macOS 开发 报 Failed to set (contentViewController) user defined inspected property on (NSWindow): -...

viewcontroller 初始化不同

IOS alloc init 会自动创建空view

mac alloc init不会主动创建，需重写-(void)loadview方法，否则会报nib找不到的错误：

Failed to set (contentViewController) user defined inspected property on (NSWindow): -[NSNib _initWithNibNamed:bundle:options:] could not load the nibName: HWVC1 in bundle (null).

解决：需重写-(void)loadview方法

-(void)loadView

{

NSRect frame=[[[NSApplication sharedApplication]mainWindow]frame];

self.view=[[NSView alloc]initWithFrame:frame];

}
