  • ObjC get property name

    - by Joe Even
    Yes. I've searched a lot without success. I've looking for a way to get a property name as StringValue from inside a method. Lets say: My class has X Subviews from the Type UILabel. @property (strong, nonatomic) UILabel *firstLabel; @property (strong, nonatomic) UILabel *secondLabel; [...] and so on. Inside the method foo, the views are iterated as followed: -(void) foo { for (UIView *view in self.subviews) { if( [view isKindOfClass:[UILabel class]] ) { /* codeblock that gets the property name. */ } } } The Result should be something like that: THE propertyName(NSString) OF view(UILabel) IS "firstLabel" I've tried class_getInstanceVariable, object_getIvar and property_getName without Success. For Example, the Code for: [...] property_getName((void*)&view) [...] RETURNS: <UILabel: 0x6b768c0; frame = (65 375; 219 21); text = 'Something'; clipsToBounds = YES; opaque = NO; autoresize = RM+BM; userInteractionEnabled = NO; layer = <CALayer: 0x6b76930>> But i'm looking for this kind of result: "firstLabel" , "secondLabel" and so on. Thanks for your help! Reagrds Joé

  • Get UITableView to scroll to the selected UITextField and Avoid Being Hidden by Keyboard

    - by Lauren Quantrell
    I have a UITextField in a table view on a UIViewController (not a UITableViewController). If the table view is on a UITableViewController, the table will automatically scroll to the textField being edited to prevent it from being hidden by the keyboard. But on a UIViewController it does not. I have tried for a couple of days reading through multiple ways to try to accomplish this and I cannot get it to work. The closest thing that actually scrolls is: -(void) textFieldDidBeginEditing:(UITextField *)textField { // SUPPOSEDLY Scroll to the current text field CGRect textFieldRect = [textField frame]; [self.wordsTableView scrollRectToVisible:textFieldRect animated:YES]; } However this only scrolls the table to the topmost row. What seems like an easy task has been a couple of days of frustration. I am using the following to construct the tableView cells: - (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSString *identifier = [NSString stringWithFormat: @"%d:%d", [indexPath indexAtPosition: 0], [indexPath indexAtPosition:1]]; UITableViewCell *cell = [aTableView dequeueReusableCellWithIdentifier:identifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier] autorelease]; cell.accessoryType = UITableViewCellAccessoryNone; UITextField *theTextField = [[UITextField alloc] initWithFrame:CGRectMake(180, 10, 130, 25)]; theTextField.adjustsFontSizeToFitWidth = YES; theTextField.textColor = [UIColor redColor]; theTextField.text = [textFieldArray objectAtIndex:indexPath.row]; theTextField.keyboardType = UIKeyboardTypeDefault; theTextField.returnKeyType = UIReturnKeyDone; theTextField.font = [UIFont boldSystemFontOfSize:14]; theTextField.backgroundColor = [UIColor whiteColor]; theTextField.autocorrectionType = UITextAutocorrectionTypeNo; theTextField.autocapitalizationType = UITextAutocapitalizationTypeNone; theTextField.clearsOnBeginEditing = NO; theTextField.textAlignment = UITextAlignmentLeft; //theTextField.tag = 0; theTextField.tag=indexPath.row; theTextField.delegate = self; theTextField.clearButtonMode = UITextFieldViewModeWhileEditing; [theTextField setEnabled: YES]; [cell addSubview:theTextField]; [theTextField release]; } return cell; } I suspect I can get the tableView to scroll properly if I can somehow pass the indexPath.row in the textFieldDidBeginEditing method? Any help is appreciated.

  • Facebook writing on a wall problem - retrieves only null value.

    - by Viral
    hi all friends, I am making a game application in that I want to pass my score on wall of face book. I've completed all the things (the log in and message passing part) but when I passes the score via global variable, I am getting only null as a value and not the score that I want. Is there any way to pass data or string to Face book and write on a wall? My code is (void)viewDidLoad { static NSString* kApiKey = @"be60415be308e2b44c0ac1db83fe486b"; static NSString* kApiSecret = @"4f880c7e100321f808c41b1d3c813dfa"; _session = [[FBSession sessionForApplication:kApiKey secret:kApiSecret delegate:self] retain]; score = [NSString stringWithFormat:@"%@",appDelegate.myTextView]; [_session resume]; [super viewDidLoad]; } whre score is NSString and myTextView is NSString in other viewcontrollerfile, And appDelegate is global variable. Any help?? thanks in advance.

  • Debugging over-released objects, problem with NSZombie

    - by hyn
    I have a reproduceable EXC_BAD_ACCESS during NSAutoreleasePool -drain, which seems to indicate that I am over-releasing an object. So I enable NSZombie, but then the program does not crash any more. Nor do I get any info logged to the console. If I turn NSZombie off, the crash comes back. What is the meaning of this? I thought NSZombies were used to tackle exactly this kind of problem. If NSZombie won't help, is there another way to interrogate this over-released object? Also the crash is not reproduceable on Simulator, which is why I can't use Instruments with NSZombie.

  • Migrating from a single entity to an abstract parent entity with child entities, NSEntityMigrationPolicy not called.

    - by Jimmy Selgen Nielsen
    Hi. I'm trying to upgrade my current application to use an abstract parent entity, with specialized sub entities. I've created a custom NSEntityMigrationPolicy, and in the mapping model I've set the Custom Policy to the name of my class. I'm initializing my persistent store like this, which should be fairly standard : NSError *error=nil; persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel: [self managedObjectModel]]; NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption, nil]; if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl options:options error:&error]) { NSLog(@"Error adding persistent store : %@",[error description]); NSAssert(error==nil,[error localizedDescription]); } When i run the app i get the following error : Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'The operation couldn’t be completed. (Cocoa error 134140.)' [error userInfo] contains "reason=Can't find mapping model for migration" I've verified that version 1 of the data model will open, and if i set NSInferMappingModelAutomaticallyOption i get a migration, although my entities are not migrated correctly (as expected). I've verified that the mapping model (cdm) is in the application bundle, but somehow it refuses to find it. I've also set breakpoints and NSLog() statements in the custom migration policy, and none of it runs, with or without NSInferMappingModelAutomaticallyOption Any hints as to why it seems unable to find the mapping model ?

  • Populate tableView with more than one array

    - by Ewoods
    The short version: Is there a way to populate one specific row in a tableView with one value from one array, then populate another row in that same tableView with one value from a different array? For example, cell 1 would have the first value from Array A, cell 2 would have the first value from Array B, cell 3 would have the first value from Array C, etc. The long version: I hope this isn't too confusing. I've got an array of names, and then three more arrays with actions associated with those people. For example, the names array has Jim, Bob, and Sue, and then there's an array for eating, reading, and sleeping that records every time each person does one of these things (all of these arrays are populated from a MySQL database). The names array is used to populate a root tableView. Tapping on one of the names brings up a detail view controller that has another tableView that only has three rows. This part is all working fine. What I want to happen is when I tap on a name, it moves to the detail view and the three cells would then show the last event for that person for each of the three activities. Tapping on one of those three events then moves to a new view controller with a tableView that shows every event for that category. For example, if I tapped on Bob, the second page would show the last time Bob ate, read, and slept. Tapping on the first row would bring up a table that showed every time Bob has eaten. So far I've only been able to populate the second tableView with all of the rows from one of the arrays. I need it the other way around (one row from all of the arrays).

  • How to use NSArray of NSArray object in objective c?

    - by user1306926
    I declared a NSArray object in .h file as @property (nonatomic, assign) NSArray *scnArray; and in .h file under - (void)viewDidLoad I created three different NSArray objects as NSArray *obj1 = [[NSArray alloc] initWithObjects:@"1",@"0",@"0",nil]; NSArray *obj2 = [[NSArray alloc] initWithObjects:@"0",@"3",@"0",nil]; NSArray *obj3 = [[NSArray alloc] initWithObjects:@"0",@"0",@"5",nil]; scnArray = [[NSArray alloc] initWithArray:obj1]; [scnArray arrayByAddingObjectsFromArray:obj2]; [scnArray arrayByAddingObjectsFromArray:obj3]; and if I access this scnArray from any other function NSArray *caseArray = [scnArray objectAtIndex:index];//index will be 0, 1, 2... I am getting BAD_ACCESS_ERROR. What is the problem here and how can I correct to use it?

  • Saving NSString to file

    - by Michael Amici
    I am having trouble saving simple website data to file. I believe the sintax is correct, could someone help me? When I run it, it shows that it gets the data, but when i quit and open up the file that it is supposed to save to, nothing is in it. - (BOOL)textFieldShouldReturn:(UITextField *)nextField { [timer invalidate]; startButton.hidden = NO; startButton.enabled = YES; stopButton.enabled = NO; stopButton.hidden = YES; stopLabel.hidden = YES; label.hidden = NO; label.text = @"Press to Activate"; [nextField resignFirstResponder]; NSString *urlString = textField.text; NSData *dataNew = [NSData dataWithContentsOfURL:[NSURL URLWithString:urlString]]; NSUInteger len = [dataNew length]; NSString *stringCompare = [NSString stringWithFormat:@"%i", len]; NSLog(@"%@", stringCompare); NSString *filePath = [[NSBundle mainBundle] pathForResource:@"websiteone" ofType:@"txt"]; if (filePath) { [stringCompare writeToFile:filePath atomically:YES encoding:NSUTF8StringEncoding error:NULL]; NSString *myText = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:NULL]; NSLog(@"Saving... %@", myText); } else { NSLog(@"cant find the file"); } return YES; }

  • What is the proper location for a sqlite3 database file?

    - by Elliot Chen
    Hi, Everyone: I'm using a sqlite3 database to store app's data. Instead of building a database within program, I introduced an existing db file: 'abc.sqlite' into my project and put it under my 'Resources' folder. So, I think this db file should be inside of 'bundle', so at my init function, I used following statement to read it out: NSString *path = [[NSBundle mainBundle] pathForResource:@"abc" ofType:"sqlite"]; if(sqlite3_open([path UTF8String], &database) != SQLITE_OK) ... It's ok that this db can be opened and data can be retrieved from it. BUT, someone told me that it's better to copy this db file into user folder: such as 'Document'. So, my question is: is it ok to use this db from main bundle directly or copy it to user folder then use that copy. Which is better? Thank you very much!

  • sizeToFit label voids align right / set minimum width of label

    - by Deco
    Here is my code I am using to make a label (which contains content of an unknown length) the correct height for the content. (lines is equal to 0) myLabel.text =[NSString stringWithFormat:@"%@", myLabelContent]; myLabel.frame = CGRectMake(myLabel.frame.origin.x, myLabel.frame.origin.y, myLabel.frame.size.width, 800); [myLabel sizeToFit]; The only problem is, it is resizing the width as well as the height. I have two labels side by side, one aligned left, one aligned right. The left aligned one works fine. However, the right aligned one becomes intended (from the right). Because of its width resize, the content always starts at the origin.x position (in effect) because the label is made to be the shortest width required. I hope that makes sense. Is there a way to override or reset the width after auto resize had solved the height problem, or set a minimum width for the label? Many Thanks in advance, Deco

  • Detect certain characters in a text field

    What is the easiest way to detect a character in a text field? I want to be able to detect a certain character and replace that character with another specific character. So If I write in a text field... "zyxw" I want it to be replaced with "abcd". I'm a newbie and don't really know where to start with this or how to go about it. If anyone has any methods of doing this, I would really appreciate it.

  • Testing if a UI element is hidden in an OCUnit test

    - by Logan Serman
    I have a button that is hidden under certain circumstances that I wish to test. The button is hidden with [theButton setHidden: YES] in the viewDidLoad method if it is appropriate. For simplicity, lets say that the button is hidden when the buttonIsHidden property is set to true in the view controller. Right now I am trying the following: self.viewController = [[ViewController alloc] init]; self.viewController.buttonIsHidden = YES; [self.viewController loadView]; UIButton *theButton = [...] // function I wrote to retrieve the button based on it's touch up inside action if (theButton) { NSLog(@"%c", theButton.hidden); return (theButton.hidden == true) } return NO; It looks like the hidden property is not what it should be, the NSLog lines from the above code are blank. But, if I output another property like the height, it outputs the correct value so I know it is getting the right button. How do I access the hidden property of the button in this case?

  • What is the correct way to add a subview to a new window, making it aware of its available window si

    - by favo
    Hi, This is some kind of a basic question: I am adding a new Subview to a window using: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { viewController = [[myViewController alloc] initWithNibName:@"myNib" bundle:nil]; [window addSubview:viewController.view]; This displays the view at 100% on the window, having the Clock overlaying some pixels of that view on top. Rotating makes the view aware of the clock and resizes it to begin correctly below the clock without any overlay. What is the correct way to add a subview to a new window, making it aware of its available window size?

  • Creating a cocoa Application without nib files/fully pragmatic

    - by Moddy
    Yes, I know this goes against the whole MVC principle! However, I'm just trying to whip up a pretty trivial application - and I've pretty much implemented it pragmatically. However, I have a problem... I create an Empty Project, copy all the frameworks over and set the build settings - and I get errors about the executable.. or lack of executable. The build settings all appear fine, but it tells me there is no executable - it will build + run fine.. however it doesn't run. There is no error either - it just appears to run very fast and cleanly! Unless I try and run gdb which politely tells me I need to give it a file first.. Running… No executable file specified. Use the "file" or "exec-file" command. So I created a Cocoa Application, removed all the stuff I didn't need (i.e the MainMenu.xib file..) and now I can compile my code perfectly.. however it dies with complaining that its "Unable to load nib file: MainMenu, exiting" I have gone through the Project Symbols and see that the code actually relies upon the nib file heavily, even if you don't touch it code-wise. (MVC again I guess..) So my question is - is there a simple way to compile just what you code, no added nib files, just the code you write and the frameworks you add? I assume it would be a blank project but my experience tells me otherwise?!
