[英]How to add the view to whole screen
我有一個2 vc,可以從一個屏幕推到另一個屏幕。在我的vc2中,我以編程方式添加了導航欄標題,bar button。 但是,當我添加視圖時,從頂部減少了10點。 沒有完全顯示。 我嘗試了所有可能性。 附加圖像:
在我的vc2中:
- (void)viewDidLoad {
[super viewDidLoad];
_menuView.hidden = YES;
[self navItems];
}
-(void)navItems{
UIImage* filterImage = [UIImage imageNamed:@"filter.png"];
CGRect frameimg = CGRectMake(0,0, 15,15);
filterBtn = [[UIButton alloc] initWithFrame:frameimg];
[filterBtn setBackgroundImage:filterImage forState:UIControlStateNormal];
[filterBtn addTarget:self action:@selector(MenuTap:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *filter =[[UIBarButtonItem alloc] initWithCustomView:filterBtn];
self.navigationItem.rightBarButtonItem = filter;
self.title = @"Demo";
self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"" style:UIBarButtonItemStylePlain target:nil action:nil];
}
- (IBAction)MenuTap:(id)sender
{
_menuView.hidden = NO;
//1
// [self.navigationController.view addSubview:_menuView];
// [self.view addSubview:_menuView];
//2
// UIWindow *window = [[[UIApplication sharedApplication] delegate] window];
// [window addSubview: _menuView];
//
//3
// UIWindow *currentWindow = [UIApplication sharedApplication].keyWindow;
//[currentWindow addSubview:_menuView];
//4
//[[UIApplication sharedApplication].windows.lastObject addSubview:_menuView];
//5
// self.navigationController.navigationBar.layer.zPosition = -1;
//[self.view addSubview:_menuView];
}
我正在使用@ Anbu.Karthic解決方案進行更新。
在(IBAction)MenuTap:(id)sender
使用以下代碼更新代碼。 它會工作。 我努力了。
- (IBAction)MenuTap:(id)sender
{
_menuView.hidden = NO;
[self.navigationController.view addSubview:_menuView];
_menuView.frame = [[UIScreen mainScreen] bounds];
}
根據此處的問題添加了詳細答案,如果要顯示在狀態欄下方,則需要首先獲取狀態欄的高度,然后在y位置添加所需的位置。
- (IBAction)MenuTap:(id)sender
{
_menuView.hidden = NO;
//initially getStatusbar height
float statusBarHeight = [self statusBarHeight];
// assign your subview to window bounds
_menuView.frame = [[UIScreen mainScreen] bounds];
CGRect frameRect = _menuView.frame;
// convert your y- coordinates based on your need
frameRect.origin.y = statusBarHeight;
_menuView.frame = frameRect;
[self.navigationController.view addSubview:_menuView];
}
-(float) statusBarHeight
{
CGSize statusBarSize = [[UIApplication sharedApplication] statusBarFrame].size;
return MIN(statusBarSize.width, statusBarSize.height);
}
