先閱讀官方說明：
使用方法：
#import “sys/xattr.h”
- (BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL
{
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;
}
- (void)addSkipBackupAttributeToPath:(NSString*)path {
u_int8_t b = 1;
setxattr([path fileSystemRepresentation], “com.apple.MobileBackup”, &b, 1, 0, 0);
}
