objective c - How to set image to UIImage

Question

How can I set image to UIImage object. For example:

UIImage *img = [[UIImage alloc] init];
[img setImage:[UIImage imageNamed:@"anyImageName"]];

My UIImage object is declared in .h file and allocated in init method, I need to set image in viewDidLoad method. Any ideas?

Answer 1

UIImage *img = [UIImage imageNamed:@"anyImageName"];

imageNamed:
Returns the image object associated with the specified filename.

    + (UIImage *)imageNamed:(NSString *)name

Parameters
name
The name of the file. If this is the first time the image is being loaded, the method looks for an image with the specified name in the application’s main bundle.
Return Value
The image object for the specified file, or nil if the method could not find the specified image.

Discussion
This method looks in the system caches for an image object with the specified name and returns that object if it exists. If a matching image object is not already in the cache, this method loads the image data from the specified file, caches it, and then returns the resulting object.
