Question

I know I am probably missing something pretty basic here, but I am trying to convert a number entered on a UITextField from a NSString into a NSNumber as follows:

self.currentServer.port = [NSNumber numberWithInt:[addressPortTextField.text doubleValue]];
NSLog(@"Port: %@ / %@", addressPortTextField.text, self.currentServer.port);

The number in self.currentServer.port is 50000

The NSLog shows the following:

Port: 50000 / -15536

I don’t get what I am doing wrong here? I’ve tried with doubleValue, intValue, integerValue.

* I found the Problem **

self.currentServer.port is a coredata field of type Integer16. 50000 is to large for that field size, I updated the database to Integer32 and all is well now.

This line is wrong:

 self.currentServer.port = [NSNumber numberWithInt:[addressPortTextField.text doubleValue]];

and can be the source of the problem. You are converting the text to double and then saving the value in an int. If you try:

self.currentServer.port = [NSNumber numberWithInteger:[addressPortTextField.text integerValue]];

it is also important how have you defined the currentServer.port.
