It's difficult for me to express my problem so I will write a simple example of it. I have 2 classes, MyclassA and MyclassB.
@interface MyclassA
@property (nonatomic, assign) int *ID;
@property (nonatomic, strong) MyclassB *secondclass;
@end
@implementation MyclassA
-(id)init
{
self.ID = 1;
MyclassB *sec = [[MyclassB alloc] init];
sec.age = 10;
sec.weight = 35;
self.secondclass = sec;
return self;
}
MyclassB:
@interface MyclassB
@property (nonatomic, assign) int age;
@property (nonatomic, assign) int weight;
@end
When I place a breakpoint at
return self;
the value of self.secondclass is null.
What am I doing wrong?
You are creating a new object of the MyClassB. You should initialize the property secondClass in the init method instead of assigning the reference of another instance of MyClassB.
-(id)init
{
self.ID = 1;
self.secondclass = [[MyclassB alloc] init];
self.secondclass.age = 10;
self.secondclass.weight = 35;
return self;
}
