UItabBar设置的一些设置 合一些效果实现 设置badgeValue的方法封装

ios默认的样式不太适合我们的应用，可以通过一下方法设置相关属性：

设置背景：

[_tabBar setBackgroundImage:[UIImage imageNamed:@"bg_tabbar"]];

设置某个Item选中的效果：

_tabBar.selectionIndicatorImage = [UIImage imageNamed:@"bar_item_selected"];//设置选中效果图片

设置UITabBarItem文字颜色
[[UITabBarItem appearance] setTitleTextAttributes:@{ UITextAttributeTextColor
: [UIColor whiteColor] }

forState:UIControlStateNormal];

[[UITabBarItem appearance] setTitleTextAttributes:@{ UITextAttributeTextColor
: [UIColor whiteColor] }

forState:UIControlStateHighlighted];

设置UITabBarItem未选中与选中时的图片：

[_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"]];

上述方法基本可以满足了。

如果还不行可以自定义实现UITabBar。

bottomBar = [[UITabBaralloc]
initWithFrame:CGRectMake(0,CGRectGetMaxY(sframe)-25,self.view.frame.size.width,0)];//初始隐藏bottomBar

//[bottomBar setDelegate:self];
[self.viewaddSubview:bottomBar];
//按钮
CGFloat btnWidth = (sframe.size.width-165)/2;//两个按钮

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:@"全选"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:@"删除"withColor:dColorTabTextNormalforState:UIControlStateNormal];
[bottomBaraddSubview:btn1];
[bottomBaraddSubview:btn2];
///////////其中MU_tabButton 为自定义类型

主要属性包含如下：

- (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];
//图标
CGFloat iconGap =
3;
CGFloat iconSize = iconHeight - iconGap;//图标大小
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;
}

-(void)setBadgeValue:(NSString*)val atTabIndex:(int)index
{

// UITabBarItem* tab = [[bottomBtnBar items] objectAtIndex:2*index];

UITabBarItem* tab = [[bottomBtnBar
items] objectAtIndex:index];

if ([val integerValue] <=
0) {
tab.badgeValue =
nil;
}

else
{
tab.badgeValue = val;
}
}

-(NSString*)getBadgeValueAtIndex:(int)index
{

UITabBarItem* tab = [[bottomBtnBar
items] objectAtIndex:index];

return tab.badgeValue;
}
