[英]Navigation bar Title not set and back button not disable in UITableViewControler
我在情節提要中使用UITableViewController。
[self.navigationController setNavigationBarHidden:NO animated:NO];
[self.navigationItem setHidesBackButton:YES animated:YES];
UIBarButtonItem *editButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"back2.png"] style:UIBarButtonItemStylePlain target:self action:@selector(back:)];
self.navigationItem.leftBarButtonItem = editButton;
[self.navigationController.navigationBar setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}];
[self.navigationController.navigationBar setBarTintColor:[UIColor colorWithRed:(44/255.0f) green:(165/255.0f) blue:(264/255.0f) alpha:(1.0f)]];
[self.navigationItem setTitle:@"SETTINGS"];
self.navigationController.navigationBar.tintColor = [UIColor whiteColor];
問題是我想隱藏“后退”按鈕,標題不顯示在導航欄中。 相同的代碼可在UIViewcontroller中使用。
我使用情節提要板創建了簡單的場景:uinavigation控制器-> uiviewcontroller-> uitableviewController。
代碼可在uiviewcontroller和uitableviewController上運行。
因此,我建議您檢查以下內容:
至於標題和欄裝飾,我將這兩種方法用作UIViewController的類別,以將裝飾邏輯與標題邏輯分開
-(void)decorateNavigationBarAppearance
{
[self.navigationController.navigationBar setBackgroundImage:[UIImage new]
forBarMetrics:UIBarMetricsDefault];
self.navigationController.navigationBar.shadowImage = [UIImage new];
self.navigationController.navigationBar.translucent = YES;
self.navigationController.view.backgroundColor = [UIColor clearColor];
self.navigationController.navigationBar.backgroundColor = [UIColor clearColor];
self.navigationController.navigationBar.tintColor = RGB(255, 255, 255);
self.navigationController.navigationBar.shadowImage = [self imageWithColor:RGB(154, 153, 163) size:(CGSizeMake(self.view.frame.size.width, 1.0f))];
}
- (void) setNavigationItemTitle:(NSString *)title
{
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 0, 310, 40)];
titleLabel.text = title;
titleLabel.textAlignment = NSTextAlignmentLeft;
titleLabel.font = [UIFont fontWithName:@"ProximaNova-Bold" size:17];
titleLabel.backgroundColor = [UIColor clearColor];
titleLabel.textColor = RGB(255, 255, 255);
UIView *content = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 40)];
[content addSubview:titleLabel];
self.navigationItem.titleView = content;
}
當然,您可以僅出於修改裝飾參數(例如顏色或字體名稱/大小)的目的使用此代碼段
希望這可以幫助。
