  • iPhone SDK: selectRowAtIndexPath with delegate methods

    - by norskben
    Hi SO I am using selectRowAtIndexPath to select a tableview in the same ViewController class, but this does not run the delegate methods, eg: tableView:didSelectRowAtIndexPath I would like these delegate methods to also be called. Is there another API call I can be using? Thanks From the apple docs: selectRowAtIndexPath:animated:scrollPosition: Selects a row in the receiver identified by index path, optionally scrolling the row to a location in the receiver. - (void)selectRowAtIndexPath:(NSIndexPath *)indexPath animated:(BOOL)animated scrollPosition:(UITableViewScrollPosition)scrollPosition Calling this method does not cause the delegate to receive a tableView:willSelectRowAtIndexPath: or tableView:didSelectRowAtIndexPath: message, nor will it send UITableViewSelectionDidChangeNotification notifications to observers.

  • Tableview reload data problem iphone sdk

    - by neha
    Hi all, I have a class A which is a subclass of uitableviewcontroller and one more class B which actually displays my tableview with its content is a subclass of A. There's an xml parser which parses my xml and stores the content in an nsmutablearray of application delegate. Now, I fetch this delegate array into a local nsmutablearray in class B to minimise the communication between the two classes i.e. delegate and class B and display that. After certain condition is met in class A, I'm calling xml parser to refill the delegate array and I'm calling class B's tableview reload method. The problem is when I call the tableview's reload data, class B's delegate methods are called. But before that I need to grab this delegate array in local array in class B. How shall I do that? Can anybody please help? Thanx in advance.

  • How to use HTTP Live Streaming protocol in iPhone SDk 3.0

    - by Pugal Devan
    Hi Guys, i have developed on IPhone application and submitted to App store. But my application got rejected based on below criteria. Thank you for submitting your yyyyyyyy application. We have reviewed your application and have determined that it cannot be posted to the App Store at this time because it is not using the HTTP Live Streaming protocol to broadcast streaming video. HTTP Live Streaming is required when streaming video feeds over the cellular network, in order to have an optimal user experience and utilize cellular best practices. This protocol automatically determines bandwidth available to users and adjusts the bandwidth appropriately, even as bandwidth streams change. This allows you the flexibility to have as many streams as you like, as long as 64 kbps is set as the baseline feed. In my apps i have to stream prerecorded m4v and mp3 files from my server. I used MPMoviePlayerController to stream and play those videos / audio. How to implement the HTTP Live Streaming Protocol in my apps? Also can i get some sample code? Thanks in advance!

    Hello, I want to draw a route between 2 locations on the map.. something as a tour guide.When the tourist clicks another location i want to be able to draw the route as well as inform the distance from current location. I am aware of sites on the internet which tell how to draw polylines on map. But,one such example had a preloaded .csv file with various coordinates. Is there an alternate way to get the coordinates..as the location is selected dynamically.If no, how do i get the information for intermediate coordinates?

  • iPhone SDK : UIImageView - Collapsing animation

    - by chris.o.
    Hi All, I'm trying to animating across the screen a horizontal bar with a color gradient. For simplicity, I chose to make a png of the fully extended bar, assign it to a UIImageView, and (attempt to) animate resizing of it using a UIView animation. The problem is that in the "closed" state of the Image, the portion of the image showing is not the part that I want. The image is arranged so that from L to R, a white to red color gradient occurs. The right side (about 20 pixels) is solid red and is the part I want to show when the bar is "collapsed". I'm trying to extend the image out by about 100 pixels to its full width. I referenced the "Buy Now" button example for my code as it seemed relevant" http://stackoverflow.com/questions/1669804/uibutton-appstore-buy-button-animation My code: [UIView beginAnimations:@"barAnimation" context:nil]; [UIView setAnimationDuration:0.6]; CGRect barFrame = bookBar.bounds; if (fExtendBar) { barFrame.origin.x -= 100; barFrame.size.width += 100; } else { barFrame.origin.x += 100; barFrame.size.width -= 100; } bookBar.frame = barFrame; [UIView commitAnimations]; I feel like this should be possible, maybe by setting an "offsetOfImage" to display in the UIImageView, but I can't seem to make it work. Also, I've noticed that the behavior is kind of consistent with what happens in Interface Builder when you resize an image. Then again, I would think there would be a way to override this behavior programmatically. Any suggestions (including other approaches) are welcome. Thanks, chris.o.

  • iPhone SDK 3.0 and symbolicatecrash not getting along?

    - by Steve
    * UPDATE * I've reinstalled with Snow Leopard, clean install. Completely wiped my existing Leopard install. Same problem persists. I've tried numbers of versions of symbolicatecrash to resolve symbols in my crash reports. From the version provided by Apple, to Alan's Quatermain's version posted on GitHub and finally from http://openradar.appspot.com/6438643. For whatever reason, the best results I can get is for symbols on my own libraries to get resolved. Normally, this is enough data to point me in the right direction -- other times it is not. With 2.x I had no problems getting the symbols for my code + Apple provided libraries from within the stack traces in each thread. Most likely an issue with my environment here, I'm not at all doubting the work that Apple or Alan have done. Yes I'm certain the dSYM I have stashed away is the same exact one that's generating the crash report. Although 'Foo' is me, and getting symbols from it is wonderful, I need to see symbols from the other functions in the stack to truly understand my reports. Note: For devices that crash running the app on iPhone OS 2.2.1, I have no problem getting all symbols. This is an iPhone OS 3.0 issue it appears. Also, while running symbolicatecrash in verbose mode here's a few of the things that struck me as wrong: - NO MATCH NOT searching in Spotlight for dsym with UUID of /System/Library/Frameworks/CoreFoundation.framework/CoreFoundation ## Warning: Can't find any unstripped binary that matches version of /System/Library/Frameworks/CoreFoundation.framework/CoreFoundation ..........fetching symbol file for libobjc.A.dylib--[undef] Searching [/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0 (5A345)/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0 (5A347)/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0.1 (5B108)/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0.2 (5C1)/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.1.1/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.1/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.2.1/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.2/Symbols/usr/lib/libobjc.A.dylib /Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0 (7A341)/Symbols/usr/lib/libobjc.A.dylib]...--[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0 (5A345)/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0 (5A347)/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0.1 (5B108)/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.0.2 (5C1)/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.1.1/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.1/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.2.1/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/2.2/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH --[/Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0 (7A341)/Symbols/usr/lib/libobjc.A.dylib] -- NO MATCH NOT searching in Spotlight for dsym with UUID of /usr/lib/libobjc.A.dylib ## Warning: Can't find any unstripped binary that matches version of /usr/lib/libobjc.A.dylib Here's an example of the crash report after running it through symbolicatecrash: Thread 0 Crashed: 0 libSystem.B.dylib 0x31dc476c 0x31d46000 + 517996 1 libSystem.B.dylib 0x31dc4755 0x31d46000 + 517973 2 Foo 0x00053075 uncaught_exception_handler + 21 3 CoreFoundation 0x3028f65f 0x301fd000 + 599647 4 libobjc.A.dylib 0x30013693 0x3000c000 + 30355 5 libstdc++.6.dylib 0x374ccc2d 0x3748a000 + 273453 6 libstdc++.6.dylib 0x374ccc81 0x3748a000 + 273537 7 libstdc++.6.dylib 0x374ccd4d 0x3748a000 + 273741 8 libobjc.A.dylib 0x300135ff 0x3000c000 + 30207 9 CoreFoundation 0x30222f2d 0x301fd000 + 155437 10 CoreFoundation 0x30222ecb 0x301fd000 + 155339 11 Foundation 0x30521e33 0x30501000 + 134707 12 Foundation 0x30570d47 0x30501000 + 458055 13 Foo 0x0000a1db -[Bar barfoo] (Bar.m:1617) 14 Foo 0x00032f73 -[MyViewController foobar] (MyViewController.m:727) 15 Foo 0x000329b9 -[MyViewController foobar] (MyViewController.m:666) 16 Foo 0x00031fab -[MyViewController tabBar:tabSelected:] (MyViewController.m:440) 17 Foo 0x00068d41 -[TTTabBar setSelectedTabIndex:] (TTTabBar.m:160) 18 Foo 0x00068ca3 -[TTTabBar setSelectedTabView:] (TTTabBar.m:142) 19 Foo 0x000689cf -[TTTabBar tabTouchedUp:] (TTTabBar.m:83) 20 CoreFoundation 0x302552f9 0x301fd000 + 361209 21 UIKit 0x3094d101 0x308ed000 + 393473 22 UIKit 0x3094d0a1 0x308ed000 + 393377 23 UIKit 0x3094d073 0x308ed000 + 393331 24 UIKit 0x3094cdcd 0x308ed000 + 392653 25 UIKit 0x309779c1 0x308ed000 + 567745 26 UIKit 0x30977011 0x308ed000 + 565265 27 UIKit 0x309767d9 0x308ed000 + 563161 28 UIKit 0x30923613 0x308ed000 + 222739 29 UIKit 0x30923163 0x308ed000 + 221539 30 GraphicsServices 0x32045a4d 0x32041000 + 19021 31 CoreFoundation 0x30253041 0x301fd000 + 352321 32 CoreFoundation 0x30252771 0x301fd000 + 350065 33 GraphicsServices 0x32044b0f 0x32041000 + 15119 34 GraphicsServices 0x32044bbb 0x32041000 + 15291 35 UIKit 0x308f0363 0x308ed000 + 13155 36 UIKit 0x308ef121 0x308ed000 + 8481 37 Foo 0x00002097 main (main.m:13)

  • UITabBarController rotation problem with popViewControllerAnimated and selectedIndex (iPhone SDK)

    - by rjobidon
    Hi! This is a very important auto rotate issue and easy to reproduce. My application has a UITabBarController. Each tab is a UINavigationController. Auto rotation is handled with normal calls to shouldAutorotateToInterfaceOrientation and didRotateFromInterfaceOrientation. The interface rotates normally until I call UIViewController.popViewControllerAnimated and change UITabBarController.selectedIndex. Steps to reproduce: Create a demo Tab Bar Application. Add the following code to the App Delegate .h file: #import <UIKit/UIKit.h> @interface TestRotationAppDelegate : NSObject { UIWindow *window; UITabBarController *tabBarController; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet UITabBarController *tabBarController; -(void)doAction; @end // Redefine the interface to cach rotation messages @interface UITabBarController (TestRotation1AppDelegate) @end Add the following code to the App Delegate .m file: #import "TestRotationAppDelegate.h" @implementation TestRotationAppDelegate @synthesize window; @synthesize tabBarController; -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [window addSubview:tabBarController.view]; [window makeKeyAndVisible]; return YES; } -(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } -(void)dealloc { [tabBarController release]; [window release]; [super dealloc]; } @end @implementation UITabBarController (TestRotation1AppDelegate) -(void)viewDidLoad { [super viewDidLoad]; // Add a third tab and push a view UIViewController *view1 = [[UIViewController alloc] init]; view1.title = @"Third"; UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:view1]; NSMutableArray *array = [[NSMutableArray alloc] init]; [array addObjectsFromArray:self.viewControllers]; [array addObject:nav]; self.viewControllers = array; // Push view2 inside the third tab UIViewController *view2 = [[UIViewController alloc] init]; [nav pushViewController:view2 animated:YES]; // Create a button to pop view2 UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; button.frame = CGRectMake(50, 50, 220, 38); [button setTitle:@"Pop this view" forState:UIControlStateNormal]; [button addTarget:self action:@selector(doAction) forControlEvents:UIControlEventTouchUpInside]; [view2.view addSubview:button]; } -(void) doAction { // ROTATION PROBLEM BEGINS HERE // Remove one line of code and the problem doesn't occur. [self.selectedViewController popViewControllerAnimated:YES]; self.selectedIndex = 0; } -(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } @end The interface auto rotates normally until you tap the button on tab #3. Your help will be geatly appreciated!

  • iPhone SDK: Audio Queue control

    - by codemercenary
    Hi all, I am new to the audio queue services so I have taken an example from a book called iPhone Cool Projects where it describes how to stream audio. I want to extend this to being able to play a continuous playlist of links to mp3 files like an internet radio. The problem with the example code it that it does not detect when a stream ends and does not call AudioQueueStop at any point, so I added a counter to number of buffers added to the queue, and then decrement this counter each time audioQueueOutputCallback is called by the queue. This works fine except if when the buffer count goes to 0, and then I add a call AudioQueueFlush(audioQueue) and then AudioQueueStop(audioQueue, false) I get an error. If I only call AudioQueueReset, it continues to load the buffers again, but plays them out faster then it loads them... getting stuck in a loop and then crashing. 2010-04-14 13:56:29.745 AudioPlayer[2269:207] init player with URL 2010-04-14 13:56:29.941 AudioPlayer[2269:207] did recieve data 2010-04-14 13:56:29.942 AudioPlayer[2269:207] audio request didReceiveData 2010-04-14 13:56:29.944 AudioPlayer[2269:207] >>> start audio queue 2010-04-14 13:56:29.960 AudioPlayer[2269:207] packetCallback count 2 2010-04-14 13:56:29.961 AudioPlayer[2269:207] add buffer: 1 2010-04-14 13:56:29.962 AudioPlayer[2269:207] did recieve data 2010-04-14 13:56:29.963 AudioPlayer[2269:207] audio request didReceiveData 2010-04-14 13:56:29.963 AudioPlayer[2269:207] packetCallback count 1 2010-04-14 13:56:29.964 AudioPlayer[2269:207] add buffer: 2 2010-04-14 13:56:29.965 AudioPlayer[2269:207] packetCallback count 13 2010-04-14 13:56:29.967 AudioPlayer[2269:207] add buffer: 3 2010-04-14 13:56:29.968 AudioPlayer[2269:207] done with buffer: 3 2010-04-14 13:56:29.969 AudioPlayer[2269:207] done with buffer: 2 2010-04-14 13:56:29.974 AudioPlayer[2269:207] done with buffer: 1 So this loop continues some 20 - 30 times and then it crashes. The first time it plays an audio file it queues up the buffers and then plays sound, but doesn't callback to delete them until some 100 or more have been played. Can anyone explain this behavior? I read that there was a limit of 1 audio queue for MP3 playback for the iPhone. Is that still true? If not then I suppose I should use another audio queue for the next mp3 stream. I've had a look through the apple docs but it doesn't explain this in any particular detail. A better insight into this would be great. TIA.

  • dynamic naming of UIButtons within a loop - objective-c, iphone sdk

    - by von steiner
    Dear Members, Scholars. As it may seem obvious I am not armed with Objective C knowledge. Levering on other more simple computer languages I am trying to set a dynamic name for a list of buttons generated by a simple loop (as the following code suggest). Simply putting it, I would like to have several UIButtons generated dynamically (within a loop) naming them dynamically, as well as other related functions. button1,button2,button3 etc.. After googling and searching Stackoverlow, I haven't arrived to a clear simple answer, thus my question. - (void)viewDidLoad { // This is not Dynamic, Obviously UIButton *button0 = [UIButton buttonWithType:UIButtonTypeRoundedRect]; [button0 setTitle:@"Button0" forState:UIControlStateNormal]; button0.tag = 0; button0.frame = CGRectMake(0.0, 0.0, 100.0, 100.0); button0.center = CGPointMake(160.0,50.0); [self.view addSubview:button0]; // I can duplication the lines manually in terms of copy them over and over, changing the name and other related functions, but it seems wrong. (I actually know its bad Karma) // The question at hand: // I would like to generate that within a loop // (The following code is wrong) float startPointY = 150.0; // for (int buttonsLoop = 1;buttonsLoop < 11;buttonsLoop++){ NSString *tempButtonName = [NSString stringWithFormat:@"button%i",buttonsLoop]; UIButton tempButtonName = [UIButton buttonWithType:UIButtonTypeRoundedRect]; [tempButtonName setTitle:tempButtonName forState:UIControlStateNormal]; tempButtonName.tag = tempButtonName; tempButtonName.frame = CGRectMake(0.0, 0.0, 100.0, 100.0); tempButtonName.center = CGPointMake(160.0,50.0+startPointY); [self.view addSubview:tempButtonName]; startPointY += 100; } }

  • iPhone SDK - UITabBarConroller and custom design

    - by Cheryl
    Hi I am having a problem with my tab bars at the bottom of the screen. The designer has decided it should be one colour (not black) when inactive and another colour when active. I have worked out how to replace the main colour of the tabbar by subclassing UITabBarController and doing this:- - (void)viewDidLoad { [super viewDidLoad]; CGRect frame = CGRectMake(0.0, 0, self.view.bounds.size.width, self.view.bounds.size.height); UIView *v = [[UIView alloc] initWithFrame:frame]; //get percentage values from digitalcolour meter and enter as decimals v.backgroundColor = [UIColor colorWithRed:.0 green:.706 blue:.863 alpha:1]; [tabBar1 insertSubview:v atIndex:0]; [v release]; } I just can't see how to make the active tabbar be a separate colour when it is selected. I have tried subclassing UITabBarItem but there doesn't seem to be any property for me to set to change the background colour of the tab. They also want to have the icons on the tab bar not be blue and grey and I can't figure out how to do that. In the ViewController for one tab bar item I have put this into viewdidload:- myTabBarItem *tabItem = [[myTabBarItem alloc] initWithTitle:@"listOOO" image:[UIImage imageNamed:@"starcopy.png"] tag:1]; tabItem.customHighlightedImage=[UIImage imageNamed:@"starcopy.png"]; self.tabBarItem=tabItem; [tabItem release]; tabItem=nil; and in my subclass of UITabBarItem I have put this:- -(UIImage *) selectedImage{ return self.customHighlightedImage; } Only I don't see the icon at all. If I put this into the viewDidLoad of my subclass of UITabBarController:- for (UITabBarItem *item in tabBar1.items){ item.image = [UIImage imageNamed:@"starcopy.png"]; } Then all my tab bars have the icon but they are blue (and grey when inactive) how would I get them not to become blue but stay their original colour? If you have any light on this problem please help as I have been banking my head on the wall for 2 days now and it's getting me down. Thanks in advance Cheryl

  • NSNumberFormatter crashing iPhone SDK 4.0b2

    - by Ward
    Hey there, I've got an app that's been in the app store for a while and functions perfectly on OS 3.1 - 3.13. However, when tested on 4.0b2 I noticed that it crashes in the same place every time, but only on the device, never on the simulator. I'm using a 3GS to test. On loadView I initialize an NSNumberFormatter object which is declared and retained in the interface so I have access to it everywhere. In my method I call it several times to convert string values into nsnumbers to be stored in a mutable dictionary. Here's an example: [myDictionary setObject:[myStyleFormatter numberFromString:@"1"] forKey:@"hours"]; [myDictionary setObject:[myStyleFormatter numberFromString:@"30"] forKey:@"minutes"]; [myDictionary setObject:[myStyleFormatter numberFromString:@"10"] forKey:@"seconds"]; For some reason it crashes as soon as it tries to set hours. The error is "attempt to insert nil value (key: hours)" Have I been doing something wrong all along? Has the api changed for 4.0b2? Thanks, Howie

  • 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.

    I have a login view controller that has a button and a UI text view that becomes the first responder. When the button is clicked it loads the forgot view controller and a new UI textview becomes the first responder. When I dissmis the modal view controller the keyboard also gets dismissed and when I load the forgot view controller again the keyboard will not pop up as the first responder. (IBAction) backBeg: (id) sender{ [self dismissModalViewControllerAnimated:YES]; }

  • Drawing CGPathRef in ScrollView using Iphone sdk.

    - by Ann
    Hi all. I want to draw some curve in my scroll view using CGPathRef. I tried to draw this path but i see only the part of my CGPathRef which located at 320x480 pixels. Is it way to do that. Thank you in advance. Here is my code path = CGPathCreateMutable(); CGContextBeginPath(ctx); CGContextMoveToPoint(ctx, [[pathArray objectAtIndex:0]CGPointValue].x,[[pathArray objectAtIndex:0]CGPointValue].y ); for(int i = 1; i < [pathArray count]; ++i) { CGContextAddLineToPoint(ctx, [[pathArray objectAtIndex:i]CGPointValue].x, [[pathArray objectAtIndex:i]CGPointValue].y); } CGContextClosePath(ctx); CGContextSetRGBFillColor(ctx, 0.5, 0.3, 0.2, 0.5); CGContextFillPath(ctx); And when I scroll my view the line does not change its location. My goal is to move this line during scrolling.
