你好,我是 iOS 的初学者我已经创建了自定义标签栏并添加了 UIbar 按钮项目,这些项目在 iOS 6 中正常工作,但在 iOS 7 GM 和 Xcode 5 中显示问题.....这是我的自定义标签栏代码......
TabBar=[[UITabBar alloc]initWithFrame:CGRectMake(0, 480, 320, 80)];
TabBar.autoresizingMask =UIViewContentModeTopRight | UIViewAutoresizingFlexibleWidth;
TabBar.tintColor=[UIColor blackColor];
UIButton *btn1=[[UIButton alloc]initWithFrame:CGRectMake(0, 0, 20, 20)];
[btn1 setTitle:@"Charge Details" forState:UIControlStateNormal];
btn1.titleLabel.font=[UIFont boldSystemFontOfSize:10.0];
[btn1 addTarget:self action:@selector(ChargeDetails) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *button1 = [[UIBarButtonItem alloc]initWithCustomView:btn1];
UIButton *btn2=[[UIButton alloc]initWithFrame:CGRectMake(0,0,40,40)];
btn2.titleLabel.font=[UIFont boldSystemFontOfSize:10.0];
[btn2 setTitle:@"View Contact Details" forState:UIControlStateNormal];
[btn2 addTarget:self action:@selector(ViewContactDetails) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *button2 = [[UIBarButtonItem alloc]initWithCustomView:btn2];
TabBar.items=[NSArray arrayWithObjects:button1,button2,nil];
[self.view addSubview:TabBar];
此代码在 iOS 6 中成功运行,但在 iOS 7 GM 中我有问题..实际上自定义 Tabbar 添加在视图上成功,但是当我们添加 barbutton 项目时,这显示错误...在这一行
TabBar.items=[NSArray arrayWithObjects:button1,button2,nil];
这是错误....
