copied!<p>U can change the color.But i do no about position.Create CustomAlert which inherits from Alert.In drawRect: u can specify color u want in CGContextSetRGBFillColor method. Here is implementation. @implementation CustomAlert</p> <pre><code>- (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code } return self; } // Method which will draw the actual view - (void)drawRect:(CGRect)rect { CGContextRef context=UIGraphicsGetCurrentContext(); UIColor *color = [UIColor purpleColor]; const CGFloat *arr= CGColorGetComponents(color.CGColor); CGContextSetRGBStrokeColor(context,0, 0, 0, 1.0); CGContextSetRGBFillColor(context, arr[0], arr[1], arr[2], 0.85); CGContextSetLineWidth(context, 1.0); addRoundedRectToPath(context, rect); // Drawing final path CGContextDrawPath(context, kCGPathFill); } - (void)dealloc { [super dealloc]; } @end static void addRoundedRectToPath(CGContextRef context, CGRect rect){ CGFloat radius = 10; CGFloat minx = CGRectGetMinX(rect), midx = CGRectGetMidX(rect), maxx = CGRectGetMaxX(rect); CGFloat miny = CGRectGetMinY(rect), midy = CGRectGetMidY(rect), maxy = CGRectGetMaxY(rect); CGContextMoveToPoint(context, minx, midy); // Add an arc through 2 to 3 CGContextAddArcToPoint(context, minx, miny, midx, miny, radius); // Add an arc through 4 to 5 CGContextAddArcToPoint(context, maxx, miny, maxx, midy, radius); // Add an arc through 6 to 7 CGContextAddArcToPoint(context, maxx, maxy, midx, maxy, radius); // Add an arc through 8 to 9 CGContextAddArcToPoint(context, minx, maxy, minx, midy, radius); CGContextClosePath(context); } </code></pre>
