i am building an app for demonstration at a innovation-event. In this app, there is a map and the classic blue dot is showing where we are. Because this is just a demonstration/demo app, i need to simulate that our location changes, so the blue dot moves around.
I know this is possible if you connect the phone to xcode, but i need this function to be standalone in the app, without the requirement of a mac.
So i have searched for a long time now, how to overwrite a users location, and i can't seem to find an answer. Hope you guys can help me, i am building the app in Swift btw.
You can not set the location with public API. (Not sure about private API if you are not planing to release to Appstore, though.)
Your best option is to introduce your own blue dot and attach it as custom pin. Then move around the pin .,.

Recently, I have installed Twilight on my Android phone. Apparently is adds a color tone effect on the screen. Here are two screen shots taken from PlayStore.
Now my question is that is there a way to develop similar system display tone color set up application in iOS?
It is not possible as Apple restrict the developers to edit home screen. There are very limited features that we can access like Calendar, Gallery, etc. The above screenshot your are showing is related to Widget but there are no Widget concept in iOS.
Yes, it is certainly possible and I use an app that does this.
Have a look at https://github.com/anthonya1999/GoodNight, It's even open sourced.
However an app like this will most likely be denied from the App Store, but never the less it is possible.
Night Shift is supposed to bring something like this in iOS 9.3, though not to that extent.
I don't know of any public API that would allow an application to change that kind of parameter system-wise, though. Maybe in the Accessibility framework, but that would restrict it to app-wise, not system-wise.
In every ios app you can have a list that contains elements with subelements.
Tapping on the element will open a new page and you can usually press back to return.
This is indicated with a grey ">" symbol on the right.
Is this symbol downloadable somewhere? I know i can just type a > but it doesn't look exactly like the default icon used by ios.
I'm using Xamarin dialog and a standard RootElement embedded as a list item looks exactly like the default ios but i need to customize it with an icon placed left of the text(which is no problem except that i now lose the default > icon).
Googling for ios system icons, ios default icons and ios sdk did not yield the wanted result. I'm hoping that these icons are somewhere embedded on the device.
I hope you guys can help me out, thanks !
As far as I know there is no way to access a UIImage instance of the chevron during run time. Most likely there is private API for this, but I am not aware of it, and since it's private you are not allowed to use it anyway.
You could probably instantiate a cell that has the disclosure indicator as accessoryType and walk the view hierarchy to find it. But that will break easily, so don't do it.
The best way is to add an image and update it with every new iOS release.
There's the iOS Artwork Extractor which basically gets you every piece of artwork that is used in iOS.
The artwork you are looking for should be named UITableNext. (at least that's the name in iOS6, I don't have an extracted archive of iOS7 yet)
Strictly speaking you are violating Apples rules and their copyright if you use their artwork without Apples written consent.
As far as I know this has never been enforced, and lots of people do it, but it's good to keep it in mind.
Hi I have been working on a blackberry app and developed about 90% of the app .But my client wants the app should work on blackberry touch also. So I just wanted to know what changes I will need to do to convert the same code to work on blackberry touch .Please help me I am new to Blackberry app development .
Just to confirm, we are talking about a Java application running on BB7 or earlier OS.
The short answer is, it depends.
If you have used standard RIM controls (buttons, ObjectChoiceField etc.) then these will work on the touch screen with no change. If you have used your own controls, for example an image button, then these might not work very well - for example the button might not be big enough to be hit easily with a fat finger.
The other problem is the virtual keyboard, it may appear at points when you do not want it to and not appear when you do. Not a problem on a lot of phones, but remember there are at least 2 non keyboard phones out there, so the Virtual keyboard is the only option for typing.
The best approach is work through each of your screens and try them in the Simulator. Zoom the Simulator so that it looks like the real device. And pretend you are using a finger, don't rely on the mouse because you can position the mouse very accurately.
I would raise new questions about specific Fields that you have problems with, rather than continue this with any issues you find.
I'm trying to find out if there's a way to detect the "geotag" or "store-location" setting of the camera on an Android device. I don't mean the general location access setting which I'm very familiar with, but the more "hidden" setting when you use the camera.
Most users are not even aware it exists, and it's turned off by default, I would like to be able to tell the users that this setting is off so that they can turn it on if they want to, this way pictures will have all the EXIF data concerning their location.
I hope this has not been answered before on so, if its the case, I'm sorry about it and would you please link me to the right thread.
Each Android device usually ships with its own custom camera app, made by the manufacturer of that device. Each has their own UI and probably own way/place to store this setting, if it even exists for that device. So any answer to this question would be heavily device-dependent.
But even if you just restrict yourself to the AOSP camera app, which is the app used on the Nexus devices, there's no API for this. The app asks if you want to enable GPS tagging the first time the app is run, and after that the option to enable/disable geotagging can be found in the settings.
There's no way to confirm if that setting is on, since it's not part of any public or standard Android API. You might be able to do something with the accessibility API to read these settings, but it requires substantial permissions to do so (Accessibility service documentation here).
To extract the EXIF information from the files, you could consider an example similar to the updateExif example shown in this code snippet. This would enable you to get all the information including make, flash, focal length etc which is stored in the EXIF file.
Speaking to the Android 4.3 camera app that comes with Nexus devices, you can view and change the setting like this:
Open the camera app.
The white circle (rightmost of three icons at bottom of app screen) is used to bring up the main menu. If "store location" is turned off, that circular icon will be displayed with a small location icon with a line through it. If "store location" is turned on, there is no positive indication thereof. Tap it to continue if you want to change the setting.
Tap the settings icon (middle icon of five) to bring up "More Options" menu.
The "store location" icon is the leftmost of five. Tapping that icon toggles the setting (and dismisses the menu). If "store location" is off, that icon is displayed with a line through it, else without.
I am implementing camera application using then example comes with blackberry plugin for eclipse named "CameraDemo" the problem is that when the screen loses focus It does not display the camera view istead of it shows like this
has anybody faced such problem whats the solution?
This way of taking picture (using the Player and VideoControl.getSnapshot()) does not work nice on all BB models. I'd even say it works nice only on a narrow set of BB models. So if you are going to use your app on a wide range of BB models, then this is not the right way to go.
Instead to take a picture use a built-in Camera app. Here is a starting point on how to do that.
Basically you invoke the built-in Camera app and listen for the file-system changes to detect a new image file path. Then you need to close the built-in Camera app somehow - it's possible to do that by simulating two 'Esc' button presses.
Yes, this sounds a bit hacky/over-complicated, but that's how BB engeneers arranged that for us. :) BTW, this is actually not so bad if compare with Android where different device manufactorers violate the common rules and implement the Camera app in their specific way so you are not able to write the code once covering all Androids.
