//Method Contruction and Call
//1. Define the method in the .h file of the class 
@interface UDAUtilities : NSObject
+(void)trackScreenName:(NSString *)screenName;
@end
	
//2. Define it in the .m file of the class
+ (void)trackScreenName:(NSString *)screenName {
    NSString *eventName = [NSString stringWithFormat:@"%@:PageView:%@", [self deviceIdiomString], screenName];
    NSLog(@"%@", eventName);
	
//3. Later in the code... Called elsewhere
	// Class that intends to use a method of another class must use import statement in the *.h
// If passing in a named property, it must also be defined in the header class 

//*.h
  #import "UDAUtilities.h"  
  […]
  @property (nonatomic, strong) NSString *screenName;  

// *.m
  If (self.screenName) {
  	[UDAUtilities trackScreenName: self.screenName];
  	}
