I want to have a UIElement (any of UIView, UIButton, UILabel etc.) with custom shape lets say a triangle. How do you suggest to achieve it.
Thanks in advance.
Here is a sample of a UIView subclass (triangle):
@implementation TriangleView
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
}
return self;
}
- (void)drawRect:(CGRect)rect
{
// Drawing code
CGContextRef ctx = UIGraphicsGetCurrentContext();
CGContextBeginPath(ctx);
CGContextMoveToPoint (ctx, CGRectGetMinX(rect), CGRectGetMaxY(rect)); // top left
CGContextAddLineToPoint(ctx, CGRectGetMidX(rect), CGRectGetMinY(rect)); // mid right
CGContextAddLineToPoint(ctx, CGRectGetMaxX(rect), CGRectGetMaxY(rect)); // bottom left
CGContextClosePath(ctx);
CGContextSetRGBFillColor(ctx, 241/255.0, 241/255.0, 241/255.0, 1);
CGContextFillPath(ctx);
}
@end
