我想在前面添加启动画面和前面的acttivity指示器...为此我在Appdelegate.m中添加以下代码
splashView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
splashView.image = [UIImage imageNamed:@"Default.png"];
acivityindicator = [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(67, 24, 30, 30)];
acivityindicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhite;
acivityindicator.autoresizingMask = (UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin);
[window addSubview:splashView];
[window addSubview:acivityindicator];
[window makeKeyAndVisible];
[window bringSubviewToFront:acivityindicator];
[acivityindicator startAnimating];
Run Code Online (Sandbox Code Playgroud)
但只有启动画面正在工作.Activityinicator没有出现.我怎么了
