ios 怎么修改相册界面navigationitem显示

Answer 1

ios修改相册界面navigationitem显示是通过uiviewcontroller添加的navigationbar展示的。具体代码如下：
//创建homeButtonView层
UIView *homeButtonView = [[[UIView alloc]initWithFrame:CGRectMake(0, 0, 55, 40)]autorelease];
UIImageView *homeButtonImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 55, 40)];
homeButtonImageView.image = [UIImage imageNamed:@"nav_btn_home_ipad.png"];
UIButton *homeButton = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 55, 40)];
homeButton.backgroundColor = [UIColor clearColor];
[homeButton addTarget:self action:@selector(back:) forControlEvents:UIControlEventTouchUpInside];
[homeButtonView addSubview:homeButtonImageView];
[homeButtonView addSubview:homeButton];
[homeButton release];
[homeButtonImageView release];

//创建home按钮
UIBarButtonItem *homeButtonItem = [[UIBarButtonItem alloc]initWithCustomView:homeButtonView];
self.navigationItem.leftBarButtonItem=homeButtonItem;
[homeButtonItem release];
