  • UITableViewCellStyleDefault image size

    - by Rob Bonner
    Hello all, I am getting some odd behavior from stock table cells, or maybe not odd, maybe I am making some assumptions. I create the cells as follows: cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; Then I assign an image to the default imageView property. My image usually comes in from a user, so it might be larger than the default size. To take care of this I: [cell.imageView setContentMode:UIViewContentModeScaleAspectFit]; which I expected to scale the image for me within the control, but in reality, the images are all over the map. So, is there a proper way to constrain the image in stock cell types? Thanks in advance!

  • Why I cannot get correct class of a custom class through isKindOfClass?

    - by Anthony Chan
    Hi, I've created a custom class AnimalView which is a subclass of UIView containing a UILabel and a UIImageView. @interface AnimalView : UIView { UILabel *nameLabel; UIImageView *picture; } Then I added in several AnimalView onto the ViewController.view. In the touchesBegan:withEvent: method, I wanted to detect if the touched object is an AnimalView or not. Here is the code for the viewController: @implementation AppViewController - (void)viewDidLoad { UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:... [self.view addSubview scrollview]; for (int i = 0; i<10; i++) { AnimalView *newAnimal = [[AnimalView alloc] init]; // customization of newAnimal [scrollview addSubview:newAnimal; } } - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; UIView *hitView = touch.view; if ([hitView isKindOfClass:[AnimalView class]]) { AnimalView *animal = (AnimalView *)hitView; [animal doSomething]; } } However, nothing happened when I clicked on the animal. When I checked the class of hitView by NSLog(@"%@", [hitView class]), it always shows UIView instead of AnimalView. Is it true that the AnimalView changed to a UIView when it is added onto the ViewController? Is there any way I can get back the original class of a custom class?

  • wait for CLLocationManager to finish before tweeting

    - by user295944
    I want to wait for latitude.text and longtitude.text to be filled in before sending a tweet, this code works fine, but I would rather not put the tweeting part in locationManager because I also want to sometimes update the current location without sending a tweet. How can I make sure the txt gets filled in before sending the tweet without doing this? - (IBAction)update { latitude.text =@""; longitude.text =@""; locmanager = [[CLLocationManager alloc] init]; [locmanager setDelegate:self]; [locmanager setDesiredAccuracy:kCLLocationAccuracyBest]; [locmanager startUpdatingLocation]; } - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { CLLocationCoordinate2D location = [newLocation coordinate]; latitude.text = [NSString stringWithFormat: @"%f", location.latitude]; longitude.text = [NSString stringWithFormat: @"%f", location.longitude]; TwitterRequest * t = [[TwitterRequest alloc] init]; t.username = @"****"; t.password = @"****"; [twitterMessageText resignFirstResponder]; loadingActionSheet = [[UIActionSheet alloc] initWithTitle:@"Posting To Twitter..." delegate:nil cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil]; [loadingActionSheet showInView:self.view]; [t statuses_update:twitterMessageText.text andLat:latitude.text andLong:longitude.text delegate:self requestSelector:@selector(status_updateCallback:)]; twitterMessageText.text=@""; }

  • remove an ASIHTTPRequest thread when it is done

    - by user262325
    Hello everyone I have a project in which it runs 5 download threads - (void)fetchThisURLFiveTimes:(NSURL *)url { [myProgressIndicator setProgress:0]; NSLog(@"Value: %f", [myProgressIndicator progress]); [myQueue cancelAllOperations]; [myQueue setDownloadProgressDelegate:myProgressIndicator]; [myQueue setDelegate:self]; [myQueue setRequestDidFinishSelector:@selector(queueComplete:)]; int i; for (i=0; i<5; i++) { ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url]; [request setDidFinishSelector:@selector(requestDone:)]; [request setDelegate:self]; [myQueue addOperation:request]; } [myQueue go]; } - (void)requestWentDone:(ASIHTTPRequest *)request { //.. } - (void)queueComplete:(ASINetworkQueue *)queue { NSLog(@"Value: %f", [myProgressIndicator progress]); } I hope to remove a thread when it is done. I do not know where I need to place my codes: requestWentDone:(ASIHTTPRequest *)request or queueComplete:(ASINetworkQueue *)queue I noticed there is no tag property for request, so I added it to ASIHTTPRequest to help me recognize which thread prompts the function reuqestWentDone, I can get the tag of different request, but I do not know how to remove the ASIHTTPRequest thread from myQueue. Welcome any comment Thanks interdev

  • Core Data Relationship List

    - by Dylan Copeland
    I'm not sure whether or not this is the appropriate way of doing this, but I was wondering what's the best way to approach a relationship to a value in a list with Core Data? For example, say you have a 'person' entity. Each person can have a different 'hair color'. I'm trying to basically define the hair colors in my data model and allow the 'person' entity to have a relationship to their given 'hair color. Is this possible? Good idea or bad? Thanks in advance.

  • Applying the same function to each object of an array in objective-c

    - by sagar
    Hey ! every one. I am having some query regarding Objective-c. Let's have a look to following code. NSArray *ar=[scrPDFPage subviews]; int i; for (i=0; i<[ar count]; i++) { [(UIView*)[ar objectAtIndex:i] removeFromSuperview]; } now my queries are as follows, Instead of rotating a loop, isn't there an option like, [ar applyFunctionToObjects:@selector(myFunction:)] Isn't there any option like [myView removeAllSubViews]; ( According to my knowledge, there is no option like remove all sub views, but in case you might know. ) Thanks in advance for sharing your knowledge. Sagar.

  • presentModalViewController does not want to work when called from a protocol method

    - by johnbdh
    I have a subview that when double tapped a protocol method on the subview's parent view controller is called like this... - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *theTouch = [touches anyObject]; if (theTouch.tapCount == 1) { } else if (theTouch.tapCount == 2) { if ([self.delegate respondsToSelector:@selector(editEvent:)]) { [self.delegate editEvent:dictionary]; } } } Here is the protocol method with the dictionary consuming code removed... - (void)editEvent:(NSDictionary){ EventEditViewController *eventEditViewController = [[EventEditViewController alloc] initWithNibName:@"EventEditViewController" bundle:nil]; eventEditViewController.delegate = self; navigationController = [[UINavigationController alloc] initWithRootViewController:eventEditViewController]; [self presentModalViewController:navigationController animated:YES]; [eventEditViewController release]; } The protocol method is called and runs without any errors but the modal view does not present itself. I temporarily copied the protocol method's code to an IBAction method for one of the parent's view button's to isolate it from the subview. When I tap this button the modal view works fine. Can anyone tell me what I am doing wrong? Why does it work when executed from a button on the parent view, and not from a protocol method called from a subview. Here is what I have tried so far to work around the problem... Restarted xCode and the simulator Ran on the device (iTouch) Presenting eventEditViewController instead of navigationController Using Push instead of presentModal. delaying the call to the protocol with performSelector directly to the protocol, to another method in the subview which calls the protocol method, from the protocol method to another method with the presentModal calls. Using a timer. I have it currently setup so that the protocol method calls a known working method that presents a different view. Before calling presentModalViewController it pops a UIAlertView which works every time, but the modal view refuses to display when called via the protocol method. I'm stumped. Perhaps it has something to do with the fact that I am calling the protocol method from a UIView class instead of a UIViewController class. Maybe I need to create a UIViewController for the subView?? Thanks, John

  • C-array to NSData and back

    - by Thor Frølich
    I'm attempting to save a c-style array of Vertex3D structs to an NSData object and get them back when reloading the app: NSData *vert = [NSData dataWithBytes:&vertices length:(sizeof(Vertex3D) * NUM_OF_VERTICES)]; This data is then saved and attempted to be read back into my c-array thusly: vertices = malloc(sizeof(Vertex3D) * NUM_OF_VERTICES); [vert getBytes:&vertices length:(sizeof(Vertex3D) * NUM_OF_VERTICES)]; The above results in “EXC_BAD_ACCESS” followed by: malloc: * error for object 0x48423c0: pointer being freed was not allocated I'm very new to programming so there's probably some fundamental memory management principle I'm unaware of. I have verified that the loaded NSData is identical to the saved one, but it's clear that the transition from c-array to NSData (and back) is not as I intended.

  • Custom UITableViewCell not properly hiding views

    - by adamweeks
    I am using apple's custom table view cell code and modifying the drawRect code within the cell's view to look like I want it to. I've changed it to have some UILabels as well as a UIProgressView. If the data the cell is being built on doesn't have a certain field, I want the UIProgressView to be hidden. This works for a little while, but when a cell gets requeued, the progress view will start displaying again, even when I set it to hidden = YES. I've tried just not creating the ProgressView unless the data was there and that didn't work either. I thought the answer was in the [self setNeedsDisplay] but that doesn't seem to help. Here is the code for the progressview from drawRect that continues to be displayed: UIProgressView *c1Progress = [[UIProgressView alloc]initWithFrame:CGRectMake(20.0, 70.0, 280.0, 12.0)]; float iProgress = (value / target); c1Progress.progress = iProgress; if (!dataExists) { c1Progress.hidden = YES; } [self addSubview:criteria1Progress]; [c1Progress release];

  • extract data from Plist to array and dictionary

    - by Boaz
    Hi I made a plist that looks like that: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList 1.0.dtd"> <plist version="1.0"> <array> <array> <dict> <key>Company</key> <string>xxx</string> <key>Title</key> <string>VP Marketing</string> <key>Name</key> <string>Alon ddfr</string> </dict> <dict> <key>Name</key> <string>Adam Ben Shushan</string> <key>Title</key> <string>CEO</string> <key>Company</key> <string>Shushan ltd.</string> </dict> </array> <array> <dict> <key>Company</key> <string>xxx</string> <key>Title</key> <string>CTO</string> <key>Name</key> <string>Boaz frf</string> </dict> </array> </array> </plist> Now I want to extract the data like that (all the 'A' for key "Name" to one section and all the 'B' "Name" to other one): NSString *plistpath = [[NSBundle mainBundle] pathForResource:@"PeopleData" ofType:@"plist"]; NSMutableArray *attendees = [[NSMutableArray alloc] initWithContentsOfFile:plistpath]; listOfPeople = [[NSMutableArray alloc] init];//Add items NSDictionary *indexADict = [NSDictionary dictionaryWithObject:[[attendees objectAtIndex:0] objectForKey:@"Name"] forKey:@"Profiles"]; NSDictionary *indexBDict = [NSDictionary dictionaryWithObject:[[attendees objectAtIndex:1] objectForKey:@"Name"] forKey:@"Profiles"]; [listOfPeople addObject:indexADict]; [listOfPeople addObject:indexBDict]; This in order to view them in sectioned tableView. I know that the problem is here: NSDictionary *indexADict = [NSDictionary dictionaryWithObject:[[attendees objectAtIndex:0] objectForKey:@"Name"] forKey:@"Profiles"]; But I just can't figure how to do it right. Thanks.

  • Activity Indicator not displaying based on whether the UIWebView is loading or not...
