iOS - Landscape Only.
Hi,
I have a View Controller in a Storyboard that contains a hierarchy of Stack
Views, the leafs are a Custom Class that inherits from UIView. The Custom Class
LTWGameCellView : LTWDrawFrameView
LTWDrawFrameView is Custom Class has methods in it that draw a frame around the
View - this works fine.
LTWGameCellView inherits from LTWDrawFrameView and add up to 2 UIImageView
subviews to itself. The Images are resources in the project that are loaded at
runtime and added to the LTWGameCellView. The idea is to draw a Frame Around
but the Image, but also to inset the image a small amount.
I’m using auto layout and it works ok, except that I’m not sure I’m what I’m
doing is correct taking into account auto layout - please see code below. The
“setCellAsPlayedWithPieceImage:" is called when the a player plays a piece into
the Cell.
I want the (smaller) image to be centered in the (square) DrawFrame View.
Firstly I’m unsure if self.bounds is the correct starting place for placing the
image view and if I should be setting the frame anyway? Maybe I should be
adding a constraint to the Image View before I add it as a subview?
The problem I am seeing is that on the first run, the board is not setup
correctly in that the frames are different, if I re-restart a new game after
the first time, all is well. This is *was* being called from the
“viewWillAppear:" of the owing view controller (see code below), so I changed
things so that “newGame” is called from “viewDidAppear:”, this works well BUT
you see an annoying flicker when the View Controller first opens.
Any advice or help on this would be greatly appreciated.
All the Best
Dave
-(void) viewWillAppear:(BOOL) theAnimateFlag
{
[super viewWillAppear:theAnimateFlag];
[self newChaosCellViewDictionary];
//[self newGame];
}
-(void) viewDidAppear:(BOOL) theAnimateFlag
{
[super viewDidAppear:theAnimateFlag];
[self newGame];
}
These are the methods I am using to create the ImageViews and add them as a
subview.
The "setImageForCellWithImageFilePath:” setup up an Image View and stores it as
a property. Then, later on “setCellAsNormal” is called to Add the subview,
then later still, “setCellAsNormal'
-(void) setImageForCellWithImageFilePath:(NSString*) theImageFilePath
{
UIImage* myImage;
UIImageView* myImageView;
CGRect myImageFrameRect;
NSInteger myLineWidth;
//**
//** Setup the Line Width (also the Inset size of the Image
//**
myLineWidth = kLTWChaosCellViewFrameLineSize;
//**
//** Inset the Image Rectangle
//**
myImageFrameRect = self.bounds;
myImageFrameRect = CGRectInset(myImageFrameRect,myLineWidth,myLineWidth);
myImage = [[UIImage alloc] initWithContentsOfFile:theImageFilePath];
if (myImage == nil)
{
LTWAssertAlways(@"Cell Image Could Not be Found");
return;
}
//**
//** Create the Image View
//**
myImageView = [[UIImageView alloc] initWithImage:myImage];
[myImageView setFrame:myImageFrameRect];
[myImageView setBackgroundColor:[UIColor clearColor]];
self.pCellImageView = myImageView;
//**
//** Setup the Frame - Causes Redraw
//**
[self setFrameColor:[UIColor blackColor]];
[self setFrameLineWidth:myLineWidth];
[self setDrawFrame:YES];
}
-(void) setCellAsNormal
{
self.pCellKind = kLTWChaosBoardCellKindNormal;
[self setBackgroundColor:self.pCellUIColor];
[self removeAllSubviews];
[self addSubview:self.pCellImageView];
}
-(void) setCellAsPlayedWithPieceImage:(UIImage*) thePieceImage
{
UIImageView* myImageView;
CGRect myFrameRect;
myFrameRect = self.bounds;
myFrameRect = CGRectInset(myFrameRect,6,6);
myImageView = [[UIImageView alloc] initWithImage:thePieceImage];
[myImageView setFrame:myFrameRect];
[myImageView setBackgroundColor:[UIColor clearColor]];
//**
//** Add as Second Image View
//**
[self setBackgroundColor:self.pCellUIColor];
[self addSubview:myImageView];
