Question

So hello i’m trying to load a different UIViews in UIViewController
with line like this
self.view=someView;

so here some code

- (void)viewDidLoad
{
    [self createMenuView];
}

- (void)createMenuView
{
    UIView *viewMenu=[[UIView alloc] initWithFrame:[UIScreen mainScreen].applicationFrame];
    viewMenu.backgroundColor=[UIColor grayColor];

    for(int i=0;i<3;i++){
        UIButton *Button=[UIButton buttonWithType:UIButtonTypeCustom];
        [Button setFrame:CGRectMake(0,0,320,80)];//creating it's frame
        [Button setCenter:CGPointMake(160,i*80+200)];//now place frame where we need
        [Button setTitle:[[NSString alloc] initWithFormat:@"%d",i] forState:UIControlStateNormal];//write k to title
        [Button setTag:[[[NSString alloc] initWithFormat:@"%d",i] intValue]];//write xy to tag
        [Button addTarget:self action:@selector(gameButtonClicked:) forControlEvents:UIControlEventTouchUpInside];//-event
        [Button setBackgroundImage:[UIImage imageNamed:@"blue.jpg"] forState:UIControlStateNormal];//set background
        [Button setAdjustsImageWhenHighlighted:FALSE];//disable tinting buttons while selected
        [viewMenu addSubview:Button];
    }
    self.view=viewMenu;
}

- (void)createGameView
{
    //here is just creation of a gameView which get's a whole lots of buttons
}

- (void)menuButtonClicked:(UIButton*)button
{
    [self createGameView];
}

if i do
[self createGameView]; in viewDidLoad then it’s okay
but if it’s from button then i get exception
help please

that’s what i get in output – not sure if it’s helpfull

UPD1:Tried to use [self setView:someView];instead of [self.view=someView]; – same exception

UPD2:
here is create gameView
ps:randExcludable – just arc4random()

- (void)createGameView
{
    UIView *viewGame=[[UIView alloc] initWithFrame:[UIScreen mainScreen].applicationFrame];
    viewGame.backgroundColor=[UIColor grayColor];

    int k=0;
    int n=4;
    int t=0,q=0;
    NSMutableArray *yEx=[[NSMutableArray alloc] initWithObjects:[[NSString alloc] initWithFormat:@"%d",5], nil],*xEx=[[NSMutableArray alloc] initWithObjects:[[NSString alloc] initWithFormat:@"%d",5], nil];

    for(int i=0;i<4;i++){
        t=[self randExclludable:n arrayToExclude:yEx];
        for(int j=0;j<4;j++){
            q=[self randExclludable:n arrayToExclude:xEx];
            UIButton *Button=[UIButton buttonWithType:UIButtonTypeCustom];//Creating button of custom type
            [Button setFrame:CGRectMake(0,0,80,80)];//creating it's frame
            [Button setCenter:CGPointMake(q*80+40,t*80+120)];//now place frame where we need
            [Button setTag:[[[NSString alloc] initWithFormat:@"%d",(t*10)+q] intValue]];//write xy to tag
            [Button setTitle:[[NSString alloc] initWithFormat:@"%d",k] forState:UIControlStateNormal];//write k to title
            [Button addTarget:self action:@selector(gameButtonClicked:) forControlEvents:UIControlEventTouchUpInside];//-event
            [Button setBackgroundImage:[UIImage imageNamed:@"blue.jpg"] forState:UIControlStateNormal];//set background
            if(i==0 && j==0){
                [Button setBackgroundImage:[UIImage imageNamed:@"gray.jpg"] forState:(UIControlStateNormal | UIControlStateDisabled)];//special background for the zero button
                [Button setEnabled:NO];//disable zero button
                [Button setTitle:@"" forState:UIControlStateNormal];//and set title of zero button to ""
            }
            [Button setAdjustsImageWhenHighlighted:FALSE];//disable tinting buttons while selected
            //[self.view addSubview:Button];//creating subview on the desired view
            //[self.buttons16 addObject:Button];//place button in array
            [viewGame addSubview:Button];
            Button=nil;
            k++;
            [xEx addObject:[[NSString alloc] initWithFormat:@"%d",q]];
        }
        [xEx removeAllObjects];
        [yEx addObject:[[NSString alloc] initWithFormat:@"%d",t]];
    }
    self.view=viewGame;
    //[self setView:viewGame];
    //[self.view addSubview:viewGame];
    viewGame=nil;
}

Answer 1

how stupid i was saw this just now while doing the same thing now with the UINavigationToolbar and swaping the whole UIViewController
the problem was that i gave menu buttons game buttons function which cause error because of changing the game view which is not created yet
