  • ApplicationDelegate is not doing its own job here ! Can anyone help me??

    - by ahmet732
    (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { MaSystemGuiAppDelegate *appDelegate = (MaSystemGuiAppDelegate *)[[UIApplication sharedApplication] delegate]; appDelegate.deneme = [tableData objectAtIndex:indexPath.row] ; NSLog(@"my row", appDelegate.deneme); // THIS IS NOT PRINTING NSLog(@"my row = %@", [tableData objectAtIndex:indexPath.row]); //THIS IS PRINTING THE VALUE ON CONSOLE NSInteger row = [indexPath row]; if(self.searchDetailViewController == nil){ SearchDetailViewController *asearchDetail = [[SearchDetailViewController alloc] initWithNibName:@"SearchDetailView" bundle:nil]; self.searchDetailViewController = asearchDetail; [asearchDetail release]; } searchDetailViewController.title = [NSString stringWithFormat:@"%@", [searchArray objectAtIndex:row]]; MaSystemGuiAppDelegate *delegate = [[UIApplication sharedApplication] delegate]; [delegate.searchNavController pushViewController:searchDetailViewController animated:YES]; } "deneme" is a NMUtableArray is identified in MaSystemGuiAppDelegate.h (I identified it as a variable and put its property there) and I wrote "deneme= [[NSMutableArray alloc]init]; in applicationDidFinishLaunching method in MaSystemGuiAppDelegate.m. In the code above, [tableData objectAtIndex:indexPath.row] is retrieving the one of the value touched on tableview. When I put that value in deneme (as u noticed in the code) it is printing nothing. What am i missing? (I imported MaSystemGuiAppDelegate.h)

  • Cocos2d - smooth sprite movement in tile map RPG

    - by Lendo92
    I've been working on a 2-D Gameboy style RPG for a while now, and the game logic is mostly all done so I'm starting to try to make things look good. One thing I've noticed is that the walking movement / screen movement is a little bit choppy. Technically, it should work fine, but either it seems to be having some quirks, either due to taking up a lot of processing power or just timing inconsistencies between moving the screen and moving the sprite. To move the sprite, once I know where I want to move it, I call: tempPos.y += 3*theHKMap.tileSize.width/5; id actionMove = [CCMoveTo actionWithDuration:0.1 position:tempPos]; id actionMoveDone = [CCCallFuncN actionWithTarget:self selector:@selector(orientOneMove)]; [guy runAction:[CCSequence actions:actionMove, actionMoveDone, nil]]; [self setCenterOfScreen:position]; Then, in orientOneMove, I call: [self.guy setTexture:[[CCTextureCache sharedTextureCache] addImage:@"guysprite07.png"]]; //the walking picture-I change texture back at the end of the movement id actionMove = [CCMoveTo actionWithDuration:0.15 position:self.tempLocation2]; id actionMoveDone = [CCCallFuncN actionWithTarget:self selector:@selector(toggleTouchEnabled)]; [guy runAction:[CCSequence actions:actionMove, actionMoveDone, nil]]; The code for the concurrently running setCenterOfScreen:position method is: id actionMove = [CCMoveTo actionWithDuration:0.25 position:difference]; [self runAction: [CCSequence actions:actionMove, nil, nil]]; So the setCenterOfScreen moves the camera in one clean move while the guy moving is chopped into two actions to animate it (which I believe might be inefficient.) It's hard to tell what is making the movement not perfectly clean from looking at it, but essentially the guy isn't always perfectly in the center of the screen -- during movement, he's often times a pixel or two off for an instant. Any ideas/ solutions?

  • dismissViewControllerAnimated completion block presenter view and modal view flow

    - by Patricia LaRue
    I did find an answer to this title and I did do a little research but I'm still not getting the flow. Here is what I want to happen: 1) click a button on the presenter view to open a modal view. 2) retrieve some value and click a button to close the modal view....sending the value to the presentor view and execute a method. I get that this works like a callback but I still can't figure out where to put the callback stuff. So, how exactly do I do this? A) In the presentViewController completion block, should I include the presenter view method to execute when modal view is completed? Or: B) In the modal view's dismissViewControllerAnimated completion block, should I include the presenter view method to execute when modal view is completed? Can somebody help me with some sample code? Or at least help me get the flow of which block to put the code in? Thank you, P

  • Cocoa : How do I catch drag operations initiated from an IKBrowserView?

    - by bucketmouse
    So I've got an IKBrowserView all wired up and happily dragging my custom datatype (provided lazily via PasteboardItem) from one window to another, but now I'm interested in detecting when the user drops some data onto the trashcan. Cocoa's documentation says to check the return type of the drag operation itself, but how exactly do I do this with an IKBrowserView? Once I call imageBrowser:writeItemsAtIndexes:toPasteboard: I don't seem to get any notifications other than the request for the pasteboard contents, which doesn't provide a pointer to the drag operation that invoked it.

  • Why is the compiler caching my "random" and NULLED variables?

    - by alex gray
    I am confounded by the fact that even using different programs (on the same machine) to run /compile, and after nilling the vaues (before and after) the function.. that NO MATTER WHAT.. I'll keep getting the SAME "random" numbers… each and every time I run it. I swear this is NOT how it's supposed to work.. I'm going to illustrate as simply as is possible… #import <Foundation/Foundation.h> int main(int argc, char *argv[]) { int rPrimitive = 0; rPrimitive = 1 + rand() % 50; NSNumber *rObject = nil; rObject = [NSNumber numberWithInt:rand() % 10]; NSLog(@"%i %@", rPrimitive, rObject); rPrimitive = 0; rObject = nil; NSLog(@"%i %@", rPrimitive, rObject); return 0; } Run it in TextMate: i686-apple-darwin11-llvm-gcc-4.2 8 9 0 (null) Run it in CodeRunner: i686-apple-darwin11-llvm-gcc-4.2 8 9 0 (null) Run it a million times, if you'd like. You can gues what it will always be. Why does this happen? Why oh why is this "how it is"?

  • asynchronous method executing

    - by alexeyndru
    I have a delegate method with the following tasks: get something from the internet (ex: some image from a web site); process that image in a certain way; display the result in a subview ; getting the image takes some time, depending on the network's speed so the result of its processing is displayed in the subview after that little while. my problem: during the time between getting the image and showing the result the device looks unresponsive. any attempt to put some spinner, or any other method which is called inside this main procedure has no effect until the result is processed. how should I change this behaviour? I would like to put a big spinner during that waiting time. thank you.

  • Strange behaviour of NSScanner on simple whitespace removal

    - by Michael Waterfall
    I'm trying to replace all multiple whitespace in some text with a single space. This should be a very simple task, however for some reason it's returning a different result than expected. I've read the docs on the NSScanner and it seems like it's not working properly! NSScanner *scanner = [[NSScanner alloc] initWithString:@"This is a test of NSScanner !"]; NSMutableString *result = [[NSMutableString alloc] init]; NSString *temp; NSCharacterSet *whitespace = [NSCharacterSet whitespaceCharacterSet]; while (![scanner isAtEnd]) { // Scan upto and stop before any whitespace [scanner scanUpToCharactersFromSet:whitespace intoString:&temp]; // Add all non whotespace characters to string [result appendString:temp]; // Scan past all whitespace and replace with a single space if ([scanner scanCharactersFromSet:whitespace intoString:NULL]) { [result appendString:@" "]; } } But for some reason the result is @"ThisisatestofNSScanner!" instead of @"This is a test of NSScanner !". If you read through the comments and what each line should achieve it seems simple enough!? scanUpToCharactersFromSet should stop the scanner just as it encounters whitespace. scanCharactersFromSet should then progress the scanner past the whitespace up to the non-whitespace characters. And then the loop continues to the end. What am I missing or not understanding?

  • Automatically hide toolbar when it is not in use.

    - by Koning WWWWWWWWWWWWWWWWWWWWWWW
    I am creating a Cocoa Application for Mac OS 10.6 , and I want to hide the toolbar of an NSWindow automatically when it is not in use for at least 30 seconds. I think this can be done with NSTimers, but I'm not familiar with them and I don't know how I can implement this. Another problem is that both the NSToolbarDelegate and NSWindowDelegate protocols don't have delegate methods like toolbarDidShow: Can anyone point me in the right direction? Thanks. PS. This is not to punish the user, but rather give the user a cleaner window (the window consist of only a toolbar for color and font and a text-view). PPS. Can the hide-toolbar-animation lead into a problem with the cursor while the user is typing?

  • Effect of 'myObj = [[[[MyClass alloc] init] autorelease] retain];'?

    - by filipe
    I've just downloaded the Facebook iOS SDK and I noticed that in the sample code that comes with the SDK whenever it creates an instance of the Facebook class it does it like this: _facebook = [[[[Facebook alloc] init] autorelease] retain]; where _facebook is a member variable of the calling object (i.e. not a local variable). Can anyone explain exactly what's the point of autoreleasing and then retaining it?

  • With ARC why use @properties anymore?

    - by trapper
    In non-ARC code retained properties handily take care of memory management for you using the self.property = syntax, so we were taught to use them for practically everything. But now with ARC this memory management is no longer an issue, so does the reason for using properties evaporate? is there still any good reason (obviously other than providing public access to instance variables) to use properties anymore?

  • Sqlite iPhone data insertion problem

    - by Asad Khan
    Hi I have a function which basically tries to insert some data returned from a REST call. - (void)syncLocalDatabase{ NSString *file = [[NSBundle mainBundle] pathForResource:@"pickuplines" ofType:@"db"]; NSMutableString *query = [[NSMutableString alloc] initWithFormat:@""]; sqlite3 *database = NULL; char *errorMsg = NULL; if (sqlite3_open([file UTF8String], &database) == SQLITE_OK) { for(PickUpLine *pickupline in pickUpLines){ [query appendFormat:@"INSERT INTO pickuplines VALUES(%d,%d,%d,'%@','YES')", pickupline.line_id, pickupline.thumbsUps, pickupline.thumbsDowns, [pickupline.line stringByReplacingOccurrencesOfString:@"'" withString:@"`"]]; NSLog(query); int result = sqlite3_exec(database, [query UTF8String], NULL, NULL, &errorMsg); if (result!=SQLITE_OK) { printf("\n%s",errorMsg); sqlite3_free(errorMsg); } //sqlite3_step([query UTF8String]); [query setString:@""]; }//end for }//end if [query release]; sqlite3_close(database); } everything seems fine query string in log statement is also fine but the data does not gets inserted. Where as a counterpart of this function for select statement works well. Here is the counter part - (void)loadLinesFromDatabase{ NSString *file = [[NSBundle mainBundle] pathForResource:@"pickuplines" ofType:@"db"]; sqlite3 *database = NULL; if (sqlite3_open([file UTF8String], &database) == SQLITE_OK) { sqlite3_exec(database, "SELECT * FROM pickuplines", MyCallback, linesFromDatabase, NULL); } sqlite3_close(database); } I have implemented callback & it works fine. I am a little new to Sqlite can someone please point out what am I doing wrong. Thanx

  • Setting shadowColor with property syntax gives compiler error: Expected identifier before '[' token.

    - by sam
    I have an iPad app in which I'm setting the shadow color of a UILabel in a UIView's initWithFrame: method. When I use the following syntax: m_label.shadowColor = [UIColor colorWithWhite:1.0 alpha:0.5]; I get this compiler error: Expected identifier before '[' token However, when I use the following syntax: [m_label setShadowColor:[UIColor colorWithWhite:1.0 alpha:0.5]]; It compiles without complaint. Using property syntax for other properties of the UILabel is working fine (shadowOffset, autoresizingMask, backgroundColor, font, textColor, etc.). Incidentally, I get the same error message when the statement is simply this: m_label.shadowColor; Whereas this, for example, gives no error: m_label.shadowOffset; FWIW, the entire method looks like this: #define shadowColor [UIColor colorWithWhite:1.00 alpha:0.5] #define selectedColor [UIColor colorWithWhite:0.25 alpha:1.0] #define unselectedColor [UIColor colorWithWhite:0.45 alpha:1.0] #define CLOSEBUTTON_WIDTH 26.0 #define CLOSEBUTTON_HEIGHT 26.0 - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { m_imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0.0, 0.0, self.frame.size.width, self.frame.size.height)]; m_imageView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; m_imageView.backgroundColor = [UIColor clearColor]; m_imageView.image = [[UIImage imageNamed:@"tab.png"] stretchableImageWithLeftCapWidth:8.0 topCapHeight:0.0]; m_imageView.highlightedImage = [[UIImage imageNamed:@"tabSelected.png"] stretchableImageWithLeftCapWidth:8.0 topCapHeight:0.0]; m_label = [[UILabel alloc] initWithFrame:CGRectZero]; m_label.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; m_label.backgroundColor = [UIColor clearColor]; m_label.font = [UIFont boldSystemFontOfSize:12.0]; m_label.textColor = unselectedColor; m_label.shadowOffset = CGSizeMake(0.0, 1.0); m_label.shadowColor = shadowColor; // Expected identifier before '[' token [m_label setShadowColor:shadowColor]; m_closeButton = [[UIButton alloc] initWithFrame:CGRectMake(9.0, 1.0, CLOSEBUTTON_WIDTH, CLOSEBUTTON_HEIGHT)]; [m_closeButton setBackgroundImage:[UIImage imageNamed:@"tabClose.png"] forState:UIControlStateNormal]; [m_closeButton addTarget:self action:@selector(closeTab) forControlEvents:UIControlEventTouchUpInside]; [self addSubview:m_imageView]; [self addSubview:m_label]; [self addSubview:m_closeButton]; self.backgroundColor = [UIColor clearColor]; } return self; } Any ideas?

  • How can I display the camera view in the main window in real time?

    - by Mongrel Warfare
    I'm trying to make an augmented reality application with a waypoint structure, like Yelp, and I'm wondering how to set up my main view so that it displays the camera view on the whole screen. I've heard of using the UIImagePickerController Class, but I'm unsure how to manipulate the code so that it doesn't actually take a picture, but just stays in the view mode. Any help would be appreciated, thanks!

    When I play a video with MPMoviePlayerController in my app my iPhone does not auto lock (tested OS 3.0 & 3.1.2). However, the application.idleTimerDisabled = NO, so this setting is not affected by MPMoviePlayerController. How can I get my iPhone to sleep normally (e.g. after 3 min screen dims, then goes dark) when my app is running and playing a video?
