Extremely High Anonymous VM and App Crash - ios

Question

I have a really big problem that I can't handle. My app uses iBeacons to show views and load some pics stored in CoreData, but well, thats not the real question.
I'm loading some pics from parse to core data then retrieved from core data to be displayed.
When i change from one view to another i assume that it can increase, but when i quit the view could be possible to release memory? I don't know it I'm explaining it very well, but i hope you can understand me and help me as much as you can.
I'm using Xcode 5.1.1 and iOS 7.1 on my iPad
Now I'm using instruments to try to see what's going on, and this is what i get.
Allocations:
I think i'm not doing it wrong, loading images like this, dunno what is the problem :_(
self.itemsSection1 = [[NSMutableArray alloc] init];
self.generalImages1 = [[NSMutableArray alloc] init];
[self fillArraysWithItems:self.itemsSection1 section:#"1"];
[self fillArraysWithGeneralImages:self.generalImages1 section:#"1"];
self.itemImages = [NSArray
arrayWithObjects:[UIImage imageWithData:self.itemsSection1[0][#"image"]],
[UIImage imageWithData:self.itemsSection1[1][#"image"]],
[UIImage imageWithData:self.itemsSection1[2][#"image"]],
[UIImage imageWithData:self.itemsSection1[3][#"image"]],
[UIImage imageWithData:self.itemsSection1[4][#"image"]], nil];
for (int i=0; i<self.generalImages1.count; i++) {
[self.itemSliderImages addObject:[UIImage imageWithData:self.generalImages1[i][#"image"]]];
}
generalImage.image = [UIImage imageWithData:self.generalImages1[0][#"image"]];
self.img_elements.image = generalImage.image;
self.navBar_title.title = #"Catering";
FillArraysWithItems:
-(void)fillArraysWithItems: (NSMutableArray*)item section:(NSString*)section{
AppDelegate *delegate = (AppDelegate*)[[UIApplication sharedApplication] delegate];
NSEntityDescription *entity = [NSEntityDescription entityForName:#"Item" inManagedObjectContext:delegate.managedObjectContext];
NSFetchRequest *fetchedRequest = [[NSFetchRequest alloc]init];
[fetchedRequest setEntity:entity];
self.allItemInfo = [[delegate.managedObjectContext executeFetchRequest:fetchedRequest error:nil] mutableCopy];
NSLog(#"\n\nAllItems:%#\n", self.allItemInfo);
for (NSManagedObjectContext *obj in self.allItemInfo) {
//Save data from CoreData to arrays
NSLog(#"\n\nObject:\n%#", obj);
NSString *micro = #"micro_off.png";
NSString *oven = #"oven_off.png";
NSString *recycle = #"recycle_off.png";
NSString *biodeg = #"biodeg_off.png";
NSString *liquid = #"liquid_off.png";
NSString *perso = #"perso_off.png";
NSLog(#"\n\nName:%#\nRef:%#\nPricePack:%#\nUnitPrice:%#\nunitsPack:%#",[obj valueForKey:#"name"], [obj valueForKey:#"reference"],[obj valueForKey:#"pricePack"], [obj valueForKey:#"priceUnity"], [obj valueForKey:#"unitsPack"]);
NSLog(#"\n\nMicro:%#\nOven:%#\nRecycle:%#\nBiodeg:%#\nLiquid:%#\nPerso:%#\n", [obj valueForKey:#"micro"], [obj valueForKey:#"oven"], [obj valueForKey:#"recycle"], [obj valueForKey:#"bio"], [obj valueForKey:#"liquid"], [obj valueForKey:#"perso"]);
if ([[obj valueForKey:#"section"] isEqual:section]) {
if ([[obj valueForKey:#"micro"] isEqual: #1]) {
micro = #"micro_on.png";
}
if ([[obj valueForKey:#"oven"] isEqual: #1]) {
oven = #"oven_on.png";
}
if ([[obj valueForKey:#"recycle"] isEqual: #1]) {
recycle = #"recycle_on.png";
}
if ([[obj valueForKey:#"bio"] isEqual: #1]) {
biodeg = #"biodeg_on.png";
}
if ([[obj valueForKey:#"liquid"] isEqual: #1]) {
liquid = #"liquid_on.png";
}
if ([[obj valueForKey:#"perso"] isEqual: #1]) {
perso = #"perso_on.png";
}
[item addObject:#{#"name": [obj valueForKey:#"name"],
#"pricePack": [obj valueForKey:#"pricePack"],
#"priceUnity": [obj valueForKey:#"priceUnity"],
#"reference": [obj valueForKey:#"reference"],
#"unitsPack": [obj valueForKey:#"unitsPack"],
#"micro": [UIImage imageWithContentsOfFile:micro],
#"oven": [UIImage imageWithContentsOfFile:oven],
#"recycle": [UIImage imageWithContentsOfFile:recycle],
#"bio": [UIImage imageWithContentsOfFile:biodeg],
#"liquid": [UIImage imageWithContentsOfFile:liquid],
#"perso": [UIImage imageWithContentsOfFile:perso],
#"image": [UIImage imageWithContentsOfFile:[obj valueForKey:#"image"]]}];
}
}
NSError *error;
BOOL isFetched = [delegate.managedObjectContext save:&error];
NSLog(#"Arrays successfully filled: %d", isFetched);
}
And this is the error I get when [item addObject...
