新建一个类继承UITabBarController：
– (
id
) init
{
self
= [
super
init
];
if
(
self
) {
//
方法一
UIImageView
*img = [[
UIImageView
alloc
]
initWithImage
:[
UIImage
imageNamed
:
@”bg.png”
]];
img.
frame
=
CGRectMake
(
0
,
0
,
self
.
tabBar
.
frame
.
size
.
width
,
self
.
tabBar
.
frame
.
size
.
height
);
img.
contentMode
=
UIViewContentModeScaleToFill
;
//img.frame = CGRectOffset(img.frame, 0, 1);
[[
self
tabBar
]
insertSubview
:img
atIndex
:
0
];
[img
release
];
//
方法二

frame =
CGRectMake
(

UIView
*view = [[

UIImage
*tabBarBackgroundImage = [
UIImage

];
UIColor
*color = [[

initWithPatternImage
:tabBarBackgroundImage];
[view
setBackgroundColor
:color];
[color
release
];
[[

insertSubview
:view
atIndex
:
0

[view

}
return
