I am using NSUserDefaults to store some data. On first run of the
application, I check for the data, and if it's not been set already, I set
it.
I however get warnings in my code. In my .h I set up my variables, and then
in my .m:
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
alarm1_hour = [prefs integerForKey:@"alarm1Hour"];
if( alarm1_hour == NULL ){
NSLog(@"alarm 1 hour is null" );
}
Should I use a temporary variable to check instead of the variable with the
pointer? Or are these warnings okay to ignore?
