解决ios手机上传竖拍照片旋转90度问题

由 ぃ、小莉子 提交于 2019-12-26 19:48:40
html5+canvas进行移动端手机照片上传时，发现ios手机上传竖拍照片会逆时针旋转90度，横拍照片无此问题；Android手机没这个问题。 因此解决这个问题的思路是：获取到照片拍摄的方向角，对非横拍的ios照片进行角度旋转修正。 这里主要利用 exif.js 读取照片的拍摄信息。 Exif.js 提供了 JavaScript 读取图像的原始数据的功能扩展，例如：拍照方向、相机设备型号、拍摄时间、ISO 感光度、GPS 地理位置等数据。 EXIF 数据主要来自拍摄的照片，多用于移动端开发，PC 端也会用到，此插件兼容主流浏览器，IE10 以下不支持。 这里主要 用到 Orientation 属性。 Orientation 属性说明如下： 在页面中首先引入 exif.js 主要代码如下： //获取照片的元信息（拍摄方向） function getPhotoOrientation(img) { var orient; EXIF.getData(img, function() { orient = EXIF.getTag(this, "Orientation"); }); return orient; } //获取照片的拍摄方向 var orient = getPhotoOrientation(image); //判断图片拍摄方向是否旋转了90度 if (orient == 6) {

launching a modal view controller to work around the orientation “lock” of tab bar and nav VCs?

由 一世执手 提交于 2019-12-25 18:28:27
问题 I have an iPhone app with a root view controller (VC) of UITabBarController (set to portrait orientation) with several tabs, one of which is a simple UIViewController. In that UIViewController is a single button - "Play Video", which, when clicked opens a modal view of the video (and automatically starts playing the video). The video view is a UIWebView in a UIViewController. I've been trying to get the Web View's VC to change orientation to landscape but have not had any luck. I've looked

How do I code for the landscape orientation in iPhone?

由 拜拜、爱过 提交于 2019-12-25 02:48:06
问题 I understand that I can change what interface orientations are supported, but if I want the landscape view to be entirely different, or somewhat different than the portrait view, how do I code for it? Thank you. 回答1: Just load another view controller when the orientation changes. To make things simple, I often use a hidden navigation controller and push and pop the views I want for any particular orientation. 回答2: Using a dedicated view controller for each orientation is the easiest approach.

由 六月ゝ 毕业季﹏ 提交于 2019-12-25 00:14:31
问题 On the initial view of my app I want the interface to be portrait only but on the view controllers after that it can be any orientation. I tried this code to lock it but it doesn't work and the view can still rotate: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == UIInterfaceOrientationPortrait); } 回答1: The reason that code is not working is most likely because you are running iOS 6. Try this code instead: - (BOOL
