Hi
I'm building my first core-data application with Xcode 3.
I have a field "sum" on my form which calculates his value using 2 other textfields "num1" and "num2".
The calculation works fine but the value from sum field doesn't save to database.
When I retype the value manually then it saves
The only code I use is for calculation
@implementation MyDocument
- (IBAction)calculate:(id)sender {
double result = [num1 doubleValue] + [num2 doubleValue];
[sum setDoubleValue:result];
}
I hope there is a easy way to fix my problem.
