没有圆边的 Iphone 自定义 UITabBarItem

Question

我尝试自定义一个uitabbar

我扩展了 uitabbar 项目，现在里面有一个自定义图像，但我无法摆脱圆边。

代码:

@interface CustomTabBarItem : UITabBarItem  
{
    UIImage *customHighlightedImage;
}

@property (nonatomic, retain) UIImage *customHighlightedImage;

@end

@implementation CustomTabBarItem

@synthesize customHighlightedImage;

- (void) dealloc
{
    [customHighlightedImage release]; customHighlightedImage=nil;
    [super dealloc];
}

-(UIImage *) selectedImage
{
    return self.customHighlightedImage;
}

@end

也许 somoen 知道如何摆脱圆角矩形

图片周围

这很脏 - 但有效并获得批准:

• 调整标签栏的大小
• 使用自己尺寸的图片

在选项卡 Controller 设置中

    tabController   = [[UITabBarController alloc] init];
tabController.view.frame = CGRectMake(0, 72, 320, 480 - (82));
tabController.delegate = self;
UIImageView *bgImageView;
bgImageView = [ [ UIImageView alloc ] initWithImage: [UIImage imageNamed:TABBAR_BACKGROUND]];
bgImageView.frame = CGRectMake(0, -11, 320, 60);

[[tabController tabBar] addSubview:bgImageView];
[[tabController tabBar] sendSubviewToBack:bgImageView];
tabController.tabBar.frame = CGRectMake(0, 460 - (59 + 52 - 11), 320, 49);
[bgImageView release];

[window addSubview:tabController.view];

在tabviewcontroller1的初始化方法中

   - (id) init
{
    if(self = [super init])
    {       
        CustomTabBarItem *tabItem = [[CustomTabBarItem alloc]
                                     initWithTitle:@"" image:nil tag:0];

        tabItem.customHighlightedImage=[UIImage imageNamed:TABBAR_TAB_1_ACTIVE];
        tabItem.customStdImage=[UIImage imageNamed:TABBAR_TAB_1_DEFAULT];       

        self.tabBarItem=tabItem;
        [tabItem release]; 
        tabItem=nil;
    }

return self;
}

自定义标签栏看起来像

    @interface CustomTabBarItem : UITabBarItem  
    {
        UIImage *customHighlightedImage;
        UIImage *customStdImage;
    }

    @property (nonatomic, retain) UIImage *customHighlightedImage;
    @property (nonatomic, retain) UIImage *customStdImage;

    @end

#import "CustomTabBarItem.h"


@implementation CustomTabBarItem

@synthesize customHighlightedImage;
@synthesize customStdImage;

- (void) dealloc
{
    [customHighlightedImage release]; customHighlightedImage=nil;
    [customStdImage release]; customStdImage=nil;   
    [super dealloc];
}

-(UIImage *) selectedImage
{
    return self.customHighlightedImage;
}

-(UIImage *) unselectedImage
{
    return self.customStdImage;
}

@end
