    Hi I am after a very simple mobile app to be made in Cocos2d-x. Experience with this API is a must, and responders must show previous Cocos2d-x work as a sample. This app is intended to be released immediately on the iPad (mini and retina), and Android as a later project.The app will be for an interactive book series, with simple tweening actions of images / panels. Touch interaction will be used to progress panel animation, page turning, and in-panel effects. All artwork, sound and music will be supplied (including retina images as well as normal dpi). The app will have support for In-App Purchasing to unlock future series books / episodes.The requirements are very simple and listed below;- The app will have 4 screens (Title Screen, Settings, Episodes, Episode 1).- The app will be written to parse a .plist XML file which describes in text form the animations of each panel on each page of the episode.- All Cocos2d-x Actions need to be supported in the .plist parser (move, rotate, scale, easing operations etc)- In the files section are sample screen mockups and a sample .plist XML file which describes a dummy book with 4 pages consisting of 2 panels per page.- The project needs to deliver workable source code for the iOS simulator in the latest Xcode (at the time of writing is 4.6.3).If you have any questions to assist in your bid, please dont hesitate to contact myself. Thank you for your interest.

    HiI have built an iPhone app that&quot;s been on the app store for over 4 years now. I have a minor update I want to release and it fully works in Xcode 4. However I can&quot;t submit it to the app store as it needs to be compiled in Xcode 5. It does compile, I managed to do some fixes like getting the status bar working, however there are more things that aren&quot;t working such as some labels aren&quot;t getting set, table row colours are different, and the animations moving from table grids to sheets are not smooth.I just need someone to take my fully working Xcode 4 app and make some tweaks to make it work in Xcode 5.

    I&quot;m looking to have an app that places a working clock on the lock screen of the iphone. I want it to look like and work like the face of a watch. So when I want to check the time I can take out my phone, hit the button and the watch will appear and show me what time it is. Is this possible to do? If so, is it a difficult project.

    This app is about morphing the facial features from two photos. The app will have a library of faces and the user could either take a photo of themselves, choose one from their own library, or start with a app face, then swap the features of the starting photo with the facial features available in the app eg eyes, nose, mouth, face shape and hair. When a user adds a facial feature to their photo I would like the skin tone to blend with the user&quot;s photo. Also I would like the user to be able to resize the feature that they are adding to their picture, so say for example it is a nose that they are adding, I want them to be able to adjust the height and width if the nose so that it completely fits their face. Then the user can save their photo to a gallery on the app or on their phone, message the picture, as well as share their photo on Facebook, Twitter and Instagram, but when they do I want the name of the app to appear across the bottom of the picture. I would like you to take care of the design of this app, it&quot;s important that it looks really professional and pretty. When the user purchases the app I want them to get 20 faces to use and then i want them to receive a pop up request to leave a 5 star rating to unlock 5 extra faces. I would like this pop up to appear each time they open the app if they haven&quot;t left a review.
