当我使用UIActivityViewController
向Whatsapp
应用分享图片数据时,我收到提醒信息:
此项目无法共享。请选择其他项目。
我可以将图片数据分享给除{{1}}以外的所有其他应用,是否有人遇到过此类问题?或者任何人都可以帮我解决这个问题。
如果有人想检查代码,那么评论会在需要时分享。

如果您想使用WhatsApp分享图片,请使用以下代码:
if ([[UIApplication sharedApplication] canOpenURL: [NSURL URLWithString:@"whatsapp://app"]]){
UIImage * iconImage = [UIImage imageNamed:@"my_account.png"];
NSString * savePath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/whatsAppTmp.wai"];
[UIImageJPEGRepresentation(iconImage, 1.0) writeToFile:savePath atomically:YES];
_documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:savePath]];
_documentInteractionController.UTI = @"net.whatsapp.image";
_documentInteractionController.delegate = self;
[_documentInteractionController presentOpenInMenuFromRect:CGRectMake(0, 0, 0, 0) inView:self.view animated: YES];
} else {
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"WhatsApp not installed." message:@"Your device has no WhatsApp installed." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
}
