Person是PFObject的子类。
Address也是PFObject的子类。 Address的{{1}}类型为@property。
即
Person两个子类都在// Person.h
@interface Person : PFObject<PFSubclassing>
@property (retain) NSString *firstName;
@property (retain) NSString *secondName;
+ (NSString *)parseClassName;
@end
// Person.m
#import <Parse/PFObject+Subclass.h>
@implementation PP4MEAddress
@dynamic firstName;
@dynamic firstName;
+ (NSString *)parseClassName {
return @"Person";
}
// Address.h
@interface Address : PFObject<PFSubclassing>
@property (retain) Person *deliverToPerson;
@property (retain) NSString *line1;
@property (retain) NSString *line2;
+ (NSString *)parseClassName;
// Address.m
#import <Parse/PFObject+Subclass.h>
@implementation PP4MEAddress
@dynamic deliverToPerson;
@dynamic line1;
@dynamic line2;
+ (NSString *)parseClassName {
return @"Address";
}
。
在App Delegate中的方法中我想将它们设置为
e.g。
MyViewController执行此代码时，类-(void)myMethod
{
Address *address = [Address object];
address.deliverToPerson.firstName = @"John";
address.deliverToPerson.secondName = @"Smith";
address.line1 = @"123";
address.line2 = @"Main Street";
[address saveInBackground];
}
的条目将输入到Parse.com Web App上的Address。但是，唯一的列是Data Browser，objectId，createdAt和updatedAt
我想这是因为，ACL类型Address @property不是Person和allocated。
我如何克服这个问题？
我是否为
撰写自定义initialised和setter
getter在@property (retain) Person *deliverToPerson;
？
如果有，我注意到Address.m是@property，因此我需要在atomic和setter中编写锁定代码吗？
谢谢

我对parse.com并不熟悉，但我强烈认为你必须这样做
在设置关系之前分配Person对象。像
Address *address = [Address object];
address.line1 = @"123";
address.line2 = @"Main Street";
Person *person = [Person object];
person.firstName = @"John";
person.secondName = @"Smith";
address.deliverToPerson = person;
[address saveInBackground];

您必须设置PF对象 像这样
PFObject *anotherPlayer = [PFObject objectWithClassName:@"Player"];
[anotherPlayer setObject:@"DataValue" forKey:@"Name"];
