Ios Instagram hook com.Instagram.exclusivegram并非如此排他性

据我所知，如果您真的只希望instagram+使用正确的扩展名.ig，则必须使用com.instagram.photo来获取documentinteractioncontroller的UTI的常规选项和com.instagram.exclusivegram

出于某种原因，我看到了多种选择，而不仅仅是我想要的Instagram

我忘了什么吗？有不同的做法吗

UIImage *image = (UIImage *)[info valueForKey:UIImagePickerControllerOriginalImage];

NSURL *instagramURL = [NSURL URLWithString:@"instagram://"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) {
    CGRect rect = CGRectMake(0,0,0,0);
    CGRect cropRect=CGRectMake(0,0,612,612);
    // ig voor gewone instagram, igo voor exclusive instagram
    NSString *jpgPath=[NSHomeDirectory() stringByAppendingPathComponent:@"Documents/temp/photo.igo"];
    CGImageRef imageRef = CGImageCreateWithImageInRect([image CGImage], cropRect);
    UIImage *img = [[UIImage alloc] initWithCGImage:imageRef];
    CGImageRelease(imageRef);
    [UIImageJPEGRepresentation(img, 1.0) writeToFile:jpgPath atomically:YES];

    NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@",jpgPath]];
    // exclusive zou direct in de instagram app moeten openen, helaas toont hij meerdere opties met instagram ergenes helemaal achteraan
    self.documentInteractionController.UTI = @"com.instagram.exclusivegram";
    self.documentInteractionController = [self setupControllerWithURL:igImageHookFile usingDelegate:self];
    self.documentInteractionController.annotation = [NSDictionary dictionaryWithObject:@"Alweer een Nostalgie deelnemer! #nostalgiebusje" forKey:@"InstagramCaption"];
    [self.documentInteractionController presentOpenInMenuFromRect: rect inView: self.view animated: YES ];
}

似乎UTI字符串被URL:usingDelegate:方法的SetupController覆盖。

您需要创建一个带有“ig”或“igo”扩展名的临时图像副本，然后与UTI“com.instagram.exclusivegram”共享。这应该只为DocumentInteractionController提供Instagram选项：

if (![fm fileExistsAtPath:tempDirectory])
[fm createDirectoryAtPath:tempDirectory withIntermediateDirectories:YES attributes:nil error:nil];

NSString *tempInstagramPath = [tempDirectory stringByAppendingPathComponent:@"instagramShare.igo"];
if ([fm fileExistsAtPath:tempInstagramPath])
    [fm removeItemAtPath:tempInstagramPath error:nil];

[UIImageJPEGRepresentation(imageToShare, 1.0) writeToFile:tempInstagramPath atomically:NO];

documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:tempInstagramPath]];
documentInteractionController.delegate = self;
documentInteractionController.UTI = @"com.instagram.exclusivegram";
documentInteractionController.annotation = @{@"InstagramCaption": @"My Photo Caption!"};
if (![documentInteractionController presentOpenInMenuFromRect:CGRectMake(0, 0, 0, 0) inView:self.view animated:YES])
    NSLog(@"Cannot open Document Interaction Controller for sharing with Instagram");

使用文件扩展名

igo

是正确的，并且列表中显示的应用程序数量比使用

ig

时要少得多。从我的测试（仅限iOS 9）来看，UTI对显示的列表没有影响

看起来已过时。

我也有同样的问题…请使用URL:usingDelegate:方法发布您的

设置控制器。设置
UTI
字符串后，此方法的结果将分配给
documentInteractionController
属性。
if (![fm fileExistsAtPath:tempDirectory])
[fm createDirectoryAtPath:tempDirectory withIntermediateDirectories:YES attributes:nil error:nil];

NSString *tempInstagramPath = [tempDirectory stringByAppendingPathComponent:@"instagramShare.igo"];
if ([fm fileExistsAtPath:tempInstagramPath])
    [fm removeItemAtPath:tempInstagramPath error:nil];

[UIImageJPEGRepresentation(imageToShare, 1.0) writeToFile:tempInstagramPath atomically:NO];

documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:tempInstagramPath]];
documentInteractionController.delegate = self;
documentInteractionController.UTI = @"com.instagram.exclusivegram";
documentInteractionController.annotation = @{@"InstagramCaption": @"My Photo Caption!"};
if (![documentInteractionController presentOpenInMenuFromRect:CGRectMake(0, 0, 0, 0) inView:self.view animated:YES])
    NSLog(@"Cannot open Document Interaction Controller for sharing with Instagram");
