Why do i always get this log, Infinite source rectangle to drawImage method, is this such an error or there's something wrong with the code algorithm. I don't really understand about this, and i can't find any useful information on google. Hope i can find the answer on this site.
sorry, this is my drawRect method :
- (void)drawRect:(NSRect)rect {
// Drawing code here.
// drawBackground
[[NSColor colorWithCalibratedRed:0 green:0 blue:0 alpha:1.0] set];
[NSBezierPath fillRect:[self bounds]];
if (myCIImage != nil) {
//Create the CIContext
CIContext *context = [[NSGraphicsContext currentContext] CIContext];
//scale to fit in view rect
CIImage *drawnImage;
if (previewFilter == YES) {
drawnImage = [previewImage imageByApplyingTransform:[self imageTransformToFitView]];
} else {
drawnImage = [myCIImage imageByApplyingTransform:[self imageTransformToFitView]];
}
// center in view rect
NSRect viewBounds = [self bounds];
CGRect sRect = [drawnImage extent];
CGRect dRect = sRect;
dRect.origin.x = viewBounds.origin.x + (viewBounds.size.width - sRect.size.width)/2;
dRect.origin.y = viewBounds.origin.y + (viewBounds.size.height - sRect.size.height)/2;
[context drawImage:drawnImage
inRect:dRect
fromRect:sRect];
}
}
thanks -
I think that means the dimensions of sRect contain some infinite numbers. Have you run this under the debugger and inspected the values in sRect?
Probably the transform you apply to the image is wrong.

I'm trying to draw some things on the background of my windows. Therefore I subclassed the NSView of the window and added some drawing code like this:
- (void)drawRect:(NSRect)dirtyRect {
float color = 0.95;
[[NSColor colorWithDeviceRed:color green:color blue:color alpha:1.0] set];
NSRectFill(NSMakeRect(320, 0, 220, NSHeight(dirtyRect)-60));
}
This works great, but as soon as I open a NSComboBox or if I activate a checkbox, the background of these elements erases my just drawn rect.
I don't understand this, because checking for example the checkbox causes, that drawRect is called (I added a NSLog). Only resizing the window draws my rect again.
EDIT:
here is a screenshot of the problem:
I sometimes face the same problem. I think the following is what I use.

I have an UIView which I created and set background color to white. This view contains UILabel, which is a class called BubbleView. (Sorry I cannot add a picture because you need reputation 10+ :(
PROBLEM:
1. The following code produces a gray Label with rounded corner with gray-border square corner tips. This is because the UIView produces the square corner tips. The UILabel is rounded. Please note that I already set the background of UIView to white.
2. My text string of the UILabel is hiding behind UIView, so it is not displayed.
I'd love to show you pictures, but I am new and I cannot add pictures until I get to 10+ reputations.

Here is my code for setting the text and the view:
BubbleView:
- (void)drawRect:(CGRect)rect
{
const CGFloat boxWidth = self.bubbleWidth;
const CGFloat boxHeight = self.bubbleHeight;
NSLog(#"text, width, height: %#, %f, %f", self.text, self.bubbleWidth, self.bubbleHeight);
CGRect boxRect = CGRectMake(
roundf(self.bounds.size.width - boxWidth) / 2.0f,
roundf(self.bounds.size.height - boxHeight) / 2.0f,
boxWidth,
boxHeight);
UIBezierPath *roundedRect = [UIBezierPath bezierPathWithRoundedRect:boxRect cornerRadius:14.0f];
[[UIColor colorWithWhite:0.3f alpha:0.8f] setFill];
[roundedRect fill];
NSDictionary *attributes = #{
NSFontAttributeName : [UIFont systemFontOfSize:16.0f],
NSForegroundColorAttributeName : [UIColor whiteColor]
};
CGPoint textPoint = CGPointMake(
self.center.x+boxWidth/2,
self.center.y+boxHeight/2);
NSLog(#"text point origin: %f, %f", textPoint.x, textPoint.y);
[self.text drawAtPoint:textPoint withAttributes:attributes];
}
Main View Controller:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.view.backgroundColor = [UIColor whiteColor];
[self setText];
}
-(void) viewDidLayoutSubviews {
[super viewDidLayoutSubviews];
[self setText];
}
- (void) setText
{
NSString *textR = #"I need this text to show up on autolayout so that i could continue working";
UIFont* font = [UIFont fontWithName:#"HelveticaNeue" size:14.0f];
CGSize constraint = CGSizeMake(250,9999);
CGRect textRect = [textR boundingRectWithSize:constraint
options:NSStringDrawingUsesLineFragmentOrigin
attributes:#{NSFontAttributeName:font}
context:nil];
BubbleView *hostView = [[BubbleView alloc] initWithFrame:CGRectMake(20.0f, 160.0f, textRect.size.width+20, textRect.size.height+20)];
hostView.bubbleWidth = textRect.size.width+20;
hostView.bubbleHeight = textRect.size.height+20;
hostView.text = textR;
hostView.layer.cornerRadius = 10.0f;
self.view.layer.masksToBounds = TRUE;
[hostView drawRect:textRect];
hostView.backgroundColor = [UIColor whiteColor];
self.detailsView = hostView;
//self.detailsView.backgroundColor = [UIColor whiteColor];
NSLog(#"size: %f, %f", textRect.size.width, textRect.size.height);
NSLog(#"origin: %f, %f - size: %f, %f, backgroundColor: #%#", self.detailsView.frame.origin.x, self.detailsView.frame.origin.y, self.detailsView.frame.size.width, self.detailsView.frame.size.height, self.detailsView.backgroundColor);
[self.view addSubview:self.detailsView];
self.hostSays.text = textR;
self.hostSays.textColor = [UIColor blueColor];
[self.view layoutSubviews];
}
SOLUTION (ONLY 1 PART):
OK so I managed to solve half of my problems. I had to add the following code in my BubbleView class (inside - (id)initWithFrame:(CGRect)frame). This got rid of the square angles! (I think Wain was the one who suggested this but I might've misunderstood him)...
[self setOpaque:NO];
[self setBackgroundColor:[UIColor clearColor]];
So...still have the other part 2 of problem to solve and I'm hoping someone has run into this issue before!
Set the background colour of the view and add the label as a subview. Set the frame to get your required padding. Do not implement drawRect.
Now, the view will draw the background colour and the label automatically and the label will draw the text (with its background colour and border settings).
I know when I create custom buttons I need to setMasksToBounds
+ (void) addBorderToButtons:(UIButton *) btn
{
// Round button corners
CALayer *btnLayer = [btn layer];
[btnLayer setMasksToBounds:YES];
[btnLayer setCornerRadius:15.0f];
// Apply a 1 pixel, black border around Buy Button
[btnLayer setBorderWidth:1.5f];
[btnLayer setBorderColor:[[UIColor blackColor] CGColor]];
}
Setting this changes
To this
If you want to save your coding approach you strongly need to add [super drawRect:rect] in your drawRect: method
- (void)drawRect:(CGRect)rect{
[super drawRect:rect];
YOUR CODE
}
In this case you will see your text in UILabel.
Also you should not call drawRect: directly. It will be called automatically in runtime:
BubbleView *hostView =
[[BubbleView alloc] initWithFrame:CGRectMake(20.0f,
160.0f,
textRect.size.width+20,
textRect.size.height+20)];
hostView.bubbleWidth = textRect.size.width+20;
hostView.bubbleHeight = textRect.size.height+20;
hostView.text = textR;
// hostView.layer.cornerRadius = 10.0f;
// self.view.layer.masksToBounds = TRUE;
// [hostView drawRect:textRect];
// hostView.backgroundColor = [UIColor whiteColor];
self.detailsView = hostView;
The NSImage colorWithPatternImage method tiles images from the bottom. Can can I tiles them from the top instead ?
+ (NSColor *)colorWithPatternImage:(NSImage *)image Parameters image
The image to use as the pattern for the color object. The image is
tiled starting at the bottom of the window. The image is not scaled.
This is my code in my subclass of IKImageBrowserView, which is the view inside NSScrollView in my app.
- (void)drawRect:(NSRect)rect
{
NSImage * backgroundImage = [NSImage imageNamed:#"deliciousLibrary.png"];
[backgroundImage setSize:NSMakeSize(459 * bgImageSize, 91 * bgImageSize)];
[[NSColor colorWithPatternImage:backgroundImage] set];
NSRectFill(rect);
[super drawRect:rect];
}
thanks
UPDATE:
I've found on the internet this solution. But in my case it doesn't work because the image is not scrolling anymore in my NSScrollView.
- (void)drawRect:(NSRect)dirtyRect {
NSGraphicsContext* theContext = [NSGraphicsContext currentContext];
[theContext saveGraphicsState];
[[NSGraphicsContext currentContext] setPatternPhase:NSMakePoint(0,[self frame].size.height)];
[self.customBackgroundColour set];
NSRectFill([self bounds]);
[theContext restoreGraphicsState];
}
This is the solution to my problem. Amazingly simple.
float yOffset = NSMaxY([self convertRect:[self frame] toView:nil]);
[[NSGraphicsContext currentContext] setPatternPhase:NSMakePoint(0,yOffset)];
Here's the accepted answer in Swift 5:
let yOffset = NSMaxY(self.convert(self.frame, to: nil))
NSGraphicsContext.current?.patternPhase = NSMakePoint(0, yOffset)
...and a simple example implementation:
class MyPatternedView: NSView {
override func draw(_ dirtyRect: NSRect) {
// Make the pattern tile repeat from the top of the view.
let yOffset = NSMaxY(self.convert(self.frame, to: nil))
NSGraphicsContext.current?.patternPhase = NSMakePoint(0, yOffset)
if let image = NSImage(named: "Bricks") {
let color = NSColor.init(patternImage: image)
color.setFill()
dirtyRect.fill()
}
super.draw(dirtyRect)
}
}
I've been trying to display a NSImage on a CALayer. Then I realised I need to convert it to a CGImage apparently, then display it...
I have this code which doesn't seem to be working
CALayer *layer = [CALayer layer];
NSImage *finderIcon = [[NSWorkspace sharedWorkspace] iconForFileType:NSFileTypeForHFSTypeCode(kFinderIcon)];
[finderIcon setSize:(NSSize){ 128.0f, 128.0f }];
CGImageSourceRef source;
source = CGImageSourceCreateWithData((CFDataRef)finderIcon, NULL);
CGImageRef finalIcon = CGImageSourceCreateImageAtIndex(source, 0, NULL);
layer.bounds = CGRectMake(128.0f, 128.0f, 4, 4);
layer.position = CGPointMake(128.0f, 128.0f);
layer.contents = finalIcon;
// Insert the layer into the root layer
[mainLayer addSublayer:layer];
Why? How can I get this to work?
From the comments: Actually, if you're on 10.6, you can also just set the CALayer's contents to an NSImage rather than a CGImageRef...
If you're on OS X 10.6 or later, take a look at NSImage's CGImageForProposedRect:context:hints: method.
If you're not, I've got this in a category on NSImage:
-(CGImageRef)CGImage
{
CGContextRef bitmapCtx = CGBitmapContextCreate(NULL/*data - pass NULL to let CG allocate the memory*/,
[self size].width,
[self size].height,
8 /*bitsPerComponent*/,
0 /*bytesPerRow - CG will calculate it for you if it's allocating the data. This might get padded out a bit for better alignment*/,
[[NSColorSpace genericRGBColorSpace] CGColorSpace],
kCGBitmapByteOrder32Host|kCGImageAlphaPremultipliedFirst);
[NSGraphicsContext saveGraphicsState];
[NSGraphicsContext setCurrentContext:[NSGraphicsContext graphicsContextWithGraphicsPort:bitmapCtx flipped:NO]];
[self drawInRect:NSMakeRect(0,0, [self size].width, [self size].height) fromRect:NSZeroRect operation:NSCompositeCopy fraction:1.0];
[NSGraphicsContext restoreGraphicsState];
CGImageRef cgImage = CGBitmapContextCreateImage(bitmapCtx);
CGContextRelease(bitmapCtx);
return (CGImageRef)[(id)cgImage autorelease];
}
I think I wrote this myself. But it's entirely possible that I ripped it off from somewhere else like Stack Overflow. It's an older personal project and I don't really remember.
Here's some code which may help you - I sure hope the formatting of this does not get all messed up like it appears is going to happen - all I can offer is that this works for me.
// -------------------------------------------------------------------------------------

root.layoutManager = [CAConstraintLayoutManager layoutManager];
// create a new layer which will contain ALL our sublayers

mContainer.bounds = root.bounds;

// insert layer on the bottom of the stack so it is behind the controls
[root insertSublayer:mContainer atIndex:0];
// make it resize when its superlayer does
root.autoresizingMask = kCALayerWidthSizable | kCALayerHeightSizable;
// make it resize when its superlayer does
mContainer.autoresizingMask = kCALayerWidthSizable | kCALayerHeightSizable;

then you can set it:

I am new to programing and any help is appreciated. I am trying to change the background color of a button once it has been pressed. I have tried setBackgroundColor without success. I am not sure that it is compatible with UIButton. Is there any way to programatically accomplish such a task? All thoughts and suggestions are appreciated.
I woudl suggest creating a simple image that contains the background color you want and setting that via the existing methods in the UIButton. (check Wrights Answer for the doc link).
UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom];
NSString* fileLocation = [[NSBundle mainBundle] pathForResource:#"buttonBG" ofType:#"png"];
UIImage* bgImage = [UIImage imageWithContentsOfFile:fileLocation];
if (bgImage != nil) { // check if the image was actually set
[button setBackgroundImage:bgImage forState:UIControlStateHighlighted];
} else {
NSLog(#"Error trying to read the background image");
}
That should do the trick. There might be an even better way to create the necessary image on the fly, but that's stuff I'm not firm in.
[edit: a bit more verbose code ]
Assuming you have an unadorned custom button with a title of "On" for the normal state:
- (IBAction) toggleButtonState {
if ([toggleButton titleForState:UIControlStateNormal] == #"On") {
[toggleButton setTitle: #"Off" forState:UIControlStateNormal];
[toggleButton setBackgroundColor:[UIColor redColor]];
}
else {
[toggleButton setTitle: #"On" forState:UIControlStateNormal];
[toggleButton setBackgroundColor:[UIColor greenColor]];
}
}
All the other buttons have an image placed in front of the view, so at most you'll see the corners change if the image doesn't completely fill the space.
I'd also suggest using an image, but for learning purposes, this will work.
Ive just been having the same issue and ended up using a UIButton subclass to tackle the issue. I used gradients simply because it looked a bit better if you have no need for them you can simply remove them. I have explained the process I used and included the full code at the bottom of the post.
Firstly add properties for the layers.I created two layers one for the base gradient and one for a gloss to add a little bit of style.
#interface gradientButton()
#property (nonatomic, strong) CAGradientLayer* gradientLayer;
#property (nonatomic, strong) CAGradientLayer* glossyLayer;
#end
Then either in -(void)awakeFromNib or in -(id)initWithFrame:(CGRect)frame
,depending on if you will load from storyboard or code respectively, configure the gradients and add the layers, round your corners off and customize the font highlight color.
-(void)awakeFromNib
{
_gradientLayer = [[CAGradientLayer alloc] init];
_gradientLayer.bounds = self.bounds;
_gradientLayer.position = CGPointMake(self.bounds.size.width/2, self.bounds.size.height/2);
[self.layer insertSublayer:_gradientLayer atIndex:0];
self.layer.cornerRadius = 5.0f;
self.layer.masksToBounds = YES;
self.layer.borderWidth = 1.0f;
_glossyLayer = [[CAGradientLayer alloc] init];
_glossyLayer.bounds = CGRectMake(0, 0, self.bounds.size.width, self.bounds.size.height/2);
_glossyLayer.position = CGPointMake(self.bounds.size.width/2, self.bounds.size.height/4);
[self.layer addSublayer:_glossyLayer];
[self setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[self setTitleColor:[UIColor yellowColor] forState:UIControlStateHighlighted];
}
Next, override - (void)drawRect:(CGRect)rect to apply your layers and define your colors.
#define GRADIENT_TOP [UIColor colorWithRed:38.0/255.0 green:78.0/255.0 blue:54.0/255.0 alpha:1]
#define GRADIENT_BOTTOM [UIColor colorWithRed:44.0/255.0 green:71.0/255.0 blue:56.0/255.0 alpha:1]
#define GLOSS_TOP [UIColor colorWithRed:0.70f green:0.70f blue:0.70f alpha:0.95f]
#define GLOSS_BOTTOM [UIColor colorWithRed:0.70f green:0.70f blue:0.70f alpha:0.35f]
#define GRADIENT_SELECTED_TOP [UIColor colorWithRed:138.0/255.0 green:178.0/255.0 blue:154.0/255.0 alpha:1]
#define GRADIENT_SELECTED_BOTTOM [UIColor colorWithRed:114.0/255.0 green:171.0/255.0 blue:156.0/255.0 alpha:1]
- (void)drawRect:(CGRect)rect
{
[_gradientLayer setColors:#[(id)[GRADIENT_TOP CGColor],(id)[GRADIENT_BOTTOM CGColor]]];
[_glossyLayer setColors:#[(id)[GLOSS_TOP CGColor], (id)[GLOSS_BOTTOM CGColor]]];
[super drawRect:rect];
}
Finally, and the bit we've all been waiting for, override -(void)setHighlighted:(BOOL)highlighted{
so we can apply the highlight effect were looking for.
-(void)setHighlighted:(BOOL)highlighted{
[super setHighlighted:highlighted];
if(highlighted)
[_gradientLayer setColors:#[(id)[GRADIENT_SELECTED_TOP CGColor],(id)[GRADIENT_SELECTED_BOTTOM CGColor]]];
else
[_gradientLayer setColors:#[(id)[GRADIENT_TOP CGColor],(id)[GRADIENT_BOTTOM CGColor]]];
}
There we have it, now just drag out a UIButton modify the class and your all good. Heres the full Implementation so you can copy it straight out. http://pastebin.com/nUVeujyp
Check out the UIButton Class Reference.
Regular UIButtons do not have the backgroundColor option.
My suggestion would to use the UISegmentedControl, which has the tinColor option.
I have created a subclass which get background color and creates an UIImage for each state.
For me it's more useful a subclass instead a category, so that's up to you.

In fact, you can use it in the storyboard, changing the class and setting de background color in the view.
