UIActivityViewController使用

UIActivityViewController

在使用了QQ、微信等的原生与第三方分享SDK之后,我更喜欢iOS自带分享框架UIActivityViewController，UIActivityViewController继承自UIViewController，简直不能更加便捷简单了，也不用去申请QQ、微信（每年¥300）等的key与id了，好了下面就来看UIActivityViewController的基本用法，自定义有空再写。一定要记得判断iPad环境，不然在iPad上直接present要crash，且crash原因会是UIPopoverPresentationController (<_UIAlertControllerActionSheetRegularPresentationController: 0x7fce54d70b50>) should have a non-nil sourceView or barButtonItem set before the presentation occurs.这就需要你判断为iPad环境时需要pop，加上popoverPresentationController.sourceView就好了。

NSString *textToShare = @"我就是喜欢踩坑呢，咋的了。生活不止眼前的苟且，还有翔和未来的苟且。";
UIImage *imageShare = [UIImage imageNamed:@"这儿放你自己的图片"];
NSURL *urlShare = [NSURL URLWithString:@"http://www.jianshu.com/u/9ab932a98604"];
NSArray *activityItems = @[textShare, imageShare, urlShare];
UIActivityViewController *actVC = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
//下面的excludedActivityTypes填写你需要剔除的（比如打印UIActivityTypePrint，短信UIActivityTypeMessage）,不写excludedActivityTypes这一行即使用系统默认的，好了，我们来看一下excludedActivityTypes的所有值。

actVC.excludedActivityTypes = @[UIActivityTypeMessage,UIActivityTypePrint,UIActivityTypeSaveToCameraRoll,UIActivityTypeAddToReadingList,UIActivityTypePostToFlickr,UIActivityTypePostToVimeo,UIActivityTypeAirDrop];
//这儿一定要做iPhone与iPad的判断，因为这儿只有iPhone可以present，iPad需pop，所以这儿actVC.popoverPresentationController.sourceView = self.view;在iPad下必须有，不然iPad会crash，self.view你可以换成任何view，你可以理解为弹出的窗需要找个依托。
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
    actVC.popoverPresentationController.sourceView = self.view;
    [self presentViewController:actVC animated:YES completion:nil];
} else {
    [self presentViewController:actVC animated:YES completion:nil];
}
