Question

Answer 1

You can set an Image in UIImage object eiter of the following way:

1. UIImage *imageObject = [UIImage imageNamed:@"imageFileName"]; but by initializing UIImage Object like this, the image is always stored in cache memory even you make it nil like imageObject=nil;

Its better to follow this:

1. NSString *imageFilePath = [[NSBundle mainBundle] pathForResource:@"imageFilename" ofType:@"imageFile_Extension"];

   UIImage *imageObject = [UIImage imageWithContentsOfFile:imageFilePath];
   

EXAMPLE: NSString *imageFilePath = [[NSBundle mainBundle] pathForResource:@"abc" ofType:@"png"];

UIImage *imageObject = [UIImage imageWithContentsOfFile:imageFilePath];
