UIToolbar setBackgroundColor doesn't fully change color

问题

I'm trying to set the background color of a UIToolBar. I tried selecting the color from IB's Attribute Inspector, and tried setting it programmatically through setBackgroundColor:[UIColor ...].

Both solutions work, but only partially: the color blends something like 50% with white and the toolbar is very light...doesn't show the color I actually chose, but a much lighter version of it.

How can I have the UIToolBar of the actual color I'm choosing? It's probably very simple to solve, but I can't find a way and can't find answers online either.

回答1:

Write below code in your viewDidLoad

self.navigationController.toolbar.barTintColor = [UIColor redColor];

It will set red color as your tool bar background.

In it they said that Use barTintColor to tint the bar background.

IN iOS 7 you need to set the barTintColor Property-

UIToolbar *doneToolbar=[[UIToolbar alloc]initWithFrame:CGRectMake(0, 584, 320, 44)];
doneToolbar.translucent=NO;
doneToolbar.barTintColor=[UIColor redColor];
[self.view addSubview:doneToolbar];

I have used it its working fine...

In addition to Jageen's answer, you must also set the translucent property to false. Otherwise the color will have slightly less saturation and hue than what is specified with barTintColor.

// Sets to a specific color
self.navigationController.toolbar.barTintColor = UIColor colorWithRed:6.0 / 255.0 green:52.0 / 255.0 blue:90.0 / 255.0 alpha:1.0];

// Without this, color will be faded slightly and not exactly what's specified above  
self.navigationController.toolbar.translucent = false;

Try this on IOS 10:

let dummyToolbar = UIToolbar()
dummyToolbar.barTintColor = .lightGray
dummyToolbar.sizeToFit() // without this line it doesn't work

回答5:

UIToolbar* numberToolbar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];

numberToolbar.backgroundcolor = [UIColor redcolor]; numberToolbar.items = [NSArray arrayWithObjects: [[UIBarButtonItem alloc]initWithTitle:@"Clear" style:UIBarButtonItemStyleBordered
nil];

[numberToolbar sizeToFit];
numberTextField.inputAccessoryView = numberToolbar;

回答6:

Throughout App:

    UIToolbar.appearance().barTintColor = TOOLBAR_BACKGROUND_COLOR

if let font = UIFont(name: "AvenirNext-DemiBold", size: 15) {
        UIBarButtonItem.appearance().setTitleTextAttributes([NSFontAttributeName: font,NSForegroundColorAttributeName:TOOLBAR_TITLE_COLOR], forState: UIControlState.Normal)

    }

回答7:

Swift 4+:

toolBar.barTintColor = UIColor(red: 92/255, green: 216/255, blue: 255/255, alpha: 1)
toolBar.isTranslucent = false
toolBar.sizeToFit()
