容器程序獲取分享數(shù)據(jù)
插件的工作基本上已經(jīng)全部開發(fā)完成了，接下來就是容器程序獲取數(shù)據(jù)并進(jìn)行操作。下面是容器程序的處理代碼：
- (void)applicationDidBecomeActive:(UIApplication *)application
{ //獲取共享的UserDefaults
NSUserDefaults *userDefaults = [[NSUserDefaults alloc] initWithSuiteName:@"group.cn.vimfung.ShareExtensionDemo"]; if ([userDefaults boolForKey:@"has-new-share"])
{
NSLog(@"新的分享 : %@", [userDefaults valueForKey:@"share-url"]); //重置分享標(biāo)識
[userDefaults setBool:NO forKey:@"has-new-share"];
}
}
為了方便演示，這里直接在AppDelegate中的applicationDidBecomeActive:方法中檢測是否有新的分享，如果有則通過Log打印鏈接出來。
至此，整個(gè)Share Extension開發(fā)的過程已經(jīng)完成。
提審AppStore的注意事項(xiàng)
- 擴(kuò)展中的處理不能太長時(shí)間阻塞主線程（建議放入線程中處處理），否則可能導(dǎo)致蘋果拒絕你的應(yīng)用。
- 擴(kuò)展不能單獨(dú)提審，必須要跟容器程序一起提交AppStore進(jìn)行審核。
- 提審的擴(kuò)展和容器程序的Build Version要保持一致，否則在上傳審核包的時(shí)候會(huì)提示警告，導(dǎo)致程序無法正常提審。（Info.plist : 里面的版本號必須要和主工程的版本號一致，否則審核可能被拒。）
PS:如果想讓Share Extension跳轉(zhuǎn)、打開宿主APP
其實(shí)蘋果官方除了Today Extension外，其他Extension是不提供跳轉(zhuǎn)接口的。所以這里總結(jié)的是兩種非正常的方式。
- 如果只需要在點(diǎn)擊分享框的時(shí)候處理：
- (void)didSelectPost {
// This is called after the user selects Post. Do the upload of contentText and/or NSExtensionContext attachments.
// Inform the host that we're done, so it un-blocks its UI. Note: Alternatively you could call super's -didSelectPost, which will similarly complete the extension context.
NSString *str = [NSString stringWithFormat:@"%@%@", @"comcihaicihaiyun://jump/Search?searchStr=", self.contentText];
[self goConnationWithUrlSTr:[str stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]]];
[self.extensionContext completeRequestReturningItems:@[] completionHandler:nil];
}
- 如果需要在控制器內(nèi)處理，需要在自定義的控制器內(nèi)：
- (void)viewDidLoad
{
[super viewDidLoad];
//獲取分享內(nèi)容
__block BOOL hasGetUrl = NO;
[self.extensionContext.inputItems enumerateObjectsUsingBlock:^(NSExtensionItem * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
[obj.attachments enumerateObjectsUsingBlock:^(NSItemProvider * _Nonnull itemProvider, NSUInteger idx, BOOL * _Nonnull stop) {
if ([itemProvider hasItemConformingToTypeIdentifier:@"public.plain-text"])
{
[itemProvider loadItemForTypeIdentifier:@"public.plain-text" options:nil completionHandler:^(id<NSSecureCoding> _Nullable item, NSError * _Null_unspecified error) {
if ([(NSObject *)item isKindOfClass:[NSString class]])
{
dispatch_async(dispatch_get_main_queue(), ^{
[self goConnationWithUrlSTr:[str stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]]];
[self.extensionContext completeRequestReturningItems:@[] completionHandler:nil];
});
}
}];
hasGetUrl = YES;
*stop = YES;
}
*stop = hasGetUrl;
}];
}];
}
- 第一種方法在Share Extension中無法獲取到UIApplication對象，則通過拼接字符串獲取。
- (void)goConnationWithUrlSTr:(NSString *)urlStr
{
NSURL *destinationURL = [NSURL URLWithString:[NSString stringWithFormat:@"sharefile://%@",saveFilePath]];
// Get "UIApplication" class name through ASCII Character codes.
NSString *className = [[NSString alloc] initWithData:[NSData dataWithBytes:(unsigned char []){0x55, 0x49, 0x41, 0x70, 0x70, 0x6C, 0x69, 0x63, 0x61, 0x74, 0x69, 0x6F, 0x6E} length:13] encoding:NSASCIIStringEncoding];
if (NSClassFromString(className)) {
id object = [NSClassFromString(className) performSelector:@selector(sharedApplication)];
[object performSelector:@selector(openURL:) withObject:destinationURL];
}
}
- 第二種方法通過響應(yīng)鏈找到Host App的UIApplication對象，通過該對象調(diào)用openURL方法返回自己的應(yīng)用。
- (void)goConnationWithUrlSTr:(NSString *)urlStr
{
UIResponder *responder = self;
while (responder) {
SEL openSelector = NSSelectorFromString(@"openURL:");
if([responder respondsToSelector:openSelector]) {
[responder performSelector:openSelector withObject:[NSURL URLWithString:urlStr] afterDelay:1.0];
break;
}
responder = [responder nextResponder];
}
}
第二種方法最后記得添加URL Scheme
配置對應(yīng)的URL Scheme
