    UIView *move_view;

    UIButton *btn;



}


@end




#import "Myview.h"


@implementation Myview

 // The designated initializer.  Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad.
- (id)init {
    if (self = [super init]) {

        // Custom initialization
        [move_view setFrame:CGRectMake(41, 91, 64, 82)];
        [move_view setBackgroundColor:[UIColor redColor]];


        btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
        [btn setFrame:CGRectMake(113, 298, 72, 37)];

    }
    return self;

// Implement loadView to create a view hierarchy programmatically, without using a nib.
- (void)loadView {

    [super loadView];
    [self.view addSubview:move_view];
    [self.view addSubview:btn];
}

Thank you

I guess you have to alloc+initialize the view in the init method. Also, are you sure you have alloc+init correctly the UIViewController and attached to the AppDelegate window?
Some other remarks:

• Do not call MyView a UIViewController subclass, the code is less understandable
• If you are loading the Controller from a NIB/XIB you’d better ovverrid the method - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
