I want to design a level select scene in my game. What I want is a very abstract design which consists of a single UIPickerView that has the width of the screen and about 200 px in height.
The following is from LevelSelect.m , which is a subclass of SKScene
-(id)initWithSize:(CGSize)size{
if (self = [super initWithSize:size]) {
/* Setup your scene here */
self.backgroundColor = [SKColor whiteColor];
for (int i = 0; i < 10; i++) {
NSString* levelString = [NSString stringWithFormat:#"Level %i",i];
[levelData setObject:levelString atIndexedSubscript:i];
}
UIPickerView *levelPickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(self.scene.size.width/2, self.scene.size.height/2, self.scene.size.width, 200)];
levelPickerView.dataSource = self;
levelPickerView.delegate = self;
levelPickerView.showsSelectionIndicator = YES;
[self addChild:levelPickerView];
}
return self;
}
I implemented the UIPickerView data source and delegate methods. But when i load the scene i get the following error .

I'm trying to implement jwplayer in ios app but using a very simple startup it is continuously throwing signal abort error

I have an UIImageView subclassed as CLImageView that has been implemented with lazy load.
Just ago I have encountered this error message :
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Exercised class for selector implementation needs to be pushed'
*** First throw call stack:
at line : if(self=[super initWithCoder:aDecoder]) {
- (instancetype)initWithCoder:(NSCoder *)aDecoder{
if(self=[super initWithCoder:aDecoder]){
self.placeholderImage = nil;
self.delegate = nil;
self.cacheEnabled = NO;
self.prettyLoad = NO;
}return self;
}
I have never seen this error until 5 years of iOS programming, and I could not find any information on this kind of message here.
If anybody can drop me some ideas would be grateful.
If you need more information just leave a comment or reply.
Thank you so much.

How can I fix this error? I think this is a thread error.
Here is my code:
- (IBAction)TipsSlider:(id)sender {
UISlider *slider = sender;
float valorFloat = slider.value;
int valInt = (int)valorFloat;
_dataSlider.text = [[NSString alloc]initWithFormat:#"%d", valInt];
}
- (IBAction)calcular:(id)sender {
UISlider *slider = sender;
float valorFloat = slider.value;
int valInt = (int)valorFloat;
_dataSlider.text = [[NSString alloc]initWithFormat:#"%d", valInt];
float valorIn= [[entrada text] floatValue];
float resultado = (valorFloat / 100) * valorIn;
NSString *resultadoFinal = [[NSString alloc]initWithFormat:#"%4.2f",resultado];
_salidaResultado.text = resultadoFinal;
}
It looks like you have connected an IBAction from a UIButton when you intended to use a UISlider.
You then assign the sender of the action (which is a button) to a slider and try to access its "value", only that UIButton instances do not respond to a "value" message and that's why you get the crash.
So, make sure you are "ctrl+dragging" from a slider in IB.
In my game, when I load a new level, the previous level seems to be still remaining in the view.. Each level has its own class and they all draw something on the screen. So if I have 2 or more levels of images loaded, that makes my game too slow. What can I do to unload the previous level? Thanks in advance..
- (void) finishedLevel: (Level *) level
{
levelNumber++;
levelClass = NSClassFromString([NSString stringWithFormat:
#"Level_%d", levelNumber]);
if (!levelClass) levelClass = [Level class];
currentLevel = [[levelClass alloc] initWithView: self.mainView];
self.mainView.levelLabel.text = [NSString stringWithFormat:#"Level %d", levelNumber];
gameRunning = NO;
}
I tried using the following but didn't really work
levelClass = NSClassFromString([NSString stringWithFormat:#"Level_%d", levelNumber-1]);
[levelClass removeFromSuperview];
Error message
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[Level_1 removeFromSuperview]: unrecognized selector sent to class 0x107644'
I've created a custom class which is a subclass of CCLayer and trying to use it for CCScrollLayer
The way I do it is:
//Store the my layers to an NSMutableArray
for (AACustomClassLayer *cardLayer in levels) {
[layers addObject:cardLayer];
}
Under the hood of CCScrollLayer it crashes at:
- (void) updatePages
{
// Loop through the array and add the screens if needed.
int i = 0;
for (CCLayer *l in layers_)
{
l.anchorPoint = ccp(0,0);
l.contentSize = [CCDirector sharedDirector].winSize;
l.position = ccp( (i * (self.contentSize.width - self.pagesWidthOffset)), 0 );
if (!l.parent)
[self addChild:l];
i++;
}
}
The implementation for the AACustomClassLayer class (subclass of CCLayer) looks like:
-(id)initWithChapter:(AALevel *)level {
self = [super init];
if (self) {
self.isTouchEnabled = YES;
//Here I'm adding the CCSprite to my layer
}
return self;
}

You should add a conditional check in your for loop that determines if the object you are getting from enumeration is in fact a CCLayer. Your crash log states that the anchorPoint setter was not available on some object, presumably on an object in your layers_ array since that is the code you have posted that deals with anchorPoints.
Enumeration is convenient, but you are casing all objects to CCLayer when it is possible that one of them is not. I don't know where you are adding objects to layers_ but is it possible you are adding an object that is not actually a CCLayer ?
