iphone - Apple Lazy Loading Images within a nav controller, reverts back to placeholder images -

-

I implemented the LazyTableImages project () by Apple, but in my version I used RestKit to get data And my UItableviewcontroller was pushing

on the navigation stack so I would leave whatever Apple does to get xml in the applet. I think that this problem is not My problem is that when you come back from the UITB visual controller using the NAV back button or using any other tabbar object and come back, then the images which were previously loaded there, but immediately load the placeholder image Actually, the opposite happens.

This UITableview is like cached data, so when you come back, lazy tables interfere with images. I need to know that someone has implemented this code where they had to be repelled?

EDIT:

Looks like the image downloader is not zero for the second time, which prevents the image from loading. I'm still finding out how to bypass it. Of course, I can only take out the condition, but I do not know that it is "bad" for performance.

imageDownloadsIn progress, a temporary dictionary, is still all your data even though you are back. It has now become a different question, how do I delete the image? Downloading if a user is back from the current view or chimes

imageDownloadsInprogress is maintained, but I added [imagesDownloadsInprogress release] to the dealloc method, although I do not think that runs. Download the startEventImage: (WhatsonEvent *) EventRecord forIndexPath: (NSIndexPath *) IndexPath {Event ImageDownloader * ImageDownloader = [ImageDownloadsInfographic Objectworks: IndexPath]; If (imageDownloader == zero) {NSLog (@ "% @", eventRecord.title); Imagedownloader = [[Event Image Downloader Alloc] init]; Imagedownloader.eventRecord = eventRecord; ImageDownloader.indexPathInTableView = indexPath; Imagedownloader.delegate = self; [Image Download Progress Set Object: Downloader for Image: IndexPath]; [Download image downloader]; [Image downloader release]; [UIApplication ShareApp] .networkActivityIndicatorVisible = YES; }}

The way I do it is to create my own cache and save images When I call [tableView reloadData] in the user document directory (you say it, is not it?) It checks for each cell first, if the image is locally, otherwise it will be free Tell me if you want a code for it.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered. Especially when trying to connect like the example for Mono Touch string dbName = path. Cobain (environment.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
