  • iPhone rotation woes

    - by skooter500
    I have been spending many frustrating hours trying to get rotations working on the iPhone version of Tunepal. Firstly, I have a tab bar controller, with a navigation controller controlling each of the views. I actually only want one of my views to be able to rotate and that is the TuneDisplay. I have a subclassed the UITabBarController and overridden theshouldAutorotateToInterfaceOrientation: (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation) interfaceOrientation { if (self.selectedViewController != nil) { return [self.selectedViewController shouldAutorotateToInterfaceOrientation:interfaceOrientation]; } else { return (interfaceOrientation == UIInterfaceOrientationPortrait); } } In each of the view controllers for each of the tabs I have overridden the method and returned YES for each orientation I want to support. All well and good and everything works as it should. If I try and do a rotation on a tab that doesn’t support the rotation, nothing happens. The problem occurs if I move from a tab thats rotated to a tab that isnt supposed to support that rotation. The new tab is displayed rotated too! Screenshots for all this are included here: http://tunepal.wordpress.com/2010/04/20/rotation-woes/ Is there any way I can make it rotate back to portrait on tapping the tab? I have tried the unsupported setOrientation trick, but firstly it doesnt work correctly and secondly I received a warning from Apple for including it in my last build. If (as I suspect) there is no way to limit this behavior: How do I make the microphone image scale when I rotate the device? How do I make the buttons and the progress bar expand to fit the witdh of the toolbar? Also, one of the tabs that rotates ok has a table, with a search bar. The first time I rotate to the right or to the left, I get a black bar to the right of the search bar. If I subsequently rotate back and rotate again, the bar disappears! I have enabled the struts and springs things on the search bar in the interface builder and it looks like it should behave correctly. Any ideas about how to fix this? Ideas, feedback much appreciated Bryan

  • Creation of model in core data on the fly

    - by user1740045
    How can we create a model in core data on the fly? I.e getting the schema of database from somewhere and then creating a Core Data Object graph? *QuesTion:* Yes thats fine, agreed with all the advantages. But, can anybody can tell practically, what is the benefit of integrating Core Data into project instead of using SQL directly. 1.No need to write SQL boiler plate code [but need to learn Core Data Model (steep curve)] 2.WE can undo and redo changes [but practically who needs it] 3.we can migrate to another schema [that can be done by SQLite as well jus need to add another field into table] 4.For say aggregation on some field in table,in Core Data we need to loop through Core Data Objects whereas in SQLite we need to first write SQLite Boiler Plate Code and then the basic aggregation SQL query,which is easy to write,only length of code will increase...But in case of Core Data (need to learn a lot). So apart from reducing the length of Code,does it actually adds value to project? or in terms of Memory Efficiency,Performance,etc.. PS: If anybody has actualy worked on Core Data(Model Creation On the Fly) , if possible share and gve pointers..thanks!

  • Using iPhone Core Data to many Relationship

    - by BLeB
    When I define a to many relationship between entities in Xcode and then generate the data class from the entity I get a header with the following methods defined: @interface PriceList (CoreDataGeneratedAccessors) - (void)addItemsObject:(PriceListItem *)value; - (void)removeItemsObject:(PriceListItem *)value; - (void)addItems:(NSSet *)value; - (void)removeItems:(NSSet *)value; @end When I attempt to call addItemsObject with the following code a doesNotRecognizeSelector exception is thrown. PriceListItem *item = [NSEntityDescription insertNewObjectForEntityForName:@"PriceListItem" inManagedObjectContext:managedObjectContext]; item.cat = [attributeDict valueForKey:@"c"]; item.sel = [attributeDict valueForKey:@"s"]; [self addItemsObject:item]; From what I have read I do not have to implement these methods and that they are generated at runtime. Any ideas?

Or is there another framework that people use to access MySQL ?

  • How to determine, upon launch, whether the app crashed the last time it quit?

    - by enchilada
    One of the crash reporter frameworks I've found does it like this: If there exist crash reports in the ~/Library/Logs/CrashReporter folder for the app, it determines that a crash occurred before. Then it allows the user to send the developer the crash log. And the finally, it deletes those logs. It is this deletion that is bothering me. It's not acceptable to me. Maybe the user wants to look at those logs later. It is simply rude to the user to just delete his crash logs. So I'm looking for a better way to determine the crash. It doesn't really work to store the last read crash logs in the user defaults or the user data, because that would mean that if the user deletes the data and defaults (which he has a right to do whenever he or she wishes), and then launches the app, it will be detected as crashed the last time it was quit. So this doesn't work. Any ideas?

  • Passing a pointer to an array to glGenBuffers

    - by Josh Elsasser
    I'm currently passing an array to a function, then attempting to use glGenBuffers with the array that is passed to the function. I can't figure out a way to get glGenBuffers to work with the array that I've passed. I have a decent grasp of the basics of pointers, but this is beyond me. This is basically how the render code works. It's a bit more complex, (colours using the same array idea, also not working) but the basic idea is as follows: void drawFoo(const GLfloat *renderArray, GLuint verticeBuffer) { glBindBuffer(GL_ARRAY_BUFFER, verticeBuffer); glBufferData(GL_ARRAY_BUFFER, sizeof(verticeBuffer)*sizeof(GLfloat), verticeBuffer, GL_STATIC_DRAW); glVertexPointer(2, GL_FLOAT, 0, 0); glEnableClientState(GL_VERTEX_BUFFER); glDrawArrays(GL_TRIANGLE_FAN, 0, 45); glDisableClientState(GL_VERTEX_BUFFEr); } Thanks in advance for the help

  • Why won't my movie play using MPMoviePlayerController?

    - by Nosrettap
    I'm trying to get a basic movie to play in an iPhone app; however, I can't seem to get it to work. Here's my entire code: #import <MediaPlayer/MediaPlayer.h> #import "ViewController.h" @implementation ViewController - (IBAction)playMoviePressed:(id)sender { NSURL *url = [NSURL URLWithString:@"http://www.ebookfrenzy.com/ios_book/movie/movie.mov"]; MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayer]; moviePlayer.controlStyle = MPMovieControlStyleDefault; moviePlayer.shouldAutoplay = YES; [self.view addSubview:moviePlayer.view]; [moviePlayer setFullscreen:YES animated:YES]; [moviePlayer prepareToPlay]; [moviePlayer play]; } @end I have one button on screen that calls playMoviePressed when it is tapped. I know that this method is getting called. I have also tried this with .mov and .mp4 local files that I have dragged into xcode.

  • when i set property(retain), one "self" = one "retain"?

    - by Walter
    although I'm about to finish my first app, I'm still confused about the very basic memory management..I've read through many posts here and apple document, but I'm still puzzled.. For example..I'm currently doing things like this to add a label programmatically: @property (retain, nonatomic) UILabel *showTime; @sythesize showTime; showTime = [[UILabel alloc] initWithFrame:CGRectMake(45, 4, 200, 36)]; [self.showTime setText:[NSString stringWithFormat:@"%d", time]]; [self.showTime setFont:[UIFont fontWithName:@"HelveticaRoundedLT-Bold" size:23]]; [self.showTime setTextColor:numColor]; self.showTime.backgroundColor = [UIColor clearColor]; [self addSubview:self.showTime]; [showTime release]; this is my current practice, for UILabel, UIButton, UIImageView, etc... [Alloc init] it without self., coz I know this will retain twice.. but after the allocation, I put back the "self." to set the attributes.. My gut feel tells me I am doing wrong, but it works superficially and I found no memory leak in analyze and instruments.. can anyone give my advice? when I use "self." to set text and set background color, does it retain one automatically? THX so much!

  • best way to use CoreLocation across multiple views

    - by Matt
    I have two views in my app, one is a general view where CoreLocation works away calculating the users location while the user is doing other stuff in the view. The second view is accessed by the user when they touch a button allowing them to locate themselves more accurately using a mapview and MapKit, i would like the mapview in this view to show the location that CoreLocation has already identified in the first view AND to continue displaying this location based on updates from CoreLocation in the other view. Is the best way here to create a singleton that encapsulates the CoreLocation stuff and have this referenced in the view with the map, or to use notifications ? or to use some other better practice for my scenario ? Thanks

  • iPad search bar bad memory access?

    - by Geoff Baum
    Hello all, So I am trying to implement a search bar in my app and am very close but can't seem to figure out where this memory error is occurring. This is what part of my search method looks like: filters = [[NSMutableArray alloc] init]; NSString *searchText = detailSearch.text; NSMutableArray *searchArray = [[NSMutableArray alloc] init]; // Normally holds the object (ex: 70 locations) searchArray = self.copyOfFilters ; //This is the line that is breaking after ~2-3 letters are entered in the search for (NSString *sTemp in searchArray) { NSRange titleResultsRange = [sTemp rangeOfString:searchText options:NSCaseInsensitiveSearch]; if (titleResultsRange.length > 0) [filters addObject:sTemp]; } displayedFilters = filters; copyOfFilters is a deep copy of the displayed filters that appear when the view first loads via: self.copyOfFilters = [[NSMutableArray alloc] initWithArray:displayedFilters copyItems:YES]; I have traced through the entry of letters and it is accurate after 2 letters, but once you try and enter a letter after a space in the search bar, it crashes. The value of copyOfFilters = {(int)[$VAR count]} objects. Does anyone know what may be causing this? Thanks!

  • Get current location using CLLocationCoordinate2D

    - by Mobility
    I am trying to get current location of user using CLLocationCoordinate2D. I want the values in the format like CLLocationCoordinate2D start = {-28.078694,153.382844 }; So that I can use them like following: NSString *urlAddress = [NSString stringWithFormat:@"http://maps.google.com/?saddr=%1.6f,%1.6f&daddr=%1.6f,%1.6f", start.latitude, start.longitude, destination.latitude, destination.longitude]; I used CLLocation *location = [[CLLocation alloc]init ]; CLLocationDegrees currentLatitude = location.coordinate.latitude; CLLocationDegrees currentLongitude = location.coordinate.longitude; to get current lat & long. But I am getting 0.000 for both when I try to test. I am testing on iPhone 4s. If there is any sample code, it will be great.

  • How to access property in sub method after it runs?

    - by Warren
    I'm having a hard time working this one out but I think it should be pretty simple. Basically, I have this method which talks to a webservice and I need to return some data from the sub method, the "authCode". What am I doing wrong? How can I get the authCode out of the manager, or can I create a block or something to to ensure that the manager block runs first? Am I even using the right words - blocks, sub methods??? Please help :) - (NSString *)getAuthCodeEXAMPLE { __block NSString *returnString = @"nothing yet!"; NSURL *baseURL = [NSURL URLWithString:BaseURLString]; NSDictionary *parametersGetAuthCode = @{@"req": @"getauth"}; AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:baseURL]; manager.responseSerializer = [AFJSONResponseSerializer serializer]; [manager POST:APIscript parameters:parametersGetAuthCode success:^(NSURLSessionDataTask *task, id responseObject) { if ([task.response isKindOfClass:[NSHTTPURLResponse class]]) { NSHTTPURLResponse *r = (NSHTTPURLResponse *)task.response; if ([r statusCode] == 200) { self.returnedData = responseObject; NSString *authCode = [self.returnedData authcode]; NSLog(@"Authcode: %@", authCode); returnString = authCode; } } } failure:^(NSURLSessionDataTask *task, NSError *error) { UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error" message:[error localizedDescription] delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alertView show]; }]; //this currently returns "nothing yet!" return returnString; }

  • iPad --- managedObject problem when [self.tableViewSection reloadData]

    - by user345777
    Hi , I am creating a news aggregator application that fetches a xml feed every 4 minutes. After the xml is loaded, I clear everything by deleting all the objects in the database, then save the new objects back into the database. I then call [self.tableViewSection reloadData]; to reload the tableView. Thats when I get a problem. As soon as the code gets to a section where i access the new [[managedObject valueForKey:@"event_text"] description] content it fails with a : * Terminating app due to uncaught exception 'NSObjectInaccessibleException', reason: 'CoreData could not fulfill a fault for '0x4b3f6a0 '' Now from the flow I described on top, it seems odd to me that the tableView is populated properly the next time i launch the application, with the "new" data I fetched in the previous session. So its not that data thats corrupt , but seems to me something goes wrong when I refetch the managedObject after saving new data. Also keep in mind thats this app runs fine on the iPhone, its the iPad thats is giving me this problem.
