计算两个日期之间相差几天几小时几分钟
NSDateFormatter

* senddate=[
NSDate
date
];
//结束时间
NSDate
*endDate = [dateFormatter
dateFromString
:
@"2014-6-24 00:00:00"
];
//当前时间
NSDate
*senderDate = [dateFormatter
dateFromString
:[dateFormatter
stringFromDate
:senddate]];
//得到相差秒数
NSTimeInterval
time=[endDate
timeIntervalSinceDate
:senderDate];
int
days = ((
int

[CATransaction begin];
