Find where UIimageview frame is being set - objective-c

Question

I am working on an iPad application in Xcode 5 for a jigsaw puzzle game. I created the layout in storyboard, adding uiimageviews for each of 9 frames that would hold part of the image that was going to be the puzzle, and placed them on the view controller. Someone else has since removed the storyboard from the game and I need to go back and finish up the puzzle without it. The biggest issue I have is that the position of the frames seem to be being set somewhere outside of the view controller.h or .m classes and I can't find it. I am able to change the position of the pieces using image1.center in the touchesmoved method, but not in the viewdidload. I have been trying to track down where this is being set for several hours and am having no luck. Setting any movement of the center in viewdidload,viewwillappear, viewdidappear etc do not change the position as expected.
Can anyone either guide me on a way to change the image1.center after the view loads but without any user input, or else tell me how to trace all changes that are occurring in the view? I don't think seeing my code will help in this question since it is not seemingly changed in the classes that I am looking at, but I will post what works and what doesn't. I am only posting the portions that touch the uiimageview (1-9)
from .h
#implementation PuzzleViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
#interface PuzzleViewController : UIViewController
{
UIImageView *image1;
UIImageView *image2;
UIImageView *image3;
UIImageView *image4;
UIImageView *image5;
UIImageView *image6;
UIImageView *image7;
UIImageView *image8;
UIImageView *image9;
UIImage *puzzlePic;
}
from .m
- (void)viewDidLoad
{
[super viewDidLoad];
//set up buttons to accept user input
image1.userInteractionEnabled = true;
image2.userInteractionEnabled = true;
image3.userInteractionEnabled = true;
image4.userInteractionEnabled = true;
image5.userInteractionEnabled = true;
image6.userInteractionEnabled = true;
image7.userInteractionEnabled = true;
image8.userInteractionEnabled = true;
image9.userInteractionEnabled = true;
// Do any additional setup after loading the view from its nib.
puzzlePic = [LLFileManager getImage:#"star7.gif" folder:#"animation_images"];
[self placeImage];
}
// handle touches within images to move
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{
UITouch *touch = [[event allTouches] anyObject];
CGPoint touchLocation = [touch locationInView:self.view];
if([touch view] == image1){
image1.center = touchLocation;
}
else if([touch view] == image2){
image2.center = touchLocation;
}
else if([touch view] == image3){
image3.center = touchLocation;
}
else if([touch view] == image4){
image4.center = touchLocation;
}
else if([touch view] == image5){
image5.center = touchLocation;
}
else if([touch view] == image6){
image6.center = touchLocation;
}
else if([touch view] == image7){
image7.center = touchLocation;
}
else if([touch view] == image8){
image8.center = touchLocation;
}
else if([touch view] == image9){
image9.center = touchLocation;
}
}
// splits image into 9 equal parts, takes input of a ui image
-(NSArray *)splitImage9:(UIImage *)im{
NSMutableArray *images = [NSMutableArray array];
CGSize imageSize = im.size;
CGFloat xPos = 0.0, yPos = 0.0;
CGFloat width = imageSize.width/3;
CGFloat height = imageSize.height/3;
for (int y = 0; y < 3; y++) {
xPos = 0.0;
for (int x = 0; x < 3; x++) {
CGRect rect = CGRectMake(xPos, yPos, width, height);
CGImageRef cImage = CGImageCreateWithImageInRect([im CGImage], rect);
UIImage *dImage = [[UIImage alloc] initWithCGImage:cImage];
[images addObject:dImage];
xPos += width;
}
yPos += height;
}
return images;
}
// position pieces on board load
-(void)positionPieces{ // test, not working
CGPoint piece = CGPointMake(50,100);
image2.center = piece;
}
// places the cut images into view placeholders
-(void)placeImage{
NSArray *puzzleImage = [self splitImage9: puzzlePic];
[image1 setImage:[puzzleImage objectAtIndex:0]];
[image2 setImage:[puzzleImage objectAtIndex:1]];
[image3 setImage:[puzzleImage objectAtIndex:2]];
[image4 setImage:[puzzleImage objectAtIndex:3]];
[image5 setImage:[puzzleImage objectAtIndex:4]];
[image6 setImage:[puzzleImage objectAtIndex:5]];
[image7 setImage:[puzzleImage objectAtIndex:6]];
[image8 setImage:[puzzleImage objectAtIndex:7]];
[image9 setImage:[puzzleImage objectAtIndex:8]];
}

Answer 1

The biggest issue I have is that the position of the frames seem to be being set somewhere outside of the view controller.h or .m classes and I can't find it.
If the storyboard is gone, and if no code has been added to put the image views into the interface, then the interface should be empty. The reason you are seeing the interface at all must be because you are accidentally running an outdated version of the project.
To solve that problem, clean the project as I explain here:
How to Empty Caches and Clean All Targets Xcode 4
You will then find, when you run the project again, that the interface is now empty and the mystery is solved: the frames have no position, because there are no frames, because there are no image views at all.
