在应用中调用另一个类

Question

如何在ViewController viewDidLoad片段代码中调用journalView页面？我还在journalView类中创建了journalView.xib。

- (void)viewDidLoad {
    [super viewDidLoad];
    self.version.text = [NSString stringWithFormat:@"UAirship Version: %@", [UAirshipVersion get]];
    [UAPush useCustomUI:[UAPushUI class]];

}
