  • iPhone app running in Instruments fails with unrecognized selector

    - by Mark Smith
    I have an app that appears to run without problems in normal use. The Clang Static Analyzer reports no problems either. When I try to run it in Instruments, it fails with an unrecognized selector exception. The offending line is a simple property setter of the form: self.bar = baz; To figure out what's going on, I added an NSLog() call immediately above it: NSLog(@"class = %@ responds = %d", [self class], [self respondsToSelector:@selector(setBar:)]); self.bar = baz; On the emulator (without Instruments) and on a device, this shows exactly what I'd expect: class = Foo responds = 1 When running under Instruments, I get: class = Foo responds = 0 I'm stumped as to what could cause this. Perhaps a different memory location is getting tromped on when it's in the Instruments environment? Can anyone suggest how I might debug this?

  • iPhone - Merge keys in a NSArray (Objective-C)

    - by ncohen
    Hi everyone, I'm having troubles with arrays and keys... I have an array from my database: NSArray *elementArray = [[[menuArray valueForKey:@"meals"] valueForKey:@"recipe"] valueForKey:@"elements"] The problem here is that I would like all my elements of all my meals of all my menus in an array such that: [elementArray objectAtIndex:0] = my first element etc... In the example above, the elements are separated by the keys. How can I get that? Hope it's clear enough... Thanks

  • Adding UIViews with dynamic heights iphone

    - by Andy Jacobs
    in my viewcontroller's view i need to add a couple of custom UIView's, i do that in the loadView method so in my custom uiview's drawRect method i add a couple of UILabel's. in my viewcontroller's view i need to add all those custom UIView's underneath each other but i don't know what their height is sometimes 20px, 40px, 60px, depending on the outcome of the drawRect so when i init my custom UIView i give it a frame height of lets say 50.. but when the drawRect is done and it's only 20, 50 is too much so i need to adjust the frame height but how can i determine what's the visible height of the custom UIView and where can i catch it in my viewcontroller when the custom uiview has finished his drawRect method is there some kind of autoresize and where do i catch it in my viewcontroller, so i can position the custom uiview right under neath each other.

  • Locate RFID tag using iPhone

    - by Dan
    Hi all, I am looking into building an app (on my laptop to start) that would be able to locate the signal emitted by an RFID tag (non passive). Say I attach this to my key ring, what would be required of the application to triangulate the location of the RFID tag in a 10m range. Would this even be possible using this technology? I see some older posts here so wondering if there have been any tech breakthroughs in this area since then? Dan

  • Retain count problem iphone sdk

    - by neha
    Hi all, I'm facing a memory leak problem which is like this: I'm allocating an object of class A in class B. // RETAIN COUNT OF CLASS A OBJECT BECOMES 1 I'm placing the object in an nsmutablearray. // RETAIN COUNT OF CLASS A OBJECT BECOMES 2 In an another class C, I'm grabbing this nsmutablearray, fetching all the elements in that array in a local nsmutablearray, releasing this first array of class B. // RETAIN COUNT OF CLASS A OBJECTS IN LOCAL ARRAY BECOMES 1 Now in this class C, I'm creating an object of class A and fetching the elements in local nsmutable array. //RETAIN COUNT OF NEW CLASS A OBJECT IN LOCAL ARRAY BECOMES 2 [ALLOCATION + FETCHED OBJECT WITH RETAIN COUNT 1] My question is, I want to retain this array which I'm displaying in tableview, and want to release it after new elements are filled in the array. I'm doing this in class B. So before adding new elements, I'm removing all the elements and releasing this array in class B. And in class C I'm releasing object of class A in dealloc. But in Instruments-Leaks it's showing me leak for this class A object in class C. Can anybody please tell me wheather where I'm going wrong. Thanx in advance.

  • Simultaneous gesture recognizers in Iphone SDK

    - by minaevs
    I need to catch two different swipping gestures using UISwipeGestureRecognizer(for example, UISwipeGestureRecognizerDirectionRight and UISwipeGestureRecognizerDirectionLeft). When I add two different recognisers with addGestureRecognizer method, only last added recognizer works. I've read that I need to implement gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer: method of UIGestureRecognizerDelegate protocol, but nothing works. Can anyone help with simple example of catching two or more same gestures? Thanks!

  • iphone cannot rotate views in TabBar controller

    - by Luc
    Hello, I am working on an application that consists of a TabBar controller. Within on of its tab, I have a subclass of UITableViewController, within this list I have a Core-plot graph in the first cell and some other data in the 4 following cells. When I return YES in the shouldAutorotateToInterfaceOrientation method, I would expect the autoresizing of the list view to happen, but... nothing. When I add some log in the willRotateToInterfaceOrientation method, they are not displayed. Is there something I missed ? Thanks a lot, Luc // Override to allow orientations other than the default portrait orientation. - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations //return (interfaceOrientation == UIInterfaceOrientationPortrait); NSLog(@"Orientation"); return YES; } - (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration { [super willRotateToInterfaceOrientation:toInterfaceOrientation duration:duration]; NSLog(@"Rotating"); if (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight) { NSLog(@"view land:%@", self.view); } if (toInterfaceOrientation == UIInterfaceOrientationPortrait) { NSLog(@"view portrait:%@", self.view); } }

    Now that I installed SDK 3.2 for my iPad development, I need to build with the previous version for my old iTouch. Is this possible to switch or do I have to uninstall 3.2, install 3.1.x and re-install 3.2 in a "versioned" folder?

    Hi, In my application I m using following codes to crop the captured image :- -(void)imagePickerController:(UIImagePickerController *) picker didFinishPickingMediaWithInfo:(NSDictionary *)info { #ifdef _DEBUG NSLog(@"frmSkinImage-imagePickerController-Start"); #endif imageView.image = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; //======================================= UIImage *image =imageView.image; CGRect cropRect = CGRectMake(100, 100, 125,128); CGImageRef imageRef = CGImageCreateWithImageInRect([image CGImage], cropRect); [imageView setImage:[UIImage imageWithCGImage:imageRef]]; CGImageRelease(imageRef); //=================================================== //imgglobal = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; // for saving image to photo album //UIImageWriteToSavedPhotosAlbum(imageView.image, self, @selector(image:didFinishSavingWithError:contextInfo:), self); [picker dismissModalViewControllerAnimated:YES]; #ifdef _DEBUG NSLog(@"frmSkinImage-imagePickerController-End"); #endif } But my problem is that when I use camera to take photo to crop the captured image it rotates the image to 90 degree towards right and in case I use Photo library it works perfectly. So Can u filter my above codes to know where I m wrong. Please help me out its urgent Thanks In Advance

  • stack and heap issue for iPhone memory management

    - by Forrest
    From this post I got know that the Objective-C runtime does not allow objects to be instantiated on the stack, but only on the heap; this means that you don’t have “automatic objects”, nor things like auto_ptr objects to help you manage memory; Someone give one example in post Objective C: Memory Allocation on stack vs. heap NSString* str = @"hello"; but this NSString is also not allocated in stack. Feel odd that this str is static. (Who can explain this ? ) Question here is that why there is no heap ? even mixing c++ together with Object C ? /////////////////////////////// Clear my question /////////////////////////////// I am confused , so questions are not clear. Let me put in this way. 1) All Object C objects should be alloc in stack ? ( I think yes ) 2)In C++, there are stack for memory, so for iOS app, also have stack ? ( I think yes ) 3) for iOS app, if only use Object C, so what is the usage of stack ? what kind of objects should use stack then ?

  • iPhone smooth move and pinch of UIImageView

    - by Jacob
    I have an image view that I'm wanting to be able to move around, and pinch to stretch it. It's all working, but it's kinda jumpy when I start to do any pinch movements. The position will jump back and forth between the two fingers. - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { startLocation = [[touches anyObject] locationInView:mouth_handle]; if([touches count] == 2) { NSArray *twoTouches = [touches allObjects]; UITouch *first = [twoTouches objectAtIndex:0]; UITouch *second = [twoTouches objectAtIndex:1]; initialDistance = distanceBetweenPoints([first locationInView:mouth_handle],[second locationInView:mouth_handle]); } } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { CGPoint pt = [[touches anyObject] locationInView:mouth_handle]; CGRect frame = [mouth_handle frame]; frame.origin.x += pt.x - startLocation.x; frame.origin.y += pt.y - startLocation.y; frame.origin.x = (frame.origin.x < 58) ? 58 : frame.origin.x; frame.origin.x = (frame.origin.x > (260 - mouth_handle.frame.size.width)) ?

  • javascript scroll event for iPhone/iPad ?

    - by _ck_
    I can't seem to capture the scroll event on an iPad. None of these work, what I am doing wrong? window.onscroll=myFunction; document.onscroll=myFunction; window.attachEvent("scroll",myFunction,false); document.attachEvent("scroll",myFunction,false); They all work even on Safari 3 on Windows. Ironically, EVERY browser on the PC supports window.onload= if you don't mind clobbering existing events. But no go on iPad.

  • iPhone UIView frame animation inconsistent why?

    - by Rick
    I have an app that uses an image loaded in from an UIImagePickerController instance. Once the picker is dismissed so as to reduce the jarring transition from the picker layout to the layout of the next function I initially have the UIImageView for the image fill the whole screen and then when the picker is dismissed the image 'squeezes' up to the top left of the screen. from the initWithFrame... targetPicView = [[UIImageView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 480.0)]; [targetPicView setContentMode:UIViewContentModeScaleToFill]; this in a function called after dismissing the picker... [UIView beginAnimations:@"squeeze" context:context]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [UIView setAnimationDuration:0.75]; [targetPicView setFrame:CGRectMake(20.0, 20.0, 130.0, 150.0)]; [UIView commitAnimations]; The weird thing is that this works great when the image has been chosen from the library, the view shrinks down with the top left corner in place just as I planned but... If the image comes from the camera then the view shrinks with the top right corner in place instead and appears to come in from the left side of the screen. Can anyone shed any light on this?

  • Setting ivar in objective-c from child view in the iPhone

    - by Ivan
    Hi there! Maybe a FAQ at this website. I have a TableViewController that holds a form. In that form I have two fields (each in it's own cell): one to select who paid (single selection), and another to select people expense is paid for (multiple selection). Both fields open a new TableViewController included in an UINavigationController. Single select field (Paid By) holds an object Membership Multiple select field (Paid For) holds an object NSMutableArray Both vars are being sent to the new controller identically the same way: mySingleSelectController.crSelectedMember = self.crPaidByMember; myMultipleSelectController.crSelectedMembers = self.crSelectedMembers; From Paid for controller I use didSelectAtIndexPath method to set a mutable array of Memberships for whom is paid: if ([[tableView cellForRowAtIndexPath:indexPath] accessoryType] == UITableViewCellAccessoryCheckmark) { [self.crSelectedMembers removeObject:[self.crGroupMembers objectAtIndex:indexPath.row]]; //... } else { [self.crSelectedMembers addObject:[self.crGroupMembers objectAtIndex:indexPath.row]]; //... } So far everything goes well. An mutable array (crSelectedMembers) is perfectly set from child view. But... I have trouble setting Membership object. From Paid By controller I use didSelectAtIndexPath to set Membership: [self setCrSelectedMember:[crGroupMembers objectAtIndex:indexPath.row]]; By NSlogging crSelectedMember I get the right selected member in self, but in parent view, to which ivar is pointed, nothing is changed. Am I doing something wrong? Cause I CAN call the method of crSelectedMembers, but I can't change the value of crSelectedMember.

  • iPhone -- MKReverseGeocoder.adminstrativeArea -- getting state abbreviation

    - by rayjohannessen
    In the documentation for MKReverseGeocoder, the administrativeArea property gives you the current state the user is in, and it mentions in an example that it returns EITHER the state name OR its abbreviation. I am wondering if anyone knows how to get the abbreviation instead of the full state name...I have been able to find nothing that shows this is even a possibility besides that brief example that doesn't mention HOW. Thanks!

  • Preventing mouse emulation events (ie click) from touch events in Mobile Safari / iPhone using Javas

    - by Jaime Cham
    In doing a single page Javascript app with interactive DOM elements I've found that the "mouseover-mousemove-mousedown-mouseup-click" sequence happens all in a bunch after the "touchstart-touchmove-touchend" sequence of events. I've also found that it is possible to prevent the "mouse*-click" events from happening by doing an "event.preventDefault()" during the touchstart event, but only then, and not during the touchmove and touchend. This is a strange design, because because it is not possible to know during the touchstart yet whether the user intents to drag or swipe or just tap/click on the item. I ended up setting up a "ignore_next_click" flag somewhere tied to a timestamp, but this is obviously not very clean. Does anybody know of a better way of doing this, or are we missing something? Note that while a "click" can be recognized as a "touchstart-touchend" sequence (ie no "touchmove"), there are certain things, such as keyboard input focus, that can only happen during a proper click event.

  • TTNavigator doesn't use existing navigation bar (iPhone)

    - by user220770
    I am using the three20 framework in one view controller of my App. I create TTNavigator object and open a url which works fine. The problem is that TT creates it's own navigation bar and does not use the existing bar. There is no back button on the new nav bar so I cannot go back to my previous view controller. Has anybody run into this issue? Any ideas on how to fix (besides not using three20)? Thanks

  • Using iphone accelerometer AND UIEventSubtypeMotionShake event simultaneousluy.

    - by lukya
    Hi, I am using accelerometer to move/change things on the screen in my app. I also need to detect UIEventSubtypeMotionShake in the view controller for some other animations. As my app is a simple view based app, there is just one view controller which acts as UIAccelerometerDelegate AND FirstResponder (for detecting the shake event). After the first Shake gesture is detected, I don’t need accelerometer inputs through [accelerometer didAccelerate] method so I set the accelerometer delegate to nil. -(void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event { if (motion == UIEventSubtypeMotionShake) { NSLog(@"shake"); [[UIAccelerometer sharedAccelerometer] setDelegate:nil]; //my shake handling code } } The problem is that the first shake motion is not being detected correctly. I have to shake 2 3 or more times to trigger the UIEventSubtypeMotionShake event, while the subsequent shakes, after the accelerometer delegate is made nil, are being detected perfectly. This must be happening because UIEventSubtypeMotionShake in turn depends on the accelerometer didAccelerate events which are being overridden by my code. But I need to use both the events. Are there any apps or code samples which use both accelerometer and UIEventSubtypeMotionShake simultaneously? Thanks Swapnil

  • iPhone modalView unwanted offset

    - by Chonch
    Hey, I have a UITabBarController with three view controllers (from three different types). On one of the view controllers, I want to display a modalViewController. Once a UIButton on the screen is pressed, I perform this action: AboutViewController *modalViewController = [[AboutViewController alloc] initWithNibName:@"AboutScreen" bundle:nil]; [self presentModalViewController:modalViewController animated:YES]; like I always do in order to display a modal view... The problem is, that while the modal view is being displayed (while it is moving from the bottom of the screen), a 20 pixels grey strip is showing on the bottom of the screen (the same size as the status bar on the top). Once the modal view reaches its final location, the strip disappears. Needless to say this doesn't look good (to say the least). Does anybody know why this may happen? Thanks,
