iphone - 将图像添加到iPhone中工具栏的栏按钮项

Question

我想将图像添加到工具栏的栏按钮项我尝试使用 xib 并编码两者但图像显示为白色补丁有人能建议我做错了什么吗或者我应该采取哪种方式进行

Answer 1

将按钮类型设置为自定义。

尝试这样

UIButton *button =  [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:[UIImage imageNamed:@"myImage.png"] forState:UIControlStateNormal];
[button addTarget:self action:@selector(blah) forControlEvents:UIControlEventTouchUpInside];
[button setFrame:CGRectMake(0, 0, 32, 32)];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];

祝一切顺利。
