barSummaryIf you need to parse data tables, generate object pools, and network connections before loading the main game scene, you can assign a weight to these operations and use these weights to calculate the progress of the LOAD. If your scene loads very fast, you can use a fake progress bar that lets the player look at the loading animation for a few seconds before
problem is that the IMG src assignment is bound to the OnLoad event in the wrong order (in IE and opera, the first assignment is SRC, then the onload, because it is a cached image, it misses the OnLoad event trigger). The OnLoad event should be bound first and then assigned to SRC, with the following code:function LoadImage (URL, callback) { var img = new Image (); // Create an Image object that enables pre-download of the picture img.onload = function () { Img.onload = null; Callback (IMG)

, we can also retain the member initialization code in the initWithNibName method. However, the code in the original viewDidLoad method is moved to the appear method. That is, it is recommended that you do not initialize a member in the viewDidLoad method. In this way, the code in the appear method will be executed every time the presentViewController is used (if it is the viewDidLoad method, it will only be executed when the nib is loaded ).Loadview is also called 1st times when ViewController&
