Thanks alot..such a nice tutorial..clearly explained step by step..

My software errors on:

[self.device setValue:self.nameTextField.text forKey:@”name”];

in:

if (self.device) {
// Update existing device
[self.device setValue:self.nameTextField.text forKey:@”name”];
[self.device setValue:self.versionTextField.text forKey:@”version”];
[self.device setValue:self.companyTextField.text forKey:@”company”];
}

What would be the preseason for this?

how lucky I am for finding this tutorial
thanx for the help

Hi! Great tutorial! They’re a big help. Though I’m still having trouble fully understanding the Objective C language, little by little, I’m gaining more confidence in iOS programming thanks to you. 🙂 Maybe you could do a tutorial on Magical Record next? Hehe. I’ll look forward to it.

even though it is deleted. if i run my code again tableview still presenting old data. in your code u r just removing devices array. not data in database

I wonder if it’s a good idea to separate the Core Data stack into it’s own file so it’s not inside AppDelegate? Also any other tricks to make it more “professional” looking would be great 🙂
