I have a problem with my App.
In the update I'm testing I'm modifying the DB adding a column to a table.
Everything works just fine in the simulator, but when I run the App in my iPhone, at the moment it reaches the query where the new column is, it completely skips the while(sqlite3_step(stmt) == SQLITE_ROW) and returns no rows to my tableview.
I want to check if the DB in my iPhone has been updated correctly but I don't know where to find it.
If you want to find the DB,On your device follow this steps
1.Go to organize window of your x-code.
2.There you can find a option name as device on the top bar.
3.ClIck on device your connected device has greens button side.
4.Click on your device,go to application there you can see a folder as Document.On the folder your DB reside.Download your DB and test.
Well exactly where the DB is depends on where you put it. However all app files are stored within this folder when using the simulator, so it will be somewhere in here -
~/Library/Application Support/iPhone Simulator/
You can access this by going to 'Go', then 'Go To Folder', from the menu bar in OSX

I am building an app for Mac which logs into a website based on login and password collected from textfield and secure text field, then app opens an url which is created in my app based on date range selection with use of two date picker cell calendars. Next app displays html data in webWiev (using WKWebView), converts html to string using extension NSAttributedString and then saves retrieved data as txt file. Everything works as expected as long as app is run from Xcode "play" button. Problem is if I archive this app and launch it, it will bring up an empty window without any button, calendar or textfield. There are no errors, no crash logs on organizer, nothing.
I decided to perform a little test. I build another view controller with only one button which upon clicking will show my app main view controller. After archiving this modified app and running it outside of Xcode a window shows view controller with one button which is correct. But after clicking it nothing happens. App works great if running "inside" Xcode, a pushbutton shows main ViewController correctly. Do You have any clue what can be wrong? thank You!
Edit 1. So I found a discussion on apple which mention this problem. It is associated with IB WKWebView and problem is already known since some time. Now I have to get around the problem. Apple forum link: https://forums.developer.apple.com/thread/116047
Did you embed WebKit.framework to your app?
After comment that I wrote, I founded a solution and solved with this method.
Please check it out.
I have an application that is currently named "xxxx". The app runs and works perfectly without any problems. However, I have reached a stumbling point. When I try to load the application onto my iPhone, the pictures on my picker view seemed to have disappeared for some strange reason. I've done multiple hours of debugging and everything checks out normal. I then decided I wanted to change the product name from "xxxx" to "xxxx Redo". As soon as I did that, the application loaded perfectly normal (with the pictures in the Picker View as it should be).
In conclusion, it comes to find out that there is no actual bug in the programming aspect of it. However, my question comes up as to why does it not load the correct way with the original product name but then loads the right way when the product name is changed?
The second part of my question is if anyone knows of a way to fix the original application so that way it displays correctly again with the original name?
I have tried the following:
Cleaning the app
Trashing the .app file and rebuilding
Deleting the app on the iPhone and rebuilding.
These things sometimes just happen, you can try the following extra steps:
clean build folder in XCode (press alt while clicking Product menu)
reboot the phone (poweroff/poweron)
I have seen cases where it made a difference.
I just finished my iPhone app and I want to make it Universal. I've read a few posts already but they're a bit old (2010 or so).
What I got:
Simple iPhone app, recently created (iOS 5 - Storyboard), with three screens.
My app represents a table with three cards that you can flip touching them. The user can input (on the second screen) text to be displayed on the cards.
When I created the project I checked "Universal" so I have two Storyboards. After that nothing else I did had to do with iPad (except for a line on my "contact support" email option where I used UIModalPresentationPageSheet).
What I'd like to accomplish:
Same app on the iPad: my application is so straightforward I don't have any use for split views or details. I just want the same objects and layout but with bigger and better graphics (table, cards, etc).
I like it because it'd make a great introduction-level migration.
I have no idea where to start. When I run the iPad simulator a white screen comes up and that's it.
Well this is done.
As with almost everything, this is pretty easy once you know what to do.
I'd say that for those cases like mine, where the UI doesn't change in more than sizes or (x,y) coordinates the process could be summarized like this:
Replicate every UI element on the iPad Storyboard (copy and paste will do) and adjust position and size as you see fit
Re-wire everything again. Every button, segue (you'll have to add the segue name again too), etc.
Verify within your code every place where your UI is affected (e.g. x,y coordinates), identify whether the app is running on an iPhone or iPad, and divide your code accordingly
If you have any localization on the application you'll have to update the new UI elements on the iPad Storyboard
Select the target for testing on the simulator and try it out
In order to identify in which device the app is running you can use the following:
if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
//I'm running on the iPad
} else {
//I'm running on the iPhone
}
And that's it. Again, in a simple case like mine the reuse of code is absolute (100%), the new code you'll have to add is minimum (basically IF statements where needed), and the UI elements duplication is as easy as copy and paste.
I hope this is useful to someone else and if you have recommendations to improve this they're more than welcomed.
Open the Storyboard file in finder,Copy your iPhone-Storyboard and rename it Main-iPad.storyboard
Inside xCode, right click on the storyboard -> “open as” -> “Source Code”
Search for targetRuntime="iOS.CocoaTouch"and make it targetRuntime="iOS.CocoaTouch.iPad"
Now save everything and reopen Xcode -> the iPad-Storyboard contains the same as the iPhone-file but everyting could be disarranged you have to arrange it by your self.
Finally to get the iPad format also change the code in the MainStoryboard_iPad.storyboard from: to
Then go to your "StroryBoardEx-Info.plist" file,search for "Main nib file base name (iPad)" and make it "Main-iPad.storyboard"
If you just want to reuse your iphone storyboard, just go to your project settings. In TARGETS tab Info, there are rows 'Main storyboard file base name' and 'Main storyboard file base name (iPad)'. Just edit the iPad one to have the same value as the other. In my case I had to edit it as 'Main storyboard file base name (iPad)' with value 'MainStoryboard_iPhone'.
I am learning iPhone development, and have built a simple app that has an image that changes to another image when you tap it.
If i build it to the simulator, it works fine, but if i build it to the device the images dont appear. i feel like they aren't being copied across. I have checked they have been named correctly and i have made sure i imported them to 'resources'
I dont think it is a problem with the code because i added a thing to also make text appear when the image is tapped, and this works, so a button is still there doing something, it just doesn't have an image on it.
-(IBAction)changeImage:(id)sender {
[fortuneCookieButton setImage:[UIImage imageNamed:#"Image2.jpg"] forState:UIControlStateNormal];
label.hidden = NO;
}
-(IBAction)restoreImage:(id)sender {
[fortuneCookieButton setImage:[UIImage imageNamed:#"Image1.jpg"] forState:UIControlStateNormal];
label.hidden = YES;
}
Does the case (upper/lower) of all your file names match exactly for all letters? Source code & project & Mac?
just to share with you, I had this same problem and I found out the solution: I was using lower case in the file name and upper case in code. The thing is on Simulator there was no problem because Mac file system is case-insensitive but in the iPad it didn't work because iOS file system is case sensitive. ;-)
I had this problem. Bizarrely the image had been working in the past, then just stopped appearing on the device one day.
It was a PNG.
I opened it in GIMP and saved it again. Then it went back to working again. No idea why.
Crazy.
Is it the case with only PNG images or also for JPG & other format you're having same issue. If it's only for PNG image, then it might be possible they're not being compressed. Try the following way.
Select your project target & go into its info. Here go into the build tab. In the configuration select "All Configurations" from Configuration section. Now, write "COMPRESS_PNG_FILES' in the search bar. And see the status of the check-box. IF it's unchecked, then make it checked & it will work. But if it's already checked, then there should be other reason in your project.
In the later case, I would request you to create a new dummy project & check by adding 2-3 images whether it's coming or not.
Clear caches delete the previous build and try again.
I also had same problem, and it was caused by a different reason: my project has image files with the same name! Since my app has many images, I inadvertently included images with the same name. Simulator is more tolerant and show the images just fine; however, when built on device, neither of the images of the same name were copied to the build directory. Obviously xcode is more picky for device: since all images go to the same directory, the file names must be different. When there are files with the same name, xcode refuses to copy any of them since it doesn't know which one to pick.
I have the same problem. In my case, the issues is to do with the UILabel above the UIImageView that shows the image. When I change the type of UILabel to AttributedText (In Property Inspector), my real devices cannot load the image. When I change it back to Plain, it works now. I use XCode 6.2.
on top of all suggestions - it wasn't work for me until I restarted the device
I want to make two different app icons, and programmatically switch betweem then. When the user quits the app without finishing an workflow-process, then I want to switch to an icon that will indicate that there's something undone when launching the app. Well, just theoretically, just for testing.
I think that the icon file is just a normal file as any other, so if I would just rename it programmatically and then give another icon file the name of the icon file that's named the Info.plist, then the app should show up with another icon, right? Would that be possible? Or do I have no access to that file for renaming it?
icon file stored in "application bundle" folder.
And your application has read-only rights to this folder
There is no oficial way to change/rename thees files.
You can add integer badge to youy icon
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:666]
But it is not official method.
It sounds like a good idea, and I would definitely give it a try, but I get the feeling this isn't possible.
I believe the app icons get stored in another file structure global to the iPhone. I say this because after I installed 3.0 beta 5, I saw a bug where the app icon disappeared from an app I developed. Then after installing two new apps from the app store, the new app's icon appeared on my app, and the 2nd new app's icon appeared on both new apps. Essentially the new app icons shifted to fill in for the missing app icon.
Removing and re-adding the apps, then rebooting the phone, restored the icons properly.
I don't know for a fact how the app icons are managed and stored on the phone, of course, but it would fit to say they are stored in some sort of cached list that gets rebuilt occasionally, perhaps after a reboot. That would mean even if you could change the icon from within your app, it would take more effort to see the effects on the phone.
