  • Creating Actions from UIActionSheets help

    - by user337174
    I am using two UIAction sheets within my current project. I can get one to work perfectly fine but when i insert a second action sheet it runs the same arguements as the first. How do i define the actionsheets seperatly? -(IBAction) phoneButtonClicked:(id)sender { // open a dialog with just an OK button UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:[NSString stringWithFormat:@"Phone: %@",phone],nil]; actionSheet.actionSheetStyle = UIActionSheetStyleDefault; [actionSheet showInView:self.view]; // show from our table view (pops up in the middle of the table) [actionSheet release]; } -(IBAction) mapButtonClicked:(id)sender { // open a dialog with just an OK button UIActionSheet *mapActionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:[NSString stringWithFormat:@"Map"],nil]; mapActionSheet.actionSheetStyle = UIActionSheetStyleDefault; [mapActionSheet showInView:self.view]; // show from our table view (pops up in the middle of the table) [mapActionSheet release]; } -(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { if(buttonIndex == 0){ NSString *callPhone = [NSString stringWithFormat:@"tel:%@",phone]; NSLog(@"Calling: %@", callPhone); [[UIApplication sharedApplication] openURL:[NSURL URLWithString:callPhone]]; } }

  • http authenitcation in xcode

    - by user313100
    I am trying to make twitter work in my app and everything works fine except the code does not seem to recognize an error from twitter. If the username/password are not valid, I get an error message through this function: - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { NSString* strData = [[[NSString alloc] initWithBytes:[data bytes] length:[data length] encoding:NSASCIIStringEncoding] autorelease]; NSLog(@"Received data: %@", strData ) ; return ; } It prints: Received data: Could not authenticate you. . However, the app continues to the post a tweet view I have and ignores the error. Obviously, I do not have something setup right to detect such an error from twitter so my question is how do I get xcode to recognize an error like this? This uses basic http auth btw and don't mention anything about OAuth...just trying to get this to work for now.

  • Setting Corner Radius on UIImageView not working

    - by MarkPowell
    I'm at a bit of a loss. I've used the layer property of UIView to round the corners of multiple elements in my app. However, this one UIImageView is simply not complying. Not sure what I am missing. The UIImageView (called previewImage) is contained in a Table View Cell. I've tried setting the cornerRadius property multiple location (in the cell itself and in the controller that creates the cell) to no avail. static NSString *CellIdentifier = @"MyTableViewCell"; MyTableViewCell *cell = (MyTableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:CellIdentifier owner:self options:nil]; cell = [topLevelObjects objectAtIndex:0]; cell.previewImage.layer.cornerRadius = 20; //Made it 20 to make sure it's obvious. } Is there something about the way cells are loaded that I'm missing?

  • Programatically created UITableViewCell subclass only working on highlight

    - by squarefrog
    I've created a subclass of UITableViewCell but I'm struggling to get it to work properly. If I use UITableViewStyleDefault then the class only works when highlighted. If I use UITableViewStyleValue1 then it mostly works but I'm unable to change label fonts much. I tried researching but it seems everyone is doing this via a .xib file, but not programatically. Implementation file #import "ASCustomCellWithCount.h" @implementation ASCustomCellWithCount @synthesize primaryLabel,secondaryLabel,contentCountImage,contentCount; - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier { self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]; if (self) { // Initialization code contentCountImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed: @"tableCount.png"] ]; primaryLabel = [[UILabel alloc] init]; primaryLabel.textAlignment = UITextAlignmentLeft; primaryLabel.textColor = [UIColor blackColor]; primaryLabel.font = [UIFont systemFontOfSize: 20]; primaryLabel.backgroundColor = [UIColor clearColor]; secondaryLabel = [[UILabel alloc] init]; secondaryLabel.textAlignment = UITextAlignmentLeft; secondaryLabel.textColor = [UIColor blackColor]; secondaryLabel.font = [UIFont systemFontOfSize: 8]; secondaryLabel.backgroundColor = [UIColor clearColor]; contentCount = [[UILabel alloc] init]; contentCount.textAlignment = UITextAlignmentCenter; contentCount.font = [UIFont boldSystemFontOfSize: 15]; contentCount.textColor = [UIColor whiteColor]; contentCount.shadowColor = [UIColor blackColor]; contentCount.shadowOffset = CGSizeMake(1, 1); contentCount.backgroundColor = [UIColor clearColor]; [self.contentView addSubview: contentCountImage]; [self.contentView addSubview: primaryLabel]; [self.contentView addSubview: secondaryLabel]; [self.contentView addSubview: contentCount]; } return self; } - (void)layoutSubviews { [super layoutSubviews]; CGRect contentRect = self.contentView.bounds; // CGFloat boundsX = contentRect.origin.x; primaryLabel.frame = CGRectMake(0 ,0, 200, 25); secondaryLabel.frame = CGRectMake(0, 30, 100, 15); contentCount.frame = CGRectMake(contentRect.size.width - 48, contentRect.size.height / 2 - 13, 36, 24); contentCountImage.frame = CGRectMake(contentRect.size.width - 48, contentRect.size.height / 2 - 12, 36, 24); } - (void)setSelected:(BOOL)selected animated:(BOOL)animated { [super setSelected:selected animated:animated]; // Configure the view for the selected state } - (void)dealloc { [primaryLabel release]; [secondaryLabel release]; [contentCountImage release]; [contentCount release]; } @end And then to create the cell I use - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; ASCustomCellWithCount *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[ASCustomCellWithCount alloc] initWithStyle: UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } cell.textLabel.text = [NSString stringWithFormat:@"%@", [tempArray objectAtIndex: indexPath.row]]; cell.contentCount.text = @"49"; return cell; }

  • Recording audio from many source/microphones

    - by user657429
    I'm curious if it's possible to record audio from many sources and if not, what's the limitation. Many current devices have two internal microphones (basically for noise reduction). On top of that it's possible to plug additional external one using audiojack. You can as well have another audio stream via bluetooth headset. You are allowed to specify AudioSource in android but is it possible to do recording from many sources at the same time? I'm also interested how the situation look like on the iOS devices.

  • Problem of Sprites and labels are displayed by white boxes.

    - by srikanth rongali
    I am writing a game in cocos2d. I am using a function restartDirector in AppDelegate class. -(void)restartDirector{ [[CCDirector sharedDirector] end]; [[CCDirector sharedDirector] release]; if( ! [CCDirector setDirectorType:CCDirectorTypeDisplayLink] ) [CCDirector setDirectorType:CCDirectorTypeDefault]; [[CCDirector sharedDirector] setPixelFormat:kPixelFormatRGBA8888]; [CCTexture2D setDefaultAlphaPixelFormat:kTexture2DPixelFormat_RGBA8888]; [[CCDirector sharedDirector] setAnimationInterval:1.0/60]; [[CCDirector sharedDirector] setDisplayFPS:YES]; [[CCDirector sharedDirector] setDeviceOrientation:CCDeviceOrientationLandscapeLeft]; [[CCDirector sharedDirector] attachInView:window]; } This function I called in one of the game Scene . -(void)PracticeMethod:(id)sender { [MY_DELEGATE restartDirector]; CCScene *endPageScene = [CCScene node]; CCLayer *endPageLayer = [DummyScene node]; [endPageScene addChild:endPageLayer]; [[CCDirector sharedDirector] runWithScene:endPageScene]; // [[CCDirector sharedDirector] replaceScene:endPageScene]; } When used the replaceScene, there is no problem in game but the memory of abject allocation is high(I checked in leaks tool). So I used runWithScene. But , while using these when the scene DummyScene is loaded the sprites, labels in it are displayed by white boxes. I cannot see the sprites and labels. If I am using replaceScene everything thing is working fine but the memory allocation is high. this is my problem. Thank you.

  • Animate cell within a table

    - by amok
    That's what I have: - A table with a few rows, one column only What I am trying to accomplish: Double tap on any row should produce an animation of the cell. The animation that I want is a flip vertically of the row. I am displaying some data in each row and what I want to do is displaying the source of the data "on the back" of the row, so to speak. Is it possible? If yes, how?

  • Cocos2d - smooth sprite movement in tile map RPG

    - by Lendo92
    I've been working on a 2-D Gameboy style RPG for a while now, and the game logic is mostly all done so I'm starting to try to make things look good. One thing I've noticed is that the walking movement / screen movement is a little bit choppy. Technically, it should work fine, but either it seems to be having some quirks, either due to taking up a lot of processing power or just timing inconsistencies between moving the screen and moving the sprite. To move the sprite, once I know where I want to move it, I call: tempPos.y += 3*theHKMap.tileSize.width/5; id actionMove = [CCMoveTo actionWithDuration:0.1 position:tempPos]; id actionMoveDone = [CCCallFuncN actionWithTarget:self selector:@selector(orientOneMove)]; [guy runAction:[CCSequence actions:actionMove, actionMoveDone, nil]]; [self setCenterOfScreen:position]; Then, in orientOneMove, I call: [self.guy setTexture:[[CCTextureCache sharedTextureCache] addImage:@"guysprite07.png"]]; //the walking picture-I change texture back at the end of the movement id actionMove = [CCMoveTo actionWithDuration:0.15 position:self.tempLocation2]; id actionMoveDone = [CCCallFuncN actionWithTarget:self selector:@selector(toggleTouchEnabled)]; [guy runAction:[CCSequence actions:actionMove, actionMoveDone, nil]]; The code for the concurrently running setCenterOfScreen:position method is: id actionMove = [CCMoveTo actionWithDuration:0.25 position:difference]; [self runAction: [CCSequence actions:actionMove, nil, nil]]; So the setCenterOfScreen moves the camera in one clean move while the guy moving is chopped into two actions to animate it (which I believe might be inefficient.) It's hard to tell what is making the movement not perfectly clean from looking at it, but essentially the guy isn't always perfectly in the center of the screen -- during movement, he's often times a pixel or two off for an instant. Any ideas/ solutions?

  • Loading UINavigationController subclass from a Nib

    - by Rits
    My situation is as follows: My class SettingsViewController is a subclass of UINavigationController. That class contains the logic of its rootViewController. For example, it acts as the delegate and data source for two table views in that root view controller. I have no problem setting this up programmatically. In the initializer of SettingsViewController, I can create an additional UIViewController to serve as the root view controller, position the table views in its view, and set their delegates and data sources to self. But I want to load that root view via a Nib. The problem is, I do not know how to connect that Nib with my SettingsViewController, how to set the delegates and data sources. The SettingsViewController is not accessible from within the Nib. 'File Owner' represents the root view controller, not the SettingsViewController. How do I access my UINavigationController subclass from within my root view controllers Nib? Thanks in advance.

  • UIView remove itself from UIScrollView

    - by alex25
    Hi! Following Scenario: I have a = UIViewController A that contains a UIScrollView I have a second UIViewController "B" (amongst other things it contains a button) and add it to the ScrollView of A myView *mView = [[myView alloc] init]; [myScrollView addSubview:mView.view]; Is there a way that once the button is pressed that it(view) removes itself from the scrollview? I thought in the direction of setting the delegate of mView to "A" ?! But not sure how that should work in detail.... Any suggestions? Thanks!

  • How can I detect if a string contains punctuation marks at the end?

    - by Sheehan Alam
    Lets assume I have the string: "Hello I like your shoes #today...!" I am tokenizing the string by spaces: return [string componentsSeparatedByString:@" "]; So my array contains: Hello I like your shoes #today...! I want to focus on "#today...!" any word that has a # in the prefix I am changing the font color. How can I make sure that only "#today" has its font color changed? I would basically like to figure out if a word has a punctuation mark at the end, and change the color for characters before the punctuation mark.

  • pull down notification panel in iOS help for iPad

    - by Priya Chhabra
    I have developed an iPad application. In which I am using left/right swipes from corner of screen. The problem is when device is in landscape mode, (though the application is always in portrait orientation) and user wants to swipe left, it opens the notification panel instead of going to swipeAction that I had defined. Note that it works fine when device is kept in portrait mode. Is there any way to make pull down notification panel application orientation specific ? Any kind of help will be appreciated.

  • NSArray containObjects method

    - by Anthony Chan
    Hi, I have a simple question regarding xcode coding but don't know why things are not performing as I think. I have an array of objects (custom objects). I just want to check if this one is within the array. I used the following code: NSArray *collection = [[NSArray alloc] initWithObjects:A, B, C, nil]; //custom "Item" objects Item *tempItem = [[Fruit alloc] initWithLength:1 width:2 height:3]; //3 instance variables in "Item" objects if([collection containsObject:tempItem]) { NSLog(@"collection contains this item"); } I suppose the above checking will give me a positive result but it's not. Further, I checked whether the objects created are the same. NSLog(@"L:%i W:%i H:%i", itemToCheck.length, itemToCheck.width, itemToCheck.height); for (int i = 0, i < [collection count], i++) { Item *itemInArray = [collection objectAtIndex:i]; NSLog(@"collection contains L:%i W:%i H:%i", itemInArray.length, itemInArray.width, itemInArrayheight); } In the console, this is what I got: L:1 W:2 H:3 collection contains L:0 W:0 H:0 collection contains L:1 W:2 H:3 collection contains L:6 W:8 H:2 Obviously the tempItem is inside the collection array but nothing shows up when I use containsObject: to check it. Could anyone give me some direction which part I am wrong? Thanks a lot!

  • IUNavigationController loading more viewControllers

    - by Goods
    Not a Noob as yesterday, but still green. I have a UITabbarcontoller and a IUNavigationController they seem to work fine. I have a UITableviewController to which I loads my NSMutable array. The user clicks a cell and didSelectRowAtIndexPath xib is loaded onto the stack. I have a 'Learn More' button on the current xib. I've tried a few approaches to load a newer xib when the 'Learn More' button is pressed but have failed. Im thinking it has to do with the Navigation Controller? Do I need to import the navigationcontroller to every ViewControllerSubclass I make? Thanks.

  • MPMoviePlayerContentPreloadDidFinishNotification seems more reliable than MPMoviePlayerLoadStateDidChangeNotification

    - by user567889
    I am streaming small movies (1-3MB) off my website into my app. I have a slicehost webserver, I think it's a "500MB slice". Not sure off the top of my head how this translates to bandwidth, but I can figure that out later. My experience with MPMoviePlayerLoadStateDidChangeNotification is not very good. I get much more reliable results with the old MPMoviePlayerContentPreloadDidFinishNotification If I get a MPMoviePlayerContentPreloadDidFinishNotification, the movie will play without stuttering, but if I use MPMoviePlayerLoadStateDidChangeNotification, the movie frequently stalls. I'm not sure which load state to check for: enum { MPMovieLoadStateUnknown = 0, MPMovieLoadStatePlayable = 1 << 0, MPMovieLoadStatePlaythroughOK = 1 << 1, MPMovieLoadStateStalled = 1 << 2, }; MPMovieLoadStatePlaythroughOK seems to be what I want (based on the description in the documentation): MPMovieLoadStatePlaythroughOK Enough data has been buffered for playback to continue uninterrupted. Available in iOS 3.2 and later. but that load state NEVER gets set to this in my app. Am I missing something? Is there a better way to do this?

  • callbacks via objective-c selectors

    - by codemonkey
    I have a "BSjax" class that I wrote that lets me make async calls to our server to get json result sets, etc using the ASIHTTPRequest class. I set it up so that the BSjax class parses my server's json response, then passes control back to the calling view controller via this call: [[self delegate] performSelectorOnMainThread:@selector(bsRequestFinished:) withObject:self waitUntilDone:YES]; ... where "bsRequestFinished" is the callback method in the calling view controller. This all worked fine and well until I realized that some pages are going to need to make different types of requests... i.e. I'll want to do different types of things in that callback function depending on which type of request was made. To me it seems like being able to pass different callback function names to my BSjax class would be the cleanest fix... but I'm having trouble (and am not even sure if it's possible) to pass in a variable that holds the callback function name and then replace the call above with something like this: [[self delegate] performSelectorOnMainThread:@selector(self.variableCallbackFunctionName) withObject:self waitUntilDone:YES]; ... where "self.variableCallbackFunctionName" is set by the calling view controller when it calls BSjax to make a new request. Is this even possible? If so, advisable? If not, alternatives? EDIT: Note that whatever fix I arrive at will need to take into account the reality that this class is making async requests... so I need to make sure that the callback function processing is correctly tied to the specific requests... as I can't rely on FIFO processing sequence.

  • Not receiving touchesEnded/Moved/Cancelled after adding subView

    - by Sam
    Title more or less says it all. In response to a touchesBegan event, my UIViewController recolours itself and adds some subviews. It never receives the touchesEnded. I guess because the added subviews are somehow intercepting the event. I tried calling resignFirstResponder on the subviews to no avail. The code works fine when I don't add the child views and the touch events are called as normal. Any ideas? Thanks
