使用XIB自定义一个UIView,然后将这个view添加到controller的view 上(相当于所有界面都通过xib来实现)

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:
