pod "KFManagedObjectContextManager"Initialization
Add the following line your AppDelegate
[[KFManagedObjectContextManager sharedInstance] setMainThreadContext:self.managedObjectContext];*managedObjectContext should be declared in your AppDelegate.
How to use:
When executing any core data code, wrap your code in the following method’s block:
- (void)handleCoreDataOperation:(void (^)(NSManagedObjectContext* context))contextBlock;
Examples:
- (User*)getCurrentUser
{
__block User* user = nil;
[KFManagedObjectContextManager handleCoreDataOperation:^(NSManagedObjectContext* context) {
user = [NSEntityDescription insertNewObjectForEntityForName:@"User"
inManagedObjectContext:context];
user.first_name = @"David";
user.last_name = @"Elsonbaty";
user.userSince = [NSDate date];
NSError *error;
if (![context save:&error]) {
NSLog(@"Whoops, saving failed: %@", [error localizedDescription]);
} else {
NSLog(@"Yay! Save Successful");
}
}];
return user;
}
- (User*)getCurrentUser
{
__block User* user = nil;
[KFManagedObjectContextManager handleCoreDataOperation:^(NSManagedObjectContext* context) {
NSFetchRequest* request = [[NSFetchRequest alloc] init];
request.entity = [NSEntityDescription entityForName:@"User"
inManagedObjectContext:context];
NSSortDescriptor* sort = [[NSSortDescriptor alloc] initWithKey:@"first_name" ascending:YES];
[request setSortDescriptors:@[ sort ]];
NSError* error = nil;
NSArray* objects = [context executeFetchRequest:request error:&error];
user = [objects lastObject];
if (!error && !user) {
user = [NSEntityDescription
insertNewObjectForEntityForName:@"User"
inManagedObjectContext:context];
user.userSince = [NSDate date];
}
}];
return user;
