如何在向下滑动UIWebView以修复iOS7状态栏覆盖问题后更改UIWebView背景颜色? [英] How can I change the UIWebView background color after sliding down UIWebView to fix the iOS7 status bar overlay issue?
问题描述
我在写一个Phonegap 3.0+应用程序。
iOS7中的状态栏重叠显示有一个问题,用户
UIWebView背景设置为清除颜色,但不透明
下面是我尝试过的代码到目前为止:
- (void)viewWillAppear:(BOOL)animated {
// ios 7
if([[[UIDevice currentDevice] systemVersion] floatValue]> = 7){
CGRect viewBounds = [self.webView bounds];
viewBounds.origin.y = 20;
viewBounds.size.height = viewBounds.size.height - 20;
self.webView.frame = viewBounds;
[self.webView setOpaque:YES];
//取消注释时,这两个都不起作用:
// [self.webView setBackgroundColor:[UIColor grayColor]];
// self.webView.backgroundColor = [UIColor grayColor];
}
[super viewWillAppear:animated];
}
< hr>
UPDATE 1
- (void) viewWillAppear:(BOOL)animated
{
// ios 7上的下屏幕20px
if([[[UIDevice currentDevice] systemVersion] floatValue]> = 7){
CGRect viewBounds = [self.webView bounds];
viewBounds.origin.y = 20;
viewBounds.size.height = viewBounds.size.height - 20;
self.webView.frame = viewBounds;
self.webView.backgroundColor = [UIColor grayColor];
self.webView.opaque = NO;
}
[super viewWillAppear:animated];
}
这似乎还给我一个白色背景的状态栏,灰色。
我希望的结果是这样的:
所以我意识到代码推动UIWebView下降20px。意思是根据定义的空格不能是UIWebView。白色空间是主视图,我通过执行以下操作来更改背景颜色:
1。转到MainViewController.xib:
< br>
2。选择主视图:
3。显示属性检查器并更改颜色。已完成。
显然现在我想想,但希望这有助于未来的人。

There is an issue with the status bar overlapping views in iOS7 which user Ludwig Kristoffersson provided a working answer here
Now that I have UIWebView with a 20px top margin, how can I change the UIWebView background color? I need the area behind the status bar to be the same background color as the "people" toolbar.
I have almost no experience in Objective C, and have been looking through possible SO questions to find a working solution but with no success.
UIWebView background color
UIWebView background is set to Clear Color, but it is not transparent
Below is the code that I've tried so far:
- (void)viewWillAppear:(BOOL)animated {
//Lower screen 20px on ios 7
if([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
CGRect viewBounds = [self.webView bounds];
viewBounds.origin.y = 20;
viewBounds.size.height = viewBounds.size.height - 20;
self.webView.frame = viewBounds;
[self.webView setOpaque:YES];
//neither of these seem to work when uncommented:
// [self.webView setBackgroundColor:[UIColor grayColor]];
// self.webView.backgroundColor=[UIColor grayColor];
}
[super viewWillAppear:animated];
}
UPDATE 1
- (void)viewWillAppear:(BOOL)animated
{
//Lower screen 20px on ios 7
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
CGRect viewBounds = [self.webView bounds];
viewBounds.origin.y = 20;
viewBounds.size.height = viewBounds.size.height - 20;
self.webView.frame = viewBounds;
self.webView.backgroundColor = [UIColor grayColor];
self.webView.opaque=NO;
}
[super viewWillAppear:animated];
}
That still seems to give me a white background behind the status bar, rather than gray.
The result I'm hoping for is like this:
So I realized that the code pushes the UIWebView down 20px. Meaning that the white space by definition cannot be UIWebView. The white space is the main view which I changed the background color by doing the following:
1. Go to MainViewController.xib:
2. Select the main view:
3. Show the attributes inspector and change the color. Done.
Obvious now that I think about it, but hopefully this helps someone in future.
