objective-c - iOS开发 拍照之后出现一个正方形的框?怎么变成矩形的?

Question

Answer 1

It seems that the box cannot be turned into a rectangle using the native method. You can consider using third-party libraries, such as PEPhotoCropEditor

Answer 2

Rewrite an interface

Answer 3

allowsEditing = NO

Answer 4

UIGraphicsBeginImageContext(size);
[image drawInRect:CGRectMake(0, 0, size.width, size.height)];
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
你改变写size就知道了

Answer 5

It is recommended that you use CaptureSession to build your own camera. If you have high customization requirements for the camera interface, iamgePickerController will disappoint you.
