* iOS: Forward [UIApplicationDelegate handleOpenURL:] to QDesktopServicesTor Arne Vestbø2013-11-291-0/+20
| | | | | | | | | | | | | | | | | | The user may use QDesktopServices::setUrlHandler() in combination with the appropriate Info.plist keys (CFBundleURLTypes, CFBundleURLSchemes) to react to URL requests from other applications. This is among other things useful for handling OAuth authentication from applications such as Dropbox. See: https://www.dropbox.com/developers/core/start/ios We protect against recursive URL opening, but an application may still redirect a request to open a URL by opening another URL, eg a website.

* iOS: Interleave Qt application main() with iOS startup sequenceTor Arne Vestbø2013-09-131-23/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our previous event loop integration had two unfortunate flaws: 1. We would call qt_user_main() from a timer, after returning from didFinishLaunchingWithOptions. This had the effect of showing the iOS application window long before the Qt application UI had been set up, resulting in a 1-2 second flash of black/pink between the launch image disappearing and the actual application showing. 2. We spun a nested event loop, where our implementation of the different event loop modes did not perfectly match the Apple implementation. This resulted in scrolling being busted in some cases such as when showing the virtual keyboard for Emoji characters. These two issues have now been solved by calling the user's main() from didFinishLaunchingWithOptions. Normally this would not work, as the user's main would call QApplication::exec() at the end of their main(), which would block and we would never return back from the didFinishLaunchingWithOptions callback, resulting in no UI on screen. We work around this by longjmp'ing out of QApplication::exec(), back into didFinishLaunchingWithOptions, so that it can return. Again, this would normally not work, as the call stack where QApplication and friends would live would get smashed as the application continued executing. We work around this by allocating a block of stack space at the start of main(), which we then redirect the stack pointer to before calling the user's main. This results in the whole stack of the user's main() and below being preserved, even if we longjmp out of the call stack (which then restores the stack pointer). This approach should work fine together with garbage-collection as well, since the mark-and-sweep phase will walk the stack from the stack pointer to the stack base, including sections of the stack that were part of qt_user_main() and live in the reserved area. One case where GC will fail though is if it happens as part of the qt_user_main() call, where the GC will not mark anything in the 'real' callstack below UIApplicationMain(), but this is not expected to happen. The size of the reserved stack can be controlled through the Info.plist key 'QtRunLoopIntegrationStackSize', as well as the 'QtRunLoopIntegrationDisableSeparateStack' key to disable the separate stack approach completely. This will fall back to the old approach. The amount of stack space used by the user's main can be determined by enabling a special debugging mode, using the 'QtRunLoopIntegrationDebugStackUsage' key.

* iOS: Change main-wrapper logic to not require changing the user's mainTor Arne Vestbø2013-09-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using a define to rename the user's main() function during compilation, we leave the user code alone, and inject our wrapper one step earlier in the process, at the application entry point 'start'. This entry point is provided by crt1.o, which is normally linked into the application automatically. The start() function sets up some state and then calls main(), but we change the start() function to instead call our main wrapper. Instead of shipping our own crt1 binary/sources, we make a copy of the appropriate crt1.o at build time, and modify its symbol table in place. This is unproblematic as long as we keep the same length for the wrapper function name, as the symbol names are just entries in the global string table of the object file. The result is that for the regular Qt use-case the user won't see any changes to their main function, and we have more control over the startup sequence. For the hybrid use-case, we no longer rely on the fragile solution of having our back-up 'main' symbol in a single translation unit, which would break eg with --load_all, and we don't need to provide a dummy 'qt_user_main' symbol. OSX 10.8 and iOS 6.0 introduced a new load command called LC_MAIN, which places the state setup in the shared dyld, and then just calls main() directly. Once we bump the minimum deployment target to iOS 6.0 we can start using this loader instead of LC_UNIXTHREAD, but for now we force the classic loader using the -no_new_main flag. There's also a bug in the ld64 linker provided by the current Xcode toolchains that results in the -e linker flag (to set the entry point) having no effect, but hopefully this bug has been fixed (or Apple has switched to the LLVM lld linker) by the time we bump our deployment target.

* iOS: Remove need for separate qtiosmain libraryTor Arne Vestbø2013-06-121-1/+47
| | | | | | | | | | | | | | | | | | | | We can combine the hybrid and non-hybrid use-cases into a single static library if we are careful about which symbols are included in which object files. By limiting the main() and qt_user_main() functions to their own translation units, the linker will only pick them up if they are missing at link time (the user's program do not provide them). This technique is resilient to the -ObjC linker flag, which includes all object files that implement an ObjectiveC class or category, but will fail if the -all_load flag is passed to the linker, as we'll then have duplicate symbols for either main() or qt_user_main(). The latter should not happen unless the user provides the flag manually, and in the case he or she does, there's ways to work around it by providing less global flags such as -ObjC or -force_load.

* iOS: use an explicit pointer to qiosViewControllerRichard Moe Gustavsen2013-04-191-0/+2
| | | | | | | | | | | | | As it stood, we always relied on the root view controller being a QIOSViewController if isQtApplication() returned true. For mixed application, this might not always be true as native code can choose to replace the root view controller at times, or even rip it out, and place it as a child of another (e.g UISplitViewController). This change will give an extra protection against that. Change-Id: I0cb85796a8b82f9037c32f9e85e04e1dc7aad8e2 Reviewed-by: Tor Arne Vestbø <tor.arne.vestbo@digia.com>
* iOS: Ensure UIApplicationMain is started before QApplication by wrapping main()Tor Arne Vestbø2013-02-271-23/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the typical Qt app the developer will have an existing main() that looks something like: int main(int argc, char *argv[]) { QGuiApplication app(argc, argv); return app.exec(); } To support this, we provide our own 'main' function in the qtmain static library that we link into the application, which calls UIApplicationMain and redirects to the 'main' function of the application after the event loop has started spinning. For this to work, the applications 'main' function needs to manually be renamed 'qt_main' for now. In a later patch, this renaming will happen automatically by redefining main from either a header file, or more likely, from the Makefile created by qmake. For the case of an iOS developer wanting to use Qt in their existing app the main will look something like: int main(int argc, char *argv[]) { @autoreleasepool { return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class])); } } This is supported right now by just linking in libqios.a without libqiosmain.a. QGuiApplication should then be created e.g inside the native apps application delegate (but QGuiApplication::exec should not be called). In the future, we plan to but use a wrapper library that brings in all the Qt dependencies into one single static library. This library will not link against qtmain, so there won't be a symbol clash if the -ObjC linker option is used. We should then add the required magic to the future Objective-C convenience wrapper for QML to bring up a QGuiApplication, which would allow using Qt from storyboards and NIBs. This would also be the place to inject our own application delegate into the mix, while proxying the delegate callbacks to the user's application delegate.
