設置背景:
[_tabBar setBackgroundImage:[UIImage imageNamed:@"bg_tabbar"]];
設置某個Item選中的效果:
_tabBar.selectionIndicatorImage = [UIImage imageNamed:@"bar_item_selected"];//設置選中效果圖片
設置UITabBarItem文字顏色
forState:UIControlStateNormal];
[[UITabBarItem appearance] setTitleTextAttributes:@{ UITextAttributeTextColor : [UIColor whiteColor] }
forState:UIControlStateHighlighted];
設置UITabBarItem未選中與選中時的圖片:
[_hotTabItem setFinishedSelectedImage:[UIImage imageNamed:@"1_selected"] withFinishedUnselectedImage:[UIImage imageNamed:@"1"]];
[_searchTabItem setFinishedSelectedImage:[UIImage imageNamed:@"2_selected"] withFinishedUnselectedImage:[UIImage imageNamed:@"2"]];
[_userTabItem setFinishedSelectedImage:[UIImage imageNamed:@"3_selected"] withFinishedUnselectedImage:[UIImage imageNamed:@"3"]];
上述方法基本可以滿足了。
如果還不行可以自定義實現UITabBar。
bottomBar = [[UITabBaralloc] initWithFrame:CGRectMake(0,CGRectGetMaxY(sframe)-25,self.view.frame.size.width,0)];//初始隱藏bottomBar
//[bottomBar setDelegate:self];
[self.viewaddSubview:bottomBar];
//按鈕
CGFloat btnWidth = (sframe.size.width-165)/2;//兩個按鈕
CGFloat btnTop =0;//sframe.size.height-barHeight;
CGFloat _barHeight = dHeightBar;
MU_tabButton* btn1 = [[MU_tabButtonalloc] initWithFrame:CGRectMake(0, btnTop, btnWidth, _barHeight)];
[btn1 addTarget:selfaction:@selector(selectAllClicked:)forControlEvents:UIControlEventTouchUpInside];
[btn1 setBgImg:dImgTabBgandIconImg:dImgSelectAllandTitle:@"全選"withColor:dColorTabTextNormalforState:UIControlStateNormal];
MU_tabButton* btn2 = [[MU_tabButtonalloc] initWithFrame:CGRectMake(btnWidth, btnTop, btnWidth, _barHeight)];
[btn2 setBackgroundImage:dImgTabClickedforState:UIControlStateHighlighted];
[btn2 addTarget:selfaction:@selector(deleteClicked:)forControlEvents:UIControlEventTouchUpInside];
[btn2 setBgImg:dImgTabBgandIconImg:dImgDeleteandTitle:@"刪除"withColor:dColorTabTextNormalforState:UIControlStateNormal];
[bottomBaraddSubview:btn1];
[bottomBaraddSubview:btn2];
///////////其中MU_tabButton 爲自定義類型- (id)initWithFrame:(CGRect)frame
{
self = [superinitWithFrame:frame];
if (self) {
// Initialization code
CGFloat iconHeight = frame.size.height*3/5;
//文字
titleLabel = [[UILabelalloc] initWithFrame:CGRectMake(0, iconHeight, frame.size.width, frame.size.height- iconHeight)];
titleLabel.backgroundColor = [UIColorclearColor];
titleLabel.textColor = [UIColorwhiteColor];
titleLabel.textAlignment =NSTextAlignmentCenter;
titleLabel.font = [UIFontsystemFontOfSize:13];
[selfaddSubview:titleLabel];
//圖標
CGFloat iconGap = 3;
CGFloat iconSize = iconHeight - iconGap;//圖標大小
iconView = [[UIImageViewalloc] initWithFrame:CGRectMake((frame.size.width- iconSize)/2, iconGap, iconSize, iconSize)];
[selfaddSubview:iconView];
}
return self;
}
-(void)setBgImg:(UIImage *)bgImg andIconImg:(UIImage *)img andTitle:(NSString *)title withColor:(UIColor*)tColor forState:(UIControlState)state
{
[selfsetBackgroundImage:bgImg forState:UIControlStateNormal];
iconView.image = img;
titleLabel.text = title;
titleLabel.textColor = tColor;
