    - by Thijs
    I've got a little problem. I am applying some changes to an iOS program i wrote, but I've struck a problem. I constantly get a "Expected '{' before ')' token" warning, but my coding skills aren't good enough to find the problem. A little help would greatly be appreciated. #import "Search.h" #import "RootViewController.h" //button - (IBAction)buttonPressed)sender{ RootViewController *newview = [[RootViewController alloc] initWithNibName:@"RootViewController" bundle:nil]; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; [UIView setAnimationTransition:UIViewAnimationTransitionFl ipFromRight forView:self.view cache:YES]; [self.view addSubview:newview.view]; [UIView commitAnimations]; @implementation Search @end

  • How to make a derived UITableVIew work

    - by justinhj
    I've made a new class in my Xcode project which is derived from UITableView I then drag a UITableView from in the interface builder onto my view and change the class of the object to my derived class. Then I drag the outlet from the table to the files owner and hook it up to an outlet variable in my main view, which is of the same type as my derived class. How do I also set up the datasource and delegate so that they belong to the derived class?

  • UITableView cell animate background

    - by psychotik
    I have a UITableView with a bunch of rows. When some action occurs, I want to animate the background of a cell. I just want to make it grey and then fade it back to the default in .5 seconds. Is my only option to set the background and call [tableView beginUpdates] followed by [tableView endUpdates] and then set a timer to clear the background again, or is there some more fundamental animation technique I can use here?

  • Why is Core Data not persisting these changes to disk?

    - by scott
    I added a new entity to my model and it loads fine but no changes made in memory get persisted to disk. My values set on the car object work fine in memory but aren't getting persisted to disk on hitting the home button (in simulator). I am using almost exactly the same code on another entity in my application and its values persist to disk fine (core data - sqlite3); Does anyone have a clue what I'm overlooking here? Car is the managed object, cars in an NSMutableArray of car objects and Car is the entity and Visible is the attribute on the entity which I am trying to set. Thanks for you assistance. Scott - (void)viewDidLoad { myAppDelegate* appDelegate = (myAppDelegate*)[[UIApplication sharedApplication] delegate]; NSManagedObjectContext* managedObjectContex = appDelegate.managedObjectContext; NSFetchRequest* request = [[NSFetchRequest alloc] init]; NSEntityDescription* entity = [NSEntityDescription entityForName:@"Car" inManagedObjectContext:managedObjectContex]; [request setEntity:entity]; NSSortDescriptor* sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"Name" ascending:YES]; NSArray* sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; [sortDescriptors release]; [sortDescriptor release]; NSError* error = nil; cars = [[managedObjectContex executeFetchRequest:request error:&error] mutableCopy]; if (cars == nil) { NSLog(@"Can't load the Cars data!

  • xPath Groupings how?

    - by David
    OK So, I'm learning/using xpath for a basic application thats effectively ripping data off another website. I need to gain the knowledge of each persons Countryy/Suburb/area. In some instances you can get Australia/Victoria/melborne for instance. Others may just be Australia/Melbourne. Or even just Melbourne OR just AUSTRALIA. who knows. So I'm current able to view the below code and rip all of the information with the string xpath search:@" //table/tr/td/tabke/tr/td/font/a, this returns every entry, but what I really want is to group each lot separately. I hope someone out there on planet earth knows what I just tried to explain... and can help... Good day! <font face="arial" size="2"> <strong>Location:</strong> <a href="http://maps.google.com/maps?q=Australia" target="mapblast" style="text-decoration:none">Australia</a>, <a href='http://maps.google.com/maps?q=Australia%20Victoria'target="mapblast" style='text-decoration:none'>Victoria</a>, <a href='http://maps.google.com/maps?q=Australia%20Melbourne%20Victoria'target="mapblast" style='text-decoration:none'>Melbourne</a> </font> </td> </tr>

  • Core Data and Relationships

    - by alku83
    I have two objects, a Trip and a Place. A Trip represents a journey from one Place to another Place, ie. a Trip needs a fromPlace and a toPlace. So, this is a 1-to-2 relationship, but I need to know which is the "from" and which is the "to". I am not sure how to model this in Core Data. I have created two entities (Trip, Place), and now I want to setup the relationship(s) so I have a fromPlace and a toPlace. Do I need to add an extra field on the Place entity called isFrom, or similar? If this was in a database, I would just have a id column on the Place table, and then two columns in the Trip table - fromPlaceId and toPlaceId. How do I achieve something similar in Core Data?

  • Why my buttons OnClick event fails to fire?

    - by Pentium10
    I have an activity, where the ListView holds customized linear layout elements for each row. One of the rows has a button defined as: <Button android:text="Pick a contact" android:id="@+id/btnPickContact" android:layout_width="wrap_content" android:gravity="center_vertical" android:layout_height="wrap_content"></Button> Then in java, I have this code: ((Button) row.findViewById(R.id.btnPickContact)).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); intent.putExtra(EXTRA_ONLINE_ID, (String)v.getTag(TAG_ONLINE_ID)); act.startActivityForResult(intent, PICK_CONTACT); } }); In this setup the event fails to start. Also I've tried by implementing the interface: @Override public void onClick(View v) { Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); intent.putExtra(EXTRA_ONLINE_ID, (String)v.getTag(TAG_ONLINE_ID)); startActivityForResult(intent, PICK_CONTACT); } still no luck, the event doesn't fire. What to do?

  • CGContextDrawImage returning bad access

    - by Marcelo
    Hello guys, I've been trying to blend two UIImage for about 2 days now and I've been getting some BAD_ACCESS errors. First of all, I have two images that have the same orientation, basically I'm using the CoreGraphics to do the blending. One curious detail, everytime I modify the code, the first time I compile and run it on device, I get to do everything I want without any sort of trouble. Once I restart the application, I get error and the program shuts down. Can anyone give me a light? I tried accessing the baseImage sizes dynamically, but it gives me bad access too. Here's a snippet of how I'm doing the blending. UIGraphicsBeginImageContext(CGSizeMake(320, 480)); CGContextRef context = UIGraphicsGetCurrentContext(); CGContextTranslateCTM(context, 0, 480); CGContextScaleCTM(context, 1.0, -1.0); CGContextDrawImage(context, rect, [baseImage CGImage]); CGContextSetBlendMode(context, kCGBlendModeOverlay); CGContextDrawImage(context, rect, [tmpImage CGImage]); [transformationView setImage:UIGraphicsGetImageFromCurrentImageContext()]; UIGraphicsEndImageContext();

  • Pinterest Gridview implementation on iOS

    - by Amal
    I want to implement a grid view like the one in Pinterest I thought about implementing as 3 table views. But I was not able to scroll them together well. When I implemented the scrollViewDidScroll and set the contentOffset for the table views other the scrollView , the scrolling became slow and unusable. Another implementation I did was of was having a set of images to load and calling the viewDraw function in scrollViewDidScroll. THe ViewDraw function just draws the necessary images and removes the rest of the images from the memory which were already drawn but wont be visible . this too makes the ScrollView Scrolling slow. And another issue with it is that there are white(background color) patches before the images are drawn. What should be the best way to implement this grid view ?

  • Public class: The best way to store and access NSMutableDictionary?

    - by meridimus
    I have a class to help me store persistent data across sessions. The problem is I want to store a running sample of the property list or "plist" file in an NSMutableArray throughout the instance of the Persistance class so I can read and edit the values and write them back when I need to. The problem is, as the methods are publicly defined I cannot seem to access the declared NSMutableDictionary without errors. The particular error I get on compilation is: warning: 'Persistence' may not respond to '+saveData' So it kind of renders my entire process unusable until I work out this problem. Here is my full persistence class (please note, it's unfinished so it's just to show this problem): Persistence.h #import <UIKit/UIKit.h> #define kSaveFilename @"saveData.plist" @interface Persistence : NSObject { NSMutableDictionary *saveData; } @property (nonatomic, retain) NSMutableDictionary *saveData; + (NSString *)dataFilePath; + (NSDictionary *)getSaveWithCampaign:(NSUInteger)campaign andLevel:(NSUInteger)level; + (void)writeSaveWithCampaign:(NSUInteger)campaign andLevel:(NSUInteger)level withData:(NSDictionary *)saveData; + (NSString *)makeCampaign:(NSUInteger)campaign andLevelKey:(NSUInteger)level; @end Persistence.m #import "Persistence.h" @implementation Persistence @synthesize saveData; + (NSString *)dataFilePath { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; return [documentsDirectory stringByAppendingPathComponent:kSaveFilename]; } + (NSDictionary *)getSaveWithCampaign:(NSUInteger)campaign andLevel:(NSUInteger)level { NSString *filePath = [self dataFilePath]; if([[NSFileManager defaultManager] fileExistsAtPath:filePath]) { NSLog(@"File found"); [[self saveData] setDictionary:[[NSDictionary alloc] initWithContentsOfFile:filePath]]; // This is where the warning "warning: 'Persistence' may not respond to '+saveData'" occurs NSString *campaignAndLevelKey = [self makeCampaign:campaign andLevelKey:level]; NSDictionary *campaignAndLevelData = [[self saveData] objectForKey:campaignAndLevelKey]; return campaignAndLevelData; } else { return nil; } } + (void)writeSaveWithCampaign:(NSUInteger)campaign andLevel:(NSUInteger)level withData:(NSDictionary *)saveData { NSString *campaignAndLevelKey = [self makeCampaign:campaign andLevelKey:level]; NSDictionary *saveDataWithKey = [[NSDictionary alloc] initWithObjectsAndKeys:saveData, campaignAndLevelKey, nil]; //[campaignAndLevelKey release]; [saveDataWithKey writeToFile:[self dataFilePath] atomically:YES]; } + (NSString *)makeCampaign:(NSUInteger)campaign andLevelKey:(NSUInteger)level { return [[NSString stringWithFormat:@"%d - ", campaign+1] stringByAppendingString:[NSString stringWithFormat:@"%d", level+1]]; } @end I call this class like any other, by including the header file in my desired location: @import "Persistence.h" Then I call the function itself like so: NSDictionary *tempSaveData = [[NSDictionary alloc] [Persistence getSaveWithCampaign:currentCampaign andLevel:currentLevel]];

    - by dythffvrb
    This is my code: $loginUrl = $facebook->getLoginUrl(array( 'scope' => 'publish_actions', 'redirect_uri' => 'http://mysite.com/', )); It works but if I remove redirect_uri it doesn't work anymore. $loginUrl = $facebook->getLoginUrl(array( 'scope' => 'publish_actions' )); According to Facebook domcumentation redirect_uri is optional. https://developers.facebook.com/docs/reference/php/facebook-getLoginUrl/ Im trying to redirect the users to the same url they were on before logging in. Update: This problem occurs when the url is mysite.com/post23 but when url is mysite.com/staticpage or mysite.com there are no problems Any workarounds? EDIT: It looks like a bug, it doesn't work with certain url in the same site I wil try and report it to Facebook.
