Core data setReturnsDistinctResult not working

阅读更多关于 Core data setReturnsDistinctResult not working

问题 So i'm building a small application, it uses core data database of ~25mb size with 4 entities. It's for bus timetables. In one table named "Stop" there are ~1300 entries of bus stops with atributes "name", "id", "longitude", "latitude" and couple relationships. Now there are many stops with identical name attribute but different coordinates and id. So I want to show all distinct stop names in table view, i'm using setReturnsDistinctResults with NSDictionaryResultType and setPropertiesToFetch.

iPhone Simulator: SpringBoard failed to launch application with error: 7

阅读更多关于 iPhone Simulator: SpringBoard failed to launch application with error: 7

Building an iPhone project results in: Failed to launch simulated application: SpringBoard failed to launch application with error: 7 And the app doesn't install on the simulator. What's this all about? What's SpringBoard and what is error 7? I had the exact same problem - I reset the iphone simulator and then quit the simulator (i.e. command q) then started it again. Worked. Boy, is the answer to this one hard to find, but I came up with a workaround. The simulator gives this error if it has any problems with accessing files in ~/Library/Application Support/iPhone Simulator/. This could be a

阅读更多关于 iPhone In App Purchase - response.products are still empty?

Basically, I've tried to set up in app purchases on a test app before I implement them into a proper app that my company is working on. I've read the Store kit pdf and other snippets about a 1000 times, but the products are still being returned as empty. Here's exactly what I've done so far: Setup test app and In App Purchase test items I created a new app id for 'Test App One' on my company's developer portal in the iPhone Dev Centre. I made sure that the prefix was com.mycompany.testappone to ensure that in app purchases could be configured. Staying in the App IDs section, I configured in

阅读更多关于 Is it possible to connect iphone to printer via bluetooth?

问题 I want to connect iphone to a printer via bluetooth, but I don't find any class about bluetooth in iPhone 3.0 SDK. Do I need to join "Made for iPod and Works with iPhone Licensing Program" to get the SDK? Or is it possible to do this without joining the program? 回答1: Even if you join the MFi/WWi developer program, it's impossible to connect your iPhone to an arbitrary printer. The printer would need to built specifically for iPhone compatibility and incorporate an Apple-specific chip. The

阅读更多关于 iPhone/iPad data usage tracking

问题 Just wanted to ask the community a quick question. Out of curiosity, would anyone have an idea how the iPhone App "DataMan" and "Data Usage" are pulling data readings of your personal cellular data usage? I've check the web high and low for possible answers and all so far has been dead ends. How could they have gotten their Apps to be Apple approved? Any help or advice would be great! 回答1: One way to do this would be to install a configuration profile with the proper APN settings which will

How do you prompt the user to rate your iphone app without waiting for them to delete the app?

阅读更多关于 How do you prompt the user to rate your iphone app without waiting for them to delete the app?

I am referring to the popup window that asks the user to submit a review/rating. I know it can be done since the Aardark app does it...it asks several times in fact! (Almost too spammy.) But there has to be an API to trigger the rating request? Google is giving me no love on this one. I would check out the Appirater project that Arash Payan has put together. Pretty much handles the checking and displaying of the "rate my app" prompt, and brings the user right into the review portion of your app on the App Store. It's a very clean, and elegant way to provide that minimum barrier so that your
