我正在为具有临时分发的企业应用程序进行更新计划.

对于更新,Apple建议让用户访问HTML页面并点击链接:

href="itms-services://?action=download-manifest&url=http://example.com/?manifest.plist"

if (plistData) {
    NSLog(@"finished checking for update");
    NSError *error;
    NSPropertyListFormat format;
    NSDictionary *plist = [NSPropertyListSerialization propertyListWithData:plistData options:NSPropertyListImmutable format:&format error:&error];
    if (plist) {
        NSArray *items = [plist valueForKey:@"items"];
        NSDictionary *dictionary;
        if ([items count] > 0) {
            dictionary = [items objectAtIndex:0];
        }
        NSDictionary *metaData = [dictionary objectForKey:@"metadata"];

        float currentVersion = [[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"] floatValue];
        float newVersion = [[metaData objectForKey:@"bundle-version"] floatValue];
        NSLog(@"newVersion: %f, …
