the image is not retrieving from document directory

Question

i have image in document directory with name 1.png. and i want to display that image in imageview. i used the code below but the image is not displaying in imageview.

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,     NSUserDomainMask, YES);
NSLog(@"%@",paths);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *getImagePath = [documentsDirectory stringByAppendingPathComponent:@"1.png"];
UIImage *img = [UIImage imageWithContentsOfFile:getImagePath];
NSLog(@"%@",getImagePath);
imge.image=img;

Answer 1

1 - What is the result of paths, documentsDirectory and getImagePath is correct or not.

2 - Try set the img filename manually (ie : @"1.png") and check if img is loaded correctly

3 - At the other hand, check the file if it exists in documentsDirectory path (also included by project)

NSURL *url = [NSURL fileURLWithPath:path];

Check if file is exists in your documents directory or not

if([[NSFileManager defaultManager] fileExistsAtPath:path])
NSURL *url = [NSURL fileURLWithPath:path];

Also check in your documents directory if the image is getting saved or not. You are given the name of the image like this

image = [UIImage imageNamed:@"1.png"];

so if you are repeating this line your images will be overwritten in documents directory.

You can also put a check here

BOOL success = [data writeToFile:path atomically:YES];

  if(success)
  NSLog(@"successfully");
  else
  NSLog(@"failed");
