How to change CAGradientLayer color points?


The startPoint and endPoint properties of a CAGradientLayer are defined in the “unit coordinate system”. In the unit coordinate system:

  • (0,0) corresponds to the smallest coordinates of the layer's bounds rectangle, which on iOS is its upper-left corner unless the layer has been transformed;
  • (1,1) corresponds to the largest coordinates of the layer's bounds rectangle, which on iOS is its lower-right corner unless the layer has been transformed.

Thus arranging your gradient the way you want should be this simple:

gradient.startPoint = CGPoint.zerogradient.endPoint = CGPoint(x: 1, y: 1)
