我添加了以下代码以从 iCloud 备份中排除文件,但我的应用程序仍然被拒绝:
- (BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL
{
if (&NSURLIsExcludedFromBackupKey == nil) { // iOS <= 5.0.1
const char* filePath = [[URL path] fileSystemRepresentation];
const char* attrName = "com.apple.MobileBackup";
u_int8_t attrValue = 1;
int result = setxattr(filePath, attrName, &attrValue, sizeof(attrValue), 0, 0);
return result == 0;
} else { // iOS >= 5.1
NSLog(@"%d",[URL setResourceValue:[NSNumber numberWithBool:YES] forKey:NSURLIsExcludedFromBackupKey error:nil]);
return [URL setResourceValue:[NSNumber numberWithBool:YES] forKey:NSURLIsExcludedFromBackupKey error:nil];
}
}
在模拟器的情况下,我将以下 url 作为 NSURL 传递:
file:///Users/TEST/Library/Application%20Support/iPhone%20Simulator/5.1/Applications/62854BAB-AB51-4771-895F-28C61983A7AC/Documents/MyFolder”
有人可以建议我的错误在哪里吗?
