Question

i create a view based project named myclass.

and i add another UIviewcontroller subclass to it, named as webdata.

In the webdataviewcontroller.m i get image from the webserver.

I need to display this image on imageview in myclassViewController.m from webdataViewController.m

for this my code in webdataViewController.m is

docDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
    imagepath = [NSString stringWithFormat:@"%@/image.png",docDir];
    logopath = [NSString stringWithFormat:@"%@/logo.png",docDir];

myclassViewController *obj = [[myclassViewController alloc]init];
obj.homeimage.image = [UIImage imageWithContentsOfFile:imagepath];

but image is not displayed,i try to print image in console

NSLog(@"image to display %@",obj.homeimage.image);
NSLog(@"image to display %@",[UIImage imageWithContentsOfFile:imagepath]);    

but i get like this

image to display (null)
 image to display <UIImage: 0x6f614b0>

why i get null for obj.homeimage.image,i did n’t get can any one please help me.

Thank u in adavance.

(Let me add comment if question is not understandable)

Answer 1

Are you sure that obj.homeimage is not nil? If it is nil then obj.homeimage.image = … will result to setting image property to nil object, that is “nothing”.
