ios - iOS7 键盘返回/完成/搜索色调颜色

Question

使用新的 iOS7 UIView 色调颜色，可以很容易地快速为整个应用程序设置主题。它甚至在编辑 UITextField 时更改文本插入符号的颜色。

但是，键盘右下角的“关闭”按钮（可以是完成、搜索等）始终为蓝色。有什么办法可以改变这个吗？如果它与应用程序其余部分的色调相匹配，它看起来会非常好。

通过一点技巧，也许你可以达到你想要的效果。但它可能无法通过应用审查。

-(NSArray*)subviewsOfView:(UIView*)view withType:(NSString*)type{
    NSString *prefix = [NSString stringWithFormat:@"<%@",type];
    NSMutableArray *subviewArray = [NSMutableArray array];
    for (UIView *subview in view.subviews) {
        NSArray *tempArray = [self subviewsOfView:subview withType:type];
        for (UIView *view in tempArray) {
            [subviewArray addObject:view];
        }
    }
    if ([[view description]hasPrefix:prefix]) {
        [subviewArray addObject:view];
    }
    return [NSArray arrayWithArray:subviewArray];
}

-(void)addColorToUIKeyboardButton{
    for (UIWindow *keyboardWindow in [[UIApplication sharedApplication] windows]) {
        for (UIView *keyboard in [keyboardWindow subviews]) {
            for (UIView *view in [self subviewsOfView:keyboard withType:@"UIKBKeyplaneView"]) {
                UIView *newView = [[UIView alloc] initWithFrame:[(UIView *)[[self subviewsOfView:keyboard withType:@"UIKBKeyView"] lastObject] frame]];
                newView.frame = CGRectMake(newView.frame.origin.x + 2, newView.frame.origin.y + 1, newView.frame.size.width - 4, newView.frame.size.height -3);
                [newView setBackgroundColor:[UIColor greenColor]];
                newView.layer.cornerRadius = 4;
                [view insertSubview:newView belowSubview:((UIView *)[[self subviewsOfView:keyboard withType:@"UIKBKeyView"] lastObject])];

            }
        }
    }
}

您不能更改按钮色调颜色，但您可以keyboard使用设置色调颜色 UIKeyboardAppearance

示例：yourTextField.keyboardAppearance = UIKeyboardAppearanceDark;

这是Apple提供的一个非常好的文档，请看这里：

Answer 3

let colors: [UIColor] = [.red, .blue, .green, .purple, .yellow, .orange, .brown]

if let window = UIApplication.shared.windows.first(where: { 
    $0.isType(string: "UIRemoteKeyboardWindow") 
}) {
    if let keyplaneView = window.subview(ofType: "UIKBKeyplaneView") {
        for (i, keyView) in keyplaneView.subviews.filter({
            $0.isType(string: "UIKBKeyView") 
        }).enumerated() {
            let view = UIView(frame: keyView.bounds)
            view.backgroundColor = colors[i].withAlphaComponent(0.5)
            keyView.addSubview(view)
        }
    }
}

这是 中键的颜色映射UIKBKeyplaneView：
