私は最近、次の興味深い機能に出くわしました: Instagram iPhone Hooks
プレビュー (– presentPreviewAnimated:) またはアクション シート (– presentOpenInMenuFromRect:inView:animated:) を表示することなく、 documentinteractioncontroller を介してアプリをすぐに開くことができるかどうか疑問に思っていました。それが唯一の方法のように思えますが、何かが欠けている可能性があります。
-(void) saveToInstagram {
NSURL *url;
UIDocumentInteractionController *dic;
CGRect rect = CGRectMake(0 ,0 , 0, 0);
UIImage *i = imageView.image;
CGRect cropRect = CGRectMake(i.size.width - 306 ,i.size.height - 306 , 612, 612);
NSString *jpgPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/Test.ig"];
CGImageRef imageRef = CGImageCreateWithImageInRect([imageView.image CGImage], cropRect);
UIImage *img = [[UIImage alloc] initWithCGImage:imageRef];
CGImageRelease(imageRef);
[UIImageJPEGRepresentation(img, 1.0) writeToFile:jpgPath atomically:YES];
url = [[NSURL alloc] initFileURLWithPath:jpgPath];
dic = [self setupControllerWithURL:url usingDelegate:self];
[dic presentOpenInMenuFromRect:rect inView:self.view animated:YES];
[dic retain];
[img release];
[url release];
}
- (UIDocumentInteractionController *) setupControllerWithURL: (NSURL*) fileURL usingDelegate: (id <UIDocumentInteractionControllerDelegate>) interactionDelegate {
UIDocumentInteractionController *interactionController = [UIDocumentInteractionController interactionControllerWithURL: fileURL];
interactionController.delegate = interactionDelegate;
return interactionController;
}
- (void)documentInteractionControllerWillPresentOpenInMenu:(UIDocumentInteractionController *)controller {
}
