HI:
I have a point to an object but some API's need only object. How can I convert pointer to an object.

NSString* ImageName = "BigBang.png";
I have a pointer to a string (Image file name) , but [UIImage imageNamed:FileName];


How I can make it work?

You're wrong: the UIImage method takes NSString*. The following declaration is copied verbatim from the UIImage class reference web page:
+ (UIImage *)imageNamed:(NSString *)name



I recommend that you work through an Objective-C tutorial. Then pick one of Apple's iPhone sample apps and work your way through that, so you can understand everything it does. If you don't have a good understanding of the fundamentals, it's not going to work.


You can find examples and class references by searching ADC:

  http://developer.apple.com/search/search.html

For example, to find the method declaration I pasted above, I simple entered these keywords:

  UIImage imageNamed
