  • EventKitUI view and edit problem!

    - by Alish
    I try to to find a solution to do View and Edit of a the item from a tablview. My application base on UITabBarController. Each of the Bar items contain a class with a a couple of UIViews. This is the first items of UITabBarController. I done Add event from Apple sample code: SimpleEKDemo. Add Event working without any problem. I tried to add View and Edit part to the code. I would able to select an items from tableView to edit the selected item. But after I tried to add code from SimpleEKDemo to my code, I realized I have to add UINavigationController to the implement. So I did. After I add that it's came to the items of UITabBarController. Also I even the Add Event didn't worked very well (I couldn't insert event name and location. but edit was working. So I need to know: 1- Is it possible to implement Edit/View without using UINavigationController. If yes please let me know a sample code. 2- If I must use UINavigationController. Because I don't need UINavigationController to become it the first page and I don't need any bar added to my application. Is it possible it's appear in the application when I choose a item of tableView but appear alike that! Snapshots: https://public.me.com/alish (pict.zip)

  • Int Showing as Long Odd Value

    - by Josh Kahane
    Hi I am trying to send an int in my iphone game for game center multiplayer. The integer is coming up and appearing as an odd long integer value rather than the expected one. I have this in my .h: typedef enum { kPacketTypeScore, } EPacketTypes; typedef struct { EPacketTypes type; size_t size; } SPacketInfo; typedef struct { SPacketInfo packetInfo; int score; } SScorePacket; Then .m: Sending data: scoreData *score = [scoreData sharedData]; SScorePacket packet; packet.packetInfo.type = kPacketTypeScore; packet.packetInfo.size = sizeof(SScorePacket); packet.score = score.score; NSData* dataToSend = [NSData dataWithBytes:&packet length:packet.packetInfo.size]; NSError *error; [self.myMatch sendDataToAllPlayers: dataToSend withDataMode: GKMatchSendDataUnreliable error:&error]; if (error != nil) { // handle the error } Receiving: SPacketInfo* packet = (SPacketInfo*)[data bytes]; switch (packet->type) { case kPacketTypeScore: { SScorePacket* scorePacket = (SScorePacket*)packet; scoreData *score = [scoreData sharedData]; [scoreLabel setString:[NSString stringWithFormat:@"You: %d Challenger: %d", score.score, scorePacket]]; break; } default: CCLOG(@"received unknown packet type %i (size: %u)", packet->type, packet->size); break; } Any ideas? Thanks.

  • Memory Leaks in pickerView using sqlite

    - by Danamo
    I'm adding self.notes array to a pickerView. This is how I'm setting the array: NSMutableArray *notesArray = [[NSMutableArray alloc] init]; [notesArray addObject:@"-"]; [notesArray addObjectsFromArray:[dbManager getTableValues:@"Notes"]]; self.notes = notesArray; [notesArray release]; The info for the pickerView is taken from the database in this method: -(NSMutableArray *)getTableValues:(NSString *)table { NSMutableArray *valuesArray = [[NSMutableArray alloc] init]; if (sqlite3_open([self.databasePath UTF8String], &database) != SQLITE_OK) { sqlite3_close(database); NSAssert(0, @"Failed to open database"); } else { NSString *query = [[NSString alloc] initWithFormat:@"SELECT value FROM %@", table]; sqlite3_stmt *statement; if (sqlite3_prepare_v2(database, [query UTF8String], -1, &statement, nil) == SQLITE_OK) { while (sqlite3_step(statement) == SQLITE_ROW) { NSString *value =[NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 0)]; [valuesArray addObject:value]; [value release]; } sqlite3_reset(statement); } [query release]; sqlite3_finalize(statement); sqlite3_close(database); } return valuesArray; } But I keep getting memory leaks in Instruments for these lines: NSMutableArray *valuesArray = [[NSMutableArray alloc] init]; and [valuesArray addObject:value]; What am I doing wrong here? Thanks for your help!

  • How do I get intellisense to pop up?

    - by TheLearner
    How do I get intellisense to pop up while I am coding? I know it pops up when I start typing a known type e.g.: if I type NSS it will finish it for me NSString. How do I get it to give me a bunch of options like in Visual Studio e.g.: if I type NS I want to see what my options are like NSString, NSInteger etc? And if I have not typed anything I still want a bunch of options like all the instance variables etc.

  • Keeping object in memory (iPhone SDK)

    - by Chris
    I am trying to create a UIImageView called theImageView in the touchesBegan method that I can then then move to a new location in touchesMoved. Currently I am receiving an "undeclared" error in touchesMoved where I set the new location for theImageView. What can I do to keep theImageView in memory between these two methods? - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { ... UIImageView *theImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"]]; theImageView.frame = CGRectMake(263, 228, 193, 300); [theImageView retain]; ... } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { ... theImageView.frame = CGRectMake(300, 300, 193, 300); ... }

  • Content Alignment Issue in UITableView cell

    - by OhhMee
    Please see the image attached. I don't understand why it's going outside. I've also attached code snippet for tableView. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]; // cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton; } // Configure the cell. hNode* dCell = [array objectAtIndex:[indexPath row]]; cell.textLabel.text = @"Message"; cell.detailTextLabel.text = [NSString stringWithFormat:@"%@",[dCell contents]]; cell.detailTextLabel.lineBreakMode = UILineBreakModeWordWrap; cell.detailTextLabel.numberOfLines = 0; [[cell imageView] setImage:[UIImage imageNamed:@"user.png"]]; return cell; } - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath*)indexPath { return 60; } Where could be the issue?

  • Would a pointer to a pointer to nil match against NULL?

    - by dontWatchMyProfile
    Example: A validation method contains this check to see if an NSError object shall be created or not: - (BOOL)validateCompanyName:(NSString *)newName error:(NSError **)outError { if (outError != NULL) { // do it... Now I pass an NSError object, like this: NSError *error = nil; BOOL ok = [self validateCompanyName:@"Apple" error:&error]; I'm not sure if this matches the check for not NULL. I think it's not NULL, since I believe NULL is not nil. Maybe someone can clear this up?

  • Problem with CFNetRegister

    - by xtrahotsauce
    I'm trying to work with CFNetServices by trying to start up and publish a service asynchronously. I'm trying to use the example code from here: http://developer.apple.com/mac/library/documentation/Networking/Conceptual/NSNetServiceProgGuide/Articles/CFNetServices.html#//apple_ref/doc/uid/30001276-SW3, but CFNetRegisterWithOptions always fails. (CFNetRegister is deprecated now). When I print out the error struct, it looks like this: (gdb) p error $1 = { domain = 10, error = -72004 } Which doesn't seem correct to me. Does anyone know what might be wrong? Thanks!

  • Button not moving on my interface

    - by user1500134
    First before I say anything I want to announce that i'm fairly new to this kind of stuff so don't get all super techie on me :D ! Ok so i'm making an app and i'm trying to get a button to move to certain coordinates depending on the screen size of the phone (4, 4S, 5, etc...). I have correct syntax but the button will not move at all. Here is the part of my .m ViewController file... - (void)viewDidLoad { if([[UIScreen mainScreen] respondsToSelector:NSSelectorFromString(@"scale")]) { if ([[UIScreen mainScreen] scale] < 1.1) { CGRect frame = done.frame; frame.origin.x = 129; //New x coordinate frame.origin.y = 401; //New y coordinate done.frame = frame; NSLog(@"Standard Resolution"); } if ([[UIScreen mainScreen] scale] > 1.9) { NSLog(@"High Defenition Resolution"); } } [super viewDidLoad]; // Do any additional setup after loading the view from its nib. } The NSLog is triggering int he console saying 'Standard Resolution'but the button doesn't move from where I placed it in the XIB file. This may be a small stupid mistake but hopefully you can help me anyways... Thanks guys! :) P.S. Yes I did link my IBOutlet to the button

  • UINavigationController's back button disappears?

    - by QAD
    I notice something strange happens to one of my view controller: the back button disappears, yet it's possible to go back to previous view controller by tapping the top left corner (i.e where the button should reside). In my entire file there's no line that set self.navigationItem.hidesBackButton to YES; also NSLog prints 0 as self.navigationItem.hidesBackButton's value in viewDidLoad. This occurs in both the simulator and real device. Any ideas?

    - by Jules
    I'm having some trouble using an NSUInteger, I've tried various things and googled, but not found the answer ? I have... I also tried ... nonatomic, retain @property (readwrite, assign) NSUInteger *anAmount; @synthesize anAmount; error: type of property 'anAmount' does not match type of ivar 'anAmount' Also when I release it in dealloc I get a warning.. warning: invalid receiver type 'NSUInteger'

  • Does this singleton pattern make sense?

    - by dontWatchMyProfile
    @implementation MySingletonClass static MySingletonClass *sharedInstance = nil; + (MySingletonClass*)sharedInstance { @synchronized(self) { if (sharedInstance == nil) { sharedInstance = [[self alloc] init]; } } return sharedInstance; } + (id)alloc { @synchronized(self) { if (sharedInstance == nil) { sharedInstance = [super alloc]; return sharedInstance; } } return nil; } + (id)allocWithZone:(NSZone *)zone { @synchronized(self) { if (sharedInstance == nil) { sharedInstance = [super allocWithZone:zone]; return sharedInstance; } } return nil; } -(id)init { self = [super init]; if (self != nil) { // initialize stuff here } return self; } @end Not sure if it's ok to overwrite both alloc and allocWithZone: like this...?

  • Animation with CGPoint in for loop

    - by user1066524
    I'm trying to do an animation where when a person clicks from point A to Point B on screen the object should slowly slide straight across (horizontally) from point A to Point B. I tried doing a for loop with something like: for (CGFloat i=previousPoint.x; i <= newPoint.x; i++){ [UIView animateWithDuration:10 delay:0 options:nil animations:^ { [magnifier removeFromSuperview]; magnifier = [[MagnifierView alloc] init]; CGPoint np = {i, newPoint.y}; magnifier.viewToMagnify = imageView; magnifier.touchPoint = np; [imageView addSubview:magnifier]; [magnifier setNeedsDisplay]; } completion:^(BOOL finished) { }]; } but for some reason it is moving it way up and then eventually to point B. sort of in a weird curve. how can I do this correctly?

  • How to login users that are stored within a Wordpress account

    - by user3716795
    I am developing an iOS app that is password protected and all the users are stored in a wordpress account that, of course, is password protected as well. Does anybody know the format that wordpress uses to store login information for these accounts, I would assume that it is a MySQL that sends a json? I have only been able to find the database code for the initial admin page but nothing that shows the way these accounts (815 to be exact) would be stored within the site.

  • Passing a NSString to another ViewController using classes

    - by Jeff Kranenburg
    I know this insanely simple, but I am re-teaching myself the basics and trying to get my head around this:-) I have one ViewController called MainVC and I have one called ClassVC In ClassVC I have this code: @interface ClassVC : UIViewController { NSString *mainLine; } @property (nonatomic, retain) NSString *mainLine; @end and I have this in the implementation file: @synthesize mainLine = _mainLine; -(NSString *)_mainLine { _mainLine = @"This a string from a Class"; return _mainLine; } Now I was thinking that if I #import the ClassVC into MainVC I would be able to transfer that string along as well like so: This code is in the viewDidLoad _mainLabel.text = _secondClass.mainLine; NSLog(@"%@", _secondClass.mainLine); But that is not working - so cannot I not pass strings in through this way???
