    1) I want to have a native sign up process for my mobile app. 2) Some links in the mobile app goes to the web page of my website. But since my website requires login, and the login expires after a day, the link stops working after a day. I would like the mobile app checks whether the web browser session expires or not. If it expires, relogin for the web browser session. I know it requires server side change. Whatever changes will be, I can do it.

    Hi All,We"re searching for an expert/honest/committed to help us fix our iPhone app. The current developers failed to deliver and refusing to help. They tried to fix it and unfortunately they caused more damages ...- Name of the App: marazeem (please download the app from Apple Store)- Source Code: We"ll share the link with interested qualified developers since we don"t want to live through the failure again and again- Please refer to the below for the current problem (& also the attached images). - We also need someone to test the codes again, since no one trust the previous developers (they caused many damages; took them more three months; and provided us with more than 28 failed demos; then the final version which is published in Apple Store)The Problem:User1: Posts an item for saleUser2: click on more then send private message to user1- Hi- I"d like to buy the item- Please send me more details User1: receives a notifications that user2 sent a message; but when he goes to Icon.5, the chatting icon, he sees nothing .. a blank page.then it works if user1 replies ..User1: - Hi - did you you have any questionuser2: receives the message & they can chatBut:The first time messages are gone; they"re in the admin page but NOT in the user appMeansThe first time user2" messages don"t appear in the chat room Regards & I hope that I"m not confusing you

    HiI have built an iPhone app that"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"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"t working such as some labels aren"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.

    We have an already built one-screen application that we need to have modified a bit. The application works as follows:-When a user opens the app, it shows a list of near places to the current location using FourSquare API.-At the bottom of the main screen there are 5 buttons, 4 of them are to categorize the places, as in the "Restaurants" button would filter the list to show only restaurants and so on. The fifth button "Placed in the middle" shows a timer.-When a user clicks on a name of a place, a pop up appears and it shows: oA graph of a smiley face, we want to change the graph. oThe name of the place on the top bar of the popup o The amount of time it"ll take to go to that place "using Google API" o The address of the place. (We need this to be removed) oA button named "Directions" to open Google maps or Apple maps navigation.-The main screen has a search box, when a user types a text the app searches for the places using the FourSquare API. We have an issue with this function and that it doesn"t support searching in Arabic letters.-After a user clicks on the "Directions" button, a timer should start, and send notifications for the user even if the user is opening Google Maps or Apple Maps to navigate. This has been done, but we need the notifications to be timed, as in it should be triggered ten minutes, and five minutes before a specific time.Requirements:-Change the icon of one of the bottom menu buttons.-Change the text of the "Timer" button in the bottom menu should be changed for a few seconds when clicked then change back to show the time.-Fix the Arabic search issue.-In the pop up, change the "Directions" button"s color.-In the pop up, remove the address label.-In the pop up, replace the smiley faces with new icons.-Only trigger the timed notifications ten, and five minutes before the specified time. And they should only be trigged after the user goes to navigation "opens Google Maps, Apple Maps".-The developer has to be familiar with the FourSquare and Google APIs.-The developer has to use testflight for us to test the application as it"s being built.-The deadline is 1-2 days.-Price is 50$.

    Very simple request and straight forward code writing only.I have an app that is based on UILocalNotifications. These local notifications are fired every five minutes on hourly repeat intervals. So far, I have 24 notifications. All I want is to add a (Sleep Mode) function. Very similar to IOS Do not disturb. it should allow the user to select a sleep time and wake up time through two Date Pickers. I have set up these date pickers and got stuck on how to ignore or cancel these notifications through the period that user had specified and reschedule them again automatically while the app is in the background.If you have the ability, experience and knowledge to add such a function to an existing project, please let me know how long it would take you to do so and how much would it cost me?. Thank you.

    I have a simple design that I want to make into an iPhone Application for others the download. It"s a market update on prices for gold, silver, etc.Few things to keep in mind:1) When the price is up it will show a red bar, and a red negative with the current price.2) When the price is up it will show a green bar, and a green positive with the current price.3) It needs to display the last time it was updated below with the key.4) YOU NEED TO FIND a API to work with for this. It needs to be an USD but away for the user to change the pricing into different currency.5) At the bottom it shows an ad, , I don"t want that there anymore, I will have a text on it. I just want a giant pop up using admob.6) I want it so there is a way to go ad-free (no ads displaying for a price)7) I want it to work on 5c and 5s/ and 4 series with easy access to updating the project.8) The stuff showing right now is what will always show.9) A pop up to get reviews.

  • $200 USD 19 days ago

    We have an iPad application on iTunes already. Here is the link for it

For the new version of this app, we are adding new screens to it. New screens are very similar to the existing screens, layout and functionality wise. So there is plenty of sample code in the project.App has 2 main layers. UI layer and data API layer which talks to a server for data transfers back and forth. It"s a pretty clean data API to integrate with UI. So you won"t be doing any data integration with the actual server, you"d just do regular objective-c calls to a data class to read or write data. Design mentality will have to be kept throughout the app with the new screens

For this specific task we are going to add a section for managing assignments of a teacher. It will have 3 subsections in a single page.

Courses Lists
For each course, a list of assignments
Create/Delete/Update single assignments
(If this phase is completed successfully, we will do grading of these assignments on the same screen for the students taking the course)

Screen will be similar to the "Courses" section in the app. A list of courses on the top left corner, a list under it for the assignments. And a grading section for students on the right side covering all the height of the screen.

 Data APIs for these data are ready. You will only do 
Main view with tables laid out in itSelection in one table reloads data in the other tableAnother view for managing a single assignment (a form of around 13 fields). This view pops up when clicked on + or edit icons on the assignments table.if you get the job we will do an initial walk through of the existing code to get you familiar with the process

.We require very clean and precise work, as you will see in the existing code. 
you will also gain good experience and best practices.There is a lot more screens to be added for this phase. If we like the work you do, there will be more tasks ahead.
