[英]TVOutManager working on Simulator, but not on a device?
I am trying to project my iPhone app on an external display.我正在尝试将我的 iPhone 应用程序投影到外部显示器上。 I tried TVOutManager, It works perfect on the simulator (I turned on the TV Out Option, and have tested iOS from 4.0 to 4.3).我尝试了 TVOutManager,它在模拟器上完美运行(我打开了 TV Out 选项,并测试了从 4.0 到 4.3 的 iOS)。 However, when I install the app on my iPhone4, it doesn't work neither on an external display nor on a TV.但是,当我在我的 iPhone4 上安装该应用程序时,它既不能在外部显示器上运行,也不能在电视上运行。 Am I missing something or there are some special requirements for the cable or accessory?我是否遗漏了什么或者对电缆或配件有一些特殊要求?
#import "TVOutManager.h"
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[[TVOutManager sharedInstance] startTVOut];
.....
}
- (void)applicationDidBecomeActive:(UIApplication *)application {
[[TVOutManager sharedInstance] startTVOut];
}
Thanks谢谢
Make sure to use a high quality VGA-cable, or a short one.确保使用高质量的 VGA 电缆或较短的电缆。 Short one is better of course.短的当然更好。
