Can anyone tell me how to use the UIImagePickerController (camera and album) delegates determine the image's orientation, rotate accordingly, and assign it to a UIImageView? No, UIImagePickerController cannot do it explicitly. If you want to determine based on image's content. It is kind of hard problem. How can you determine an image's orientation without understanding the content inside of it? I can suggest you a trick that you examine the width and the length of the returned image and see if it is portrait or landscape. For rotating the image, there are some libraries and codes outside but

After user choose image from the iPhone library with UIImagePickerController , I want to upload it to my server using ASIHTTPRequest library. I know that with ASIHTTPRequest I can upload a file with the file's URl, but how do I get the image URL? I know I can get the image UIImagePickerControllerReferenceURL , that look like this: "assets-library://asset/asset.JPG?id=F2829B2E-6C6B-4569-932E-7DB03FBF7763&ext=JPG" is this the URL I need to use? There are two ways 1: You can upload the image using the imagePickerController delegate - (void)imagePickerController:(UIImagePickerController *)picker

How can I let a user select a photo from the Apple Photos library? How do we show the system camera UI to allow the user to take a picture? EDIT: March 15, 2016 - Here is a swift version of my prior answer, if you're looking for the objective-c version you'll find it below. -- SWIFT -- First conform to the UIImagePickerControllerDelegate protocol and the UINavigationControllerDelegate protocol class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate launch the image picker func actionLaunchCamera() { if UIImagePickerController

UIImageWriteToSavedPhotosAlbum is only working sometimes. Sometimes it works, sometimes it doesn't, exact same function. - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo { NSLog(@"Saving image to camera roll..."); UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil); NSLog(@"Done!"); } I am using a UIImagePicker controller to get the image that then calls that function. Sometimes it saves it to the camera roll, other times it simply doesn't. Anyone has any idea? Thanks in advance. Edit: The completion

I have divergent needs for the image returned from the iPhone camera. My app scales the image down for upload and display and, recently, I added the ability to save the image to the Photos app. At first I was assigning the returned value to two separate variables, but it turned out that they were sharing the same object, so I was getting two scaled-down images instead of having one at full scale. After figuring out that you can't do UIImage *copyImage = [myImage copy]; , I made a copy using imageWithCGImage , per below. Unfortunately, this doesn't work because the copy (here croppedImage )

I've tried setting the Info.plist 'View controller-based status bar appearance' to NO, I've tried calling [[UIApplication sharedApplication] setStatusBarHidden:YES]; I've tried -(BOOL)prefersStatusBarHidden{ return YES; } I've tried launching the picker with [self presentViewController:picker animated:NO completion:^{ [[UIApplication sharedApplication] setStatusBarHidden:YES]; } And still, there is a status bar overlapping the camera controls. It's only there in iOS 7 though. The status bar doesn't show up any where else in the app. I feel like I'm missing an important piece of the puzzle here

I'm getting hundreds of crashes from one of my live apps ever since people started upgrading to iOS 7. Has anyone else seen this problem? Nothing reproduces on my iPad 3 with iOS 7...
