Description
Running on the iphone, setting a background gradient color to black does not work, Setting it to 000001 does work however.
Code:
var win = Ti.UI.currentWindow;
var view = Titanium.UI.createView({
top:0,
left:0,
//height:height,
//width:width,
backgroundGradient:{
type:'linear',
colors:[{color:'#50FFFF',position:0.0},{color:'#000000',position:1.0}]
}
});
win.add(view);

Apparently the reason why this isn't working is because [UIColor blackColor]'s color space model is kCGColorSpaceModelMonochrome.
CAGradientLayer does not accept colors that are in the kCGColorSpaceMonochrome color space model.
The fix for this is to check if the color space is kcGColorSpaceModelMonochrome, and if it is, re-assign the gradient's color to the RGB representation of the color by using UIColor's colorWithRed:green:blue:alpha: method.
Here's a screenshot of it in action:
