こんにちは、iOS の初心者です。カスタム タブバーを作成し、iOS 6 では正常に動作する UIbar ボタン項目を追加しましたが、iOS 7 GM と Xcode 5 では問題が表示されます..... これはカスタム タブバーのコードです ...
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];
このコードは iOS 6 で正常に動作しますが、iOS 7 GM では問題があります。
TabBar.items=[NSArray arrayWithObjects:button1,button2,nil];
これはエラーです....
