MGInstagram

MGInstagram is a iOS Utility for posting Images to Instagram from your app.

The Process

  • An "openInMenu" is displayed when attempting to post a picture. (Currently the only way to post to instagram)
  • The user will have a choice to cancel or to select Instagram
  • If the user selects Instagram, the user will be taken to the Instagram app with their Image.

Setup

CocoaPods is recommended.

CocoaPods

  • Add pod 'MGInstagram', 'X.X.X' in your Podfile. Fill in X.X.X with the latest pod spec version or :head if you live dangerously.
  • import #import <MGInstagram/MGInstagram.h> Into your desired file.

Manual

  • Drag and drop the MGInstagram Folder into your iOS project
  • import #import "MGInstagram.h" into the file you plan on using MGInstagram

MGInstagram Available Methods

//Create an instance
self.instagram = [[MGInstagram alloc] init];

//Set the photo file name
//The following will present various options including Instagram
self.instagram.photoFileName = @"TempPhoto.png";
//The following will only show Instagram as an option
self.instagram.photoFileName = kInstagramOnlyPhotoFileName;

//Checks to see user has the instagram app installed
//Returns YES if user does have the app
[MGInstagram isAppInstalled];

//Post UIImage to Instagram
//Presents an "openInMenu" model in the UIView specified  
//User is only given Instagram as an option
[self.instagram postImage:image inView:self.view];

//You can also post with a caption!
[self.instagram postImage:image withCaption:@"This is an #MGInstagram Caption Test" inView:self.view];

//Checks if the UIImage is at least 612x612 pixels.
//Instagram upscales photos below this resolution, so it is
//recommended to ONLY allow for photos above 612x612 to ensure good quality.
//However, this is your choice whether or not to check.
//Returns YES if correct size
[MGInstagram isImageCorrectSize:image];

Example Usage

UIImage *image = [UIImage imageNamed:@"MyImageName.png"];
if ([MGInstagram isAppInstalled] && [MGInstagram isImageCorrectSize:image]) {
    [self.instagram postImage:image inView:self.view];
}
else {
   	NSLog(@"Error Instagram is either not installed or image is incorrect size");
}
