回答https://stackoverflow.com/a/19249775/1502287为我工作，但我必须对其进行一些更改，以使其与相机插件（可能还有其他插件）以及带有“ height = device-高度”（如果未设置高度部分，则在我的情况下，键盘将显示在视图上方，并在此过程中隐藏一些输入）。
每次您打开相机视图并返回到您的应用程序时，都会调用viewWillAppear方法，并且您的视图将缩小20px。
此外，视口的设备高度将额外增加20像素，从而使内容可滚动并且比Web视图高20像素。
这是相机问题的完整解决方案：
在MainViewController.h中：
@interface MainViewController : CDVViewController
@property (atomic) BOOL viewSizeChanged;
@end
在MainViewController.m中：
@implementation MainViewController
@synthesize viewSizeChanged;
[...]
- (id)init
{
self = [super init];
if (self) {
// On init, size has not yet been changed
self.viewSizeChanged = NO;
// Uncomment to override the CDVCommandDelegateImpl used
// _commandDelegate = [[MainCommandDelegate alloc] initWithViewController:self];
// Uncomment to override the CDVCommandQueue used
// _commandQueue = [[MainCommandQueue alloc] initWithViewController:self];
}
return self;
}
[...]
- (void)viewWillAppear:(BOOL)animated
{
// View defaults to full size. If you want to customize the view's size, or its subviews (e.g. webView),
// you can do so here.
// Lower screen 20px on ios 7 if not already done
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7 && !self.viewSizeChanged) {
CGRect viewBounds = [self.webView bounds];
viewBounds.origin.y = 20;
viewBounds.size.height = viewBounds.size.height - 20;
self.webView.frame = viewBounds;
self.viewSizeChanged = YES;
}
[super viewWillAppear:animated];
}
现在针对视口问题，在deviceready事件监听器中，添加以下内容（使用jQuery）：
if (window.device && parseFloat(window.device.version) >= 7) {
$(window).on('orientationchange', function () {
var orientation = parseInt(window.orientation, 10);
// We now the width of the device is 320px for all iphones
// Default height for landscape (remove the 20px statusbar)
var height = 300;
// Default width for portrait
var width = 320;
if (orientation !== -90 && orientation !== 90 ) {
// Portrait height is that of the document minus the 20px of
// the statusbar
height = document.documentElement.clientHeight - 20;
} else {
// This one I found experimenting. It seems the clientHeight
// property is wrongly set (or I misunderstood how it was
// supposed to work).
// Dunno if it's specific to my setup.
width = document.documentElement.clientHeight + 20;
}
document.querySelector('meta[name=viewport]')
.setAttribute('content',
'width=' + width + ',' +
'height=' + height + ',' +
'initial-scale=1.0,maximum-scale=1.0,user-scalable=no');
})
.trigger('orientationchange');
}
这是我用于其他版本的视口：
<meta name="viewport" content="width=device-width,user-scalable=no,initial-scale=1.0,maximum-scale=1.0" />
现在一切正常。
