私のクライアントは、Instagram で画像を共有したいと考えています。Instagramでの画像共有を実装しましたが、特別なハッシュタグを付けて共有することはできませんでした。これまでの私のコードは次のとおりです。
- (IBAction)sharePhotoOnInstagram:(id)sender {
UIImagePickerController *imgpicker=[[UIImagePickerController alloc] init];
imgpicker.delegate=self;
[self storeimage];
NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
{
CGRect rect = CGRectMake(0 ,0 , 612, 612);
NSString *jpgPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/15717.ig"];
NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", jpgPath]];
dic.UTI = @"com.instagram.photo";
dic.delegate = self;
dic = [self setupControllerWithURL:igImageHookFile usingDelegate:self];
dic = [UIDocumentInteractionController interactionControllerWithURL:igImageHookFile];
dic.delegate = self;
[dic presentOpenInMenuFromRect: rect inView: self.view animated: YES ];
// [[UIApplication sharedApplication] openURL:instagramURL];
}
else
{
// NSLog(@"instagramImageShare");
UIAlertView *errorToShare = [[UIAlertView alloc] initWithTitle:@"Instagram unavailable " message:@"You need to install Instagram in your device in order to share this image" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
errorToShare.tag=3010;
[errorToShare show];
}
}
- (void) storeimage
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *savedImagePath = [documentsDirectory stringByAppendingPathComponent:@"15717.ig"];
UIImage *NewImg = [self resizedImage:picTaken :CGRectMake(0, 0, 612, 612) ];
NSData *imageData = UIImagePNGRepresentation(NewImg);
[imageData writeToFile:savedImagePath atomically:NO];
}
-(UIImage*) resizedImage:(UIImage *)inImage: (CGRect) thumbRect
{
CGImageRef imageRef = [inImage CGImage];
CGImageAlphaInfo alphaInfo = CGImageGetAlphaInfo(imageRef);
// There's a wierdness with kCGImageAlphaNone and CGBitmapContextCreate
// see Supported Pixel Formats in the Quartz 2D Programming Guide
// Creating a Bitmap Graphics Context section
// only RGB 8 bit images with alpha of kCGImageAlphaNoneSkipFirst, kCGImageAlphaNoneSkipLast, kCGImageAlphaPremultipliedFirst,
// and kCGImageAlphaPremultipliedLast, with a few other oddball image kinds are supported
// The images on input here are likely to be png or jpeg files
if (alphaInfo == kCGImageAlphaNone)
alphaInfo = kCGImageAlphaNoneSkipLast;
// Build a bitmap context that's the size of the thumbRect
CGContextRef bitmap = CGBitmapContextCreate(
NULL,
thumbRect.size.width, // width
thumbRect.size.height, // height
CGImageGetBitsPerComponent(imageRef), // really needs to always be 8
4 * thumbRect.size.width, // rowbytes
CGImageGetColorSpace(imageRef),
alphaInfo
);
// Draw into the context, this scales the image
CGContextDrawImage(bitmap, thumbRect, imageRef);
// Get an image from the context and a UIImage
CGImageRef ref = CGBitmapContextCreateImage(bitmap);
UIImage* result = [UIImage imageWithCGImage:ref];
CGContextRelease(bitmap); // ok if NULL
CGImageRelease(ref);
return result;
}
- (UIDocumentInteractionController *) setupControllerWithURL: (NSURL*) fileURL usingDelegate: (id <UIDocumentInteractionControllerDelegate>) interactionDelegate
{
UIDocumentInteractionController *interactionController = [UIDocumentInteractionController interactionControllerWithURL:fileURL];
interactionController.delegate = self;
return interactionController;
}
- (void)documentInteractionControllerWillPresentOpenInMenu:(UIDocumentInteractionController *)controller
{
}
- (BOOL)documentInteractionController:(UIDocumentInteractionController *)controller canPerformAction:(SEL)action
{
// NSLog(@"5dsklfjkljas");
return YES;
}
- (BOOL)documentInteractionController:(UIDocumentInteractionController *)controller performAction:(SEL)action
{
// NSLog(@"dsfa");
return YES;
}
- (void)documentInteractionController:(UIDocumentInteractionController *)controller didEndSendingToApplication:(NSString *)application
{
// NSLog(@"fsafasd;");
}
注:これは正常に機能しています。
私はhttp://instagram.com/developer/iphone-hooks/で彼らのドキュメントをフォローしましたが、それからより良いアイデアを得ることができませんでした!. ハッシュタグやその他の情報を含む画像を共有するための次のステップを何をすべきかわかりません。
次に、特定のハッシュタグで共有されているすべての画像をアプリケーションに取得したいと考えています。
ガイドしてください!前もって感謝します!
