有没有办法这样做,除了使用自定义UIView与按钮返回作为导航栏？
解决方法
您可以将子视图添加到应用程序的基本视图
[[[UIApplication sharedApplication] keyWindow] addSubview:vMyCustomUIView];
为了确保只有当您的视图控制器可见时才会显示,您可以在viewDidAppear和viewDidDisappern委托方法中添加和删除它.这是一个示例,它将显示一个与其重叠的蓝色框.
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
vTestView = [[UIView alloc] initWithFrame:CGRectMake(10.0f,10.0f,100.0f,100.0f)];
vTestView.backgroundColor = [UIColor blueColor];
}
-(void)viewDidAppear:(BOOL)animated
{
[[[UIApplication sharedApplication] keyWindow] addSubview:vMyCustomUIView];
}
-(void)viewDidDisappear:(BOOL)animated
{
[vMyCustomUIView removeFromSuperview];
}
