Question

The colors on the main storyboard doesn't correspond to what the simulator is rendering. How come?

Answer 1

为了以防万一，请确保您没有更改任何视图或超级视图的alpha或代码中的颜色。

Answer 2

Here you can find a interesting explanation, but here are the basics:

1. You need to use the Digital Color Meter, with the option "Display in sRGB".

2. Pick the desired color from your design.

3. Apply the RGB values given by Digital Color Meter in the Interface Builder by previously choosing Generic RGB profile on the gear icon.
