iOS中打开的文件如何用其他应用打开选择自己的app

释放双眼,带上耳机,听听看~!
效果如图:

用其他应用打开
选择某一应用
1、设置 Info.plist
<key>CFBundleDocumentTypes</key>
<array>
<dict>
<key>CFBundleTypeIconFiles</key>
<array>
<string>96.png</string>
<string>96@2x.png</string>
</array>
<key>CFBundleTypeName</key>
<string>com.myapp.common-data</string>
<key>LSItemContentTypes</key>
<array>
<string>com.microsoft.powerpoint.ppt</string>
<string>public.item</string>
<string>com.microsoft.word.doc</string>
<string>com.adobe.pdf</string>
<string>com.microsoft.excel.xls</string>
<string>public.image</string>
<string>public.content</string>
<string>public.composite-content</string>
<string>public.archive</string>
<string>public.audio</string>
<string>public.movie</string>
<string>public.text</string>
<string>public.data</string>
</array>
</dict>
</array>
2、设置 AppDelegate
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
if (self.window) {
if (url) {
NSString *fileName = url.lastPathComponent; // 从路径中获得完整的文件名(带后缀)
// path 类似这种格式:file:///private/var/mobile/Containers/Data/Application/83643509-E90E-40A6-92EA-47A44B40CBBF/Documents/Inbox/jfkdfj123a.pdf
NSString *path = url.absoluteString; // 完整的url字符串
path = [self URLDecodedString:path]; // 解决url编码问题
NSMutableString *string = [[NSMutableString alloc] initWithString:path];
if ([path hasPrefix:@"file://"]) { // 通过前缀来判断是文件
// 去除前缀:/private/var/mobile/Containers/Data/Application/83643509-E90E-40A6-92EA-47A44B40CBBF/Documents/Inbox/jfkdfj123a.pdf
[string replaceOccurrencesOfString:@"file://" withString:@"" options:NSCaseInsensitiveSearch range:NSMakeRange(0, path.length)];
// 此时获取到文件存储在本地的路径,就可以在自己需要使用的页面使用了
NSDictionary *dict = @{@"fileName":fileName,
@"filePath":string};
[[NSNotificationCenter defaultCenter] postNotificationName:@"FileNotification" object:nil userInfo:dict];
return YES;
}
}
}
return YES;
}
// 当文件名为中文时,解决url编码问题
- (NSString *)URLDecodedString:(NSString *)str {
NSString *decodedString=(__bridge_transfer NSString *)CFURLCreateStringByReplacingPercentEscapesUsingEncoding(NULL, (__bridge CFStringRef)str, CFSTR(""), CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding));
DLog(@"decodedString = %@",decodedString);
return decodedString;
}
3、接收通知
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(fileNotification:) name:@"FileNotification" object:nil];
- (void)fileNotification:(NSNotification *)notifcation {
NSDictionary *info = notifcation.userInfo;
// fileName是文件名称、filePath是文件存储在本地的路径
// jfkdfj123a.pdf
NSString *fileName = [info objectForKey:@"fileName"];
// /private/var/mobile/Containers/Data/Application/83643509-E90E-40A6-92EA-47A44B40CBBF/Documents/Inbox/jfkdfj123a.pdf
NSString *filePath = [info objectForKey:@"filePath"];
NSLog(@"fileName=%@---filePath=%@", fileName, filePath);
