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，现在它有一个自定义的图像，但我不能摆脱圆角的边缘。

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

也许索莫恩知道如何去掉圆角直齿。

在图像周围

提前谢谢你，亚历克斯

感谢您使用自定义选项卡栏项目解决了此问题

尚未获得苹果公司的批准。

进入tabController1.m

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

        tabItem.customHighlightedImage=[UIImage imageNamed:TABBAR_TAB_4_ACTIVE];
        tabItem.customStdImage=[UIImage imageNamed:TABBAR_TAB_4_DEFAULT];       

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

cutom tabbaritem：

@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

这是脏的-但工作并获得批准：

• 调整选项卡栏大小
• 使用自己大小的图像

在标签控制器设置中

    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;
}

自定义选项卡栏看起来像

    @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

重要信息：

我是iphone开发的新手，你可以用这种方式做的不那么麻烦。此外，我也同意这一点，这并不意味着你也会自动同意。

将具有圆角的视图上的cornerRadius设置为0：

view.layer.cornerRadius = 0;

此外，您可能需要添加一个#include来获取CALayer声明：

#import <QuartzCore/QuartzCore.h>
