I’ve been doing some housekeeping on one of the apps I have in the App Store, and I noticed that the image picker was broken when I tested it on the GM version of iOS 8. It took me a while to track it down and, because I couldn’t see the solution on StackOverflow, I thought I’d do a quick posting here.<\/p>\n
So the background to this is if you want to add something into the\u00a0UIImagePickerControllerMediaMetadata dictionary after you have taken a picture, and the classic example is saving back GPS data.<\/p>\n
The long and short of it is that you can no longer assign \u00a0UIImagePickerControllerMediaMetadata straight to a NSMutableDictionary. My code originally looked like this:<\/p>\n
NSMutableDictionary *tmpMetadataDic = [info objectForKey:UIImagePickerControllerMediaMetadata];<\/pre>\nwhich, if I called it, threw an error like this:<\/p>\n
[__NSDictionaryI setObject:forKey:] unrecognized selector sent to instance....<\/code><\/pre>\nThe clue is that reference to NSDictionaryI, which means that you’re trying to set something in a non mutable dictionary.<\/p>\n
So doing something like this works:<\/p>\n
\nNSDictionary\u00a0*nonMutytmpMetadataDic = [info\u00a0objectForKey:UIImagePickerControllerMediaMetadata];\u00a0 \u00a0\u00a0\r\nNSMutableDictionary\u00a0*tmpMetadataDic = [[NSMutableDictionary\u00a0alloc]\u00a0initWithDictionary:nonMutytmpMetadataDic];<\/pre>\n<\/div>\n<\/div>\n<\/p>\n","protected":false},"excerpt":{"rendered":"
