NSString时间格式为int64_t

Question

I have an NSString that represents a time in mm:ss format. How do i convert it in int64_t so i can submit it as a score in game center?

If you wanted to be rigorous you could use an NSDateFormatter to convert to an NSDate then get an NSTimeInterval from that; if you wanted to be more direct then you might try something as simple as:

NSArray *components = [string componentsSeparatedByString:@":"];
if([components count] != 2)
{
    // some error condition
    return;
}

int64_t totalSeconds = ([[components objectAtIndex:0] integerValue] * 60) +
                             [[components objectAtIndex:1] integerValue];
