Answer 1

这里是我的代码以实现图：

//Define the drawing path 
UIBezierPath *path1 = [[UIBezierPath alloc] init]; 
//path Move to start drawing position 
[path1 moveToPoint:CGPointMake(200, 100)]; 
//Draw a straight line from the starting position to（100, 200） 
[path1 addLineToPoint:CGPointMake(100, 100)]; 
//To draw a line from (100, 200) to (200, 200) 
[path1 addLineToPoint:CGPointMake(100, 200)]; 
//close path 
[path1 closePath]; 

CAShapeLayer *layer1 = [[CAShapeLayer alloc] init]; 
layer1.path = path1.CGPath; 
layer1.fillColor = [UIColor colorWithRed:0.88 green:0.87 blue:0.87 alpha:1.0].CGColor; 
[self.view.layer addSublayer:layer1]; 

UIBezierPath *path2 = [[UIBezierPath alloc] init]; 
[path2 moveToPoint:CGPointMake(200, 100)]; 
[path2 addLineToPoint:CGPointMake(200, 200)]; 
[path2 addLineToPoint:CGPointMake(100, 200)]; 
[path2 closePath]; 

CAShapeLayer *layer2 = [[CAShapeLayer alloc] init]; 
layer2.path = path2.CGPath; 
layer2.fillColor = [UIColor colorWithRed:0.89 green:0.57 blue:0.53 alpha:1.0].CGColor; 
[self.view.layer addSublayer:layer2]; 

这里是结果： result image
