Pass nsstring from a view to uialertview

[bobby456]

Can you help me? I need to pass a Nsstring *urlString that is in viewController to an UIAlertView

Here is what I use :
viewController.m

sAlertView *alert1 = [[sAlertView alloc] initWithTitle:@"Options:" message:nil delegate:self cancelButtonTitle:@"Cancel" okButtonTitle:@"Test"]; 
alert1.tag = 10; 
[alert1 show]; 
[alert1 release];

sAlert.h

#import <UIKit/UIKit.h>
#import <MediaPlayer/MediaPlayer.h>
#import <viewController.h>

@interface sAlertView : UIAlertView {

 UIButton *controlButton;
    MPMoviePlayerController *mMPPlayer;

}
@property (nonatomic, retain)  UIImageView *controlButton;

- (id)initWithTitle:(NSString *)title message:(NSString *)message delegate:(id)delegate cancelButtonTitle:(NSString *)cancelButtonTitle okButtonTitle:(NSString *)okayButtonTitle;


@end

sAlert.m

        #import "sAlertView.h"


        @implementation sAlertView

            - (id)initWithTitle:(NSString *)title message:(NSString *)message delegate:(id)delegate cancelButtonTitle:(NSString
            *)cancelButtonTitle okButtonTitle:(NSString
            *)okayButtonTitle{
                if (self = [super initWithTitle:title message:message delegate:delegate cancelButtonTitle:cancelButtonTitle otherButtonTitles:okayButtonTitle, nil])  {    
                 controlButton = [UIButton buttonWithType:UIButtonTypeCustom];   
[controlButton setImage:[UIImage imageNamed:@"play.png"] forState:UIControlStateNormal];   
controlButton.frame = CGRectMake(125, 45, 35, 30);   
[controlButton addTarget:self action:@selector(buttonPushed) forControlEvents:UIControlEventTouchUpInside];   
[self addSubview:controlButton];

                }  return self; }

      - (void) buttonPushed{  
         mMPPlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:urlString]];  
    [mMPPlayer play];  
     } ...

Declare the NSString as a Global Variable.

Since you're using a custom subview of UIAlertView, add a new NSString property to the alert view and set it when you create the alert. Like this:


viewController.m

sAlertView *alert1 = [[sAlertView alloc] initWithTitle:@"Options:" message:nil delegate:self cancelButtonTitle:@"Cancel" okButtonTitle:@"Test"]; 
alert1.tag = 10; 
alert1.urlString = @"http://somedomain/somepath/somefile";
[alert1 show]; 
[alert1 release];

sAlert.h

#import <UIKit/UIKit.h>
#import <MediaPlayer/MediaPlayer.h>
#import <viewController.h>

@interface sAlertView : UIAlertView {

 UIButton *controlButton;
    MPMoviePlayerController *mMPPlayer;

}
@property (nonatomic, retain)  UIImageView *controlButton;
@property (nonatomic, retain)  NSString *urlString;

- (id)initWithTitle:(NSString *)title message:(NSString *)message delegate:(id)delegate cancelButtonTitle:(NSString *)cancelButtonTitle okButtonTitle:(NSString *)okayButtonTitle;


@end

sAlert.m

        #import "sAlertView.h"


        @implementation sAlertView

        @synthesize urlString;

            - (id)initWithTitle:(NSString *)title message:(NSString *)message delegate:(id)delegate cancelButtonTitle:(NSString
            *)cancelButtonTitle okButtonTitle:(NSString
            *)okayButtonTitle{
                if (self = [super initWithTitle:title message:message delegate:delegate cancelButtonTitle:cancelButtonTitle otherButtonTitles:okayButtonTitle, nil])  {    
                 controlButton = [UIButton buttonWithType:UIButtonTypeCustom];   
[controlButton setImage:[UIImage imageNamed:@"play.png"] forState:UIControlStateNormal];   
controlButton.frame = CGRectMake(125, 45, 35, 30);   
[controlButton addTarget:self action:@selector(buttonPushed) forControlEvents:UIControlEventTouchUpInside];   
[self addSubview:controlButton];

                }  return self; }

      - (void) buttonPushed{  
         mMPPlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:urlString]];  
    [mMPPlayer play];  
     } ...


        - (void) dealloc;
        {
          self.urlString = nil;
          [super dealloc];
        }
