					"body": "This looks valid - although I tested it just a few weeks ago. Let me check this on Monday and come back to you asap!\r\n\r\n*EDIT*: Found it. What a silly error, sorry for that! You can patch your Hyperloop simply by going to {{<project>/modules/iphone/hyperloop/3.1.1/hooks/generate/templates/builtins/titanium.js}} and change line 132 (the selector) from {{registerApplicationDelegate}} to {{registerApplicationDelegate:}}. Same goes for the {{unregisterApplicationDelegate}} and {{unregisterApplicationDelegate:}} if used. It will be added to Hyperloop 3.1.2 asap!\r\n\r\n*EDIT 2*: Ok, so the method works now, but the selector does not seem to be picked up so far. Debugging the iOS source, it looks like the [{{tryToInvokeSelector:}} call|https://github.com/appcelerator/titanium_mobile/blame/7_3_X/iphone/Classes/TiApp.m#L694] returns {{NO}}, indicating that the method selector cannot be resolved. Then I debugged all methods that the generated Hyperloop-class has and it indeed includes the selector:\r\n{code:objc}\r\n- (char) application:(id)arg1 didFinishLaunchingWithOptions:(id)arg2; (0x106ee60c0)\r\n{code}\r\nYou may note that it uses {{char}} instead of {{BOOL}}, but that should still work, since {{BOOL}} extends the {{char}} type. I tried with another selector ({{applicationDidEnterBackground:}}) and it also did not work. The selector for that one looks like this:\r\n{code:objc}\r\n- (void) applicationDidEnterBackground:(id)arg1; (0x106ee6c10)\r\n{code}\r\nWhich is also fine. The only difference is that the \"arg1\" is usually called \"application\", but that should not matter for the selector itself. Finally, I verified that the Hyperloop-defined class indeed implements the {{UIApplicationDelegate}} protocol by using the objc-runtime API {{class_copyProtocolList}} to introspect the class protocol definitions. \r\n\r\nI am running out of ideas, but it may be the selector-argument naming causing this. It works with native modules, so it must be a Hyperloop bug, not SDK bug.\r\n\r\n*EDIT 3*: I create a [pull request|https://github.com/appcelerator/hyperloop-examples/pull/78] to show my current state on this.\r\n\r\n*EDIT 4*: It may be that our Hyperloop-defined classes do not export a proper public header and therefore do not respond to the {{respondsToSelector}} API.",
