My dictionary content is <NSString*, UIImage*>

How to retrieve the values of my dictionary.

Code Snippet:

for (int i=0 ; i< [imagesToFill count]; i++) {

    NSDictionary* dict = [imagesToFill objectAtIndex:i];

    UIImage*  img =   ??? [dict]  // How to retrive value from above dict which has only 1 entry
    NSString* imgPath =  ??? 

}


 Note: Each dict has <NSString*, UIImage*>

Answer 1

you can get all keys of a dictionary like that:

NSArray *allKeys = [dictionary allKeys];

and of course the same is true for all values:

NSArray *allValues = [dictionary allValues];

And then simply use objectAtIndex:0 (or lastObject) to access your key or value.

The order of both arrays is not defined (i.e. random). This won’t be a problem in your case. But keep that in mind.
