带有自定义数据的自定义 UIActivity

Question

我有一些图像和文本想通过 Facebook、twitter 分享，它工作正常，虽然我想用我的自定义 UIActivity 分享另一组数据（活动项）

 NSLog(@"The Selected Photo Count %i",[self.selectedPhotos count]);

NSMutableArray *newArray=[[NSMutableArray alloc]init];
NSMutableArray *newArraytext=[[NSMutableArray alloc]init];



for (Shoplog * ChosenPhot in self.selectedPhotos) {

    NSString *initalTextString = [NSString
                                  stringWithFormat:@"I am Sending from my Shoplog Collection: %@",
                                  ChosenPhot.categoryname];

    [newArraytext addObject:initalTextString];
    CreateShoplogTagImage *createimagetag=[[CreateShoplogTagImage alloc]init];
    UIImage *newimage=[createimagetag Imagetag:ChosenPhot];
    NSDictionary *flurrydicttionary3=[[NSDictionary alloc]initWithObjectsAndKeys:ChosenPhot.categoryname,@"SharedCategoryname", nil];
    [Flurry logEvent:@"SharedCatalogue" withParameters:flurrydicttionary3 timed:YES];
    [newArray addObject:newimage];

}


NSMutableArray *addArray=[[NSMutableArray alloc]initWithArray:newArray];
[addArray addObjectsFromArray:newArraytext];


UIActivityViewController *activityViewController2 =[[UIActivityViewController alloc]initWithActivityItems:addArray applicationActivities:@[shopactivity]];

[self presentViewController:activityViewController2 animated:YES completion:^{}];

Answer 1

您应该继承UIActivityItemProvider 或创建符合UIActivityItemSource 的对象。传入其中的一个数组，并根据activityViewController:itemForActivityType: 调用中选择的活动让其中一些返回 nil。
