Good day, I am trying to implement the UIImagePickerController inside my selectFile function. (followed this tutorial in appcoda ) but code below is a bit tweaked now based on what i want
@implementation FileBrowser
-(void)selectFile{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = NO;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker animated:YES completion:NULL];
}
#pragma mark - Image Picker Controller delegate methods
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSURL *refURL = [info valueForKey:UIImagePickerControllerReferenceURL];
NSString *myURL = [refURL absoluteString]; //not in tutorial, I'm trying to grab the url/path of the image here, with an intention of returning it to "callFileBrowser"
[picker dismissViewControllerAnimated:YES completion:NULL];
}
@end
Based on what i understood, my imagePickerController function is called when user selects an image. My question is how do i return(or get) the url instead? I have a C function on the same file (but outside @implemetation), this function calls my selectFile and is supposed to return the url/path of what the user has chosen.
char* callFileBrowser(){
[fileBrowser selectFile];
//return myURL here;
}
I hope i was able to explain everything properly. Any advice would greatly be appreciated. thanks.
I don't think it is possible with the current design. callFileBrowser() is called to pick a image, then immediately it is required to return a value. We don't know when user will be done picking, I suggest you to post a notification in didFinishPickingMediaWithInfo when the url is ready to notify other object who needs it.
