UIImagePickerController - 裁剪图片到正方形（在纵向）

问题描述

我使用UIImagePickerController来拍摄和编辑图片。它在景观中工作正常，但在肖像中它会将图片裁剪成一个正方形（不允许减少图像完全适合正方形作物领域像景观一样。任何想法？

代码：

   - （IBAction）initCamera：（id）sender {
 
 // Init imagePicker instance 
 UIImagePickerController * imagePicker = [[UIImagePickerController alloc] init]; 
 [imagePicker setDelegate：self]; 
 
 [imagePicker setSourceType：UIImagePickerControllerSourceTypeCamera]; 
 [imagePicker setShowsCameraControls：YES]; 
 [imagePicker setAllowsEditing：YES]; 
 
 [self presentModalViewController：imagePicker animated：YES]; 
 [imagePicker release]; 
 }检查库，它可以设置您的自定义图像裁剪区域，如下所示：
  self.imagePicker = [[GKImagePicker alloc] init]; 
 self.imagePicker.cropSize = CGSizeMake（320，90）; 
 self.imagePicker.delegate = self; 
 
 [self presentModalViewController：self.imagePicker.imagePickerController animated：YES]; 
  
 
I'm using the UIImagePickerController to take and edit a picture. it works fine in landscape, but in portrait it will crop the picture into a square (does not allow to reduce the image to fit fully into the square crop field like in landscape. Any ideas?
code:
-(IBAction)initCamera:(id)sender{

//Init imagePicker instance
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
[imagePicker setDelegate:self];

[imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
[imagePicker setShowsCameraControls:YES];
[imagePicker setAllowsEditing:YES];

[self presentModalViewController:imagePicker animated:YES];
[imagePicker release];
}
 解决方案 
Check out GKImagePicker library, it allows to set your custom image crop area, like this:
self.imagePicker = [[GKImagePicker alloc] init];
self.imagePicker.cropSize = CGSizeMake(320, 90);
self.imagePicker.delegate = self;

[self presentModalViewController:self.imagePicker.imagePickerController animated:YES];
