如何使用数组获取和设置Core Data Entity的属性？

Question

我有一个CoreData实体，（myEntity），它有10个属性。有没有办法在数组中获取10个属性并使用所述数组设置属性值？

例如：

//To get the property:

NSArray *arrayOfProperties = <Some command>;

...

//and then to set the property value,instead of:
myEntity.property1 = <value>;
//set the property like so:
[[arrayOfProperties objectAtIndex:1] <some command to set the value>];

Answer 1

如下所示：

// Create the entity in the managed object context:
    MyEntity *myEntity = (MyEntity *)[NSEntityDescription insertNewObjectForEntityForName:@"MyEntity" inManagedObjectContext:[self managedObjectContext]];

// Set the properties of the entity:
    entity.property1 = arrayOfProperties[0];
    entity.property2 = arrayOfProperties[1];
    entity.property3 = arrayOfProperties[2];
    // etc...
