UIButton *playNowButton = [[UIButton alloc] initWithFrame:CGRectMake(
0,
0,
64,
32)];
[playNowButton setBackgroundImage:[UIImage imageNamed:@"imagename.png"] forState:UIControlStateNormal];
[playNowButton addTarget:self action:@selector(doSomething)forControlEvents:UIControlEventTouchDown];
UIBarButtonItem *bar =
[[UIBarButtonItem alloc] initWithCustomView:playNowButton];
[playNowButton release];
思路 创建一个UIButton将创建的UIButton作为UIBarButtonItem的参数传给UIBarButtonItem的初始化消息initWithCustomView中。
