ios - NSMutableArray 中的 NSDictionary 在我的整个 for 循环中发生变化

Question

我有一组约会。约会可以持续多天。例如

Start --> 20/03/2014
END   --> 23/03/2014

但我想在我的日历 View 中显示 3 月 20 日、21 日、22 日和 23 日的约会。因此，我在下面编写了函数。

        NSMutableArray *arrAppoints = [[NSMutableArray alloc]init];
        for(Appointment *appointmentValue in matches2){
            NSDateComponents *componentsBegin = [[NSCalendar currentCalendar] components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear fromDate:appointmentValue.app_start];
            NSDateComponents *componentsEnd = [[NSCalendar currentCalendar] components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear fromDate:appointmentValue.app_end];

            if([componentsEnd day] - [componentsBegin day] == 0){
                //Appointment on same day
                UIColor *appColor = [appointmentValue getLabelbyId:[appointmentValue valueForKey:@"app_label_id"]];
                NSDictionary *dictAppointment = [[NSDictionary alloc]initWithObjectsAndKeys:appointmentValue,@"appointment",appColor,@"appColor", nil];
                [arrAppoints addObject:dictAppointment];
            }else{
                //Appointment is over multiple days
                NSInteger count = [componentsEnd day] - [componentsBegin day];
                UIColor *appColor = [appointmentValue getLabelbyId:[appointmentValue valueForKey:@"app_label_id"]];
                for (int i=0;i<=count;i++){
                    if (i==0){
                        //Store it in arrAppoints
                        NSDictionary *dictAppointment = [[NSDictionary alloc]initWithObjectsAndKeys:appointmentValue,@"appointment",appColor,@"appColor", nil];
                        //arrAppoints is the array that I pass through my dayview. (stores only the appointment for that day)
                        [arrAppoints addObject:dictAppointment];
                    }else{
                        //Store it in arrMultipleDays and get it later on the correct day
                        NSLog(@"arrDAYS 1 is %@",arrMultipleDays);
                        int daysToAdd = i;
                        NSDate *newDate1 = [appointmentValue.app_start dateByAddingTimeInterval:60*60*24*daysToAdd];
                        Appointment *newAppointment = appointmentValue;
                        newAppointment.app_start = newDate1;
                        NSLog(@"arrDAYS 1B is %@",arrMultipleDays);
                        newAppointment.app_fullday = [NSNumber numberWithInt:1];
                        NSNumber *iValue = [NSNumber numberWithInt:i];

                        NSDictionary *dictAppointment = [[NSDictionary alloc]initWithObjectsAndKeys:newAppointment,@"appointment",appColor,@"appColor",iValue,@"value", nil];
                        [arrMultipleDays addObject:dictAppointment];
                        NSLog(@"arrDAYS 2  is %@",arrMultipleDays);
                    }
                }
            }
        }

问题当 i = 1 时，它会添加一个包含约会的 NSDictionary。但是当 i = 2 它添加第二个 NSDictionary 但第一个 NSDictionary 中的约会被修改为与第二个相同的约会。

请看下面的NSLOG，寻找app_start

Answer 1

我假设您使用 appointmentValue 作为起点，以便复制相似的值，例如颜色？然后你需要使用 copy

Appointment *newAppointment = [appointmentValue copy];

您可能必须实现自己的“copyWithZone:”以确保正确复制所有属性。

或者正如 Akhilrajtr 建议的那样，分配一个新版本并复制您需要的所有属性
