我有一系列的约会。预约可以持续多天。例如
Start --> 20/03/2014
END --> 23/03/2014
但我想在3月20日，21日，22日和23日的日历视图中显示约会。所以我写了下面这个函数。
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，它会在其中添加NSDictionary约会。但是当i = 2时，它会增加第二个NSDictionary，但第一个NSDictionary中的约会被修改为与第二个约会相同的约会。
请查看下面的NSLOG并查看app_start

答案 0 :(得分：2)
将循环中的Appointment *newAppointment = appointmentValue;更改为
Appointment *newAppointment = [[Appointment alloc] init];
分配newAppointment = appointmentValue;时，每次更改都会对相同的实例进行编辑。
答案 1 :(得分：2)
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，您需要使用copy
Appointment *newAppointment = [appointmentValue copy];
您可能必须实现自己的＆＃39; copyWithZone：`以确保正确复制所有属性。
或者正如Akhilrajtr建议分配新版本并复制所需的所有属性
