cgcontext

I want to draw line in table view cell so that I can place textfield & switch in single cell. I increased the height of cell. How can I draw line in cell? I have subclass of UIView which contains following code //Get the CGContext from this view CGContextRef context = UIGraphicsGetCurrentContext(); //Set the stroke (pen) color CGContextSetStrokeColorWithColor(context, [UIColor redColor].CGColor); //Set the width of the pen mark CGContextSetLineWidth(context, 1.0); // Draw a line //Start at this point CGContextMoveToPoint(context, 10.0, 30.0); //Give instructions to the CGContext //(move "pen"

Currently, I am having a graphical issue with drawing small dots. I notice that in most professional Calendar applications, the events calendar indentifier is a small dot whose color is the events calendar color. I am current at the point of my application where I need to draw a BETTER dot. Heres a photo of what I mean. It may not be noticeable here but the colored dot is pretty pixelated when its on my phone. I would like to remove the pixelation. I went through a tutorial from Ray Wenderlich's website: Ray Wenderlich Core Graphics . Here is what I got out of it for drawing the dot:

I'd like to draw a circle without filling (only border of the circle) step by step (like animated timer). 1 spin is equal 1 day (24 hours). I really don't know what to do. Steps I've made 1) I've tried https://github.com/danielamitay/DACircularProgress (it's too wide line of progress) 2) I've tried to draw a circle with many arcs. Can you put me some code please. I really confused. Thanks in advance. EDIT I'd like to use NSTimer because I have a button which allow user to stop drawning a circle. If user touch a button again - drawning will have to continue.

I'm trying to build an app that use layers, my app structure is UIView --> UIScrollView --> UIView --> LayersView (Custom UIView) --> UIImageView I want to add multiple layers to the LayersView, so I've build a custom CALayer that use UIBezierPath to draw a set of points. CALayerBezierPath.h #import <QuartzCore/QuartzCore.h> @interface CALayerBezierPath : CALayer { NSMutableArray *pointsArray; } @property (nonatomic, retain) NSMutableArray *pointsArray; - (void) initVariables; - (void) addNewPoints:(CGPoint)newPoint; @end CALayerBezierPath.m #import "CALayerBezierPath.h" @implementation

I have read some posts on this website about using drawInRect instead of the CGContext draw methods. It still draws it upside down? I thought using drawInRect would print it right side up with the coordinate system originating at the top left? -(void) drawImage:(UIImage*) image atX:(float) x andY:(float) y withWidth:(float) width andHeight:(float) height onContext:(CGContextRef) context{ UIGraphicsPushContext(context); [image drawInRect:CGRectMake(x, size.height-y-height, width, height)]; UIGraphicsPopContext(); } Notice I'm doing size.height-y-height and if I don't do that it doesn't go where

I have an app in which the screen continuously is capturing in background thread. Here is the code - (UIImage *) captureScreen { UIWindow *keyWindow = [[UIApplication sharedApplication] keyWindow]; CGRect rect = [keyWindow bounds]; UIGraphicsBeginImageContext(rect.size); CGContextRef context = UIGraphicsGetCurrentContext(); [[keyWindow layer] renderInContext:context]; UIImage *img = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); UIDeviceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation; if ((orientation ==
