#import "iPhone_buttonFunViewController.h"

@implementation iPhone_buttonFunViewController
@synthesize statusText;

-(IBAction)buttonPressed:(id) sender {
    NSString *title;
    NSString *newText;

    title = [sender titleForState:UIControlStateNormal];
    newText = [[NSString alloc] initWithFormat:@"%@ button …
