Question

i have this code in my overridden drawRect method


NSDate *date = [NSDate date];
NSCalendar *calendar = [NSCalendar currentCalendar];
unsigned int unitFlags = NSHourCalendarUnit|NSMinuteCalendarUnit|NSSecondCalendarUnit;
NSDateComponents *comp = [calendar components:unitFlags fromDate:date];
NSInteger h = [comp hour];
NSInteger m = [comp minute];
NSInteger s = [comp second];
NSLog(@"%i,%i,%i", h,m,s);
NSLog(@"test");
[date release];
[calendar release];
[comp release];


I am calling drawRect using setNeedsDisplay from my custom method (timer based after each 1 secon). It runs only once and then app exit automatically. If i comment out all the code and just write
NSLog(@”test”);
then application works ok, it logs “test” after each 1 sec.

All three of the objects you’re releasing are autoreleased. You shouldn’t call release on them explicitly.
