Which is better to use if I simply wa开发者_运维百科nt a background image for a UIView
? I can accomplish this with either method, but which is more efficient? My hunch is that using a UIView
with colorWithPaternImage
is more efficient than using a UIImageView
. I'll be using this for each row in a UITableView
. Thanks! Matt
Completely disagree with boreas. There can be significant differences using colorWithPatternImage
vs other strategies depending on your requirements. For example, if you are using a UIScrollView
, using colorWithPatternImage
won't allow the image to scroll. It also generally depends on how large your view is because there is some tradeoff in performance vs memory footprint for different tiling strategies.
Check out WWDC 2010 session 104 which discusses tiling performance using CATiledLayer
. This is a good high-performance alternative to using either the built-in colorWithPatternImage
or CGContextDrawTiledImage
.
If your requirement is simply to display a single 320x480 static image, then there won't be any significant differences in the various strategies, but if your requirements are more complex then there certainly are.
Yes, there is a UIView
there anyway, so why bothering with another UIImageView
?
