Transloadit iPhone SDK

The transloadit iPhone SDK contains a sample iPhone project along with a TransloaditRequest class that you can use in your own project.

Getting started

The first thing you should do is edit the Config.m file that comes with the project. You will need a transloadit account, as well as a template id.

Once you have set this up, you can start the app and test some file uploads.

Using Transloadit in your own app

In order to use transloadit in your own app, you need to add the following files to your project:

• Classes/Transloadit/TransloaditRequest.h
• Classes/Transloadit/TransloaditRequest.m

The TransloaditRequest class depends on two additional libraries that you need to install separately:

• json-framework (New BSD License)
• ASIHttpRequest (BSD License)

Examples

Assuming you have a UIImagePickerController callback, you can upload the selected file like this:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
	TransloaditRequest *transload = [[TransloaditRequest alloc] initWithCredentials:@"your-key" secret:@"your-secret"];
	[transload setTemplateId:@"your-template-id"];
	[transload addPickedFile:info];
	[transload setNumberOfTimesToRetryOnTimeout:5];
	[transload setDelegate:self];
	[transload setUploadProgressDelegate:self];
	[transload startAsynchronous];
}

- (void)setProgress:(float)currentProgress
{
	NSLog(@"upload progress: %f", currentProgress);
}

- (void)requestFinished:(TransloaditRequest *)transload
{
	NSString *assemblyId = [[transload response] objectForKey:@"assembly_id"];
	NSLog(@"assembly id: %@", assemblyId);
	[transload release];
}

If you need to pass dynamic params instead of just a template id, you can tweak the example from above like this:

// [transload setTemplateId:@"your-template-id"];
NSMutableDictionary *steps = [[NSMutableDictionary alloc] init];
NSMutableDictionary *resizeStep = [[NSMutableDictionary alloc] init];
[resizeStep setObject:@"/image/resize" forKey:@"robot"];
[resizeStep setObject:[NSNumber numberWithInt:100] forKey:@"width"];
[resizeStep setObject:[NSNumber numberWithInt:100] forKey:@"height"];
[steps setObject:resizeStep forKey:@"resize"];
[[transload params] setObject:steps forKey:@"steps"];

TransloaditRequest API

@property(nonatomic, retain) NSMutableDictionary *params;

The params field with the instructions that will be send to transloadit.

@property(nonatomic, retain) NSDictionary *response;

The parsed response from transloadit.

- (id)initWithCredentials:(NSString *)key secret:(NSString *)secret;

Initializes a transloadit request with the given key and secret.

- (void)addPickedFile:(NSDictionary *)info;

Takes a picked file and prepares it for uploading. This can either be a video or an image.

- (void)addPickedFile:(NSDictionary *)info forField:(NSString *)field;

Same as the above, but you can specify the form field name to be used for this upload.

- (void)setTemplateId:(NSString *)templateId;

Sets the TransloaditRequest.params.template_id property.

- (bool)hadError;

Returns true if transloadit returned an error code.
