为以编程方式绘制的视图设置颜色

问题描述 投票:2回答:2

我正在修正UITextView,使其不在键盘下方显示,而是将其调整为正确的约束。这可能是一个愚蠢的问题,并且很可能在这个愚蠢的问题旁边有一个简单的解决方法,但是我需要将视图(当前为黑色)的颜色涂成whiteColor-看来我在正确的行上空白了这样做的代码。我已经搜索了Stack Overflow和Google一段时间,但没有找到一行不会返回错误的代码。

键盘后面的黑色矩形。“截图”

- (void)keyboardDidShow:(NSNotification *)aNotification {
    NSDictionary* info = [aNotification userInfo];
    CGRect kbRect = [[info objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];
    kbRect = [[self view] convertRect:kbRect fromView:nil];
    CGSize kbSize = kbRect.size;
    CGRect aRect = self.view.frame;

    /* This should work, but doesn't quite qet the job done */
    //    UIEdgeInsets insets = self.textView.contentInset;
    //    insets.bottom = kbSize.height;
    //    self.textView.contentInset = insets;
    //
    //    insets = self.textView.scrollIndicatorInsets;
    //    insets.bottom = kbSize.height;
    //    self.textView.scrollIndicatorInsets = insets;

    /* Instead, we just adjust the frame of the uitextview */
    aRect.size.height -= kbSize.height + VERTICAL_KEYRBOARD_MARGIN;
    self.companyTextField.frame = aRect;

    // If active text field is hidden by keyboard, scroll it so it's visible
    // Your application might not need or want this behavior.
    if (!CGRectContainsPoint(aRect, self.companyTextField.frame.origin) ) {
        CGPoint scrollPoint = CGPointMake(0.0, self.companyTextField.frame.origin.y - kbSize.height);
        [self.companyTextField setContentOffset:scrollPoint animated:YES];
    }
}

假定您正在谈论self.companyTextField

self.companyTextField.backgroundColor = [UIColor whiteColor];

如果您正在谈论主视图:

self.view.backgroundColor = [UIColor whiteColor];

将容器视图的背景色设置为白色。 (主窗口视图),以及scrollview背景颜色为白色。

或者如果后面有其他视图,则将其设置为白色。

编辑:您的代码显示滚动视图,检查其颜色。
