用于储蓄，下面的代码文件目录使用PDF。

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
     NSString *documentsDirectory = [paths objectAtIndex:0]; 
     NSString *localFilePath = [documentsDirectory stringByAppendingPathComponent:@"data.pdf"]; 

     NSData *thedata = [NSData dataWithContentsOfURL:[NSURL URLWithString:`ADD URL OF PDF DATA`]]; 

     [thedata writeToFile:localFilePath atomically:YES]; 

检索pdf使用下面的代码。

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
      NSString *documentsDirectory = [paths objectAtIndex:0]; 
      NSString *localFilePath = [documentsDirectory stringByAppendingPathComponent:@"data.pdf"]; 
if ([[NSFileManager defaultManager] fileExistsAtPath:localFilePath]) { 
      NSData *data = [NSData dataWithContentsOfFile:localFilePath]; 
     }
