  • Simple addView problem

    - by Buyin Brian
    Hi there. I have a simple addView problem that is driving me nuts, I know I am overlooking something simple, perhaps another set of eyes can help. I have a Nib with a view that has a class identity set to TestView In my view controller, I use the following code: CGRect myRect = CGRectMake(0, 0, 320,240); TestView *myTest = [[TestView alloc] initWithFrame:myRect]; [self.view addSubview:myTest]; I have a NSLog in the TestView class's initWithFrame that fires when the above code is executed, but the view doesn't appear in the view controllers view. Thanks for your help.

  • Does a Category applied to NSString also apply to NSCFString via the "toll-free bridge"?

    - by half_brick
    We're integrating a library into an iPhone app which appears to use the google toolbox for iPhone internally. The google toolbox adds a method gtm_stringBySanitizingAndEscapingForXML to NSString. The problem is, whenever we attempt to make a call to this library we get [NSCFString gtm_stringBySanitizingAndEscapingForXML]: unrecognized selector sent to instance 0x272478 So it appears the library is calling that method on a NSCFString, to which the category does not apply. So... is it the case that the category will not apply across the toll-free bridge to CoreFoundation classes? If that's the case then we at least know why it's blowing up. Figuring out how to fix it is a different matter.

  • Accessing Instance Variables from NSTimer selector

    - by Timbo
    Firstly newbie question: What's the difference between a selector and a method? Secondly newbie question (who would have thought): I need to loop some code based on instance variables and pause between loops until some condition (of course based on instance variables) is met. I've looked at sleep, I've looked at NSThread. In both discussions working through those options many asked why don't I use NSTimer, so here I am. Ok so it's simple enough to get a method (selector? ) to fire on a schedule. Problem I have is that I don't know how to see instance variables I've set up outside the timer from within the code NSTimer fires. I need to see those variables from the NSTimer selector code as I 1) will be updating their values and 2) will set labels based on those values. Here's some code that shows the concept… eventually I'd invalidate the timers based on myVariable too, however I've excluded that for code clarity. MyClass *aMyClassInstance = [MyClass new]; [aMyClassInstance setMyVariable:0]; [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(doStuff) userInfo:nil repeats:YES]; [NSTimer scheduledTimerWithTimeInterval:5.0 target:self selector:@selector(doSomeOtherStuff) userInfo:nil repeats:YES]; - (void) doStuff { [aMyClassInstance setMyVariable:11]; // don't actually have access to set aMyClassInstance.myVariable [self updateSomeUILabel:[NSNumber numberWithInt:aMyClassInstance.myVariable]]; // don't actually have access to aMyClassInstance.myVariable } - (void) doSomeOtherStuff { [aMyClassInstance setMyVariable:22]; // don't actually have access to set aMyClassInstance.myVariable [self updateSomeUILabel:[NSNumber numberWithInt:aMyClassInstance.myVariable]]; // don't actually have access to aMyClassInstance.myVariable } - (void) updateSomeUILabel:(NSNumber *)arg{ int value = [arg intValue]; someUILabel.text = [NSString stringWithFormat:@"myVariable = %d", value]; // Updates the UI with new instance variable values }

  • Free UI tools for Cappuccino?

    - by avp
    Hi, I'm looking for free tools to design the UI for my web app. I'm pretty new to this field, so please point me to acceptable solutions. Basically, I need to fill a "screen" with some controls, that's it. Thanks. EDIT: Well, as soon as nobody answers, maybe somebody can help me with this problem for some framework other than Cappuccino?

  • How to hadle a tags inside another tags in NSXMLParser

    - by SimpleMan
    I have a file: <xml> <component>something <system>somethingDeeper <value>somethingDeepest</value> </system> </component> <component>somethinfDifferent <value>somethingDifferentDeeper</value> </component> <value>somethingNew</value> </xml> So i want to distinguish what is inside another tag (ex. <system>) what is not. How to do this with NSXMLParser ? I currently use BOOL ivar's but this is a lot of tags and this is not as elegant as i want it to be. I know that NSXMLParser is a SAX parser and i understand that. In above example I will be enter to didEndElement method three times with: elementName equal value Is there a more elegant way to distinguish what entry was from <component> tag above what not?

  • ViewController behaving oddly when pushed on the window

    - by ayazalavi
    I am using multiple controller during launch of an application in app delegate. One controller is for registration and the second controller is tabbar. tabbar was loading fine but when I pushed registration controller on window, contents went up by 20 units and I have good white blank screen at bottom. Therefore I recreated frame of my registration view controller in its viewdidload method and slided it 20 units down. The code is self.view.frame = CGRectMake(0, 20, self.view.frame.size.width, self.view.frame.size.height); and code in my app delegate for launch application was - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { if (![self accountExists]) { //code if account does not exists on iphone app database self.registerAccount = [[registerViewController alloc] initWithNibName:@"registerViewController" bundle:nil]; [window addSubview:registerAccount.view]; } else if([self autoLoginForAnyAccount]){ //code for autologin to app } else { self.tabBarController.selectedIndex = 1; self.tabBarController.delegate = self; [window addSubview:tabBarController.view]; } [window makeKeyAndVisible]; return YES; } if anyone knows why there is a white space at bottom when registration controller is pushed then please share it with me.

  • Problem with accessing classes from another class.

    - by srikanth rongali
    I have a classA, classB,classC. I have another class classABC; All are CCLayer inherited. I need to call all the classA, classB, classC from classABC. #import <Foundation/Foundation.h> #import "cocos2d.h" @interface classABC : CCLayer { classA *aClass; } @property(nonatomic, retain)classA *aClass; @end #import "classABC" #import "classA.h" #import "classB.h" #import "classC.h" @implementation classABC -(id)init { if( (self = [super init]) ) { ClassA *aClass = [[ClassA alloc]init]; CCScene *aClassS = [CCScene node]; CCLayer * aClassL = [aClass node]; [aClassS addChild: aClassL]; [[CCDirector sharedDirector] setAnimationInterval:60.0/60]; [[CCDirector sharedDirector] replaceScene: aClass]; } return self; } @end But I am not getting the classA displayed. How should I do it ? Thank You.

  • Error with custom Class definition in protocol

    - by Greg
    I'm trying to set up a custom delegate protocol and am getting a strange error that I don't understand. I wonder if someone could point out what I'm doing wrong here (I'm still new to Ob-C and protocol use)... The situation is that I've built my own URLLoader class to manage loading and parsing data from the internet. I'm now trying to set up a protocol for delegates to implement that will respond to the URLLoader's events. So, below is my protocol... #import <UIKit/UIKit.h> #import "URLLoader.h" /** * Protocol for delegates that will respond to a load. */ @protocol URLLoadResponder <NSObject> - (void)loadDidComplete:(URLLoader *)loader; - (void)loadDidFail:(URLLoader *)loader withError:(NSString *)error; @end However, I'm getting the following error for both method signatures: Expected ')' before 'URLLoader' I feel like I must be overlooking something small and silly. Any help folks could offer would be greatly appreciated! Whoops ... it was pointed out that I should include URLLoader.h. Here it is: #import <Foundation/Foundation.h> #import "URLLoadResponder.h" /** * URLLoader inferface. */ @interface URLLoader : NSObject { NSString *name; NSString *loadedData; NSMutableData *responseData; NSObject *delegate; BOOL _isLoaded; } @property (nonatomic, retain) NSString *name; @property (nonatomic, retain) NSString *loadedData; @property (nonatomic, retain) NSObject *delegate; - (void)loadFromURL:(NSString *)url; - (void)addCompleteListener:(id)observer selector:(SEL)sel; - (void)removeCompleteListener:(id)observer; - (void)parseLoadedData:(NSString *)data; - (void)complete; - (void)close; - (BOOL)isLoaded; + (NSURL *)makeUrlWithString:(NSString *)url; + (URLLoader *)initWithName:(NSString *)name; @end

  • Link a programmatic instantiation of class x in class y to a view controller of class x

    - by Joel Derfner
    I have classes Compose and Haiku, each connected to a view controller in IB. Haiku is instantiated in Compose as ghhaiku. Haiku has an array, self.arrayOfHaiku, with 117 members. But in Compose, self.ghhaiku.arrayOfHaiku has no members. I think the problem is that I haven't linked the instance of Haiku that has the 117-member array with the instance of Haiku created in Compose. But how do I do that? (I could of course be totally wrong and the problem could be something else, but that seems to make intuitive sense.) Any thoughts?

  • How can I access the int values of an object in an NSMutableArray?

    - by Daniel
    I try to access some values in a NSMutableArray I created, but I only get some numbers (address?) if I try to access them. I was able to initialize an array and can add and change objects with [myNSMutableArray addObject:[NSNumber numberWithInt:10]] and [myNSMutableArray replaceObjectAtIndex:0 withObject:[NSNumber numberWithInt:47] I also can print the value at index [0] with NSLog(@"%@", [myNSMutableArray objectAtIndex:0]); and I get 47 as expected. But how can I access the integer value of the object in the array so I can save it tomyIntValue?

  • UILabel with custom font displays *wrong* custom font

    - by winsmith
    I'm using this method to embed custom fonts in my iPhone app. The embedding works: When I run the following code, the fonts are listed. (Currently, I'm embedding all family members of Myriad Pro in OTF format) for( NSString *familyName in [UIFont familyNames] ){ for( NSString *fntName in [UIFont fontNamesForFamilyName:familyName] ){ NSLog(@"%@", fntName); }} When I try to set the font of a label to MyriadPro or MyriadPro-Bold, this works just as expected. However, when I set the font to MyriadPro-BoldCond, the label is still set in MyriadPro-Bold instead of the condensed version. (The font names are correct, I checked.) My Code: [recommendationLabel setFont:[UIFont fontWithName:@"MyriadPro-BoldCond" size:140]]; recommendationLabel.adjustsFontSizeToFitWidth = YES; What's the deal?

  • How to increment a value using a C-Preprocessor?

    - by mystify
    Example: I try to do this: static NSInteger stepNum = 1; #define METHODNAME(i) -(void)step##i #define STEP METHODNAME(stepNum++) @implementation Test STEP { // do stuff... [self nextFrame:@selector(step2) afterDelay:1]; } STEP { // do stuff... [self nextFrame:@selector(step3) afterDelay:1]; } STEP { // do stuff... [self nextFrame:@selector(step4) afterDelay:1]; } // ... When building, Xcode complains that it can't increment stepNum. This seems logical to me, because at this time the code is not "alive" and this pre-processing substitution stuff happens before actually compiling the source code. Is there another way I could have an variable be incremented on every usage of STEP macro, the easy way?

  • Vertical text in a Horizontal UIButton

    - by ArQangel
    I'm using a vertical UIButton in a portrait app (Just a normal button that is of width 60 and Height 160) I want to put the label Vetically down the button instead of across it. When I use the following code to rotate the label [workPackageButton.titleLabel setTransform:CGAffineTransformMakeRotation(M_PI / 2)]; It rotates the label but the length seems to be constrained by the original width, so I get the ... abreviation in the middle. Is there an easy way round this?

  • Yet Another Simple Retain Count Question

    - by yar
    [I'm sure this is not odd at all, but I need just a bit of help] I have two retain properties @property (nonatomic, retain) NSArray *listContent; @property (nonatomic, retain) NSArray *filteredListContent; and in the viewDidLoad method I set the second equal to the first self.filteredListContent = self.listContent; and then on every search I do this self.filteredListContent = [listContent filteredArrayUsingPredicate:predicate]; I thought I should do a release right above this assignment -- since the property should cause an extra retain, right? -- but that causes the program to explode the second time I run the search method. The retain counts (without the extra release) are 2 the first time I come into the search method, and 1 each subsequent time (which is what I expected). Some guidance would help, thanks! Is it correct to not release?
