How to set the Radius Corners to View using DrawRect Method? - objective-c

Question

using DrawRect method to draw a rectangle view. I have to set the radius corners of that particular rectangle view.I have written to draw a rectangle view below.
- (void)drawRect:(CGRect)rect {
int coordinate_x=60,coordinate_y=120,width=200,height=295;
CGContextRef context = UIGraphicsGetCurrentContext();
CGRect drawTank = {coordinate_x, coordinate_y, width, height};
CGColorRef blackColor=[UIColor blackColor].CGColor;
CGContextSetRGBStrokeColor(context, 0, 0, 255, 1);
CGContextSetLineWidth(context, 1.0);
CGContextSetStrokeColorWithColor(context, blackColor);
CGContextStrokeRect(context, drawTank);
}
And i have to use fill the view and empty view use code below.
CGRect emptyTank = CGRectMake(coordinate_x, coordinate_y, width, height *(1-filledPercentage));
CGRect fullTank = CGRectMake(coordinate_x, coordinate_y+height *(1-filledPercentage),width, height * filledPercentage);
how to set the radius corner to the particular view. please help me.
Thanks in Advance.

Answer 1

you can simply set the corner radius of a UIView with:
view.layer.cornerRadius = 5;
If you are using beizer path , you can set corner radius with the following code:
UIBezierPath* rectanglePath = [UIBezierPath bezierPathWithRoundedRect: CGRectMake(55, 30, 133, 51) cornerRadius: 5];
[UIColor.grayColor setFill];
[rectanglePath fill];
within the drawRect method:
- (void)drawRect: (CGRect)frame
{
//// Rectangle Drawing
UIBezierPath* rectanglePath = [UIBezierPath bezierPathWithRoundedRect: CGRectMake(CGRectGetMinX(frame) + 40, CGRectGetMinY(frame) + 21, 133, 51) cornerRadius: 7];
[UIColor.grayColor setFill];
[rectanglePath fill];
}
