用于打开具有特定日期的本机日历的URL方案 [英] URL scheme for opening native calendar with specific date

问题描述

我已经找到示例代码，从我的应用打开日历，但我无法在特定日期打开。

I have found the sample code to open calendar from my app, but i can't open at a specific date.

NSString* launchUrl = @"calshow://";
[[UIApplication sharedApplication] openURL:[NSURL URLWithString: launchUrl]];

有一种方法可以在lunchUrl字符串的末尾添加特定日期，

Is there a way to add specific date at the end of the "lunchUrl" string so when the user opens the calendar it displays the given date.

我已经尝试过以下格式：@calshow：//？= 2013 12 19，@calshow： /？= 2013-12-19，@calshow：//？= 2013 + 12 + 19。这些都不适合我...任何想法我做错了什么？

I have already tried the following formats: @"calshow://?=2013 12 19", @"calshow://?=2013-12-19", @"calshow://?=2013+12+19". None of these seem to work for me... any ideas what am i'm doing wrong?

推荐答案

url方案一点，找到了办法做到。主要两点是：

I played with this url scheme a little and found the way to do it. The main two points are:

1. 不要在 calshow：


2. 自参考日期（2001年1月1日）起通过时间戳记

代码：

- (void)showCalendarOnDate:(NSDate *)date
{
    // calc time interval since 1 January 2001, GMT
    NSInteger interval = [date timeIntervalSinceReferenceDate]; 
    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"calshow:%ld", interval]];
    [[UIApplication sharedApplication] openURL:url];
}

这就是我所说的：

// create some date and show the calendar with it
- (IBAction)showCalendar:(id)sender
{
    NSDateComponents *comps = [[NSDateComponents alloc] init];
    [comps setDay:4];
    [comps setMonth:7];
    [comps setYear:2010];

    NSCalendar *cal = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];

    [self showCalendarOnDate:[cal dateFromComponents:comps]];
}

也许你应该考虑 calshow： / code>不是一个公共网址方案，所以也许苹果会皱着眉头这样使用它。或者也许他们不会（我没有研究过）。

Perhaps you should take into account that calshow: is not a public url scheme, so maybe Apple would frown upon using it in this way. Or maybe they wouldn't (I haven't researched that).
