UITabBarController 的兩種初始化

在deletegate.m裏用代碼生成的TabBarController

其中：

一、viewController = [[ViewController alloc]init];

viewController.m裏

-(id)init{

if((self=[super init])){

self.tabBarItem.image = [UIImage imageNamed:@"news"];

self.tabBarItem.title=@"標題";

}

return self;

}

二、用nib生成的view

如：

self.albumViewController = [[AlbumViewController alloc]initWithNibName:@"AlbumViewController" bundle:nil];

在albumViewController.m裏

-(id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{

self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

if(self){

self.tabBarItem.image = [UIImage imageNamed:"album"];

self.tabBarItem.title = @"相冊";

}

return self;

}
