iOS 7 status bar and self.view.frame and self.view.bounds
提问by Mrwolfy
I recently released an iOS6 app, and I need to update it for iOS 7. The new status bar is a bit of an issue. The frame/bounds of self.view seem to have changed (+20 points) and I use self.view.bounds to determine the placement of some elements. I have been looking at some solutions. Basically I need to update the app while still supporting the iOS 6 status bar. Is there a best practice for this?
我最近发布了一个 iOS6 应用程序，我需要为 iOS 7 更新它。新的状态栏有点问题。self.view 的框架/边界似乎发生了变化（+20 分），我使用 self.view.bounds 来确定某些元素的位置。我一直在寻找一些解决方案。基本上我需要更新应用程序，同时仍然支持 iOS 6 状态栏。是否有最佳实践？
The code below seems to work to detect an iOS 7 device and shift the content into position, but also causes other issues. Anyway I am not confident that this is the best way.
下面的代码似乎可以检测 iOS 7 设备并将内容移动到位，但也会导致其他问题。无论如何，我不相信这是最好的方法。
if([[[[UIDevice currentDevice] systemVersion] componentsSeparatedByString:@"."][0] intValue] >= 7) {
CGRect statusBarViewRect = [[UIApplication sharedApplication] statusBarFrame];
float heightPadding = statusBarViewRect.size.height+self.navigationController.navigationBar.frame.size.height;
[myContentView setFrame:CGRectMake(0, heightPadding, self.view.frame.size.width, self.view.frame.size.height - heightPadding)];
}

You can achieve this by implementing new property called edgesForExtendedLayout in iOS7 SDK. Please add the following code to achieve this,
您可以通过在 iOS7 SDK 中实现名为 edgeForExtendedLayout 的新属性来实现这一点。请添加以下代码以实现此目的，
if ([self respondsToSelector:@selector(edgesForExtendedLayout)])
self.edgesForExtendedLayout = UIRectEdgeNone;
You need add the above code in your -(void)viewDidLoad method.
您需要在 -(void)viewDidLoad 方法中添加上述代码。

I used this solution to adjust my view in a modal dialog:
我使用此解决方案在模式对话框中调整我的视图：
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
CGRect sbFrame = [[UIApplication sharedApplication] statusBarFrame];
__block CGRect vFrame = self.view.frame;
__block CGFloat diff = sbFrame.size.height + sbFrame.origin.y - vFrame.origin.y;
if (diff > 0.0)
{
[UIView animateWithDuration:UINavigationControllerHideShowBarDuration
delay:0.0
options: UIViewAnimationOptionCurveEaseOut
animations:^{
vFrame.origin.y += diff;
vFrame.size.height -= diff;
self.view.frame = vFrame;
}
completion:^(BOOL finished){
NSLog(@"Done!");
}];
}
}
}
