我有一个应用程序,我经常通过ad-hoc分发方法传递给测试人员。其中一些测试人员“关注”并且对配置文件和季度到期有足够的了解,并且可以(如果我忘了)给我一个重建新版本供他们测试的推动。
然而,有些用户似乎总是达到停止运行的程度,然后对此嗤之以鼻 - 尽管他们可能会忽略iOS级别的提醒。
我的问题是,我可以在运行时以编程方式获取到期日期并执行我自己的“应用内”警报或系统通知,以提醒他们下拉新版本吗?

您正在寻找类似
的内容"<key>ExpirationDate</key><date>2014-12-06T00:26:10Z</date>" in [[NSBundle mainBundle] pathForResource:@"embedded" ofType:@"mobileprovision"]
但要到那里并不容易!此代码可以改进,部分内容基于其他stackoverflow帖子。注意:另一种选择是在项目plist之间加载所有内容 和/ plist into ... plist(字典)。但由于我们已经在那里,我们只是手工找到兄弟姐妹。
- (NSString*) getExpiry{
NSString *profilePath = [[NSBundle mainBundle] pathForResource:@"embedded" ofType:@"mobileprovision"];
// Check provisioning profile existence
if (profilePath)
{
// Get hex representation
NSData *profileData = [NSData dataWithContentsOfFile:profilePath];
NSString *profileString = [NSString stringWithFormat:@"%@", profileData];
// Remove brackets at beginning and end
profileString = [profileString stringByReplacingCharactersInRange:NSMakeRange(0, 1) withString:@""];
profileString = [profileString stringByReplacingCharactersInRange:NSMakeRange(profileString.length - 1, 1) withString:@""];
// Remove spaces
profileString = [profileString stringByReplacingOccurrencesOfString:@" " withString:@""];
// Convert hex values to readable characters
NSMutableString *profileText = [NSMutableString new];
for (int i = 0; i < profileString.length; i += 2)
{
NSString *hexChar = [profileString substringWithRange:NSMakeRange(i, 2)];
int value = 0;
sscanf([hexChar cStringUsingEncoding:NSASCIIStringEncoding], "%x", &value);
[profileText appendFormat:@"%c", (char)value];
}
// Remove whitespaces and new lines characters
NSArray *profileWords = [profileText componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
//There must be a better word to search through this as a structure! Need 'date' sibling to <key>ExpirationDate</key>, or use regex
BOOL sibling = false;
for (NSString* word in profileWords){
if ([word isEqualToString:@"<key>ExpirationDate</key>"]){
NSLog(@"Got to the key, now need the date!");
sibling = true;
}
if (sibling && ([word rangeOfString:@"<date>"].location != NSNotFound)) {
NSLog(@"Found it, you win!");
NSLog(@"Expires: %@",word);
return word;
}
}
}
return @"";
}

快速版本:
// Returns `nil` if it fails
private func getProvisioningProfileExpirationDateAsString() -> String? {
guard
let profilePath = Bundle.main.path(forResource: "embedded", ofType: "mobileprovision"),
let profileData = try? Data(contentsOf: URL(fileURLWithPath: profilePath)),
// Note: We use `NSString` instead of `String`, because it makes it easier working with regex, ranges, substring etc.
let profileNSString = NSString(data: profileData, encoding: String.Encoding.ascii.rawValue)
else {
print("WARNING: Could not find or read `embedded.mobileprovision`. If running on Simulator, there are no provisioning profiles.")
return nil
}
// NOTE: We have the `[\\W]*?` check to make sure that variations in number of tabs or new lines in the future does not influence the result.
guard let regex = try? NSRegularExpression(pattern: "<key>ExpirationDate</key>[\\W]*?<date>(.*?)</date>", options: []) else {
print("Warning: Could not create regex.")
return nil
}
let regExMatches = regex.matches(in: profileNSString as String, options: [], range: NSRange(location: 0, length: profileNSString.length))
// NOTE: range `0` corresponds to the full regex match, so to get the first capture group, we use range `1`
guard let rangeOfCapturedGroupForDate = regExMatches.first?.range(at: 1) else {
print("Warning: Could not find regex match or capture group.")
return nil
}
let dateAsString = profileNSString.substring(with: rangeOfCapturedGroupForDate)
return dateAsString
}

在iOS 13中,它不起作用。 NSData的描述从
{0x30822755 06092a86 4886f70d 010702a0 ... 889bfcbe ed768bac }
到
{length = ..., bytes = 0x30822755 06092a86 4886f70d 010702a0 ... 889bfcbe ed768bac }
尝试以下代码:
NSData *data = ....;
NSUInteger dataLength = [data length];
NSMutableString *string =[NSMutableString stringWithCapacity:dataLength*2];
const unsigned char *dataBytes = [data bytes];
for (NSInteger idx = 0; idx < dataLength; ++idx)
{
[string appendFormat:@"%02x", dataBytes[idx]];
}

在 iOS 13 中,为了简化 Ttnka 的建议,您可以使用 profileData.debugDescription 来创建 profileString(来自最初发布的 Objective-C 代码):
NSString *profileString = [NSString stringWithFormat:@"%@", profileData.debugDescription];
答案 4 :(得分:0)
结合@Pierre-Francoys Brousseau 和@Ttnka 的回答:
- (NSString *) getAppExpiry
{
NSString *profilePath = [[NSBundle mainBundle] pathForResource:@"embedded" ofType:@"mobileprovision"];
// Check provisioning profile existence
if (profilePath)
{
// Get hex representation
NSData *profileData = [NSData dataWithContentsOfFile:profilePath];
NSString *profileString;
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 13.0)
{
NSUInteger dataLength = [profileData length];
NSMutableString *string =[NSMutableString stringWithCapacity:dataLength*2];
const unsigned char *dataBytes = [profileData bytes];
for (NSInteger idx = 0; idx < dataLength; ++idx)
{
[string appendFormat:@"%02x", dataBytes[idx]];
}
profileString = string;
}
else
{
profileString = [NSString stringWithFormat:@"%@", profileData];
// Remove brackets at beginning and end
profileString = [profileString stringByReplacingCharactersInRange:NSMakeRange(0, 1) withString:@""];
profileString = [profileString stringByReplacingCharactersInRange:NSMakeRange(profileString.length - 1, 1) withString:@""];
// Remove spaces
profileString = [profileString stringByReplacingOccurrencesOfString:@" " withString:@""];
}
// Convert hex values to readable characters
NSMutableString *profileText = [NSMutableString new];
for (int i = 0; i < profileString.length; i += 2)
{

int value = 0;
sscanf([hexChar cStringUsingEncoding:NSASCIIStringEncoding], "%x", &value);
[profileText appendFormat:@"%c", (char)value];
}
// Remove whitespaces and newline characters
