保存しようとするたびにNSManagedObjectContex
、毎回1〜8秒かかります。これが私のコードです:
- (IBAction)save
{
if (self.managedObjectContext == nil) {
self.managedObjectContext = [(RootAppDelegate *)[[UIApplication sharedApplication] delegate] managedObjectContext];
}
if (self.brandText.text.length == 0 || self.modelText.text.length == 0) {
UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"Error" message:@"Please fill out the required fields" delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:nil, nil];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(125, 40, 31, 7)];
NSString *path = [[NSString alloc] initWithString:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"bullet.png"]];
UIImage *bkgImg = [[UIImage alloc] initWithContentsOfFile:path];
[imageView setImage:bkgImg];
[alertView addSubview:imageView];
[alertView show];
} else {
Hand *a = [NSEntityDescription insertNewObjectForEntityForName:@"Hand" inManagedObjectContext:self.managedObjectContext];
a.brand = self.brandText.text;
a.caliber = self.cText.text;
self.managedObjectContext = self.app.managedObjectContext;
a.notes = self.notesView.text;
a.serialNumber = self.serialNumberText.text;
a.nickname = self.nicknameText.text;
a.model = self.modelText.text;
a.gunImage = self.image.image;
a.roundsFired = [NSString stringWithFormat:@"0"];
a.cleanRounds = [NSString stringWithFormat:@"500"];
a.showBadge = [NSNumber numberWithBool:YES];
[self dismissViewControllerAnimated:YES completion:nil];
NSError *error;
if (![self.managedObjectContext save:&error]) {
UIAlertView *errorAlert = [[UIAlertView alloc]initWithTitle:@"Error" message:@"There was an internal error. \n Please restart the app and try again, Thank You" delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:nil, nil];
[errorAlert show];
}
}
}
このコードは、すべてのtextFieldsテキストを保存するだけです。とても遅い理由は何ですか?どんな助けでも大歓迎です。
