注意：提示错误“loaded the "ViewController" nib but the view outlet was not set.”时，XIB文件中view的Referencing Outlets需连到File’s Owner上。
1. AppDelegate代理中initWithNibName方法
在AppDelegate代理中
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.backgroundColor = [UIColor grayColor];
self.window.rootViewController = [[SelectHeroViewController alloc] initWithNibName:@"SelectHeroViewController" bundle:nil];
即可
2.ViewController中initWithNibName方法
在ViewController中
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
self.view = [[[NSBundle mainBundle] loadNibNamed:@"SelectHero" owner:self options:nil] lastObject];
}
return self;
}
3.Identity inspector中设置
按1，AppDelegate代理中修改第3行
self.window.rootViewController = [[SelectHeroViewController alloc] initWithNibName:@"SelectHeroViewController" bundle:nil];
改为
self.window.rootViewController = [[SelectHeroViewController alloc] init];
然后在xib文件Identity inspector中 选择控制器类
