IKImageBrowserView items image need to download from internet
I am having trouble with IKImageBrowserView, hope you can give me some
guides to find a best solution.
Some background information here about my application: There is a massive of
graphics on the server site, and have been well organized. On the client
site, the application will show customer our graphic collections with
IKImageBrowserView. So every browser item cell should get its image from our
server site through internet connection, for example, web service. Since
there are too many graphics to be shown, we embed the IKImageBrowserView
into Scroller view, customer can scroll to find the best image they want.
like that:
-(id) imageRepresentation
{
if(image of this item is not exist on local)
{
// detach a new thread to download the image asynchronously, through web
service.
// and save it, then return nil.
}
else
{
// return the image immediately, which have been saved on local disk before.
}
}
This piece of code maybe meaningless for you to review my question, but it
will show you how I get the image for the item cell.
The problem comes: when showing the graphics with the IKImageBrowserView,
all the items, more than the visible items, begin to fetch their images
through web service, this makes my web service too busy to handle so many
requests, especially when the customer scroller the view very fast!
And my requirement like this: We don't want a lot of items to download
images at the same time, we need to control the count and order. And also
when customer scroll the image browser view fast, we should forbid the items
which is not visible now to download the items, And let the visible items
have more higher priority to download the image. Basically, what I am
thinking of, is that how to improve the user experience.
Maybe my question is not very clear, but I will be happy if I can get
questions from you. Thanks.

CGImages have no concept of DPI, the DPI is determined by what size of a space you draw them into and the characteristics of the target context. Printing contexts use 72 coordinate points per inch, so if you want to draw an image into a 1" x 1" space with 300 DPI, then the image needs to be 300x300 and drawn into a rect that is 72x72. As far as the rest, I don't know of any controls on printing, but if your image is only slightly larger that would most likely be the problem – an image that is slightly off from the DPI of the target is more likely to look bad than one that is significantly smaller if only because the resampling will distort the image more. -- David Duncan ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Count of records in an NSArrayController when associated NSTableView is filtered
Hi, I have an NSTableView bound to an NSArrayController. I would like to have a dashboard onscreen that shows counts of the data based on field values in the entity, e.g.: all records records with active = Y records with updated = Y records with updated = N Is it possible to bind these values individually to the same NSArrayController? FYI, I have a set of filters on fields on the NSTableView that filter out some of the records for the user. If not, could anyone tell me how I can implement the type of real time counts described above please? I have Googled and read my books but can't work out the answer.

This whole scheme sounds a bit fishy to me... if you are interfacing with a web service, for example, you should probably implement a native UI and use XML, JSON, etc. to talk the the site. I do know that there are some reasons you would want to do this, such as displaying a keypad for numeric entry. This _ought_ to be handled with XHTML's inputmode attribute, which MobileSafari doesn't support. For any Apple engineers out there, I filed a bug a long time ago on this... rdar://6404093 >> How can I hidden, or never show the keyboard.

You would then probably need to present your own view for input on top of/next to the UIWebView and write controller code to send it into the UIWebView. Also see http://stackoverflow.com/questions/2749486/fill-uiwebview-textinput-with-custom-keyboard Sounds like a huge headache to me, though, and again I question the wisdom of what you are trying to do.

crash in initWithCoder
I'm getting a crash in initWithCoder, which seems related to decoding a property called "value", which is of type id. Sometimes this object is an NSString, sometimes it's an NSNumber, and sometimes it's an NSArray. The crash only occurs in cases where "value" is an NSArray. The last few lines in my backtrace are: #0 0x963c4206 in szone_malloc_should_clear () #1 0x963c41a8 in malloc_zone_malloc () #2 0x94920a13 in _CFRuntimeCreateInstance () #3 0x94943482 in CFNumberCreate () #4 0x949586f2 in __CFBinaryPlistCreateObject2 () #5 0x94985fe0 in __CFBinaryPlistCreateObject () #6 0x9823eb11 in _decodeObjectBinary () #7 0x98240314 in -[NSKeyedUnarchiver _decodeArrayOfObjectsForKey:] () #8 0x98240981 in -[NSArray(NSArray) initWithCoder:] () #9 0x9823f508 in _decodeObjectBinary () #10 0x9823e800 in _decodeObject () #11 0x000cdf05 in -[CbCM_Node initWithCoder:] (self=0x4098770, _cmd=0x9433805c, aDecoder=0x410f1c0) at /Volumes/Wheet-Docs/jamesmaxwell/Documents/xcode/rubato/ManuScore+MusiCOG/ManuScore Test Build/ManuScore/CbCM_Node.m:573 From this, I'm guessing that the problem is happening with one of the members of the "value" array.

I'm running > Xcode 4, btw. A crash inside malloc generally means that there's a memory error elsewhere that corrupted malloc's data structures. (Actual bugs in malloc are rare.) malloc may store information before or after each allocation, and inside freed allocations. The usual bugs are: * writing data before or after the bounds of an allocation. Usually this comes from bounds errors in C arrays. * writing data into an allocation after freeing it. NSZombie catches the latter for Objective-C objects. But if the problem is a non-object allocation, or a bounds error, then NSZombie won't help. The next tool to try is Guard Malloc. It catches both of the above errors for any malloc allocation. On the down side, it is slow and memory intensive, but if this -initWithCoder: is running early in app launch then you won't have any trouble with it. http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man3/guardmalloc.3.html -- Greg Parker gpar...@apple.com Runtime Wrangler ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re-mapping secondary function keys
A long time ago, I managed to somehow change the behavior of the expose key (F3) on my MacBook Pro. Instead of Exposeing all windows, it would reveal the desktop. I either found a preference in the UI somewhere, or I set a user default on the command line, or I modified a file in the System somewhere. For the life of me, I can't remember what I did. I'd like to do that on my new computer, but don't remember what I did on the old. Any idea how one changes the behavior of those keys?

Well, it's a general OS development question. Your solution is not the answer. That makes F3 be the "Show Desktop" key, but not the Expose secondary function on that key. There's not really a "general" dev list. This seems as appropriate as the Carbon-dev list.

Re: Count of records in an NSArrayController when associated NSTableView is filtered
assuming I understand (that you want the tableview, but you also want text fields that have these summaries separate)... you could certainly use separate methods with NSPredicates that examine the original data model to return those numbers. If you’re table is filtered you could incorporate that predicate as well. Bindings isn’t an exclusive technology. you can use it with normal programming techniques (in fact, you can do that within the same table., simply don’t bind a column, and then implement the datasource method only for that column - not relevant, but still) On Mar 15, 2011, at 4:55 PM, Darren Wheatley wrote: > Hi, > > I have an NSTableView bound to an NSArrayController. > > I would like to have a dashboard onscreen that shows counts of the data > based on field values in the entity, e.g.: > > all records > records with active = Y > records with updated = Y > records with updated = N > > Is it possible to bind these values individually to the same > NSArrayController?
