添加有背景图片的按钮

Question

按钮实现有背景图片，没有title，在点击时有相应，将按钮添加到导航条中，导航条如下：

-(void)viewDidLoad{
[super viewDidLoad];
    [self.navigationBar setFrame:CGRectMake(0,0,320,50)];
    self.navigationBar.tintColor=[UIColor whiteColor];
}

现在显示出白色的导航条，接下来怎么添加带图片的按钮？
谢谢

Answer 1

-(void)viewDidLoad{
[super viewDidLoad];
    [self.navigationBar setFrame:CGRectMake(0,0,320,50)];
    self.navigationBar.tintColor=[UIColor whiteColor];

   UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"yourImageName"]
                         style:UIBarButtonItemStyleBordered
                        target:self action:@selector(yourButtonPressMethodName:)];   
    self.navigationItem.leftBarButtonItem = item;//use rightBarButtonItem if you want to add button on right dife
}
