+[NSManagedObjectModel setDefaultManagedObjectModel:]: unrecognized selector

[samirGT]

Hello,

I've been implementing a custom static framework for iOS and i have integrated the MagicalRecord library to my framework, everything was working well until my recent pod update ( today). Here is the MagicalRecord setup code

#pragma mark - Core Data stack
+ (void)setupCoreData {
    //1  Locate my-sdk.bundle (the bundle in the framework)
    NSString *mainBundlePath = [[NSBundle mainBundle] resourcePath];
    NSString *frameworkBundlePath = [mainBundlePath stringByAppendingPathComponent:@"my-sdk.bundle"];
    NSBundle *frameworkBundle = [NSBundle bundleWithPath:frameworkBundlePath];
    
    //2 Create an NSManagedObject Model by merging all models from the project and your framework. This simplifies saving as you can use a single persistent store coordinator to save a single managed object model.
    NSArray *bundles = [NSArray arrayWithObjects:[NSBundle mainBundle], frameworkBundle, nil];
    NSManagedObjectModel *models = [NSManagedObjectModel mergedModelFromBundles:bundles];
    
    [MagicalRecord setShouldAutoCreateManagedObjectModel:YES];
        [MagicalRecord setShouldDeleteStoreOnModelMismatch:NO];
    [NSManagedObjectModel setDefaultManagedObjectModel:models];
    
    
    // CoreData init with MagicalRecord
    NSURL *urlToStore = [[UserData applicationDocumentsDirectoryURL] URLByAppendingPathComponent:@"myName.sqlite"];
    
    // Note: we want the SQLite store in directory Documents/
    // we use NSURL instead of NSString to force our path instead of a default one in Library/Application Support/
    // To prevent a warning of incompatible type we cast to (id)
    [MagicalRecord setupCoreDataStackWithAutoMigratingSqliteStoreNamed:(id)urlToStore];
}

And to import the ShortHand categorie i am doing in .pch :

#define MR_SHORTHAND
#import 

it seems that MagicalAggregationShortHand is not imported :

+[NSManagedObjectModel setDefaultManagedObjectModel:]: unrecognized selector

I've got this lately too with other errors:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[MissingRelation deleteAllMatchingPredicate:]: unrecognized selector sent to class 0x73813c'

There should be a new podspec up on the repo. Try a ‘pod update’ command to download the updates.

I found problem in Pods-MagicalRecord-prefix.pch
After pod install I lost #define MR_SHORTHAND

file must be like this

#ifdef __OBJC__
#import <UIKit/UIKit.h>
#endif

#import "Pods-environment.h"
#ifdef __OBJC__
#define MR_SHORTHAND
#import "CoreData+MagicalRecord.h"
#endif

Thanks, adding #define MR_SHORTHAND to Pods-MagicalRecord-prefix.pch worked for me also.

Suspect the issue stems from this pull request: CocoaPods/Specs#7699

That pull request adds a subspec that you can use for the defines. We did this so the shorthand syntax wouldn't be enabled by default. You can now use MagicalRecord/Shorthand in your Podfile

@Keithbsmiley +1 . Thanks

its also important to have the "-ObjC" flag in your projects other linker flags
