  • To find busstop with timetable data and more near me(current postion)

    - by Sabby
    I am developing an application which helps the user to find the bus stops near him through his current latitude and longitude. This will also give the time table of the bus, route direction, bus name etc. I searched over the google but didn't get success. I tried the trimet api, but that was also not much helpful as it only works for Portland area and the pin is always dropped on the map on Portland. Please help me! Is there any api to do this? This app is for our client. User will input the route id, loc id or what and will get all the detail of near by bus stops and their lat,long.

  • Changing UITableViewCell height on a grouped cell doesn't look good

    - by Sheehan Alam
    I have a UITableView with 3 sections. In the first section I have 2 grouped cells. I am modifying the first cell to be larger than the second. Though the first cell resizes, it seems to mess up the cell below it. How can I resolve this? - (CGFloat)tableView:(UITableView *)tblView heightForRowAtIndexPath:(NSIndexPath *)indexPath { CGFloat rowHeight; if(indexPath.section == kBioSection) { switch(indexPath.row) { case kBioSectionDescriptionRow: rowHeight = 100; break; } } else { rowHeight = 50; } return rowHeight; }

  • Text being printed twice in uitableview

    - by user337174
    I have created a uitableview that calculates the distance of a location in the table. I used this code in cell for row at index path. NSString *lat1 = [object valueForKey:@"Lat"]; NSLog(@"Current Spot Latitude:%@",lat1); float lat2 = [lat1 floatValue]; NSLog(@"Current Spot Latitude Float:%g", lat2); NSString *long1 = [object valueForKey:@"Lon"]; NSLog(@"Current Spot Longitude:%@",long1); float long2 = [long1 floatValue]; NSLog(@"Current Spot Longitude Float:%g", long2); //Getting current location from NSDictionary CoreDataTestAppDelegate *appDelegate = (CoreDataTestAppDelegate *) [[UIApplication sharedApplication] delegate]; NSString *locLat = [NSString stringWithFormat:appDelegate.latitude]; float locLat2 = [locLat floatValue]; NSLog(@"Lat: %g",locLat2); NSString *locLong = [NSString stringWithFormat:appDelegate.longitude]; float locLong2 = [locLong floatValue]; NSLog(@"Long: %g",locLong2); //Location of selected spot CLLocation *loc1 = [[CLLocation alloc] initWithLatitude:lat2 longitude:long2]; //Current Location CLLocation *loc2 = [[CLLocation alloc] initWithLatitude:locLat2 longitude:locLong2]; double distance = [loc1 getDistanceFrom: loc2] / 1600; NSMutableString* converted = [NSMutableString stringWithFormat:@"%.1f", distance]; [converted appendString: @" m"]; It works fine apart from a problem i have just discovered where the distance text is duplicated over the top of the detailed text label when you scroll beyond the height of the page. here's a screen shot of what i mean. Any ideas why its doing this?

  • Should repeated use of the camera crash an app?

    - by Sam
    I have an app that builds a slideshow from user images. They can grab from their library or take a picture. I have found that repeated use of grabbing an image from the library is fine. But repeated use of taking a picture causes erratic behavior. I have been getting crashes but mostly what happens seems to be a reloading of the view after "didFinishPickingMediaWithInfo", which messes things up. I have no leaks and it seems to be releasing properly after each picture is taken. I am resizing the image and saving it in a data base. Is anyone else running into this situation? Was the camera not designed to be called this often?

  • Configure UIDatePicker with current locations time

    - by Telkitty
    I am using UIDatePicker in my current app, here is how I set a UILabel with the date time string obtained from the UIDatePicker. -(IBAction)AddTimeEnd:(id)sender { NSDate * date = [m_DateTimePicker date]; m_DateTimeLabel.text = [date description]; } Somehow the time I have entered (EST) kept on getting converted to US time in the UILabel. Does anyone know how to fix it? I would like the time entered in UIDatePicker to be consistent with the text in the label (probably the simplest way is set the locale for the UIDatePicker to be the local timezone)?

  • How to calculate end-point at a given center plus an radius and angle?

    - by mystify
    I'm trying to do some basic quartz core drawing with arcs, but have an F in math ;-) I have a point: CGPoint center = CGPointMake(100.0f, 100.0f); CGFloat radius = 50.0f; CGFloat startAngle = 20.0f / 180.0f * M_PI; CGFloat endAngle = 150.0f / 180.0f * M_PI; CGContextAddArc(c, center.x, center.y, radius, startAngle, endAngle, 0); Now I want to draw a little dot on the middle of the arc. I mean, not the center point, but the little curve (arc) which is made up between the angles 20-150 degrees. I looked into quartz but unfortunately, there seems no helper function to calculate this. Probably some hardcore trigonometric logic with atan and stuff of this kind needed?

  • Scroll immediately to row in table before view shows

    - by cannyboy
    A view with a table gets pushed onto the screen and I want it to scroll to a certain row in the table before the screen actually displays. I use this code within the final viewcontroller. NSIndexPath *scrollToPath = [NSIndexPath indexPathForRow:5 inSection:0]; [theTable scrollToRowAtIndexPath:scrollToPath atScrollPosition:UITableViewScrollPositionTop animated:NO]; When I put it in viewDiDAppear method, then it briefly flashes from the intial position of the table (at the top) to the row I want. I don't want it to show the initial position. If I put it in viewDidLoad or viewWillAppear then it crashes with a NSRangeException, presumably because the table isn't set up yet. How would I get it to scroll without showing the initial position?

  • How to know when the user touches the OK button of the last StoreKit alert "Thank you. Your purchase

    - by Walchy
    I have integrated "In App Purchase" in a game to let the user unlock more levels. Everything works fine, but I have a little problem with the last alert "Thank You. Your purchase was successful. [OK]". My program gets informed that the transaction was successfully completed before this last alert pops up and so my game starts running again - then the alert comes up, annoying the user. I would like to wait with my game running until the user touches the "OK" button, but since it is an alert from StoreKit I have no idea when this happens or how I could catch it. I don't want to create another dialog (this time my own, therefor under my control) below the alert, just asking for touching "OK" again - would be a bad user experience. Anybody have any ideas?

  • Portrait vs Landscape Launch Images

    - by andrewx
    An iPad app can support inclusion of launch images in both orientations; presumably, if your app supports auto-rotation, then this would suggest to me that if the user launches an app while the device is in Landscape mode, then the Landscape launch image is used. But in all the apps I've built and released, this has never been the case. Never once has the Landscape launch image appeared, only the Portrait. After loading, the app will auto-rotate to whatever orientation the device is in, but at launch, it assumes you are in Portrait. Always. Why? I have seen many other apps in the store that behave this way, but then there are some seem to always automatically know immediately at first launch, from that first launch image, that you are in Landscape, if that's the case. How is this done?

  • didFinishLaunchingWithOptions not called

    - by user1256477
    I'm having trouble enabling push notifications. with this code I try to enable the notification: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationType)(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)]; return YES; } It doesnt work, so I added a breakpoint in the line [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationType)(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)]; But it seems this part of the code is never execute. why is this not working?

  • formatting european characters from JSON results

    - by mlecho
    hi, i am building an application that imports JSON results and parses the objects to a table cell. Nothing fancy, but in my results, many of the terms/names are European with characters such as è or ú which come out as \u00E9 or \u00FA. I think these are ASCII ? or unicode? ( i can never keep em staight). Anyway, like all good NSSTring's, i figured there must be a method to fix this, but i am not finding it....any ideas? I am trying to avoid doing something like this: this posting. Thanks all.

  • How to calculate the y-pixels of someones weight on a graph? (math+programming question)

    - by RexOnRoids
    I'm not that smart like some of you geniuses. I need some help from a math whiz. My app draws a graph of the users weight over time. I need a surefire way to always get the right pixel position to draw the weight point at for a given weight. For example, say I want to plot the weight 80.0(kg) on the graph when the range of weights is 80.0 to 40.0kg. I want to be able to plug in the weight (given I know the highest and lowest weights in the range also) and get the pixel result 400(y) (for the top of the graph). The graph is 300 pixels high (starts at 100 and ends at 400). The highest weight 80kg would be plot at 400 while the lowest weight 40kg would be plot at 100. And the intermediate weights should be plotted appropriately. I tried this but it does not work: -(float)weightToPixel:(float)theWeight { float graphMaxY = 400; //The TOP of the graph float graphMinY = 100; //The BOTTOM of the graph float yOffset = 100; //Graph itself is offset 100 pixels in the Y direction float coordDiff = graphMaxY-graphMinY; //The size in pixels of the graph float weightDiff = self.highestWeight-self.lowestWeight; //The weight gap float pixelIncrement = coordDiff/weightDiff; float weightY = (theWeight*pixelIncrement)-(coordDiff-yOffset); //The return value return weightYpixel; }

  • Utility App with Navigation Controller and Table View on FlipSide.

    - by wdt
    Hi All. I am relatively new to the whole MVC way of looking at things. I have an application that is based on the "Utility" Application template. Everything in the MainView and FlipsideView is working great but now I need to add a TableView and Navigation Controller to the flipside. Without the navigation bar being on the MainView. So only once the user has tapped the info light button will the nav bar display on the flipside with a table view. I have been able to impliment the Table View on the side and populate it with data from an array. I am now struggling to link in a navigation controller so that the tableview can become interactive. When I place the nav bar code into the app delegate it appears on the MainView and not the flipside view. Where do I place the navigation bar code so that it will display on the flipsideview. I cannt seem to get the code in the right place. Also I am not sure I have the right code, do I put the UINavigationController code in the FlipSideViewController.m ? I am not grasping the concept of the naivgation controller fully I think . . . Here is the code to bring up the FlipView - (IBAction)showInfo { TableViewController *controller = [[TableViewController alloc] initWithNibName:@"TableViewController" bundle:nil]; controller.delegate = self; controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; [controller release]; } Now I need to get the TableViewController to have a navigation controller and a table view Thanks in advance.

  • Difference between two UIScrollView delegates

    - by Michael
    scrollViewDidEndScrollingAnimation and scrollViewDidEndDecelerating Looks like the last one is called when the bouncing effect is finished. But can't really understand what's the difference between first because they are called same time(well, decelerating called first).

  • Core Data-Linking one-to-many relationships

    - by Stelmate
    I have a one-to-many relationship where each department has many employees. When I create a new employee object I just link it to the parent department manually by setting the property to the instance of the department I have fetched from my fetch request. However, this seems to be improper because when I try to access the set of employees from the department by simply accessing the .employees property on my department object instance it returns a 0 count. Isn't the fault suppose to fire once I access a property? Am I linking my parent/child objects incorrectly?

  • Using CCSpriteFrameCache without CCSpriteBatchNode

    - by AwDogsGo2Heaven
    I want to know if there is any benefiting caching a sprite sheet and accessing the sprite by frame without using the CCSpriteBatchNode? In some parts of my game the sprite batch node is useful because there is a lot on the screen, however on another part its not, because there are just a few things, and there are requirements for layers so CCSpriteBatchNode wouldn't be useful. However, for the sake of consistency I would like to use Sprite Sheets for all my sprites, and so was beginning to wonder if I would still receive any benefit from it? (Or worse that it could some how be slower...)
