  • Cut and paste out of/ into text fields in a separate window doesn't work

    - by Brian Postow
    I have a Macintosh Mozilla plugin which puts up a separate window for login information. It seems to work fine, it gets keyboard events like typing and hitting return to hit the default button. HOWEVER, it doesn't seem to get cut and paste events. When I hit Cmd-v, the edit menu flashes, but nothing happnes. Is this a problem with my responder chain? Do I have to specially tell Mozilla that I want these events? or am I likely to have some other problem that I haven't even thought of? thanks.

  • NSTableView Drag and Drop not working

    - by macatomy
    Hi, I'm trying to set up very basic drag and drop for my NSTableView. The table view has a single column (with a custom cell). The column is bound to an NSArrayController, and the array controller's content array is bound to an NSArray on my controller object. The data displays fine in the table. I connected the dataSource and delegate outlets of the table view to my controller object, and then implemented these methods: - (BOOL)tableView:(NSTableView *)aTableView writeRowsWithIndexes:(NSIndexSet *)rowIndexes toPasteboard:(NSPasteboard *)pboard { NSLog(@"dragging"); return YES; } - (NSDragOperation)tableView:(NSTableView*)tv validateDrop:(id <NSDraggingInfo>)info proposedRow:(NSInteger)row proposedDropOperation:(NSTableViewDropOperation)op { return NSDragOperationEvery; } - (BOOL)tableView:(NSTableView *)aTableView acceptDrop:(id <NSDraggingInfo>)info row:(NSInteger)row dropOperation:(NSTableViewDropOperation)operation { return YES; } I also registered the drag types in -awakeFromNib: #define MyDragType @"MyDragType" - (void)awakeFromNib { [super awakeFromNib]; [_myTable registerForDraggedTypes:[NSArray arrayWithObjects:MyDragType, nil]]; } The problem is that the -tableView:writeRowsWithIndexes:toPasteboard: method is never called. I've looked at a bunch of examples and I can't figure out anything I'm doing wrong. Could the problem be that I'm using a custom cell? Is there something I'm supposed to override in the cell subclass to enable this functionality? EDIT: Confirmed. Switching the custom cell for a regular NSTextFieldCell made dragging work. Now, how do I make drag and drop work with my custom cell?

  • iphone-AVAudio Player Crashes

    - by user2779450
    I have an app that uses an avaudio player for two things. One of them is to play an explosion sound when a uiimageview collision is detected, and the other is to play a lazer sound when a button is pressed. I declared the audioplayer in the .h class, and I call it each time the button is clicked by doing this: NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"/lazer" ofType:@"mp3"]]; NSError *error; audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error]; if (error) { NSLog(@"Error in audioPlayer: %@", [error localizedDescription]); } else { [audioPlayer prepareToPlay]; } [audioPlayer play]; This works fine, but after many uses of the game, the audio will stop play when i hit the button, and when a collision is detected, the game crashes. Here is my crash log: 2013-09-18 18:09:19.618 BattleShip[506:907] 18:09:19.617 shm_open failed: "AppleAudioQueue.41.2619" (23) flags=0x2 errno=24 (lldb) Suggestions? Could there be something to do with repeatedly creating an audio player? Alternatives maybe?

  • Why I can't update my UIImageView?

    - by Tattat
    I make my own UIImageView, like this: @interface MyImageView : UIImageView{ } And I have the initWithFrame like this: - (void)initWithFrame{ UIImage *img = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"myImage" ofType:@"png"]]; CGRect cropRect = CGRectMake(175, 0, 175, 175); CGImageRef imageRef = CGImageCreateWithImageInRect([img CGImage], cropRect); self = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 175, 175)]; self.image = [UIImage imageWithCGImage:imageRef]; [self addSubview:imageView]; CGImageRelease(imageRef); } I want to change the image when the user touchesBegin, so I have something like this: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UIImage *img = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"myImage2" ofType:@"png"]]; CGRect cropRect = CGRectMake(0, 0, 175, 175); CGImageRef imageRef = CGImageCreateWithImageInRect([img CGImage], cropRect); self = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 175, 175)]; [self setImage:[UIImage imageWithCGImage:imageRef]]; CGImageRelease(imageRef); } I find that I can't change the image. So, I add a line [self addSubview:imageView]; in the touchesBegan method, that's work. But I have no idea on why I can't change the image from the touchesBegan, thz.

    - by Madan Mohan
    Hi, I have the data as customerFromDate " 01 Apr 2010 " and customerToDate " 30 Apr 2010 " which is a string. I want to convert that format into yyyy-MM-dd it should be in string. but while doing so. I got null values. Please see the following code which I had tried. printf("\n customerFromDate %s",[customerStatementObj.customerFromDate UTF8String]); printf("\n customerToDate %s",[customerStatementObj.customerToDate UTF8String]); /* prints as the following customerFromDate 01 Apr 2010 customerToDate 30 Apr 2010 */ NSDateFormatter *dateFormatter = [[NSDateFormatter alloc]init]; [dateFormatter setDateFormat:@"yyyy-MM-dd"]; NSDate *fromDate=[[NSDate alloc]init]; fromDate = [dateFormatter dateFromString:customerStatementObj.customerFromDate]; printf("\n fromDate: %s",[fromDate.description UTF8String]); NSString *fromDateString=[dateFormatter stringFromDate:fromDate]; printf("\n fromDateString: %s",[fromDateString UTF8String]); [dateFormatter release]; NSDateFormatter *dateFormatter1 = [[NSDateFormatter alloc]init]; [dateFormatter1 setDateFormat:@"yyyy-MM-dd"]; NSDate *toDate=[[NSDate alloc]init]; toDate = [dateFormatter1 dateFromString:customerStatementObj.customerToDate]; printf("\n toDate: %s",[toDate.description UTF8String]); NSString *toDateString=[dateFormatter1 stringFromDate:toDate]; printf("\n toDateString: %s",[toDateString UTF8String]); [dateFormatter1 release]; Thank you, Madan Mohan.

  • Loading animation Memory leak

    - by Ayaz Alavi
    Hi, I have written network class that is managing all network calls for my application. There are two methods showLoadingAnimationView and hideLoadingAnimationView that will show UIActivityIndicatorView in a view over my current viewcontroller with fade background. I am getting memory leaks somewhere on these two methods. Here is the code -(void)showLoadingAnimationView { textmeAppDelegate *textme = (textmeAppDelegate *)[[UIApplication sharedApplication] delegate]; [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES]; if(wrapperLoading != nil) { [wrapperLoading release]; } wrapperLoading = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 480.0)]; wrapperLoading.backgroundColor = [UIColor clearColor]; wrapperLoading.alpha = 0.8; UIView *_loadingBG = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 480.0)]; _loadingBG.backgroundColor = [UIColor blackColor]; _loadingBG.alpha = 0.4; circlingWheel = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]; CGRect wheelFrame = circlingWheel.frame; circlingWheel.frame = CGRectMake(((320.0 - wheelFrame.size.width) / 2.0), ((480.0 - wheelFrame.size.height) / 2.0), wheelFrame.size.width, wheelFrame.size.height); [wrapperLoading addSubview:_loadingBG]; [wrapperLoading addSubview:circlingWheel]; [circlingWheel startAnimating]; [textme.window addSubview:wrapperLoading]; [_loadingBG release]; [circlingWheel release]; } -(void)hideLoadingAnimationView { [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO]; wrapperLoading.alpha = 0.0; [self.wrapperLoading removeFromSuperview]; //[NSTimer scheduledTimerWithTimeInterval:0.8 target:wrapperLoading selector:@selector(removeFromSuperview) userInfo:nil repeats:NO]; } Here is how I am calling these two methods [NSThread detachNewThreadSelector:@selector(showLoadingAnimationView) toTarget:self withObject:nil]; and then somewhere later in the code i am using following function call to hide animation. [self hideLoadingAnimationView]; I am getting memory leaks when I call showLoadingAnimationView function. Anything wrong in the code or is there any better technique to show loading animation when we do network calls?

  • GNUStep make with a precompiled (and prefixed) .pch header from Xcode project?

    - by d11wtq
    I'm trying to build an Xcode project with GNUStep-make. Right now the project is very small (3 classes) however it will grow to hundreds of classes over the coming weeks so I'm trying to get everything figured out and well-organised now. Xcode creates a ProjectName_Prefix.pch file which is a header that: a) get precompiled and b) is prefixed to every file in my project; at least if I understand correctly. Now, how do I tell GNUStep-make what to do with this file when it builds? I've added it to the XXX_PRECOMPILED_HEADERS variable. Cioccolata_OBJC_PRECOMPILED_HEADERS = Cioccolata_Prefix.pch With this in place the build fails with the error: Making all for framework Cioccolata... make[1]: *** No rule to make target `/Users/chris/Projects/Mac/Cioccolata/build/GNUStep/obj/PrecompiledHeaders/ObjC/Cioccolata_Prefix.pch', needed by `internal-precompile-headers'. Stop. make: *** [Cioccolata.all.framework.variables] Error 2 I've also got the following in my makefile: ADDITIONAL_OBJC_FLAGS += -include Cioccolata_Prefix.pch -Winvalid-pch I'm not sure what I've done wrong here. I basically have tried to follow the GNUStep documentation for precompiled headers. None of my project's source files expressly include the Foundation framework since this header does that.

  • Why I add the CGPoint in the NSMultable Array?

    - by Tattat
    I want to store my CGPoint to the NSMultable Array, so , I have method like this: [self.points addObject:CGPointMake(x, y)]; But I got the error, it said that : Incompatible type for argument 1 of "addObject". So, I check out the API, (void)addObject:(id)anObject anObject The object to add to the end of the receiver's content. This value must not be nil. So, I think the "CGPointMake" can make a Object, but it can't be assigned. What happens?

  • iPhone: Using plist to populate a grouped table

    - by Jack Griffiths
    Hi there, I was wanting to use a plist to populate my grouped table. I've had a look at the DrillDownSave sample project, and I'm still none-the-wiser. Although, I did learn that I could store hierarchies and suchlike in there. So here's the questions: How can I use my plist to add new items to my grouped table? I'm currently feeding the table with an array, and I've noticed that an array isn't going to be the best thing for me. When a user taps on an item in the plist, how can I push the view to the corresponding item? In other words, how can I push the view based on the selected row (which was generated by the plist) to it's next "view"? If that makes any sense, please reply. Thanks, Jack.

  • Core Data (NSFetchedResultsController) displaying one row per section

    - by Urizen
    I have a CoreData application which uses NSFetchedResultsController. NSFetchedResultsController is useful in that it allows me to access the fetched objects more easily etc. but I find that I have problems with the following: I get a crash when I display a single row for each section (irrespective of the number of actual rows present) as a summary of the information in that section (e.g. showing a statistical analysis of the data contained in the fetched rows for that section). I understand that the NSFetchedResultsControllerDelegatemethods have to agree with the number of rows reported per section by the UITableView Delegate method but I would like to be able to fetch all of the records for each section without necessarily displaying each of the rows. The above causes me inconsistency crashes, when I try to insert or delete data for a section, which reports that the number of rows for each section is not as it should be given the number of insertions/deletions. Is there any way I can do what I'm trying to achieve? Thanks for any help.

  • Adding libraries to a project in xcode - symbols not found

    - by kudorgyozo
    I am trying to make an iphone app in xcode that uses pjsip. The problem is I don't know how to link the libraries. I have the ARM version of the libraries in this folder in mac os x. /Users/kudorgyozo/pjsip_iphone In Xcode: I have specified the library and header search paths like this: for includes: /Users/kudorgyozo/pjsip_iphone/pjlib/include /Users/kudorgyozo/pjsip_iphone/pjlib-util/include /Users/kudorgyozo/pjsip_iphone/pjmedia/include /Users/kudorgyozo/pjsip_iphone/pjnath/include /Users/kudorgyozo/pjsip_iphone/pjsip/include for libraries: /Users/kudorgyozo/pjsip_iphone/pjlib/lib /Users/kudorgyozo/pjsip_iphone/pjlib-util/lib /Users/kudorgyozo/pjsip_iphone/pjmedia/lib /Users/kudorgyozo/pjsip_iphone/pjnath/lib /Users/kudorgyozo/pjsip_iphone/pjsip/lib and then using the "Other linker flags" : -lpj-arm-apple-darwin9 -lpjlib-util-arm-apple-darwin9 -lpjmedia-arm-apple-darwin9 -lpjmedia-audiodev-arm-apple-darwin9 -lpjmedia-codec-arm-apple-darwin9 -lpjsdp-arm-apple-darwin9 -lpjnath-arm-apple-darwin9 -lpjsip-arm-apple-darwin9 -lpjsip-simple-arm-apple-darwin9 -lpjsip-ua-arm-apple-darwin9 -lpjsua-arm-apple-darwin9 Is this OK like this? Because it gives me symbol(s) not found errors. I think no symbol is found from the "included" libraries. I don't know what is wrong i'm just beginning to understand how building an app works under linux based systems i've only done programming in C# before.

    - by choise
    Hi guys, in my app i got a TTLauncher Object with some TTLauncherItems in it. Now i want to add some Items dynamically inside my App by pressing a button. Is there a simple way to do that or do i have to create my own methods? In the original facebook application there is already something like that implemented. (You can add your Friends to the Launcher) If not, what would be the best thing to do something like that? Store all "extra items" in a plist oder even in a database and query them, each time TTLauncher object is initialized? Thanks for help :)

  • To store images from UIGetScreenImage() in NSMutable Array

    - by sujyanarayan
    Hi, I'm getting images from UIGetScreenImage() and storing directly in mutable array like:- image = [UIImage imageWithScreenContents]; [array addObject:image]; [image release]; I've set this code in timer so I cant use UIImagePNGRepresentation() to store as NSData as it reduces the performance. I want to use this array directly after sometime i.e after capturing 1000 images in 100 seconds. When I use the code below:- UIImage *im = [[UIImage alloc] init]; im = [array objectAtIndex:i]; UIImageWriteToSavedPhotosAlbum(im, nil, nil, nil); the application crashes. And I dont want to use UIImagePNG or JPGRepresentation() in timer as it reduces performance. My problem is how to use this array so that it is converted into image. If anybody has idea related to it please share with me. Thanks in Advance.
