Implemetation of videos in video with blur effect in objective c

Using NSExpression to combine entities and return an NSArray or NSArray elements

I would like the NSFetchRequest for my UITableViewController to group similar records (entities) based upon a particular attribute. I currently do a two-step process, but I believe there might be someway to use an + (NSExpression *)expressionForAggregate:(NSArray *)collection.
Could someone help with the appropriate code?
Here's the code for my two step process that returns an array of an array:
+(NSArray *)getTopQforDogByProgram2:(Dog *)dog
inProgram:(RunProgramTypes)programType
inManagedContext:(NSManagedObjectContext *)context {
NSString *searchString;
NSFetchRequest *request = [NSFetchRequest fetchRequestWithEntityName:#"Run"];
request.predicate = [NSPredicate predicateWithFormat:[NSString stringWithFormat:#"dog.callName = '%#'",dog.callName]];
NSSortDescriptor *classSortDescriptor = [NSSortDescriptor sortDescriptorWithKey:#"runClass" ascending:NO];
request.sortDescriptors = [NSArray arrayWithObject:classSortDescriptor];
NSError *error = nil;
NSArray *dataArray = [context executeFetchRequest:request error:&error];
NSMutableArray *returnArray = [[NSMutableArray alloc] init];
if ( [dataArray count] > 0 ) {
NSMutableArray *pointArray = [[NSMutableArray alloc] init];
for ( Run *run in dataArray ) {
if ( ! [returnArray count] ) {
[pointArray addObject:run];
[returnArray addObject:pointArray];
} else {
BOOL wasSame = FALSE;
for ( NSMutableArray *cmpArray in returnArray ) {
Run *cmpRun = [cmpArray lastObject];
if ( cmpRun.runClass == run.runClass ) {
[cmpArray addObject:run];
wasSame = TRUE;
break;
}
}
if ( ! wasSame ) {
pointArray = [[NSMutableArray alloc] init];
[pointArray addObject:run];
[returnArray addObject:pointArray];
}
}
}
}
return returnArray;
}

You could use a fetch results controller to do the sectioning for you like this:
NSFetchedResultsController* controller = [[NSFetchedResultsController alloc] initWithFetchRequest:request
managedObjectContext:context
sectionNameKeyPath:#"runClass"
cacheName:nil];
NSMutableArray* sections = [[NSMutableArray alloc] initWithCapacity:[controller sections] count];
for (id<NSFetchedResultsSectionInfo> section in [controller sections]) {
NSMutableArray* sectionCopy = [NSMutableArray arrayWithArray:[section objects]];
[sections addObject:sectionCopy];
}
Or do it yourself with: (given that the results are sorted by runClass)
NSMutableArray* sections = [NSMutableArray new];
NSMutableArray* currentSection = [NSMutableArray new];
for (Run* run in dataArray) {
Run* lastObject = (Run*)[currentSection lastObject];
if (lastObject && (run.runClass == lastObject.runClass)) {
currentSection = [NSMutableArray new];
[sections addObject:currentSection];
}
[currentSection addObject:run];
}

mkannotation automatic/default callout not happening

i added an annotation and in viewforannotation i set canshowcallout and selected the annotation as well but it aint getting selected...
-(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{
currentCoordinates = newLocation.coordinate;
ParkPlaceMark *pa = [[ParkPlaceMark alloc] init];
pa.coordinate = currentCoordinates;
pa.title = #"POI";
pa.title2 = #"CUrrent Locn";
pa.subtitle = #"Drag and drop to adjust the position if necessary";
[mapView addAnnotation:pa];
[pa release];
}
- (MKAnnotationView *)mapView:(MKMapView *)map
viewForAnnotation:(ParkPlaceMark*)annotation {
MKAnnotationView *test=[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:#"parkingloc"];
if([annotation.title caseInsensitiveCompare:#"POI"] == NSOrderedSame)
{
test.annotation = annotation;
test.userInteractionEnabled = YES;
test.draggable = YES;
// test.pinColor = MKPinAnnotationColorRed;
[test setImage:[UIImage imageNamed:#"marker3.png"]];
[test setEnabled:YES];
[test setCanShowCallout:YES];
[test setDragState:MKAnnotationViewDragStateEnding animated:YES];
[self.mapView selectAnnotation:test.annotation animated:YES];
return test;
}
}

I had added custom animation so
[self.mapView selectAnnotation:test.annotation animated:YES];
was not working . The correct code is :
[self.mapView selectAnnotation:test.annotation animated:NO];

That’s simply too much code to check for errors. Make sure you can start the export session, that you really get pixel buffers for your images, that the writer is ready for receiving more data, that the buffer gets appended without errors, that the export session finishes with success and that the output movie file exists and actually contains some data. Only then you can try and save it to the system photo album. Check all the available error information along the way so that you know where the thing breaks for the first time. (Another thing is that you are simply taking code from the web and pasting it together, which is simply not going to work for AV programming.)

Yes, I had the same error:
Error Domain=AVFoundationErrorDomain Code=-11823 "Cannot Save" UserInfo=0x193ce0 {NSLocalizedRecoverySuggestion=Try saving again., NSUnderlyingError=0x179e40 "The operation couldn’t be completed. (OSStatus error -12412.)", NSLocalizedDescription=Cannot Save}
But only on simulator, when I ran on a device, the save to the photo library worked just fine.

How do you get an SQLITE database (Mydb.db) to load every time you start the iPhone App?

I have an app that access a static SQLITE database when running. A user or application is not allowed to alter or update this database. However, I need to add records or change field content to keep up with changing URLs etc. I use MesaSQLite to update the single table. But when I re-open the app in Xcode Simulator, none of the changes took effect. It's as if the app did not reload the updated database.
How can I get a reload to take place? Keep in mind that I'm still covered in shrink wrap because I'm so new to coding !!!

I'm not really sure of the SQL part. but I think that you will need to reload the table content after getting the update from the database. If you post some code, I can help you better. Here's how to reload the table:
[myTable reloadData];
And you will need to update the table with the new data in
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

This is an IOS4.2 iPhone app. Here is the code for accessing and displaying the sort results of the database. The purpose is to use the database to sort delegates by event and state, then display the results. The displayed delegates are linked to a website. Again, the user and the app DO NOT alter the database, it's static. I use an SQLite editor to make changes and import them back into the databases' single table. I just need the table reloaded when this portion of the code runs.
I'll need to know what code and where to insert it for table reload.
Thanks for your help !!!!!
