Simple gradient drawing for iOS

The first few weeks of the music list in the project to add a shadow to the left to make a smooth effect.

With a very simple gradient implementation:

The code is as follows:

1-(Cagradientlayer *) Shadowofmusic: (float) frameheight 2 {3     cagradientlayer *newshadow = [[[Cagradientlayer Alloc] INIT] autorelease]; 4     CGRect newshadowframe = CGRectMake (0, 0, 5, frameheight); 5     newshadow.frame = newshadowframe; 6     // Add color combinations of gradients 7     newshadow.colors = [Nsarray arraywithobjects: (ID) [Uicolor blackcolor]. Cgcolor, (ID) [Uicolor clearcolor]. Cgcolor,nil]; 8     newshadow.startpoint=cgpointmake (0.0, 0.5); 9     Newshadow.endpoint=cgpointmake (1.0, 0.5);     NEWSHADOW;11}

Of course, this also requires you to set the transparency in the call, otherwise the effect is not good.
