Instagram 可以在 Android 和 iOS 中实现吗？

Question

我们正在制作一个基于地图的 Android 应用程序，并且我们会在地图上的标记上弹出一个带有信息的窗口。我们集成了一个 Facebook 图标，该图标仅链接到标记的 Facebook 页面。

构建我们应用程序的公司告诉我们，由于 Instagram 尚未发布“SDK/API”，Instagram 目前无法实施？

这是真的吗，或者我们可以将“Instagram”图标从地图上的标记集成到我们的弹出信息框，以链接到所需的页面？

谁能帮忙？

我正在instagram 上共享图像，实现以下代码。请遵循此代码，我认为这将帮助您进行iOS 开发。

在你的 .h file 添加一个 Delegate Method 。" UIDocumentInteractionControllerDelegate "

并声明UIDocumentInteractionController *docController;

在您要在 Instagram 上分享图片的.m File 中，在单击instagram 按钮操作时编写此代码。

-(void)instagramshare_action
{     
    NSURL *instagramURL = [NSURL URLWithString:@"instagram://location?id=1"];

            if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
            {
                NSFileManager *fileManager = [NSFileManager defaultManager] ;
                NSArray *path=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
                NSString *imagePath=[path objectAtIndex:0];
                imagePath =[imagePath stringByAppendingPathComponent:@"ResizeImage"];
                NSArray *temp=[fileManager contentsOfDirectoryAtPath:imagePath error:nil];
                NSString *tempImgPath = [imagePath stringByAppendingPathComponent:[temp objectAtIndex:0]];
                NSData *imgData = [NSData dataWithContentsOfFile:tempImgPath];
                UIImage *img = [UIImage imageWithData:imgData];

                CGRect rect = CGRectMake(0,0 ,612,612);
                [img drawInRect:rect];
                CGRect cropRect5 = CGRectMake(0,0,612,612);
                UIGraphicsBeginImageContextWithOptions(cropRect5.size,2.0,1.0);
                [img drawInRect:cropRect5];
                UIImage * customScreenShot = UIGraphicsGetImageFromCurrentImageContext();
                NSLog(@" custom sc==%@",customScreenShot);
                UIGraphicsEndImageContext();

                //saving to document directory
                NSArray *paths10 = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
                NSString *documentsDirectory10 = [paths10 objectAtIndex:0];
                NSString *ImageName10 = [NSString stringWithFormat:@"image.png"];

                NSString* appFile = [documentsDirectory10 stringByAppendingPathComponent:ImageName10];
                NSLog(@"appFile==%@",appFile);
                NSData*  myImageAsData = [NSData dataWithData:UIImagePNGRepresentation(customScreenShot)];
                [myImageAsData writeToFile:appFile atomically:YES];

                //getting image(png format) from document directory and again saving with ig format
                NSString *ImageName1 =@"image.png";
                NSString *getImagePath =[documentsDirectory10 stringByAppendingPathComponent:ImageName1];

                UIImage *img1 = [UIImage imageWithContentsOfFile:getImagePath];

                NSData *data = UIImageJPEGRepresentation(img1, 1.0);
                UIImage *images = [[UIImage alloc] initWithData:data];

                NSLog(@"img==%@",images);
                CGRect rect2 = CGRectMake(0,0,612,612);

                [img1 drawInRect:rect2];

                NSString *ImageName = [NSString stringWithFormat:@"Image.ig"];

                NSString* appFile2 = [documentsDirectory10 stringByAppendingPathComponent:ImageName];
                NSLog(@"appFile==%@",appFile2);
                NSData*  myImageAsData2 = [NSData dataWithData:UIImagePNGRepresentation(img1)];
                NSLog(@"myimagedata==%@",myImageAsData2);
                NSURL *imageUrl = [NSURL fileURLWithPath:appFile2];
                [myImageAsData2 writeToFile:appFile2 atomically:YES];
                docController = [[UIDocumentInteractionController alloc] init];
                docController.delegate = self;
                [docController retain];
                docController.UTI = @"com.instagram.photo";
                [docController setURL:imageUrl];
                CGRect rect4=CGRectMake(0,0,320,480);
                [docController presentOpenInMenuFromRect:rect4 inView:self.view animated:YES];
            }
            else
            {
                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 show];
                [errorToShare release];
            }
}


Important : You have to install Instagram App on your device otherwise i write the code for showing alert. And for checking with `instagram` you have to create a account on `instagram`

我认为这会对您有所帮助，为 instagram 实现 iOS 。 :)
