    - by Iphony
    I want to get minimum and maximum date from date picker but minimum date should be "- 18" of current date and maximum date should be "- 100" of current date. Suppose current year is 2018 then I want minimum date 2000 and maximum date 1918. what I have done so far is : NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; NSDateComponents *components = [gregorian components:NSYearCalendarUnit fromDate:[NSDate date]]; NSInteger year = [components year]; int mindt = year - 18; int maxdt = year -100; // NSDate * MinDate = [components year] - 18; // NSDate * MaxDate = [components year] - 100; // self.datePicker.minimumDate = MinDate; // self.datePicker.maximumDate = MaxDate; but I cant get this integer to my date formate.. pls suggest any way ...

  • iPhone SDK - How to display a photo taken with the camera inside a UINavigationController?

    - by dan
    This is my code so far: /* class: myViewController @interface myViewController: UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate> */ - (IBAction) getPicture { UIImagePickerController * picker = [[UIImagePickerController alloc] init]; picker.delegate = self; picker.sourceType = UIImagePickerControllerSourceTypeCamera; [self presentModalViewController:picker animated:YES]; } - (void) imagePickerController:(UIImagePickerController *)thePicker didFinishPickingMediaWithInfo:(NSDictionary *)imageInfo { [[thePicker parentViewController] dismissModalViewControllerAnimated:YES]; UIImage *img = [imageInfo objectForKey:@"UIImagePickerControllerOriginalImage"]; self.myImageView.image = img; } So basically I'm trying to get a photo from the iPhone camera and display it in a UIImageView. This works perfectly fine as long the class myViewController is displayed as a standalone view. If I'm putting the View inside a UINavigationController the UIImageView won't display the image after taking one with the camera. But if I choose a picture from the library everything is fine again. So why does the UIImageView won't display a image taken with the camera inside a UINavigationController?

  • Problems with UITableView when loading the view into the main window

    - by GuidoMB
    I've created a sub class of UITableViewController named LoginViewController with the XIB file using XCode. Then I opened the XIB file with IB and set the table's style to grouped. Finally I wrote the following code: - (void)applicationDidFinishLaunching:(UIApplication *)application { LoginViewController *loginViewController = [[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:[NSBundle mainBundle]]; [window addSubview: loginViewController.view]; window.backgroundColor = [UIColor blueColor]; [window makeKeyAndVisible]; [window layoutSubviews]; } I set the window's background color to blue for you to see what the problem is. I put a link to the screenshot If I don't use the table style grouped the problem does not occur

  • NSSortdescriptor, finding the path to the key I wish to use for sorting.

    - by RickiG
    Hi I am using an NSSortdescriptor to sort a collection of NSArrays, I then came across a case where the particular NSArray to be sorted contains an NSDictionary who contains an NSDictionary. I would like to sort from the string paired with a key in the last dictionary. This is how I would reference the string: NSDictionary *productDict = [MyArray objectAtIndex:index]; NSString *dealerName = [[productDict objectForKey:@"dealer"] objectForKey:@"name"]; How would I use the dealerName in my NSSortdescriptor to sort the array? NSSortDescriptor * sortDesc = [[NSSortDescriptor alloc] initWithKey:/* ? */ ascending:YES]; sortedDealerArray = [value sortedArrayUsingDescriptors:sortDesc]; [sortDesc release]; Hope someone could help me a bit with how I go about sorting according to keys inside objects inside other objects:) Thank you.

  • Creating and releasing objects in the same method, while using self as delegate

    - by user200341
    In objective-c you are responsible for releasing objects you allocate, but what happens when you allocate an object in a method, assign self as the objects delegate, and then release the object. The callbacks from the newly created (and released) object fails at this point, or rather, doesn't happen. - (void)doSomething { MyObj *myObj = [[MyObj alloc] init]; myObj.delegate = self; [myObj performOperation]; [myObj release]; } - (void)callbackMethodFromMyObj:(NSString *)message { NSLog(message); } I can't release the object until the callback has occurred, and I can't avoid releasing the object in the same method that creates it (because it exists outside the scope). One way of doing it would be to pass the object along in the call-back and release it in the callback, but is this the right way to go about this?

  • iOS Development: Why isn't my try block catching the exception?

    - by BeachRunnerJoe
    Hi. I have an exception being thrown in my code, but when I wrap it in an try/catch block, it doesn't get caught. The NSLog statement is never called in the catch block. Here's the code... NSInteger quoteLength; [data getBytes:(void *)&quoteLength range:NSMakeRange(sizeof(messageType), sizeof(quoteLength))]; @try { //Debugger stack trace shows an NSException being thrown on this statement NSData *stringData = [data subdataWithRange:NSMakeRange(sizeof(messageType) + sizeof(quoteLength), [data length])]; NSString *quote = [[NSString alloc] initWithData:stringData encoding:NSUTF8StringEncoding]; NSLog(@"received quote: %@",quote); [quote release]; } @catch (NSException * e) { NSLog(@"Exception Raised: %@", [e reason]); } Why doesn't it get caught? Thanks so much!

  • How to create an image from canvas data?

    - by Jakub Hampl
    In my application I am trying to save an arbitrary part of a rendered HTML canvas to an image file. In my Javascript I call ctx.getImageData(x, y, w, h) and pass the resulting object to my macruby code (though if you know a solution in objc I am also very interested). There I'm trying to create a NSBitmapImageRep object so that I can then save to an image format the user desires. This is my code so far (the function gets a WebScriptObject as it's argument): def setimagedata(d) w = d.valueForKey("width").to_i h = d.valueForKey("height").to_i data = Pointer.new(:char, d.valueForKey("data").valueForKey("length").to_i) d.valueForKey("data").valueForKey("length").to_i.times do |i| data[i] = d.valueForKey("data").webScriptValueAtIndex(i).to_i end puts "data complete" # get's called @exported_image = NSBitmapImageRep.alloc.initWithBitmapDataPlanes(data, pixelsWide: w, pixelsHigh:h, bitsPerSample: 32, samplesPerPixel: 4, hasAlpha: true, isPlanar: false, colorSpaceName: NSCalibratedRGBColorSpace, bitmapFormat: NSAlphaNonpremultipliedBitmapFormat, bytesPerRow: 0, bitsPerPixel: 0) puts "done" # doesn't get called end The code doesn't seem to get through the initWithBitmapDataPlanes function but gives no error. My question is: what am I doing wrong? Is this approach reasonable (if not, what would be better?).

  • should variable be released or not? iphone-sdk

    - by psebos
    Hi, I have the following piece of code from a book. There is this function loadPrefs where the NSString *userTimeZone is being released before the end of the function. Why? The string was not created with alloc and I assume that the stringForKey function returns an autoreleased NSString. Is this an error or am I missing something? Is it an error in the book? (I new into objective-C) In the documentation for stringForKey the only thing it mentions is: Special Considerations The returned string is immutable, even if the value you originally set was a mutable string. The code: - (void) loadPrefs { timeZoneName = DefaultTimeZonePref; NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; NSString *userTimeZone = [defaults stringForKey: TimeZonePrefKey]; if (userTimeZone != NULL) timeZoneName = userTimeZone; [userTimeZone release]; show24Hour = [defaults boolForKey:TwentyFourHourPrefKey]; } Thanks!!!!

  • Navigationcontroller, why isnt this working?

    - by f0rz
    Hi ! Why wont this work? View1 loads View2. In view2: - (void) goToView { View3 *plainText = [[Tabview_testViewController alloc] initWithNibName:@"View3" bundle:nil]; [self.navigationController pushViewController:plainText animated: NO]; [plainText release]; } - (void)viewDidLoad { [self goToView]; [super viewDidLoad]; } This will not trigger navigationController to pushView, but if I add a button and setAction (goToView) it works perfectly. What kind of problem do I missing here? Regards

  • Adding a subview larger than cellHeight to a UITableViewCell?

    - by MathieuK
    I'm trying to add a subview to a UITableViewCell and the design that I'm working from demands that this particular subview (an image) needs to be larger than the actual UITableViewCell and thus partly overlap its siblings. So I've set up my table cell, generated my image and added it to the cell's contentView: // rowHeight for the UITableView is 45.0f UIImage *image = [self createCellThumbnail: someImage]; UIImageView *thumbView = [[UIImageView alloc] initWithFrame: CGRectMake(150, -5, 55,55)]; thumbView.transform = CGAffineTransformMakeRotation(0.1f); thumbView.image = image; cell.clipsToBounds = NO; cell.contentView.clipsToBounds = NO; [cell.contentView addSubview: thumbView]; While the image will 'overflow' into the cell below it, the top of the image is always clipped, as demonstrated here: http://imgur.com/WDsAx . Does anyone know if what I'm trying to do is possible with the current approach or should I just figure out a way to draw these images onto the UITableView after all the cells are drawn (it's a non-scrollable tableview, so that would work and be fairly easy).

  • How can I make text in a UILabel non-centered?

    I have a UILabel: descriptionLabel = [[UILabel alloc] initWithFrame:CGRectMake(200, 30, 130, 150)]; [descriptionLabel setFont:[Utils getSystemFontWithSize:14]]; [descriptionLabel setBackgroundColor:[UIColor clearColor]]; [descriptionLabel setTextColor:[UIColor whiteColor]]; descriptionLabel.numberOfLines = 0; descriptionLabel.lineBreakMode = UILineBreakModeWordWrap; [self addSubview:descriptionLabel]; If the text is only 1 line long it will appear in the middle of the label. Is there anyway I can have the text display from the top left corner of the label instead of the middle center?

  • detecting when nav controller popped to root

I need to detect hen the signupController has popped back to the root so I can take the data from the signup controller and do a registration or login. Any ideas? Thanks

  • Why self.view is not available

    - by amok
    I have this code in the main view controller and it is working just fine and as I wanted. loadingActionSheet = [[UIActionSheet alloc] initWithTitle:@"Posting To Twitter..." delegate:nil cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:nil]; [loadingActionSheet showInView:self.view]; I wanted that code to be reusable from different part of the project so I moved it in a separate file (UIView based). The poblem that I am facing is that self.view is not available there and I don't know why because I am learning and I don't know enough to understand what I am missing. What do I have to do/add/change to have the actionsheet shown in my current view even if that code lives somewhere else?

  • Simple iPhone tally method question

    - by Rob
    Just trying to create a simple method that counts up 1 on the tally when the button is pressed. My knowledge is extremely limited and I am pretty sure that my problem is somewhere in the method implementation: -(IBAction) updateTally:(id) sender { NSString *text; int total = 0; total = total + 1; text=[[NSString alloc] initWithFormat: @"%i", total]; lblTally.text = text; } I have done the necessary interface declarations for the lblTally UILabel and the updateTally method. I suspect that there is some sort of an NSString/int/%i/%@ mixup that I am making but I'm not sure how to fix it. When I run the program as it currently is it displays a 0 in the lblTally label field on the iphone. When I press the button it then displays a 1 in that field. However, if I continue to press the button - nothing happens.
