• How to find out if a method exists in Obj-C when given an NSString

  - by Justin

  I have a method as an NSString *. If it exists, I want to call it, and if not, do nothing. SEL eventSelector = NSSelectorFromString(eventSelectorStr); if ([delegate respondsToSelector:eventSelector]) { [delegate performSelector:eventSelector]; [delegate adapterDidFinishAdRequest:self]; } else { // Does not implement selector } This code does not work, since NSSelectorFromString will register the string as a selector, so respondsToSelector:eventSelector will cause a crash because the selector is actually invalid.

• Question About id and Delegate Usage in Obj-C

  - by Stunner

  Ey guys, I am wondering what the following line of code is doing: @property (assign, nonatomic) id <CoursePlannerDelegate> delegate; Namely I am wondering about this portion of the line: id <CoursePlannerDelegate> delegate; It also shows up in other places: @interface CategoryAddViewController : UIViewController { UITextField *nameField, *weightField; double maxWeight; //The maximum weight that can be allocated to this Category (max value of 100) id <CategoryAddDelegate> delegate; //A Course Planner TVC } Any help appreciated, thanks in advance!

• Concatenating Strings in Obj C

  - by eco_bach

  Hi It seems that Objective C jumps thru hoops to make seemingly simple tasks extremely difficult. I simply need to create a sequence of strings, image1.jpg, image2.jpg, etc etc ie in a loop var imgString:String='image'+i+'.jpg; I assume a best practice is to use a NSMutableString with appendString method? What am I doing wrong?? NSMutableString *imgString; for(int i=1;i<=NUMIMAGES;i++){ imgString.appendString(@"image"+i+@".jpg"); } I get the following error error: request for member 'appendString' in something not a structure or union

• XCode Obj-C: Make new NSArray from one key each out of an Array of Dictionaries

  - by user323772

  This actually could be a multipart question. But here's the first part ... I have an array (actually in a plist) of dictionaries. Each dictionary has 3 keys in it: (title), (points), and (description). I am trying to make a NEW array with the values of the key "title" from each dictionary in that first array. Let me explain WHY I am doing this and maybe that will provide a better all around explanation. I am trying to let people pick from a pre-determined list. Heck, if this was a web page it would be very simple since all I really care about are the "points" and the "Title". On a web site I could simply do a drop down combo-box with the "points" being the value and the title being the text for each row. But this is not a web page. So what I am trying to do here is pop out a modal picker when they click the text field. The modal picker shows the alphabetical ordered "titles" from our new array. And whichever one they select, it closes the modal view and assigns that "title" text to the UITextField which cannot be edited by the user. I have some code to get my modal picker to pop out. But I need to feed it an array of just the "titles" of each dictionary in my real array. Thanks in advance (and yes I am a newbie)

• Issue Displaying/Hiding Views (Obj-C iPhone Programming)

  - by roswell

  All right all, So I've got a UITableView that is inited in applicationDidFinishLaunching like so: [self showForumList]; Said method does this: -(void)showForumList { ForumList *fl = [ForumList alloc]; [fl initWithNibName:@"ForumList" bundle:[NSBundle mainBundle]]; self.ForumList = fl; [window addSubview:[self.ForumList view]]; [fl release]; }where self.ForumList is previously defined in the interface as ForumList *ForumList;, etc. Now, in ForumList (itself an extension of UITableViewController obviously), I've got didSelectRowAtIndexPath: -- within it I have the following code: Forum *f = [Forum alloc]; NSArray *forums = [f getForumList]; NSDictionary *selectedForum = [forums objectAtIndex:[indexPath row]]; NSString *Url = [selectedForum objectForKey:@"url"]; NSString *Username = [selectedForum objectForKey:@"username"]; NSString *Password = [selectedForum objectForKey:@"password"]; NSLog(@"Identified press on forum %@ (%@/%@)", Url, Username, Password); [self.globalDelegate showForumListFromForumUsingUrl:Url username:Username password:Password]; [self.globalDelegate closeForumList]; NSLog(@"ForumListFromForum init"); Both of the NSLog calls in this function are executed and perform as they should. Now, here is where the issue starts. self.globalDelegate is defined as AppDelegate *globalDelegate; in the Interface specification in my header file. However, [self.globalDelegate showForumListFromForumUsingUrl:username:password] and and [self.globalDelegate closeForumList] are never actually called. They look like so: -(void)closeForumList { NSLog(@"Hiding forum list"); [[self.ForumList view] removeFromSuperview]; } -(void)showForumListFromForumUsingUrl:(NSString *)Url username:(NSString *)Username password:(NSString *)Password { NSLog(@"Showing forum list from forum"); ForumListFromForum *fl = [ForumListFromForum alloc]; [fl initWithNibName:@"ForumListFromForum" bundle:[NSBundle mainBundle]]; [fl initFromForumWithUrl:Url username:Username password:Password]; self.ForumListFromForum = fl; [window addSubview:[self.ForumListFromForum view]]; [fl release]; } The app does not respond to my press and neither of these NSLog calls are made. Any idea where I've gone wrong?

• Obj C - how to customise the interval between slides with IKSlideShow

  - by doraemon

  I'm very new to Objective-C and Cocoa but I've made a simple app which uses ImageKit to present a slideshow using the IKSlideShow class. However I've got a bit stuck with something I thought would be simple. I want to increase the time photos are displayed on screen when the slideshow is playing, but I can't see how to do it effectively. The IKSlideshowDatasource protocol lets you do stuff when "slideshowDidChangeCurrentIndex" which seems to be the best place to do this - however I've tried putting various delays in here such as: while ( functionShouldPause ) { [[NSRunLoop currentRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:20]]; functionShouldPause=NO; } However they prevent the user for manually moving on the slides, or leaving the slideshow. Very grateful for any suggestions. Thanks!

• .NET: Calling GetInterface method of Assembly obj with a generic interface argument

  - by Khnle

  I have the following interface: public interface PluginInterface<T> where T : MyData { List<T> GetTableData(); } In a separate assembly, I have a class that implements this interface. In fact, all classes that implement this interface are in separate assemblies. The reason is to architect my app as a plugin host, where plugin can be done in the future as long as they implement the above interface and the assembly DLLs are copied to the appropriate folder. My app discovers the plugins by first loading the assembly and performs the following: List<PluginInterface<MyData>> Plugins = new List<PluginInterface<MyData>>(); string FileName = ...;//name of the DLL file that contains classes that implement the interface Assembly Asm = Assembly.LoadFile(Filename); foreach (Type AsmType in Asm.GetTypes()) { //Type type = AsmType.GetInterface("PluginInterface", true); // Type type = AsmType.GetInterface("PluginInterface<T>", true); if (type != null) { PluginInterface<MyData> Plugin = (PluginInterface<MyData>)Activator.CreateInstance(AsmType); Plugins.Add(Plugin); } } The trouble is because neither line where I am getting the type as by doing Type type = ... seems to work, as both seems to be null. I have the feeling that the generic somehow contributes to the trouble. Do you know why?

• Converting keys of an array/object-tree to lowercase

  - by tstenner

  Im currently optimizing a PHP application and found one function being called around 10-20k times, so I'd thought I'd start optimization there. function keysToLower($obj) { if(!is_object($obj) && !is_array($obj)) return $obj; foreach($obj as $key=>$element) { $element=keysToLower($element); if(is_object($obj)) { $obj->{strtolower($key)}=$element; if(!ctype_lower($key)) unset($obj->{$key}); } else if(is_array($obj) && ctype_upper($key)) { $obj[strtolower($key)]=$element; unset($obj[$key]); } } return $obj; } Most of the time is spent in recursive calls (which are quite slow in PHP), but I don't see any way to convert it to a loop. What would you do?

• Obj-C Sending Messages Between Classes

  - by user544359

  I'm a newbie in iPhone Programming. I'm trying to send a message from one view controller to another. The idea is that viewControllerA takes information from the user and sends it to viewControllerB. viewControllerB is then supposed to display the information in a label. viewControllerA.h #import <UIKit/UIKit.h> @interface viewControllerA : UIViewController { int num; } -(IBAction)do; @end viewControllerA.m #import "viewControllerA.h" #import "viewControllerB.h" @implementation viewControllerA - (IBAction)do { //initializing int for example num = 2; viewControllerB *viewB = [[viewControllerB alloc] init]; [viewB display:num]; [viewB release]; //viewA is presented as a ModalViewController, so it dismisses itself to return to the //original view, i know it is not efficient [self dismissModalViewControllerAnimated:YES]; } - (void)dealloc { [super dealloc]; } @end viewControllerB.h #import <UIKit/UIKit.h> @interface viewControllerB : UIViewController { IBOutlet UILabel *label; } - (IBAction)openA; - (void)display:(NSInteger)myNum; @end viewControllerB.m #import "viewControllerB.h" #import "viewControllerA.h" @implementation viewControllerB - (IBAction)openA { //presents viewControllerA when a button is pressed viewControllerA *viewA = [[viewControllerA alloc] init]; [self presentModalViewController:viewA animated:YES]; } - (void)display:(NSInteger)myNum { NSLog(@"YES"); [label setText:[NSString stringWithFormat:@"%d", myNum]]; } @end YES is logged successfully, but the label's text does not change. I have made sure that all of my connections in Interface Builder are correct, in fact there are other (IBAction) methods in my program that change the text of this very label, and all of those other methods work perfectly... Any ideas, guys? You don't need to give me a full solution, any bits of information will help. Thanks.

• OBJ-C - Getting a class name from a class hierarchy

  - by mmmilo

  Let's say I have the following headers: @interface SuperClass : NSObject @interface SubClass : SuperClass I'm alloc'ing an instance of the class by doing: SubClass *sc = [[SubClass alloc] init]; In my SuperClass.m: - (id) init { self = [super init]; if (self != nil) { NSString *cString = NSStringFromClass([self class]); } return self; } Simple, right? My question is: how can I get cString to return the SuperClass class, rather than the SubClass class? Since the SubClass is alloc'd/init'd, is this not possible? Thanks!

• Obj-C memory management for an NSView * instance variable

  - by massimoperi

  My custom view has a subview as an instance variable. Here is a sample interface: @interface MyCustomView : NSView { NSView *aSubview; } @end Then, in the .m file, I initialize aSubView and add it to the custom view. - (id)init { self = [super initWithFrame:CGRectMakeFrame(0.0, 0.0, 320.0, 480.0); if (self) { aSubview = [[NSView alloc] initWithFrame(0.0, 0.0, 100.0, 100.0); [self addSubview:aSubview]; } return self; } Where should I release aSubView? In the -dealloc method? - (void)dealloc { [aSubView release]; [super dealloc]; } Or directly after adding it to the custom view in the -init method? - (id)init { [...] [self addSubview:aSubview]; [aSubview release]; [...] } Which one is the best implementation?

• Why does obj.getBounds().height give a larger height than obj.height?

  - by TC

  I'm new to Flash and ActionScript, but managing quite nicely. One thing that is continuously getting in my way are the width and height properties of DisplayObject(Container)s. I'm finally starting to get my head around them and learned that the width and height of a Sprite are determined solely by their contents for example. I do not understand the following though: I've got a Sprite that I add a bunch of Buttons to. The buttons all have a height of 30 and an y of 0. As such, I'd expect the height of the containing Sprite to be 30. Surprisingly, the height is 100. The Adobe documentation of the height property of a DisplayObject states: Indicates the height of the display object, in pixels. The height is calculated based on the bounds of the content of the display object. Apparently, the 'bounds' of the object are important. So I went ahead and wrote this little test in the Sprite that contains the Buttons: for (var i:int = 0; i < numChildren; ++i) { trace("Y: " + getChildAt(i).y + " H: " + getChildAt(i).height); trace("BOUNDS H: " + getChildAt(i).getBounds(this).height); } trace("SCALEY: " + scaleY + " TOTAL HEIGHT: " + height); This code iterates through all the objects that are added to its display list and shows their y, height and getBounds().height values. Surprisingly, the output is: Y: 0 H: 30 BOUNDS H: 100 ... (5x) SCALEY: 1 TOTAL HEIGHT: 100 This shows that the bounds of the buttons are actually larger than their height (and the height that they appear to be, visually). I have no clue why this is the case however. So my questions are: Why are the bounds of my buttons larger than their height? How can I set the bounds of my buttons so that my Sprite isn't larger than I'd expect it to be based on the position and size of the objects it contains? By the way, the buttons are created as follows: var control:Button = new Button(); control.setSize(90, 30); addChild(control);

• How can I define a method with multiple optional arguments in Obj-C

  - by The Dark Bug Returns

  I want to be able to update two sets of identical buttons with one function. Also I don't want to update all the buttons, only some of them. Can I have a function like this?: -(void) updateFields{ updateButton1 : (Bool) x updateButton2 : (Bool) y updateButton3 : (Bool) z } The implementation will look like this: [button1_1 setEnabled:x]; [button1_2 setEnabled:x]; //called only if updateButton1 is given an argument [button2_1 setEnabled:y]; etc...

• Obj-c method override/polymorphism problem

  - by Rod

  Ok, so I'm using Objective-C. Now, say I have: TopClass : NSObject - (int) getVal {return 1;} MidClass : TopClass - (int) getVal {return 2;} BotClass : MidClass - (int) getVal {return 3;} I then put objects of each type into an NSMutableArray and take one out. What I want to do is run the getVal func on the appropriate object type, but when I put id a = [allObjects objectAtIndex:0]; if ([a isKindOfClass:[TopClass class]]) { int i; i = [a getVal]; } I get firstly a warning about multiple methods called getVal (presumably because the compiler can't determine the actual object type until runtime). But more seriously I also get an error "void value not ignored as it should be" and it won't compile. If I don't try and use the return from [a getVal] then it compiles fine e.g. [a getval]; //obviously no good if I want to use the return value It will also work if I use isMemberOfClass statements to cast the object to a class before running the function e.g. if ([a isMemberOfClass:[BotClass]) i = [(BotClass*) a getVal]; But surely I shouldn't have to do this to get the functionality I require? Otherwise I'll have to put in a statement for every single subclass, and worse have to add a new line if I add a new sub class, which rather defeats the point of method overriding doesn't it? Surely there is a better way?

• Using OpenGL Mathematics (GLM) in an Objective-C program

  - by user1621592

  i am trying to use GLM to load a .obj object in my Objective-C Program (Xcode 4.4 Mac Os X). I have added the glm folder to my project. i try to import it using #import "glm/glm.hpp", but the program doesn't build. some of the errors are the following: (this errors are produced in the GLM files) namespace glm{ //Unknown type name 'namespace' namespace detail { ..... it doesn't find the cstdlib, cmath, and other libraries.... This happens because my program is in Objective-c and the GLM doesn't work with this language??? How can i resolve this problem??? Thanks for your help.

• How do I generate mipmap .png and model .obj files for LibGDX?

  - by John Murdoch

  I'm playing a bit with LibGDX (OpenGL ES 2.0 wrapper for Android). I found some sample code which used prepared files to load models and mipmap textures for them, e.g., at https://github.com/libgdx/libgdx/blob/master/demos/invaders/gdx-invaders/src/com/badlogic/gdxinvaders/RendererGL20.java it reads .obj file for the model and RGB565 format .png file to apply a mipmapped texture to it. What is the best / easiest way for me to create these files? I understand .obj files are generated by a bunch of tools (I installed Blender, Wings3D and Kerkythea so far), but which ones will be the most user friendly for someone unfamiliar with 3D modelling? But more importantly, how do I produce a .png file with the mipmapped texture? The .png I looked at ( https://github.com/libgdx/libgdx/blob/master/demos/invaders/gdx-invaders/data/ship.png ) seems to include different textures for each of the faces, probably created with some tool. I browsed through the menus for the 3 tools I have installed but didn't find an option to export such a .png file. What am I missing?

• 3 index buffers

  - by bobobobo

  So, in both D3D and OpenGL there's ability to draw from an index buffer. The OBJ file format however does something weird. It specifies a bunch of vertices like: v -21.499660 6.424470 4.069845 v -25.117170 6.418100 4.068025 v -21.663851 8.282170 4.069585 v -21.651890 6.420180 4.068675 v -25.128481 8.281520 4.069585 Then it specifies a bunch of normals like.. vn 0.196004 0.558984 0.805680 vn -0.009523 0.210194 -0.977613 vn -0.147787 0.380832 -0.912757 vn 0.822108 0.567581 0.044617 vn 0.597037 0.057507 -0.800150 vn 0.809312 -0.045432 0.585619 Then it specifies a bunch of tex coords like vt 0.1225 0.5636 vt 0.6221 0.1111 vt 0.4865 0.8888 vt 0.2862 0.2586 vt 0.5865 0.2568 vt 0.1862 0.2166 THEN it specifies "faces" on the model like: f 1/2/5 2/3/7 8/2/6 f 5/9/7 6/3/8 5/2/1 So, in trying to render this with vertex buffers, In OpenGL I can use glVertexPointer, glNormalPointer and glTexCoordPointer to set pointers to each of the vertex, normal and texture coordinate arrays respectively.. but when it comes down to drawing with glDrawElements, I can only specify ONE set of indices, namely the indices it should use when visiting the vertices. Ok, then what? I still have 3 sets of indices to visit. In d3d its much the same - I can set up 3 streams: one for vertices, one for texcoords, and one for normals, but when it comes to using IDirect3DDevice9::DrawIndexedPrimitive, I can still only specify ONE index buffer, which will index into the vertices array. So, is it possible to draw from vertex buffers using different index arrays for each of the vertex, texcoord, and normal buffers (EITHER d3d or opengl!)

• Using OpenGL vertex buffers in C++.

  - by Ren

  I've loaded a Wavefront .obj file and drawn it in immediate mode, and it works fine. I'm now trying to draw the same model with a vertex buffer, but I have a question. My model data is organized in the following structures: struct Vert { double x; double y; double z; }; struct Norm { double x; double y; double z; }; struct Texcoord { double u; double v; double w; }; struct Face { unsigned int v[3]; unsigned int n[3]; unsigned int t[3]; }; struct Model { unsigned int vertNumber; unsigned int normNumber; unsigned int texcoordNumber; unsigned int faceNumber; Vert * vertArray; Norm * normArray; Texcoord * texcoordArray; Face * faceArray; }; As it is now, I don't think there is any redundant data, since multiple face structures can point to the same vertex, normal, or texture coordinate. When I make vbo's for the vertex positions, normals, and texture coordinates, and assign data to them with glBufferData, do I have to have make arrays with redundant data so that they will all have the same number of elements in the same order? I'd like to know if there is a simpler way to fill the buffers with the way I already have the model's data organized.

• Javascript cloned object looses its prototype functions

  I am attempting to clone an object in Javascript. I have made my own 'class' that has prototype functions. My Problem: When I clone an object, the clone cant access/call any prototype functions. I get an error when I go to access a prototype function of the clone: clone.render is not a function Can you tell me how I can clone an object and keep its prototype functions This simple JSFiddle demonstrates the error I get: http://jsfiddle.net/VHEFb/1/ function cloneObject(obj) { // Handle the 3 simple types, and null or undefined if (null == obj || "object" != typeof obj) return obj; // Handle Date if (obj instanceof Date) { var copy = new Date(); copy.setTime(obj.getTime()); return copy; } // Handle Array if (obj instanceof Array) { var copy = []; for (var i = 0, len = obj.length; i < len; ++i) { copy[i] = cloneObject(obj[i]); } return copy; } // Handle Object if (obj instanceof Object) { var copy = {}; for (var attr in obj) { if (obj.hasOwnProperty(attr)) copy[attr] = cloneObject(obj[attr]); } return copy; } throw new Error("Unable to copy obj!
