  • iPhone - Adding new sections and rows into UITableView

    - by Dev
    I have a UITableView to display a list of data. The list will contain images, so I am loading images with lazy loading. Now I don't want to load the whole list at a time. The loading should be like, first it should load some 10 records and when we scrolling down to the tableview, it should automatically load next 10 records as on. For this I need to add rows when I am scrolling to bottom. The tableview may contain different sections. So how can I add new rows and new sections at the end of the tableview while scrolling down?

  • MKPinAnnotationView - hard to drag

    - by James Zaghini
    I have a MKPinAnnotationView that the user can drag around the map. It is very difficult for a user to drag the pin. I've tried increasing the frame size and also using a giant custom image. But nothing seems to actually change the hit area for the drag to be larger than default. Consequently, I have to attempt to tap/drag about ten times before anything happens. MKPinAnnotationView *annView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"bluedot"] autorelease]; UIImage *image = [UIImage imageNamed:@"blue_dot.png"]; annView.image = image; annView.draggable = YES; annView.selected = YES; return annView; What am I missing here?

  • UITableView with multiple selections

    - by NewDev
    I have a UITableView with multiple selections enabled. If I select items and scroll the list back and forth they are remembered and shown and selected (blue background). Using the didDeselectRowAtIndexPath and didSelectRowAtIndexPath I am able to keep my own array of selected items. That part works well. However, if I then use the sectionForSectionIndexTitle and jump to a letter, the selection appears to be forgotten - even indexPathForSelectedRows appears to have been reset and is now empty. My own array remembers that an item is selected and I can set the cell.selected in the cellForRowAtIndexPath but the instant I move the list it is forgotten again. Any ideas? Is this a bug, or how do you retain the selection list when jumping to a letter?

  • swipe to delete uitableview cell; a bit jumpy?

    - by Veeru
    I have implemented "swipe to delete" on my table cell. It works fine, how ever, the delete button is a little jumpy; as in, i really have to position my finger on top of the button and carefully touch it to delete the record. I am not sure if am making it clear; let me do my best to explain When the delete button appears; the user has trouble clicking on it, it disappears the moment its clicked. THe user has to try a few times to actually delete the cell. Am not sure what the reason is, it just seems like the delete button gets hidden as though the user has clicked on a different part of the cell. Any suggestsions?

  • SLRequest return nil before block complete

    - by jaytr0n
    I'm having a little trouble thinking through this and deciding if it's a design flaw on my behalf or if I'm missing a piece that could make this work. Basically I'm using the new SLRequest to make a Twitter API call. After the data is returned, I'd like to put it into an object and return that object: -(AUDSlide *) getFollowerSlide { SLRequest *getRequest = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodGET URL:[NSURL URLWithString:[NSString stringWithFormat:@"https://api.twitter.com/1.1/followers/ids.json?user_id=%@", [[self.twitterAccount valueForKey:@"properties"] valueForKey:@"user_id"]]] parameters:nil]; getRequest.account = twitterAccount; AUDSlide *slide = [[AUDSlide alloc] init]; [getRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) { if ([urlResponse statusCode] == 200) { NSError *jsonError = nil; NSDictionary *list = [NSJSONSerialization JSONObjectWithData:responseData options:0 error:&jsonError]; NSLog(@"Number of Followers: %u", [[list objectForKey:@"ids"] count]); slide.title = @"Followers"; slide.number = [NSString stringWithFormat:@"%u",[[list objectForKey:@"ids"] count]]; } else{ slide.title = @"Error"; slide.number = [NSString stringWithFormat: @"E%u", [urlResponse statusCode]]; } }]; return slide; } Of course the slide is returned before the call is complete and returns a nil object. So I'm not sure if I should try to force this into a synchronous request (that seems like it could be a bad idea) or rethink the design. Does anyone have any advice?

  • 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???

  • Placing text on UIView in custom location

    - by JAM
    I am trying to calculate a position to place label on the screen. The goal is to place "word" label in lower right corner of the first square block If yellowish square is defined as myView = [[UIView alloc] initWithFrame:CGRectMake(100, 100, 70, 70)]; [self.view addSubview:myView]; [myView setBackgroundColor:[UIColor colorWithHexString:@"FFFFEC"]]; Using it, i'd like to place a label in it's lower right corner l1 = [[UILabel alloc] init]; [l1 setText:@"word"]; [l1 setFrame:CGRectMake(myView.frame.origin.x + myView.frame.size.width, myView.frame.origin.y + myView.frame.size.height, 700, 700)]; [l1 setFont:[UIFont fontWithName:@"Arial" size:10.0]]; [l1 setBackgroundColor:[UIColor colorWithHexString:@"CCFFFEC"]]; [l1 setTextAlignment:UITextAlignmentRight]; [l1 sizeToFit]; This is what happens: The matter here obviously, is in a correct offset. Knowing the font and size of text, how can one correctly calculate it?

  • How to set UITableViewCell highlighted image

    - by SmartTree
    I want to launch a method every time when user just highlights a cell (doesn't select it) in UITableView. Could you tell me please, how is it possible to do this ? I want to do it because I have a custom cell with a pictures on it and I want to change pictures every time when user highlights the cell. UPD: By highlight I mean that user just highlights a cell and don't release the finger from it. By select I mean when didSelectRowAtIndexPath is being launched (so the user releases the finger from the cell after he presses on it)

  • UIView rotate and than move

    - by user1790354
    I have problem with rotating and moving image (UIView). If I use this for rotate: [UIView beginAnimations: @"rotate" contex: nil]; [UIView setAnimationDuration: 1]; [UIView setAnimationBeginsFromCurrentState: YES]; [UIView setAnimationCurve: UIViewAnimationCurveLinear]; spaceShip.transform = CGAffineTransformMakeRotation (angle); // spaceShip is the UIView [UIView commitAnimations]; And this to move: [UIView beginAnimations: @"move" contex: nil]; [UIView setAnimationDuration: 1]; [UIView setAnimationBeginsFromCurrentState: YES]; [UIView setAnimationCurve: UIViewAnimationCurveLinear]; spaceShip.center = destanation // destanation is a point where user tap [UIView commitAnimations]; It's working well one at a time. But together this two animations don't work. Space Ship is rotating, but does not move in direction. Where my mistake? P.S. Early I have specify anchor point (0.5, 0.5). But when I rotate image it coordinates is changing.

  • Objective C convention: When to use For and when to use With

    - by Howard
    According to the Apple guideline , seems it is confusing, e.g. for method viewWithTag In Java, I would have a method called getViewByTag // Java version, equivalent to viewWithTag in Obj-C But I also found there are some method like objectForKey, so why not just use objectWithKey instead? getObjectByKey or just get // Java version, equivalent to objectForKey, // but why not objectWithKey? Or not viewForKey above?

  • Core Data to-many relationship in code

    - by Jan Bezemer
    I have three entities: Session, User and Test. A session has 0-many users and a user can perform 0-6 tests. (I say 0 but in the real application always at least 1 is required, at least 1 user for a session and at least 1 test for a user. But I say 0 to express an empty start.) All entities have their own specific data attributes too. A user has a name, A session has a name, a test has six values to be filled in by the user, and so on. But my issue is with the relationships. How do I set multiple users and have them added to one session (same goes for multiple tests for one user). How do I show the content in a right way? How do I show a session that has multiple users and these users having completed multiple tests? Here's my code so far with regard to issue 1: Session *session = [NSEntityDescription insertNewObjectForEntityForName:@"Session" inManagedObjectContext:context]; session.name = @"Session 1"; User *users = [NSEntityDescription insertNewObjectForEntityForName:@"User" inManagedObjectContext:context]; users.age = [NSNumber numberWithInt:28]; users.session = session; //sessie.users = users; [sessie addUserObject:users]; With regard to issue 2: I can log the session, but I can't get the user(s) logged from a session. NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Session" inManagedObjectContext:context]; [fetchRequest setEntity:entity]; NSArray *fetchedObjects = [context executeFetchRequest:fetchRequest error:&error]; for (Session *info in fetchedObjects) { NSLog(@"Name: %@", info.name); NSLog(@"Having problems with this: %@",info.user); //User *details = info.user; //NSLog(@"User: %@", details.age); }

  • Objective C - creating concrete class instances from base class depending upon type

    - by indiantroy
    Just to give a real world example, say the base class is Vehicle and concrete classes are TwoWheeler and FourWheeler. Now the type of the vehicle - TwoWheeler or FourWheeler, is decided by the base class Vehicle. When I create an instance of TwoWheeler/FourWheeler using alloc-init method, it calls the super implementation like below to set the value of common properties defined in the Vehicle class and out of these properties one of them is type that actually decides if the type is TwoWheeler or FourWheeler. if (self = [super initWithDictionary:dict]){ [self setOtherAttributes:dict]; return self; } Now when I get a collection of vehicles some of them could be TwoWheeler and others will be FourWheeler. Hence I cannot directly create an instance of TwoWheeler or FourWheeler like this Vehicle *v = [[TwoWheeler alloc] initWithDictionary:dict]; Is there any way I can create an instance of base class and once I know the type, create an instance of child class depending upon type and return it. With the current implementation, it would result in infinite loop because I call super implementation from concrete class. What would be the perfect design to handle this scenario when I don't know which concrete class should be instantiated beforehand?

  • UITextField in UITableViewCell Help

    - by W Dyson
    Hello All, I have scoured the internet looking for a good tutorial or posting about having a UITableView populated with a UITextField in each cell for data entry. I want to keep track of each UITextField and the text written within it while scrolling. The tableView will be sectioned. I have been using a custom UITableViewCell but I'm open to any method. Also, is it possible to use the textFields as ivars? If any of you could point me in the right direction, it would be greatly appreciated. Thank you in advance!

  • Timeout loading application on GAE using web2py

    - by Charles P.
    I am uploading an app to GAE. Through some experimentation I've found that if I don't include wsgihandler.py, the app loads very slowly. It feels like it's looking for this file and them timing out. Besides the slow loading, everything works perfectly without wsgihandler.py, so I want to know if there is a simple way to remove the references to the file. I tried poking around the files, but it doesn't look like there are direct references. Also, I asked before what I need at a minimum to get an application to work, and I found that I need: web2py/app.yaml web2py/gaehandler.py web2py/VERSION web2py/gluon/* (and subfolders, this is web2py) web2py/applications/theoneappyouwanttodeploy/* (and subfolders)

    I am adding a my header view to self.tableView.tableHeaderView=headerView; This tableView has 10 cells. I want to disable the cell Selection but, headerView touch events must be enabled. To achieve this I added the following code: self.tableView.userInteractionDisabled=YES; self.headerView.userInteractionDisabled=NO; self.headerView.exclusiveTouch=YES; Where I am wrong? Basic idea of implementation is , If headerView is enabled then cell selection is disabled and vice-versa.

  • Passing data from one viewcontroller to another

    - by user1392515
    I subclassed two view controllers. The first one is supposed to pass data, a NSUrl object to the second one. .m of the first one: NSURL *temp = [NSURL URLWithString:@"http://example.com"]; UIViewController *presentationsFullScreen_ViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"PresentationsFullScreen_ViewController"]; presentationsFullScreen_ViewController.urlToUse = temp; .h of the second one: #import <UIKit/UIKit.h> @interface PresentationsFullScreen_ViewController : UIViewController { NSURL *urlToUse; } @property (nonatomic,retain) NSURL *urlToUse; It is obviously not working and not compiling,telling me essentially that I didn't subclass it and that the property urlToUse is not found on UIViewController. How do I subclass correctly? Thanks!
