I'm developing app using MonoTouch. In debug|simulator everything looks fine, But when i use debug|iphone images are not displaying.
But when i create test app using (Tabbed Application) template, image are displaying fine.
I have set the build action to "Content" for all images. Am i missing something else?
As far as I know, MacOS uses a non-case-sensitive Filesystem and iOS an case-sensitive one. So be sure to have no typos in your filename-references etc
//Just added this as an answer, so you can "accept" it :)
Its probably a permissions issue on the files, right click one of the files in
Finder > Get Info, then under Sharing and Permissions make sure everyone has Read Only. I'm betting its currently set to "No Access".
I've seen this a lot when importing files from a Network location.

In Mac OS it is possible to attach files to a calender event and read that files on the iOS calender.
Question: Is it possible to attach a file to an iOS calender event using the Event Kit framework?
I could not find any hint in the Event Kit documentation
The short answer to your question is no - there is no way to attach a file to an iOS Calendar Event.
Why? Because there is no place to put a file. Looking at the EKEvent Class Reference turns up a short list of properties, none of which would work for our goal of adding a file to the event.
If we go up to the super class EKCalendarItem there are also no place to put a file.
However, what is it you are trying to do exactly?
If you want to attach a file on one device, say a photo of a cat, and then have that photo sync with the event to another device, you are out of luck. The documentation shows no place you could attach a binary blob to a calendar event.
However there are some other tricks you might want to try if you are ok only making it look like a file is attached:
EKCalendarItem has a notes property that stores an NSString. You could try something hacky like putting the file as binary data in a string format in there, but I wouldn't as thats silly and could break in all sorts of ways. If you are trying to just store plain text, though, that could work well.
If you want to link to the file using a URL you can put the URL in the notes property as another comment suggests, but I would suggest you use a different property - the URL property.
As for how you can give the impression there is a file attached to a calendar event (without actually being able to) I would suggest you look into the magic a good URL scheme can provide. I'm not sure what functionality you are looking for, but a URL scheme is an Apple approved way to tell your software to show a 'file' (Well, a view in your app that could be a file) by clicking a URL attached to a Calendar Event. You will still have to take care of getting the file onto the device, but that should get you closer to what you want. Good luck!
No, EventKit does not allow you to add an attachment to an EKEvent.
The only idea I can offer is to use the notes attribute to keep the file's url.
You can add an attachment like a photo in the OS X iCal application. When synced to you iPhone it will be visible in the iOS Calendar App.
Save it to Dropbox, copy the link and paste it to the URL box in Calendar Event. It's kind of wonky but it does work. Maybe Apple would do well to creat the functionality to link to photos, docs etc. It should be pretty straight forward.
I don't know if this was untrue at the time this was asked, but now... you certainly CAN add an attachment such as an image. AND...there are actually SEVERAL file types you can add!!
I wanted to add my mobile concert ticket & barcode image to the my iCal event so everything for the night would be consolidated.
Albeit this is more sort of a work around, because it's not done directly in your iOS iCal, but it's very much possible to do. (and all from your iOS device) You simply go about doing it through your iCloud within a browser.
TO ADD AN ATTACHMENT TO iCAL EVENT:
Open icloud.com in and enter your Apple ID and PW.
Double-click the event to open it (if it isn't open already).
Do any of the following: Click Add File next to “attachments,” locate the file on your computer, then click Choose. Drag the file into your event. ...
Click OK. A paper clip icon appears on the event to indicate there's an attachment.

It is possible attaching files to your calendar entries! There is a little application for iPhone and iPad you can use (secretary-app.de).
I have been struggling (see here & here) for a while now to get it right to write to my app's documents directory. It always tell me "Not a Directory" even though the code is just copied from a simple tutorial etc.
Do I need to set anything in the Target or project settings to be able to accomplish this?
My code works totally fine on the simulator, but not on the actual device.
Usually it works like a charm to write on the documents directory. No need to setup anything on the project level. The only difference I see regarding the file system is that it is case sensitive on the device and case insensitive on the simulator. Say you want to write in a folder called "Document", if you spell it "document" in your code it is going to work in the simulator (just like it would work if you spelled it "doCumEnt"), but it won't work on the device.
The answer is NO
The problem got solved by setting a non standard Bundle ID in die info.plist
I used the Bundle ID from iTunes Connect for this specific app. Now everything works perfectly.
Im new to iPhone programming and wanted to see how people have solved this problem:
Ive created my app which will ship with certain pLists and .png files in the main bundle. However, what I want to do is when the app starts up, Id like it to check my server to see if there are updated versions of the files in the documents folder available. If so Id like the app to download those files.
I was wondering if someone can point me to some resources on how to do this? Ive searched online but haven't come up with good hits.
Whats the google key-word for searching this topic anyways?
Thanks a lot
you can use NSUrlRequest to download the files, to move them to the correct place you can use NSFileManager, if you look at the apple docs for both these classes there should be sample code explaining how to copy/save a file from NSData, and also how to download it.
I don't have any example resources of how to do exactly this, though I would probably do something along the lines of onAppLoad checking to see if the content of the application that you want to keep updated is the most recent, and if not, download it.
As for keywords to search I would try something along the lines of "Automatic App Content Updating/Verification" and throw in "iOS/iPhone/iPad" or some similar combination.
I'll do some more poking around and shoot you a comment notification if I find anything worthwhile, and then edit my post with it.
I want to bind my app to some file extension so when I receive an email with an attached file with the correct extension, clicking on it will launch my app and pass it the attached file.
Is it possible ? How ?
Thx

As iPhone applications are not allowed to share files on the file system, what you're looking for is not immediately possible (not with the published APIs that I know of, anyway). You might still have a couple of options though.
Either way you'll have to use a custom URL scheme, which is associated with your app, and paste that into your email. This URL might point to some external location, which your app can download the file from.
Or it might contain the actual file contents if it's fairly small. URLs are 'just text' (some restrictions apply), so you're free to put any data you want to in it, as long as it is URL-encoded.
You still need to get the URL into the email though, which might or might not be as easy as attaching a file.
It's not possible to simply associate a file extension with an application on the iPhone.
You could create a custom URL scheme that would launch your app, but probably that won't help you.
This is actually possible, I'm working on this exact same problem and this great tutorial has really helped me.
I was wondering if I could add the files to the app resources from an external url. As in suppose I see a url which has a nice image. Can I download that from the website and add it as a resource and use it locally for later use ? I am sure there is way But Need some guidance on how to approach the problem and The set of Classes that could be used with explanantion.
Thanks,
You can't change anything in your app bundle after it has been signed. If you did, you'd make the signature invalid, and the iPhone would refuse to run your app. Your best bet is to add the files to the Documents or tmp folder. There really isn't much of a reason to have stuff in your own bundle - is there a reason you have to have those images there?
