使用HTML5构建iOS原生APP(5)我的app基本上是由一个原生的navigation controller贯穿全局,然后在每一个scene中都有一个主要的 - (void)viewDidLoad{ ... self.webView = [[UIWebView alloc] initWithFrame:CGRectMake(.0f, 0.f, self.view.bounds.size.width, self.view.bounds.size.height -44)];//-44是减去标题栏高度 self.webView.delegate = self; ... [self.view addSubview:self.webView]; } 现在的问题是,当手机翻转的时候,webView的大小不会重绘,就会出现bug,解决办法很简单,就是实现翻转委托: - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation { NSLog(@"I have finished rotating"); self.webView.frame = CGRectMake(.0f, 0.f, self.view.bounds.size.width, self.view.bounds.size.height)); } 就可以了,然后在webView中做好宽度自适应: <meta name="viewport" content="width=device-width, initial-scale=1.0, user-scable=0, minimun-scale=1.0, maximum-scale=1.0"> 备注介绍一下view的三种坐标属性: Frame A view’s frame (CGRect) is the position of its rectangle in the superview’s coordinate system. By default it starts at the top left. Bounds A view’s bounds (CGRect) expresses a view rectangle in its own coordinate system. Center A center is a CGPoint expressed in terms of the superview’s coordinate system and it determines the position of the exact center point of the view. 本文出自:http:///, 原文地址:http:///wr?u=http%3A%2F%2F%2Fweblog%2Fiphone-rotation-webview%2F, 感谢原作者分享。 |
