Question

我想在所有ActivityController中分享图片和文字，但以下代码对我不起作用：

NSString *theFileName = [[fileNameOfImage lastPathComponent] stringByDeletingPathExtension];
//      [BDGSharing shareUsingActivityController:strDataForShare urlStr:@"google.com" image:_imageview1.image];


NSString *st = [NSString stringWithFormat:@"%@.jpg",theFileName];
NSString *documentDirectory=[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
NSString *saveImagePath=[documentDirectory stringByAppendingPathComponent:st];
NSData *imageData2=UIImagePNGRepresentation(_imageview1.image);
[imageData2 writeToFile:saveImagePath atomically:YES];
NSURL *imageURL1=[NSURL fileURLWithPath:saveImagePath];
documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:imageURL1];
documentInteractionController.delegate = self;
documentInteractionController.name=strDataForShare;
 documentInteractionController.UTI = @"public.plain-text";
[documentInteractionController presentOptionsMenuFromRect:CGRectMake(1, 1, 1, 1) inView:self.view animated:YES];

如果有任何图书馆或工具包可以在whatsapp上分享，请给我建议。

Answer 1

让我们检查您的代码。第一 -

NSString *st = [NSString stringWithFormat:@"%@.jpg",theFileName];
NSData *imageData2=UIImagePNGRepresentation(_imageview1.image);

您正在保存带有PNG表示的.jpg图像，不应该使用jpeg表示吗？

UIImageJPEGRepresentation(_imageview.image, 1.0)

二 -

[imageData2 writeToFile:saveImagePath atomically:YES];

就在这里，你不确定图像是否成功保存。请添加条件

if([imageData2 writeToFile:saveImagePath atomically:YES]){

// here you are sure that the image was saved and you can use it.

}

第三 -

documentInteractionController.UTI = @"public.plain-text";

您正在分享jpg图片，为什么您的UTI是纯文本？不应该是public.image吗？

尝试解决这些问题，您的代码应该能够成功运行。
