Ios 未显示自定义视图
我正在为我的项目使用Ios 未显示自定义视图,ios,objective-c,Ios,Objective C,我正在为我的项目使用MVC模型技术。如果我在viewdiload中直接在viewController文件中为custom view编写代码，则会出现view。但若我正在为视图创建另一个类，那个么它并没有显示标签 代码： -(UIView*)homeView:(UIView*)Hview { toplabel=[[UILabel alloc]initWithFrame:CGRectMake(0, 18, Hview.frame.size.width,30)]; toplabel
MVCviewdiloadviewControllercustom viewview-(UIView*)homeView:(UIView*)Hview
{
toplabel=[[UILabel alloc]initWithFrame:CGRectMake(0, 18, Hview.frame.size.width,30)];
toplabel.text=@"NexgHomes.com";
toplabel.textColor=[UIColor whiteColor];
toplabel.textAlignment=NSTextAlignmentCenter;
toplabel.font=[UIFont fontWithName:@"Helvetica"size:18];
toplabel.backgroundColor=[UIColor blueColor];
[Hview addSubview:toplabel];
return Hview;
}
- (void)viewDidLoad{
[homepagVar homeView:self.view]; /* homepagVar is the variable of homePage class and homeView is method of homePage class */
[super viewDidLoad];
}
-(UIView*)homeView:(UIView*)Hview
{
toplabel=[[UILabel alloc]initWithFrame:CGRectMake(0, 18, Hview.frame.size.width,30)];
toplabel.text=@"NexgHomes.com";
toplabel.textColor=[UIColor whiteColor];
toplabel.textAlignment=NSTextAlignmentCenter;
toplabel.font=[UIFont fontWithName:@"Helvetica"size:18];
toplabel.backgroundColor=[UIColor blueColor];
[Hview addSubview:toplabel];
return Hview;
}
- (void)viewDidLoad{
[super viewDidLoad];
[homepagVar homeView:self.view];
[self.view addSubview:homepagVar];
}
您必须在viewDidLoad中添加子视图，因为不同的类可能有不同的self.view实例。我首先猜测是标签被剪裁，因为它不适合矩形。嗯，在homeView方法中，您应该用Hview替换self.view。您不应该将子视图添加到
