Question

I have UserDetails class:

@interface UserDetails: NSObject{

  NSString* resourceName;
  NSNumber* resourceId;

  }

I have an object(“user”) of this class in class B which I am passing in another Class C. Now I need to store the resourceNames of different users in an array and display it in another class C(TableviewController). I am using the following statements in class C:

NSMutableArray *arr (declaration)

Implementation:

 arr=[[NSMutableArray array] retain];
 arr=user1.resourceName;  (user1 is an object of UserDetails data class).

Error : Incompatible pointer types assigning to “NSMutableArray” from “NSString”.

Can you help me with this?

Answer 1

You are directly assigning stringValue “resourceName” to “arr”,which will give u error.If u wanna store the resourceName in array ..try this

arr=[[NSMutableArray array] retain]; // your initialization
 [arr addObject:user1.resourceName];
