“date1 == date2
”不是一种有效的比较方式吗?如果不是,正确的替代方法是什么?
这是我的代码:
- (NSDate*) dateWithNoTime {
unsigned int flags = NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit;
NSCalendar* calendar = [NSCalendar currentCalendar];
NSDateComponents* components = [calendar components:flags fromDate:self];
NSDate* dateOnly = [calendar dateFromComponents:components];
return dateOnly;
}
- (BOOL) sameDayAsDate:(NSDate*)dateToCompare {
NSDate *date1 = [self dateWithNoTime];
NSDate *date2 = [dateToCompare dateWithNoTime];
return date1 == date2; // HERE IS WHERE THINGS SEEM TO FAIL
}
isEqual:
