I'm looking for solution of problem that I get image from my server and that image will be only be one(not for compatible all devices) and that image will also use in android device too so as you know android support SVG but iOS isn't (that 1 image should be use on all iOS devices even on iPad too). I look into this Tutorial and this use from PDF and also use local pdf.
So what will be approach from iOS end or server end to download 1 image (with one size) and will be show on all devices.
Looking for suggestions and help to resolve this issue.
You can try to implement PocketSVG (https://github.com/pocketsvg/PocketSVG) to do that.
There is one downfall though: it only supports SVG features that can be drawn using CGPaths or UIPaths.
I want to check if the 3x assets I have are in the correct resolution. I don't have my knowledge with Objective-C or Swift, so is there a way to check without using Xcode?
I have very basic knowledge of Swift and Xcode (navigating and such) so if someone can give me the steps I think I can do it.
I want to check this because I have a low resolution file with maximum output of 2x, so I'm trying find a way to get the 3x without losing quality by migrating the PSD file to AI.
I am developing a Phonegap application for IOS and I want to use Capture plugin for it. I have installed the plugin using CLI and added permissions in the config.xml file but the plugin os not working it do not show any output or error.
Basically the problem I have is with the image orientation when image captured from the camera. The image rotates in landscape direction.
I have tried to read the exif data in PHP but IOS trims the exif data from image before sending it to the server
I have installed the capture plugin but it is not working on IOS 7.1
I just need to make the orientation of the image right when taken from the camera.
Within the .getPicture() call you can set the option
correctOrientation: true
This solved my problem of portrait images turning horizontal however on my LG G2 significant lag was added during the capture process when this flag was set. I'm still trying to figure out a server-side fix but with some EXIF data being stripped it's a bit challenging.
Docs explain a little more:
http://plugins.cordova.io/#/package/org.apache.cordova.camera
correctOrientation: Rotate the image to correct for the orientation of the device during capture. (Boolean)
I'm currently using AVCaptureSessionpresetPhoto to take my pictures and I'm adding filters to them. Problem is that the resolution is so big that I have memory warnings ringing all over the place. The picture is simply way to large to process. It crashes my app every single time. Is there anyway I can specify the resolution to shoot at?
EDIT**
Photography apps like Instagram or the Facebook Camera app for example can do this without any problems. These applications can take pictures at high resolutions, scale them down and process them without any delay. I did a comparison check, the native iOS camera maintains a much higher quality resolution when compared to pictures taken by other applications. The extreme level of quality isn't really needed required for a mobile platform so it seems as if these images are being taken at lower resolution to allow for faster processing and quick upload times. Thus there must be a way to shoot at a lower resolution. If anyone has a solution to this problem, it would greatly be appreciated!
You need to re-size image after capture image using AVCaptureSession and store it's image after resizing.
You found lots of similar question in to StackOverlow i just putting some link bellow that makes help's you.

Using UIImageView I am trying to animate an image sequence of 300 PNG files, it works fine on the simulator however on actual device this doesn't work at all and what i see is a blank sereen.
If I am right then this is possibly due to the large number of images (300 approx.) that I am trying to load and animate or is there any other issue. Please advise?
It will depend on how big the .png files are, which test device you're using etc. When you test on the simulator it has access to all the computers RAM, which is considerably more than an iPhone does. I'll try to improve my answer if you post up some code. It sounds like there is a better way to do it.
Have you tried using a small subsection of the frames (say 10) and see if that works? You could also profile your app and check whats going on that way?
