Do I need to suffix @3x in UIImage imageNamed?

Question

There are iPhone 6 and iPhone 6 plus device available from apple.

• I have three pics including @2x and @3x. When I load image using UIImage imageNamed:.
• Do I need to add @3x ad the end of file? My naming convention is pic.png, [email protected], [email protected].
• Do I need to do like first check the running device is iPhone 6 and then [UIImage imageNamed:@"[email protected]"] or just [UIImage imageNamed:@"pic"] and the device will automatically use the right image for the right device?

Answer 1

Sol: [UIImage imageNamed:@"pic"] is enough instead of [UIImage imageNamed:@"pic.png"].

Reason:

• Device automatically detect [email protected] & [email protected] once you added into you project.
• If you not added any [email protected] or [email protected] image means device will load pic.png automatically.
• So you just add this line [UIImage imageNamed:@"pic"] in your project.

Answer 2

[UIImage imageNamed:@"pic"]

is enough.

Suffixes (@2x for iPhone 4 to 6 and @3x for iPhone 6 plus) are added automatically if image with this suffix is found.
