從照片庫分辨率的圖像總是640 * 480

Question

我正在一個模塊，我需要從照片庫中挑選圖像，並在view.draw上繪圖，但每當我選擇大規模圖像它總是會返回我640 * 480縮放圖像和因爲那個小圖像被顯示。

我開啓了AllowEditing。

任何人都可以幫助我找到原始圖像的分辨率，以便我可以再次將其縮放到原始圖像。

iImagePicker.allowsImageEditing = YES; 

- (void)imagePickerController:(UIImagePickerController *)picker 
     didFinishPickingImage:(UIImage *)image 
        editingInfo:(NSDictionary *)editingInfo 
{ 

    [[iImagePicker parentViewController] dismissModalViewControllerAnimated:YES]; 
    iIsImageSaved = YES; 
    iSavedImage = [editingInfo objectForKey:@"UIImagePickerControllerOriginalImage"];; 
    int width,height; 
    width = iSavedImage.size.width; 
    height = iSavedImage.size.height; 

    iApp->ImagePicked(image); 
} 

感謝，

你並不需要擴展你的形象回來，這應該是可用反正。檢查我的答案this question（這是一個重複的，我認爲..）

您使用的是deprecated method [更新了你的代碼的答案]，嘗試imagePickerController:didFinishPickingMediaWithInfo:與UIImagePickerControllerOriginalImage鍵代替。

添加的代碼片段：

-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { 
    UIImage* originalImage = [info objectForKey:UIImagePickerControllerOriginalImage]; 
    NSLog(@"Original image width: %f and height: %f", originalImage.size.width, originalImage.size.height); 

    UIImage* editedImage = [info objectForKey:UIImagePickerControllerEditedImage]; 
    NSLog(@"Edited image width: %f and height: %f", editedImage.size.width, editedImage.size.height); 

    [self dismissModalViewControllerAnimated:YES]; 
}
