  • Is there a better way of launching same app from GUI or Command line

    - by markhunte
    Hi All, I worked out a way of running my Cocoa (GUI) app. From either the normal double clicking it, Or from the CLI. I realised that when an app launches from a double click (GUI), it returns an argument count (argc) of 0. But when launched from the CLI it will have an argc of 1. So long as I do not put any arguments myself. Which means I can use if.. else.. to determine how the app was launched. This works fine for my app as I do not need to put arguments. But I wondered if there was a better way of doing it. Here is an example of the code in the main.m int main (int argc, const char * argv[]) { //This determins if the app is launched from the command line or app itself is opened. if (argc == 1) { //app was run from CLI // Create a object MyClass *mMyClass; mMyClass = [[MyClass alloc] init]; // Read the Buffer [mMyClass readBuffer]; // Write out file on disk [mMyClass createFile]; [mMyClass doMoreStuff]; [mMyClass release]; mMyClass = nil; return 0; } else { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; //app was doubled click, (Opened) return NSApplicationMain(argc, (const char **) argv); [pool drain]; // */ // return NSApplicationMain(argc, (const char **) argv); }} Many Thanks.

  • IKImageView, Buttons work intermittently in 10.5 but ok in 10.6

    - by markhunte
    Hi all, In IB,I have connected some buttons to a IKImageView. Using its received Action 'ZoomIn:', 'ZoomOut:','ZoomImageToActualSize:' When I build for 10.6 I have no issues these work as expected. But in 10.5 (ppc), they sometimes work as expected and sometimes do not. I have even tried it programatically. But I get the same results. It is intermittent with each build after I have made some small change in IB that I need. But not changes that should affect how the view acts. The only buttons that seem to work through out are 'ZoomImageToFit' and the rotate ones. When the do not work as expected, I see no change to the current image in the view, but when my app (/s, I have had this issue before in different apps) changes the image The view reflects the last request from a button. So for example when it does not work. An image is displayed, I click the 'ZoomImageToActualSize:' button, nothing happens. I load a new image and it is displayed at Actual size. Example when it does work. An image is displayed, I click the 'ZoomImageToActualSize:' button, It is displayed at Actual size. By the way, I know I can reset the view default , before I load a new image. Also if I run the 10.5 app in 10.6, it works ok, but as above I get intermittent results with the same build on multible 10.5 machines. Does anyone know what is going on, is this a known bug? Thanks for any help. MH
