iOS 添加导航栏两侧按钮

self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"首页" style:UIBarButtonItemStyleBordered target:self action:@selector(popToRootView)] ;
 
    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"测试" style:UIBarButtonItemStyleBordered target:self action:@selector(test)] ;

//有时需要设置按钮大小才行

- (void)popToRootView{
 
    [self.navigationController popToRootViewControllerAnimated:YES];
 
}
 
- (void) test{
 
NSLog(@"test");
 
}
