当我使用UIActivityViewController与Whatsapp应用程序共享图像数据时,我收到一条提示：
This item cannot be shared. Please select a different item.
我可以将图像数据分享给除Whatsapp之外的所有其他应用程序,是否有人遇到过这样的问题？或者任何人都可以帮我解决这个问题.
解决方法
如果您想使用WhatsApp共享图像,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) 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];
}
