将NSDate转换为NSString

Question

可能重复:
将NSDate转换为NSString
将字符串转换为nsdate

目前我有这个代码.它用于向日历添加事件.

[...]
event.startDate = [[NSDate date] dateByAddingTimeInterval:86400];
event.endDate = [[NSDate date] dateByAddingTimeInterval:90000];

我需要的是添加到特定开始日期和结束日期的代码,这就是NSString派上用场的地方.但到目前为止我还没有运气转换它.

参考此代码:

NSString到NSDate

NSString *dateString = @"01-02-2010";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
// this is imporant - we set our input date format to match our input string
// if format doesn't match you'll get nil from your string, so be careful
[dateFormatter setDateFormat:@"dd-MM-yyyy"];
NSDate *dateFromString = [[NSDate alloc] init];
// voila!
dateFromString = [dateFormatter dateFromString:dateString];
[dateFormatter release];

NSDate转换为NSString:

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"dd-MM-yyyy"];
NSString *strDate = [dateFormatter stringFromDate:[NSDate date]];
NSLog(@"%@", strDate);
[dateFormatter release];

希望它能帮到你
