFromString:@"7-12-2016"]; 

[dateFormat setDateFormat:@"dd-MM-yyyy, EEEE"]; 

components = [[NSCalendar currentCalendar] components:NSDayCalendarUnit fromDate:startDate toDate:endDate options:0]; 

int days = [components day]; 



for (int x = 0; x <= days; x++) { 
    [mutable_ary addObject:[dateFormat stringFromDate:startDate]]; 
    NSLog(@"%@",[dateFormat stringFromDate:startDate]); 

    startDate = [startDate dateByAddingTimeInterval:(60 * 60 * 24)]; 

} 
NSLog(@"%@",mutable_ary); 

{ 
"25-11-2016, Friday", 
"26-11-2016, Saturday", 
"27-11-2016, Sunday", 
"28-11-2016, Monday", 
"29-11-2016, Tuesday", 
"30-11-2016, Wednesday", 
"01-12-2016, Thursday", 
"02-12-2016, Friday", 
"03-12-2016, Saturday", 
"04-12-2016, Sunday", 
"05-12-2016, Monday", 
"06-12-2016, Tuesday", 
"07-12-2016, Wednesday" 
}

输出：

{ 

"27-11-2016, Sunday", 
"28-11-2016, Monday", 
"04-12-2016, Sunday", 
"05-12-2016, Monday", 
}

让我们来看看你有什么至今。 –

@ElTomato请检查我更新的问题 –

请发布您的代码。 – shallowThought

试试这个：

NSMutableArray *arrList = [[NSMutableArray alloc]initWithObjects:@"25-11-2016, Friday", 
          @"26-11-2016, Saturday", 
          @"27-11-2016, Sunday", 
          @"28-11-2016, Monday", 
          @"29-11-2016, Tuesday", 
          @"30-11-2016, Wednesday", 
          @"01-12-2016, Thursday", 
          @"02-12-2016, Friday", 
          @"03-12-2016, Saturday", 
          @"04-12-2016, Sunday", 
          @"05-12-2016, Monday", 
          @"06-12-2016, Tuesday", 
          @"07-12-2016, Wednesday", nil]; 

NSMutableArray *result = [[NSMutableArray alloc]init]; 
for (id element in arrList){ 
    NSString *str = element; 
    if ([str containsString:@"Monday"] || [str containsString:@"Sunday"]){ 
     [result addObject:element]; 
    } 
} 

// print result 
NSLog(@"%@",result);

你在吗？请解决我有关这个问题的更多问题。 –

NSArray *input = @[@"25-11-2016, Friday", 
        @"26-11-2016, Saturday", 
        @"27-11-2016, Sunday", 
        @"28-11-2016, Monday", 
        @"29-11-2016, Tuesday", 
        @"30-11-2016, Wednesday", 
        @"01-12-2016, Thursday", 
        @"02-12-2016, Friday", 
        @"03-12-2016, Saturday", 
        @"04-12-2016, Sunday", 
        @"05-12-2016, Monday", 
        @"06-12-2016, Tuesday", 
        @"07-12-2016, Wednesday"]; 

NSMutableArray *days = [NSMutableArray arrayWithArray: @[@"Sunday",@"Monday"]]; 
NSMutableArray *output = [NSMutableArray new]; 
for(NSString *day in days){ 
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF contains %@",day]; 
          NSArray *filtered = [input filteredArrayUsingPredicate:predicate]; 
    [output addObjectsFromArray:filtered]; 
} 

NSLog(@"%@",output);
