IOS 自定义导航栏标题和返回按钮标题

IOS中自定义导航栏标题：

UILabel *titleText = [[UILabel alloc] initWithFrame: CGRectMake(160, 0, 120, 50)];

titleText.backgroundColor = [UIColor clearColor];

titleText.textColor=[UIColor whiteColor];

[titleText setFont:[UIFont systemFontOfSize:17.0]];

[titleText setText:@"XXX"];

self.navigationItem.titleView=titleText;

[titleText release];

IOS中自定义导航栏返回按钮：（放在pushViewController之前）

UIBarButtonItem *backItem=[[UIBarButtonItem alloc]init];

backItem.title=@"后退";

backItem.tintColor=[UIColor colorWithRed:129/255.0 green:129/255.0
blue:129/255.0 alpha:1.0];

self.navigationItem.backBarButtonItem = backItem;

[backItem release];

IOS中自定义导航栏右边按钮

UIBarButtonItem * rightButton = [[UIBarButtonItem alloc]

initWithTitle:@"回到首页"
