我想将当前日期与另一个日期进行比较,如果该日期早于当前日期,那么我应该停止下一个操作.我该怎么做？
我今天的日期是yyyy-MM-dd格式.我需要检查这个条件
- if([displaydate text]<currentdate)
- {
- //stop next action
- }
这里如果displaydate小于今天的日期,那么它必须输入该条件.
解决方法
- NSDate *today = [NSDate date]; // it will give you current date
- NSDate *newDate = [dateFormatter dateWithString:@"xxxxxx"]; // your date
- NSComparisonResult result;
- //has three possible values: NSOrderedSame,NSOrderedDescending,NSOrderedAscending
- result = [today compare:newDate]; // comparing two dates
- if(result==NSOrderedAscending)
- NSLog(@"today is less");
- else if(result==NSOrderedDescending)
- NSLog(@"newDate is less");
- else
- NSLog(@"Both dates are same");
