iOS开发 判定某个时间是否属于这个时间段

- (BOOL)isBetweenDate

{

//设置的是中国时间

NSString *startTime=@"13:01";

NSString *expireTime=@"20:01";

NSDate *today = [NSDate date];

NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];

// 时间格式,此处遇到过坑,建议时间HH大写,手机24小时进制和12小时禁止都可以完美格式化

[dateFormat setDateFormat:@"HH:mm"];

NSString * todayStr=[dateFormat stringFromDate:today];//将日期转换成字符串

//    todayStr=@"12:01";

today=[ dateFormat dateFromString:todayStr];//转换成NSDate类型。日期置为方法默认日期

//startTime格式为 02:22   expireTime格式为 12:44

NSDate *start = [dateFormat dateFromString:startTime];

NSDate *expire = [dateFormat dateFromString:expireTime];

NSLog(@"today today ==%@",today);

NSLog(@"start start ==%@",start);

NSLog(@"expire expire ==%@",expire);

if ([today compare:start] == NSOrderedDescending && [today compare:expire] == NSOrderedAscending)

{

NSLog(@"属于------1");

return YES;

}

else

{

NSLog(@"不属于------2");

return NO;

}

return NO;

}
