Nimblekit 1.5.8 alfa 2

[sunny]

As many of you requested to fix "white screen" on initial application loading I decided to include fix for this in 1.5.8 release.
This is very specific bugfix so I want to ask you to test it before I release, thank you.

As usually for betas to install you have to unzip attached archive and copy the contents to /Library/Frameworks/
then open Xcode and click in main menu "Xcode->Empty caches" and "Build->Clean All Targets"

Also NimbleKit template will be modified after release, but for now to test it you will have to modify you APP_NAME_Delegate.m file in your project:
1. Locate @implementation NimbleAppDelegate in the file and right before this line insert extern BOOL _mainWebViewLoaded;
2. In the method - (void)applicationDidFinishLaunching:(UIApplication *)application locate line [nimble release]; and right after it insert

Code: Select all

while (!_mainWebViewLoaded) {
      [[NSRunLoop currentRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:1]];
   }   

After this you should see Default.png file during app is loaded and when it disappears you should see you main application screen fully loaded, also be aware that if you load something from the internet it may take a lot of time and the default screen will still remain on the top which can make user think the app has freeze so please avoid using internet connection on the main application screen

Also using the kind of preloading you can also launch asynchronous preload of other static pages, for instance if you use jquery you could see white screen too when you move to the page first time. To avoid this you can preload page. To do that just insert to your - (void)applicationDidFinishLaunching:(UIApplication *)application method code:

Code: Select all

[[NSClassFromString(@"NKBridge") sharedInstance] performSelector:@selector(webViewForPage:) withObject:@"pagetopreload.html"];

right before [nimble release]; You can preload as many pages as you want, but they all load asynchronous in background, preloading many pages can affect performance.

When I add the code to the appdelagate file I never get past the default.png

Here's what I have for the top of my file

Code: Select all

extern BOOL _mainWebViewLoaded;
@implementation MyAppDelegate

@synthesize window;


- (void)applicationDidFinishLaunching:(UIApplication *)application {
   while (!_mainWebViewLoaded) {
      [[NSRunLoop currentRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:1]];
   } 
   
   Nimble *nimble = [[Nimble alloc] initWithRootPage:@"main.html" window:window serial:@"XXXX-XXXX-XXXX-XXXX"];
   [window addSubview:nimble.view];
   [window makeKeyAndVisible];
   [nimble release];
}

Am I missing something or do something wrong?

On a different note... I can now play ALL of my companies AAC files... so once 1.5.8 goes gold... I get to start cranking apps out

[sunny]

yes, the lines order is wrong in you code, see my delegate file as example:

Code: Select all

#import "NimbleAppDelegate.h"
#import "Nimble.h"

extern BOOL _mainWebViewLoaded;
@implementation NimbleAppDelegate
@synthesize window;
- (void)applicationDidFinishLaunching:(UIApplication *)application {    
   Nimble *nimble = [[Nimble alloc] initWithRootPage:@"main.html" window:window serial:@""];
   [window addSubview:nimble.view];
   [window makeKeyAndVisible];
   [nimble release];
   while (!_mainWebViewLoaded) {
      [[NSRunLoop currentRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:1]];
   }   
}
- (void)applicationWillTerminate:(UIApplication *)application
{
   [[NSClassFromString(@"NKBridge") sharedInstance] performSelector:@selector(onApplicationQuit)];
}
- (void)dealloc {
    [window release];
    [super dealloc];
}
@end

also make sure you added extern BOOL _mainWebViewLoaded; in the exact place like in my file

Tried this on 2 apps.

First app with 2 pages works perfectly - and the preload functionality is perfect.

Second app uses a NKTabBarController with 4 tabs & NKNavigationController on first page. When app loads again all is fine but when I go to another page the NavController setTitle function seems to be broken - ie no title is displayed on the nav bar at the top of the page.

[sunny]

I'm working on navigation controller now, it may be broken now... also try not to preload pages if it still be not working then yeah, just alfa issue to be fixed soon

[blazeman]

thanks sunny... that fixed it for me

This works perfectly for me if I compile against OS 3.0 or above, but not if I compile for OS 2.2.1. Is there a quick fix for that? Or is 2.2.1 just a bad idea?

Is this on Xcode 3.1 or 3.2? By default 2.2.1 isn't installed any more. You need to select it when installing the SDK.

[blazeman]

I think I read your post wrong Sorry.

Mine is working fine for 2.2.1.

What are your errors?
