I'm using Qt5.5 for iOS development.
I'm wondering how to find and open a file in an iOS device to read and write using Qt5.5. As I know, there's no such file tree structure in iOS. When I download a picture, for example, I even do not know where it locates. But I can see it in apps.
Is there anyone can help? Thanks very much.
I am no expert with Qt, but I believe you need the QStandardPaths class.
iOS is no different to any other platform that stores files in certain pre-defined locations.

I want to implement FileMQ for file transfer from iOS to android in my iOS app.
I tried the steps given here but it causes errors at many steps. Also I need to know how should I use the downloaded library.
How should I compile FileMQ for iOS and use it?
Any information in this regard is appreciated!
I downloaded a C version of the library from the link mentioned in the question and compiled it on linux machine. I made some changes in the headers to make it iOS compatible as the headers were generated for linux. Now I am using the same copy in my iOS project.
I was trying to get the header files from the ToneKit framework on iOS7.1, but I found that I cannot use class-dump because there are no executable files inside the framework. From what I have found after some research, it seems as if the actual executable file is inside the dyld_shared_cache on the device. After reading this article, it seems as if there are some tools to decrypt the cache, but since iOS 3, Apple has implemented ASLR which has made the decryption tools not work. How can I extract the Frameworks from inside the dyld_shared_cache on iOS7.1?
I am very new to jailbroken ios development so please bear with me.
If you're interested in how they got those headers then the answer is very simple - iOS SDK. SDK contains ARM binaries of public and private frameworks because they are required to compile iOS applications. Class-dump them and you will get headers you need. ToneKit.framework binary is also in there.
Usually you don't need dyld_shared_cache, almost everything you need is either in iOS SDK or on a device itself like SpringBoard, other system applications etc.
Of course there are rare cases when dyld_shared_cache is the only place you can find certain binaries as they are missing from both iOS SDK and device. In that case I use IDA. It has free demo version that can open dyld_shared_cache files - you can even open individual binaries inside it rather than dump everything. You just need to copy dyld_shared_cache on your PC.
I think Elias Limneos's classdump-dyld can help you. If not, check out RuntimeBrowser. Failing that, even, weak-classdump has proven to be a very useful runtime tool for me.
I am building an ios application in which I get a ply file from a server and want to view
it on my application using kiwi viewer , I need a help on how to do that exactly and where
can I download the related files.
I have searched the web on it but did not get anything specific on the way of doing that and I got confused with files that should be attached to my project and the libraries also.
please I need help as soon as possible.
thanks in advance
#flashdisk what version of ves / kiwi viewer you are using? The current version of VES can load the ply files. I am about to merge another branch that intend to fix some other issues as well.
I have been given a Shared Object file (.so) and the functions inside of it, but I don't have a clue as to how to use it, or alter it for use in an iOS application. Could someone point me in the right direction?
I know the .so came from an Android application, but I was told I could get it to work in an iOS application as well.
Actually and technically, yes, you can, but not in a way you would ever think.
If it came from Android, it is probably compiled for ARM. So it should be binary-compatible with the ARM CPU in iOS devices. However, iOS doesn't use the usual format of shared objects (that is, the ELF format), but iOS' and OS X's own Mach-O format.
This means that you cannot directly link against this shared object file nor are you able pass it directly to dlopen() and dlsym(). You have to get into serious hacking (something that you probably don't know). This involves loading and relocating the file properly.
An example of this can be found in iOS jailbreak developer and hacker, Comex's GitHub repository Frash, a Flash player for jailbroken iOS devices. Comex essentially wrote an ELF loader module (dubbed "food") for iOS and used it to make Android's libflashplayer.so work on iOS. Pretty neat, huh?
Also note that this is not going to be possible for AppStore apps as it needs dynamic loading and various alterations in the OS.
while technically possible (see h2co3's answer) for anything practical the answer is no
so files arent in the correct binary format
even if they were, dynamic loading is not allowed by appstore
I want to use PhoneGap to make a Cydia app, however the iOS instructions on their website only show how to use it with Xcode.
I don't have a Mac, but I'd like to be able to make my app for Cydia, with theos. Is this possible with PhoneGap, or is it only usable with Xcode?
I've never done this, but YES it should be entirely possible. The Xcode instructions set it up for you to have a specific template with all of the phonegap files already in the proper locations. So it's easy to get going. But it doesn't do anything else that is particularly special. Theoretically you could simply setup all of the files in a theos project.
To do this you will need to 'reconstruct' exactly what goes into a phonegap template. I have no experience with theos, but a rough idea of what you will need to be able to do includes the following:
Import PhoneGap.framework
Reconstruct AppDelegate code
Import Supporting Files (PhoneGap.plist)
Additionally you will need to configure the folder structure with the www folder (that the webview loads from) including the index.html file and the phonegap-1.0.0.js file.
So yes, it should be possible. Let me know if you are successful. Good luck!
