    [self getImagewithIndex:0];
}

/*
#pragma mark - Navigation

// In a storyboard-based application, you will often want to do a little preparation before navigation

    // Get the new view controller using [segue destinationViewController].
    // Pass the selected object to the new view controller.
}
*/



- (IBAction)pre:(id)sender {
    self.index--;
    [self getImagewithIndex:self.index];
}
- (IBAction)next:(id)sender {
    self.index++;
    [self getImagewithIndex:self.index];
    
  
}

-(void) getImagewithIndex:(int)index{
    NSDictionary *dictionary=self.picArr[index];
    self.lblTitle.text=[NSString stringWithFormat:@"%d/%d",index+1,_picArr.count];
    self.lblDescrible.text=dictionary[@"title"];
    self.img.image=[UIImage imageNamed:dictionary[@"icon"]];
    self.btnPre.enabled=(index!=0);
    self.btnNext.enabled=(index!=(self.picArr.count-1));

}
