iOS 4.3 更改了 UIImagePickerController 的相机覆盖视图的转换

iOS 4.3 changed transformation on UIImagePickerController#39;s camera overlay view(iOS 4.3 更改了 UIImagePickerController 的相机覆盖视图的转换)

问题描述

在 iOS 4.3 上测试我的应用后，我注意到我的 UIImagePickerController 的相机叠加层有一个额外的转换，极大地拉伸了内容.在 iOS 4.3 之前，一切都正确显示.

After testing my App on iOS 4.3 I noticed that the camera overlay of my UIImagePickerController has an added transformation that stretched the content extremely. Pre iOS 4.3 everything shows up correctly.

这就是我的工作

imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;

cameraOverlay = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];
cameraOverlay.backgroundColor = [UIColor clearColor];
cameraOverlay.userInteractionEnabled = NO;

//add subviews to camera Overlay

imagePicker.cameraOverlayView = pauseButton;

任何想法我必须做些什么来摆脱添加的转换?

Any ideas what I have to do to get rid of the added transformation?

推荐答案

OK 找到了答案.ios 4.3 要求camerOverlay 与屏幕一样大.所以我的 200x200 相机叠加层被放大了.

OK found the answer. ios 4.3 requires to have the camerOverlay as big as the screen is. So my 200x200 camera overlay was enlarged.

如果我换行:

cameraOverlay = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];

到

cameraOverlay = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];

它有效:).
