first run issue

[nivbp7]

Hi, I'm trying to use the code, but can't seem to get it to run.

This is the code:

`

import "ViewController.h"

import "JPSVolumeButtonHandler.h"

@interface ViewController ()

@property (nonatomic,strong) JPSVolumeButtonHandler *volumeButtonHandler;

@end

@implementation ViewController

• (void)viewDidLoad { [super viewDidLoad]; }

-(void)viewWillAppear:(BOOL)animated{ [super viewWillAppear:animated]; [self.volumeButtonHandler stopHandler]; [self.volumeButtonHandler startHandler:YES]; [NSTimer scheduledTimerWithTimeInterval:2.0 target:self selector:@selector(takePhoto) userInfo:nil repeats:NO];

}

-(void)takePhoto{ NSLog(@"takePhoto"); self.volumeButtonHandler = [JPSVolumeButtonHandler volumeButtonHandlerWithUpBlock:^{ // Volume Up Button Pressed NSLog(@"Volume Up Button Pressed");

} downBlock:^{
    // Volume Down Button Pressed
    NSLog(@"Volume Down Button Pressed");

}];

} @end `
