如何获得的iOS appStoreReceiptURL进入基地64恩codeD字符串？ [英] How to get iOS appStoreReceiptURL into Base 64 Encoded String?
本文介绍了如何获得的iOS appStoreReceiptURL进入基地64恩codeD字符串？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想用appStoreReceiptURL看到购买的应用程序的人的版本。我怎样才能成为一个字符串呢？
我被从商店下载应用程序，然后运行从X code中的应用程序的新版本测试这一点。以下是我已经试过：
NSURL * receiptUrl = [[一个NSBundle mainBundle] appStoreReceiptURL]
的NSLog（@receiptUrl％@，[receiptUrl路径]）;
如果（[的NSFileManager defaultManager] fileExistsAtPath：[receiptUrl路径]）{
的NSLog（@存在）;
NSError *错误;
* NSString的receiptString = [[NSString的页头] initWithContentsOfFile：[receiptUrl路径]编码：NSUTF8StringEncoding错误：＆放大器;错误]
如果（receiptString ==无）{
的NSLog（@错误：％@，[错误localizedDescription]）;
}其他{
的NSLog（@回执：％@，receiptString）;
}}其他{
的NSLog（@不存在）;
}
这是我所得到的：
receiptUrl的/ var /移动/应用/ E612F261-2D30-416E-BF82-F24xxxx8860 / StoreKit /收据
存在
错误：操作无法完成。 （可可错误261.）
解决方案
我想通了，关键是要阅读收据作为数据基础，然后带64 code将其从数据。这里是为我工作，如果它可以帮助任何人。也感谢这个线程基地64编码： NSData的转换为Base64

I want to use appStoreReceiptURL to see which version of the app someone purchased. How can I get this into a string?
I'm testing this by downloading the app from the store, then running a new version of the app from Xcode. Here is what I've tried:
NSURL *receiptUrl = [[NSBundle mainBundle] appStoreReceiptURL];
NSLog(@"receiptUrl %@",[receiptUrl path]);
if ([[NSFileManager defaultManager] fileExistsAtPath:[receiptUrl path]]) {
NSLog(@"exists");
NSError *error;
NSString *receiptString = [[NSString alloc] initWithContentsOfFile:[receiptUrl path] encoding:NSUTF8StringEncoding error:&error];
if (receiptString == nil) {
NSLog(@"Error: %@", [error localizedDescription]);
} else {
NSLog(@"Receipt: %@",receiptString);
}
} else {
NSLog(@"does not exist");
}
This is what I get:
receiptUrl /var/mobile/Applications/E612F261-2D30-416E-BF82-F24xxxx8860/StoreKit/receipt
exists
Error: The operation couldn’t be completed. (Cocoa error 261.)
解决方案
I figured out the trick is to read the receipt as data then base 64 encode it from the data. Here's what worked for me if it helps anyone else. Also thanks to this thread for the base 64 encoding: Converting NSData to base64
