I am developing Alarm Clock. I want to compare a time now and setTime. Is it possible to compare in minutes only.
My Problem is NSDate will compare in seconds, for example 9:38:50 is not equal to 9:38:00. how can I compare in minutes?

首先,将其转换为UNIX,无视微秒。
NSUInteger time1 = (NSUInteger)[date1 timeIntervalSince1970];
NSUInteger time2 = (NSUInteger)[date2 timeIntervalSince1970];
Ignore seconds.
time1 = time1 - (time1 % 60);
time2 = time2 - (time2 % 60);
现在,你可以安全比较。
if (time1 == time2) {
NSLog(@"Bingo");
}
