  • Exposing headers on iPhone static library

    - by leolobato
    Hello guys, I've followed this tutorial for setting up a static library with common classes from 3 projects we are working on. It's pretty simple, create a new static library project on xcode, add the code there, a change some headers role from project to public. The tutorial says I should add my library folder to the header search paths recursively. Is this the right way to go? I mean, on my library project, I have files separated in folders like Global/, InfoScreen/, Additions/. I was trying to setup one LOKit.h file on the root folder, and inside that file #import everything I need to expose. So on my host project I don't need to add the folder recursively to the header search path, and would just #import "LOKit.h". But I couldn't get this to work, the host project won't build complaining about all the classes I didn't add to LOKit.h, even though the library project builds. So, my question is, what is the right way of exposing header files when I setup a Cocoa Touch Static Library project on xCode?

  • iphone - UIViewController header view errors

    - by Fiona
    Hi there, So to give a little background: I've an app that has a UITableViewController- (ContactDetailViewController) In this view at the top, I require a few labels and buttons, followed by a group style tableview. So I've created a nib file containing these elements. (ContactHeaderView.xib) Then in the viewDidLoad of ContactDetailViewController I've loaded this nib as the headerView. See implementation file below: #import "ContactDetailViewController.h" #import "DisplayInfoViewController.h" #import "ActionViewController.h" @implementation ContactDetailViewController @synthesize name; @synthesize date; @synthesize nextAction; @synthesize nameLabel; @synthesize usernameLabel; @synthesize nextActionTextField; @synthesize dateLabel; @synthesize contactInfoButton; @synthesize backgroundInfoButton; @synthesize actionDoneButton; - (void)viewDidLoad { [super viewDidLoad]; } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; // Release any cached data, images, etc that aren't in use. } - (void)viewDidUnload { // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } #pragma mark Table view methods - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } // Customize the number of rows in the table view. - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 3; } - (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section { if (section == 0){ UIViewController *chv = [[[UIViewController alloc] initWithNibName:@"ContactHeaderView" bundle:nil] autorelease]; // self.nameLabel.text = self.name; return chv.view; }else{ return nil; } } - (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section{ return 300.0; } // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } // Set up the cell... return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here. Create and push another view controller. // AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@"AnotherView" bundle:nil]; // [self.navigationController pushViewController:anotherViewController]; // [anotherViewController release]; } /* // Override to support conditional editing of the table view. - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath { // Return NO if you do not want the specified item to be editable. return YES; } */ - (void)dealloc { [name release]; [date release]; [nextAction release]; [nameLabel release]; [usernameLabel release]; [nextActionTextField release]; [dateLabel release]; [contactInfoButton release]; [backgroundInfoButton release]; [actionDoneButton release]; [super dealloc]; } -(IBAction)displayContactInfo:(id)sender{ DisplayInfoViewController *divc = [[DisplayInfoViewController alloc] init]; divc.textView = self.nextAction; divc.title = @"Contact Info"; [self.navigationController pushViewController:divc animated:YES]; [divc release]; } -(IBAction)displayBackgroundInfo:(id)sender{ DisplayInfoViewController *divc = [[DisplayInfoViewController alloc] init]; divc.textView = self.nextAction; divc.title = @"Background Info"; [self.navigationController pushViewController:divc animated:YES]; [divc release]; } -(IBAction)actionDone:(id)sender{ ActionViewController *avc = [[ActionViewController alloc] init]; avc.title = @"Action"; avc.nextAction = self.nextAction; [self.navigationController pushViewController:avc animated:YES]; [avc release]; } @end Here's the Header File: #import <UIKit/UIKit.h> @interface ContactDetailViewController : UITableViewController { NSString *name; NSString *date; NSString *nextAction; IBOutlet UILabel *nameLabel; IBOutlet UILabel *usernameLabel; IBOutlet UITextField *nextActionTextField; IBOutlet UILabel *dateLabel; IBOutlet UIButton *contactInfoButton; IBOutlet UIButton *backgroundInfoButton; IBOutlet UIButton *actionDoneButton; } @property (nonatomic, retain) NSString *name; @property (nonatomic, retain) NSString *date; @property (nonatomic, retain) NSString *nextAction; @property (nonatomic, retain) IBOutlet UILabel *nameLabel; @property (nonatomic, retain) IBOutlet UILabel *usernameLabel; @property (nonatomic, retain) IBOutlet UITextField *nextActionTextField; @property (nonatomic, retain) IBOutlet UILabel *dateLabel; @property (nonatomic, retain) IBOutlet UIButton *contactInfoButton; @property (nonatomic, retain) IBOutlet UIButton *backgroundInfoButton; @property (nonatomic, retain) IBOutlet UIButton *actionDoneButton; -(IBAction)displayContactInfo: (id)sender; -(IBAction)displayBackgroundInfo: (id)sender; -(IBAction)actionDone: (id)sender; @end However when I run it, I get the following error message: * Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key nameLabel.' In IB I've hooked up the labels/buttons/textbox to the File's Owner (set the File's Owner Class to: ContactDetailViewController) Anyone any idea what I'm doing wrong? Regards, Fiona

  • Pre-crash iphone symptoms - odd user position, volume change

    - by BankStrong
    I'm seeing intermittent strange symtoms in my app: Blue blob (user position in MKMapView) starts "exploding" (odd, jerky animation). Can begin at startup and seems to indicate eventual problems. Speaker volume suddenly increases (back to level before I invoked kAudioSessionSetProperty_OtherMixableAudioShouldDuck). The app keeps running, but this change tells me to expect no more sounds from AVAudioPlayer. Also a reliable indicator of a future crash (on save, etc). I'm having trouble provoking this in the debugger (seems to only happen with movement in GPS). Any ideas to track it down?

  • willSendRequest redirectResponse doesn't work in iPhone SDK2.0

    - by WholeIphone
    I use the delegate method connection:willSendRequest:redirectResponse: in SDK 2.2, the code like below: - (NSURLRequest *)connection:(NSURLConnection *)con willSendRequest:(NSURLRequest *)request redirectResponse:(NSURLResponse *)redirectResponse { if(redirectResponse) { if(!self.autoRedirect) { NSLog(@"response will redirect"); request = nil; } } return request; if the request is returned to nil ,it seems it hangs up here, and delegate didReceiveData will not get called. but it works in SDK 3. Any suggestions about this?

  • [iPhone] UIScrollView notifications

    - by ryyst
    Hi, I'm coding an app that works much like Apple's Weather.app: There's a UIPageControl at the bottom and a UIScrollView in the middle of the screen. In my code, I implemented the - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView method to figure out when the user did move to a new page. If they move to a new page, I load the adjacent pages' data, as to make further page-switching faster. (In one of Apple's examples, the - (void)scrollViewDidScroll:(UIScrollView *)sender is used, but that causes my app to shortly hang when loading a new page, so it's not suitable.) That code works very well. I'm using scrollRectToVisible:: to programmatically scroll inside the scrollview when the user clicks the UIPageControl. The problem is that the scrollRectToVisible: doesn't post a notification to the UIScrollViewDelegate when it's done scrolling - so the code responsible for loading adjacent pages never get's called when using the UIPageControl. Is there any way to make the UIScrollView notify its delegate when it gets called by the scrollRectToVisible: method? Or will I have to use threads in order to prevent my app from freezing? Thanks! -- Ry

  • iPhone SDK - CGBitmapContextCreate

    - by nax_
    Hi, I would like to create an image of my own. I already know its width (320*2 = 640) and height (427). So I have some raw data : unsigned char *rawImg = malloc(height * width * 4 *2 ); Then, I will fill it :) Then, I have to do something like that to get a bitmap and return a (UIImage *) : ctx = CGBitmapContextCreate(rawImg,width*2,height,8, ???, ???, kCGImageAlphaPremultipliedLast); UIImage * imgFinal = [UIImage imageWithCGImage:CGBitmapContextCreateImage(ctx)]; CGContextRelease(ctx); return imgFinal; But I don't know how to create my context ctx, as you can see with the "???", even tough I read the documentation... Please help ! Thanks :)

  • iPhone reachability checking

    - by Sneakyness
    I've found several examples of code to do what I want (check for reachability), but none of it seems to be exact enough to be of use to me. I can't figure out why this doesn't want to play nice. I have the reachability.h/m in my project, I'm doing #import <SystemConfiguration/SystemConfiguration.h> And I have the framework added. I also have: #import "Reachability.h" at the top of the .m in which I'm trying to use the reachability. Reachability* reachability = [Reachability sharedReachability]; [reachability setHostName:@"http://www.google.com"]; // set your host name here NetworkStatus remoteHostStatus = [reachability remoteHostStatus]; if(remoteHostStatus == NotReachable) {NSLog(@"no");} else if (remoteHostStatus == ReachableViaWiFiNetwork) {NSLog(@"wifi"); } else if (remoteHostStatus == ReachableViaCarrierDataNetwork) {NSLog(@"cell"); } This is giving me all sorts of problems. What am I doing wrong? I'm an alright coder, I just have a hard time when it comes time to figure out what needs to be put where to enable what I want to do, regardless if I want to know what I want to do or not. (So frustrating) Update: This is what's going on. This is in my viewcontroller, which I have the #import <SystemConfiguration/SystemConfiguration.h> and #import "Reachability.h" set up with. This is my least favorite part of programming by far. FWIW, we never ended up implementing this in our code. The two features that required internet access (entering the sweepstakes, and buying the dvd), were not main features. Nothing else required internet access. Instead of adding more code, we just set the background of both internet views to a notice telling the users they must be connected to the internet to use this feature. It was in theme with the rest of the application's interface, and was done well/tastefully. They said nothing about it during the approval process, however we did get a personal phone call to verify that we were giving away items that actually pertained to the movie. According to their usually vague agreement, you aren't allowed to have sweepstakes otherwise. I would also think this adheres more strictly to their "only use things if you absolutely need them" ideaology as well. Here's the iTunes link to the application, EvoScanner.

  • iPhone UIScrollView embedded UIView is clipped

    - by scc
    Hello. I have an iPad UIView subclass (we'll call LargerUIView) with which I do a bunch of drawing via drawRect: once asked. That all appears to be working, and looks the way I like. I'm at the point now of trying to get scrolling working (just in the horizontal to begin), yet when I try to scroll, what shows below is black (ie, appears to have never been drawn). That doesn't surprise me as it's likely been clipped. Looking for suggestions. Here's what I'm doing so far: MyAppDelegate.m - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { CGRect scrollRect = CGRectMake(0, 0, 768, 1024); UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:scrollRect]; LargerUIView *view = (LargerUIView *)[viewController view]; [scrollView addSubview:view]; [scrollView setContentSize:CGSizeMake(768, pageHeight)]; [scrollView setContentMode:UIViewContentModeRedraw]; [scrollView setClipsToBounds:YES]; [window addSubview:scrollView]; [scrollView release]; // Without this next line, the "frontmost" (ie, most recently added subview) // is the MoxiesAppetizerMenu - which is not equipped to handle scrolling/UIEvents [window sendSubviewToBack:view]; // Show it all. [window makeKeyAndVisible]; return YES; } Any suggestions? Have tried changing "setClipsToBounds" to NO as well.

  • iPhone Core Data does not refresh table

    - by Brian515
    Hi all, I'm trying to write an application with Core Data, and I have been able to successfully read and write to the core data database. However, if I write to the database in one view controller, my other view controllers will not see the change until the app is closed then reopened again. This is really frustrating. I'm not entirely sure how to get the refresh - (void)refreshObject:(NSManagedObject *)object mergeChanges:(BOOL)flag method to work. How do I get a reference to my managed object? Anyways, here's the code I'm using to read the data back. This is in the viewDidLoad method. NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Website" inManagedObjectContext:managedObjectContext]; [request setEntity:entity]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"siteName" ascending:NO]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; [sortDescriptor release]; [sortDescriptors release]; NSError *error = nil; NSMutableArray *mutableFetchResults = [[managedObjectContext executeFetchRequest:request error:&error] mutableCopy]; if(mutableFetchResults == nil) { //Handle the error } [self setNewsTitlesArray:mutableFetchResults]; [mutableFetchResults release]; [request release]; [newsSourcesTableView reloadData]; Thanks for help in advance!

  • FBConnect stream.publish with iphone unknown response?

    - by Tom G
    Hi All, I am using stream.publish to publish some info to a users wall. This all works fine. I am not using FBStreamDialog because i do not want the user to be able to edit the message..... So i have set up my own UI. It all works fine and the stream is published to the users wall, the only issue is that i do not understand the result obtained from the delegate method: - (void)request:(FBRequest*)request didLoad:(id)result { NSLog(@"result = %@", result); } I need to understand what the result is telling me so that i can handle any errors. Currently the following is being printed in the console but i do not know what this means: result = 100000874992250_117813161591916 Any help or advice regarding this issue would be highly appreciated.

  • Addressing a memory leak stops my UI from showing iphone

    Hi I've being getting a memory leak warning with a UITabbarcontroller. If I release the tabbarcontroller the warning goes away but the tabbar will not show any content. If I debug the app with the warning still in it the app runs but will crash after a couple of minutes UITabBarController *tabBarController = [[UITabBarController alloc] init]; tabBarController.view.frame = CGRectMake(0, 0, 320, 460); tabBarController.viewControllers=localControllersArray; // Clean up objects we don't need anymore [promoTabOptionHome release]; [promoTabOptionInfo release]; [promoTabOptionEvents release]; [promoTabOptionBuy release]; [localControllersArray release]; // Finally, add the tab controller view to the parent view [self.view addSubview:tabBarController.view]; //[tabBarController release]; commenting out this line removes the warning but results in no content being shown

  • Import csv data (SDK iphone)

    - by Ni
    I am new to cocoa. I have been working on these stuff for a few days. For the following code, i can read all the data in the string, and successfully get the data for plot. NSMutableArray *contentArray = [NSMutableArray array]; NSString *filePath = @"995,995,995,995,995,995,995,995,1000,997,995,994,992,993,992,989,988,987,990,993,989"; NSArray *myText = [filePath componentsSeparatedByString:@","]; NSInteger idx; for (idx = 0; idx < myText.count; idx++) { NSString *data =[myText objectAtIndex:idx]; NSLog(@"%@", data); id x = [NSNumber numberWithFloat:0+idx*0.002777778]; id y = [NSDecimalNumber decimalNumberWithString:data]; [contentArray addObject: [NSMutableDictionary dictionaryWithObjectsAndKeys:x, @"x", y, @"y", nil]]; } self.dataForPlot = contentArray; then, i try to load the data from csv file. the data in Data.csv file has the same value and the same format as 995,995,995,995,995,995,995,995,1000,997,995,994,992,993,992,989,988,987,990,993,989. I run the code, it is supposed to give the same graph output. however, it seems that the data is not loaded from csv file successfully. i can not figure out what's wrong with my code. NSMutableArray *contentArray = [NSMutableArray array]; NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Data" ofType:@"csv"]; NSString *Data = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil ]; if (Data) { NSArray *myText = [Data componentsSeparatedByString:@","]; NSInteger idx; for (idx = 0; idx < myText.count; idx++) { NSString *data =[myText objectAtIndex:idx]; NSLog(@"%@", data); id x = [NSNumber numberWithFloat:0+idx*0.002777778]; id y = [NSDecimalNumber decimalNumberWithString:data]; [contentArray addObject: [NSMutableDictionary dictionaryWithObjectsAndKeys:x, @"x", y, @"y",nil]]; } self.dataForPlot = contentArray; } The only difference is NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Data" ofType:@"csv"]; NSString *Data = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil ]; if (data){ } did i do anything wrong here?? Thanks for your help!!!!
