将 YouTube 视频嵌入到 [英] Embedding YouTube videos on
问题描述
我通过在互联网上找到的片段嵌入了来自 YouTube 的视频，这是我使用的代码:
I've embedded a video from YouTube via a snippet I've found on the Internet, here is the code that I've used:
@interface FirstViewController (Private)
- (void)embedYouTube:(NSString *)urlString frame:(CGRect)frame;
@end
@implementation FirstViewController
- (void)viewDidLoad {
[super viewDidLoad];
[self embedYouTube:@"http://www.youtube.com/watch?v=l3Iwh5hqbyE" frame:CGRectMake(20, 20, 100, 100)];
}
- (void)embedYouTube:(NSString *)urlString frame:(CGRect)frame {
NSString *embedHTML = @"
<html><head>
<style type="text/css">
body {
background-color: transparent;
color: white;
}
</style>
</head><body style="margin:0">
<embed id="yt" src="%@" type="application/x-shockwave-flash"
width="%0.0f" height="%0.0f"></embed>
</body></html>";
NSString *html = [NSString stringWithFormat:embedHTML, urlString, frame.size.width, frame.size.height];
UIWebView *videoView = [[UIWebView alloc] initWithFrame:frame];
[videoView loadHTMLString:html baseURL:nil];
[self.view addSubview:videoView];
[videoView release];
}
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
- (void)viewDidUnload {
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc {
[super dealloc];
}
@end
它编译正确，当我打开它时，我看到一个白框位置不正确，这是代码创建的.我有两个问题:
It compiles correctly and when I open it, I see a white box positioned incorrectly, which the code created. I have two questions regarding it:
我怎么知道视频是否可以播放，它只是一个普通的白色框，模拟器是否可以播放来自 YouTube 的视频?
How do I know if the video will play, it is just a plain white box, does the simulator play videos from YouTube?
如何定位这个框?
推荐答案
刚刚测试了你的代码，它在 iPhone 上运行良好，但 iOS 模拟器不支持 Youtube 视频，所以你需要一个真实的设备进行测试.
Just tested your code, it works fine on an iPhone, Youtube videos are not supported on the iOS simulator though, so you'll need a real device for testing.
如何定位这个框?
您已经在这一行传递了盒子的 X (20)、Y(20)、宽度(100) 和高度(100):
You are already passing the X (20), Y(20), width(100) and height(100) of the box at this line:
[self embedYouTube:@"http://..." frame:CGRectMake(20, 20, 100, 100)];
要在之后更改视图的位置，请修改其 center 属性:
To change the position of the view afterwards, you modify its center property:
videoView.center = CGPointMake(200, 100 );
