#import "ViewController.h"
#import "BSYItem.h"
#import "BSYView.h"
@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.title = @"首页";
    [self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"bar"] forBarMetrics:UIBarMetricsDefault];
    self.navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObject:[UIColor yellowColor] forKey:NSForegroundColorAttributeName];

    // 左侧按钮
    self.left = [[BSYItem alloc]init];
    self.navigationItem.leftBarButtonItem = [self.left addLeft];
    self.left.left.selected = NO;
    [self.left .left addTarget:self action:@selector(leftclick:) forControlEvents:UIControlEventTouchUpInside];
}
-(void)leftclick:(UIButton *)button

{
    self.left.left.selected =! button.selected;

        if (self.left.left.selected==YES) {
            [UIView beginAnimations:nil context:nil];
            [UIView setAnimationDuration:0.5];
            [UIView setAnimationsEnabled:YES];
            self.slide.frame = CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width/4, [UIScreen mainScreen].bounds.size.height);
            [UIView commitAnimations];
            }else{
                [UIView beginAnimations:nil context:nil];
                [UIView setAnimationDuration:0.5];
                [UIView setAnimationsEnabled:YES];
                self.slide.frame = CGRectMake(0, 0, 0, [UIScreen mainScreen].bounds.size.height);
                [UIView commitAnimations];
        }
    [self addbuttonClick];
}
