一、新建一个single view application类型的iOS application工程,名字取为CustomView,如下图,我们不往CustomViewViewController.xib中添加任何控件:
二、新建一个CustomView.xib,过程如下:
然后往界面上拖一个label和一个button:
接下来得建立CustomViewViewController.xib中的view与CustomView.xib的关联了,即将Custom.xib动态加载,然后将该view做为CustomViewViewController的view的subview,放置于正中显示(设置CustomView的中心点为整屏正中央),具体代码如下:
- (void)viewDidLoad { [superviewDidLoad]; // Do any additional setup after loading the view, typically from a nib. NSArray *nib = [[NSBundlemainBundle]loadNibNamed:@"CustomView"owner:selfoptions:nil]; UIView *tmpCustomView = [nibobjectAtIndex:0]; CGRect tmpFrame = [[UIScreenmainScreen] bounds]; [tmpCustomView setCenter:CGPointMake(tmpFrame.size.width / 2, tmpFrame.size.height / 2)]; [self.viewaddSubview:tmpCustomView]; }
运行,最后效果如下所示:
