在目标c:
NSDate *past = [NSDate date];
NSTimeInterval oldTime = [past timeIntervalSince1970];
NSString *timestamp = [[NSString alloc] initWithFormat:@"%0.0f", oldTime];
在Javascript中:
new Date().getTime();
问题在于,在目标c中,时间戳由10个数字组成,但在javascript中它有13个数字。当我比较两者的差异是在15分钟内,我总是假的。
如何在目标c中获得13位数的时间戳?

getTime()
http://www.w3schools.com/jsref/jsref_gettime.asp
Returns the number of milliseconds since 1970/01/01:
- (NSTimeInterval)timeIntervalSince1970
Returns the interval between the receiver and the first instant of 1 January 1970, GMT.
NSTimeInterval used to specify a time interval, in seconds.
所以你需要将值乘以1000以将秒转换为毫秒
NSDate *past = [NSDate date];
NSTimeInterval oldTime = [past timeIntervalSince1970];
NSString *timestamp = [[NSString alloc] initWithFormat:@"%0.0f", oldTime * 1000];
