打开"data:xxx" Safari中的URL [英] Opening "data:xxx" URLs in Safari
问题描述
我无法在iOS/Safari中打开数据URL:.
I'm failing to open data URL:s in iOS/Safari.
NSString* stringUrl = @"data:text/html;base64,PGh0bWw+DQo8Ym9keT4NCjxzY3JpcHQgbGFuZ3VhZ2U9IkphdmFTY3JpcHQiPg0KZG9jdW1lbnQubG9jYXRpb249J2h0dHA6Ly93d3cuZ29vZ2xlLmNvbSc7DQo8L3NjcmlwdD4NCjwvYm9keT4NCjwvaHRtbD4=";
NSURL* url = [NSURL URLWithString:stringUrl];
NSLog(@"Got url: %@", url);
const BOOL STATUS = [UIApplication.sharedApplication openURL:url];
NSLog(@"STATUS: %d", STATUS);
应该在iOS设备上打开Safari.结果页面将是:
This is supposed to open Safari on an iOS device. The resulting page would be:
<html>
<body>
<script language="JavaScript">
document.location='http://www.google.com';
</script>
</body>
</html>
但是openURL失败，STATUS返回NO/0.我们该如何解决?
However openURL fails, STATUS returns NO/0. How do we fix this?
推荐答案
您可以使用UIApplication的特殊方法来确定它是否可以打开您的URL
You can use special method of UIApplication to determine if it can open your URL or not
布尔状态= [UIApplication.sharedApplication canOpenURL :url];
BOOL STATUS = [UIApplication.sharedApplication canOpenURL:url];
但是，在文档中没有提到UIApplication是否能够使用数据"方案打开URL:
However, there is no mention in documentation if UIApplication is capable to open URL with "data" scheme:
"UIKit支持许多方案，包括http，https，tel，facetime和mailto方案." -来自UIApplication的文档.
"UIKit supports many schemes, including http, https, tel, facetime, and mailto schemes." - from documentation for UIApplication.
您可以尝试在内部UIWebView浏览器中打开此URL，并查看此UIWebView方法的用法:
You can attempt to open this URL in internal UIWebView browser and see how it goes with this method of UIWebView:
- (void)loadData:(NSData *)data MIMEType:(NSString *)MIMEType textEncodingName:(NSString *)encodingName baseURL:(NSURL *)baseURL;
