Question

I have this Alert:

There is no internet connection available, please try again.`

and I have to many code blocks that can produce this message and I want to put the UIAlertView in one class that I would not create it everytime, is that possible?

Answer 1

h file for ActionGeneric class

#import <Foundation/Foundation.h>

@interface ActionGeneric : NSObject {

}

+(void)showAlert;
@end

m file

    #import "ActionGeneric.h"

    @implementation ActionGeneric

     +(void)showAlert{
      UIAlertView *alert = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"haveInternetConnection",@"") 
                                                      message:@"" 
                                                     delegate:nil 
                                            cancelButtonTitle:NSLocalizedString(@"kOk",@"") 
                                            otherButtonTitles:nil];
      [alert show];
      [alert release];
    }
    @end

Then you just import action generic and call it

[ActionGeneric showAllert];
