我有這個代碼泄漏。性能工具泄漏告訴我，這是在這一行：泄漏從plist加載數據到CoreData
NSArray *fakeData = [[NSArray alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"FakeData" ofType:@"plist"]];
我找不出是怎麼回事。我加載的plist有3個NSDictionary元素，和截圖中的泄漏一樣。每個詞典有3個字符串。
整個代碼：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//Ładowanie danych
if (![[FlickrFetcher sharedInstance] databaseExists]) {
NSArray *fakeData = [[NSArray alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"FakeData" ofType:@"plist"]];
for (NSDictionary *element in fakeData) {
//Wypełnianie CoreData danymi
Photo *newPhoto = (Photo *)[NSEntityDescription insertNewObjectForEntityForName:@"Photo"
inManagedObjectContext:[[FlickrFetcher sharedInstance] managedObjectContext]];
NSLog(@"Creating Photo: %@", [element objectForKey:@"name"]);
[newPhoto setName:[element objectForKey:@"name"]];
[newPhoto setImageURL:[element objectForKey:@"path"]];
NSLog(@"Person is: %@", [element objectForKey:@"user"]);ŕŕŕ
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"name == %@", [element objectForKey:@"user"]];
NSMutableArray *peopleArray = (NSMutableArray *)[[FlickrFetcher sharedInstance] fetchManagedObjectsForEntity:@"Person"
withPredicate:predicate];
NSEnumerator *enumerator = [peopleArray objectEnumerator];
Person *person;
BOOL exists = FALSE;
while (person = [enumerator nextObject]) {
NSLog(@"Person is: %@", person.name);
if ([person.name isEqualToString:[element objectForKey:@"user"]]) {
exists = TRUE;
NSLog(@"-- Person exists: %@", person.name);
[newPhoto setOwner:person];
}
}
if (!exists) {
Person *newPerson = (Person *)[NSEntityDescription insertNewObjectForEntityForName:@"Person"
inManagedObjectContext:[[FlickrFetcher sharedInstance] managedObjectContext]];
[newPerson setName:[element objectForKey:@"user"]];
NSLog(@"Person created: %@", newPerson.name);
[newPhoto setOwner:newPerson];
}
NSError *error;
if (![[[FlickrFetcher sharedInstance] managedObjectContext] save:&error]) {
NSLog(@"Unresolved error %@ %@", error, [error userInfo]);
exit(-1);
}
[fakeData release];
}
}
//Person Navigation Controller
personNavigationController = [[UINavigationController alloc] init];
PersonListViewController *personListViewController = [[PersonListViewController alloc] initWithStyle:UITableViewStylePlain];
personListViewController.title = @"Contacts";
[personNavigationController pushViewController:personListViewController animated:NO];
[personListViewController release];
//Recent Photo Navigation Controller
recentPhotoNavigationController = [[UINavigationController alloc] init];
RecentPhotoViewController *recentPhotoViewController = [[RecentPhotoViewController alloc] init];
recentPhotoViewController.title = @"Recent";
UITabBarItem *item = [[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemRecents tag:1];
recentPhotoViewController.tabBarItem = item;
[item release];
[recentPhotoNavigationController pushViewController:recentPhotoViewController animated:NO];
[recentPhotoViewController release];
//Tab Bar Controller
tabBarController = [[UITabBarController alloc] init];
tabBarController.viewControllers = [NSArray arrayWithObjects:
personNavigationController,
recentPhotoNavigationController,
nil];
[window addSubview:tabBarController.view];
[window makeKeyAndVisible];
return YES;
