clearing a webview after use
In my application (OSX) I implemented an NSPopover that displays a webview to show more info on a a particular item in my model (which are listed in an NSTableView). So the user doubleclicks the table, and the popover appears and shows the website related to that item. I implemented back and forward buttons in case the user wants to browse through the view in the popover. When the popover closes, I call: setMaintainsBackForwardList:NO for the webview to clear the history, because I don't want that to be available when the webview is opened for another item. So far so good, this all works very well. Now when the user opens the popover for another item, I often first see the previous page that was shown in the webview, which doesn't look right to me. Is there a way to empty or clear a webview when I close the popover, so that next time it is opened it doesn't show the previous page? I don't want to clear the cache, because when the webview is opened for an item that was already selected, it can be loaded from the cache. - Koen. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Debugging NSWindowController and NSArrayController
Hi, I have an NSWindowController that creates an instance of NSManagedObjectContext. That window controller loads a NIB that has a table populated by an NSArrayController bound to the MOC in the window controller. This was done via Interface Builder. The array controller is set to retrieve Entities of type X. On the init method of my window controller I add an object of type X to the MOC and I can see it's there because I can fetch it on windowDidLoad but for some reason the array controller on the NIB doesn't see any data. If I fire up gdb and do *po [arrayController arrangedObjects]* I get an empty array. Is there any other way of debugging this? -- Rui Pacheco ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

UINavigationBar appearance not updating
I want to give a hint in my app whether you are or are not using iCloud. As
most screens have a navigation bar, I thought that changing the tint color of
that would be a nice visual effect, it's not bad, not sure I'm fine with it yet
but working on it.
To do it I'm using the UIAppearance protocol, here's the method which does the
work.
-(void)updateTintsForICloud
{
BOOL usingICloud = [ [ HIPSettings sharedSettings ] usingICloud ];
[ [ UINavigationBar appearance ] setTintColor:usingICloud ? [ UIColor
colorWithRed:0 green:0 blue:.3 alpha:1.0f ] : [ UIColor clearColor ] ];
}
Not too complicated.
This runs on iPhone and iPad. On iPhone the screen which switches between
iCloud and local is a full-screen modal popover. It covers over what is
currently displayed on the screen (the navigation stack) and at the end it
eventually calls updateTintsForICloud on exit. Works fine, when the nav stack
re-shows on-screen the navigation bar has been updated to the new tint.
On iPad it's the same view, but it's presented as a modal formsheet, so the nav
stack behind it dims but continues to display and the form sheet shows up as a
box in the middle of the screen. The same logic follows, updateTintsForICloud
is still called, the UINavigationBar appearance is changed but .. it doesn't
actually update the on-screen nav bar, nor any subsequent navbar pushes.
My assumption is that the difference is with iPad the old navigation bar stays
on-screen, albeit dimmed, and so doesn't re-draw and pick up the new defaults,
with iPhone it is totally covered up and so gets a redraw when it uncovers.
Is there a method I've missed which tells UIAppearance to update currently
visible elements, or do I have to write some code to update any currently
showing nav bar with the current tint hint? I have perused the stuff about
UIAppearance but it's quite thin and not totally helpful.

Question about hebrew in textfields and textviews
Dear Cocoa-devs, Working with a person using hebrew input method. Text appears right-to-left as desired, but all of the textfields and textviews are still left justfiied, so it looks a little weird.

AVQueuePlayer
Hi, I'm working on Lion-application that uses AVQueuePlayer to play a list of video-files, that should seemlessly play as if they're one large movie. i was thinking AVQueuePlayer would be able to do this out of the box, by feeding it AVPlayerItems (as they become available) while playing. The result however is not what i expected; Sound seems to play fine, without any (noticable?) hickups, but the video-image is very unstable: It starts-out displaying fine, but it freezes when switching between items, sometimes for several seconds, and then it all of a sudden fast-forwards to catch-up with the sound again. The video's that are being played are local files of very modest resolutiuon/bitrate (480x272 @ 25fps - ± 2Mbit/s) i don't receive any notifications indicating that something is wrong. A timeobserver attached to the player reports the time correctly, also during video-freezes. Am i overlooking something obvious? What's going wrong? thanks, arri ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Thanks for all the replies. Unfortunately NSNaturalTextAlignment doesn't seem to affect the justification of the textfields.

Re: AVQueuePlayer ( stuttering/freezing - dissapointing playback )
HI Rob, thanks for your input! Yes, all files are identical. And no, i'm not 'manually' preloading/-rolling anything (is that possible at all?) And i was asuming that AVQueuePlayer would be doing this automatically... Basically AVPlayer already does what i want when it plays live an HTTP-stream from a m3u8 playlist with '.ts' segment-files. I have thought of the option of 'serving' a local '.m3u8' playlist containing the video files, but that seems a bit odd to me .. and it could possibly introduce a ton of new problems. gr arri On Wed, Apr 11, 2012 at 9:49 PM, Robert Martin wrote: > I'm a patzer, not an expert - but a couple of thoughts occurred: > > Are all files the same dimensions and compressed identically? > > There's also probably some latency in opening and pre-rolling a movie - d= epending on the codec.

A question about core data.
Hello, I have started a billing project with coco and core data. In my project, I have a form that the user must fill to add a customer (for example) but it seems that core data have only an array controller with a manage object context to manage the core data database. Is it true ? In some language (such as java), I can send some sql query to the database. such as (insert into Customeer etc..), I can also send a set of query (transaction). On the apple website, in a guide, I have reed an information about fetch request How it work ? Can the fetch request help me in my project ? Tanks for your help ?

Networking and sleep
I have an app which attempts to make an internet connection after receiving an NSWorkspaceDidWake notification. Most of the time, the connection fails with the error, "...internet connection appears to be offline (-1009)". My guess is the the OS has not yet reinitialized networking before my app attempts to connect. So I added a sleepForInterval:10 to make my app wait a bit before connecting. This seems to work just fine, but question is: Is there a more elegant way to handle this?

Re: Question about hebrew in textfields and textviews
First of all, it's true that having fields with natural directionality will give you the proper runtime directionality (RTL/LTR) depending on the language in which the user is typing. To my knowledge, that doesn't affect the alignment (left/right), even if it would make sense for it to do so. If your app is not localized (i.e., you're just allowing text input, not actually providing a fully translated interface), you'll need to change the alignment based on the currently selected language. Is this what you are aiming for? Aviah Morag amo...@apple.com On 11 באפריל 2012, at 10:26, Kyle Sluder wrote: > On Apr 11, 2012, at 10:17 AM, Matthew Weinstein wrote: > >> Thanks for all the replies.
