NSString writeToFile operation couldn't be completed
- by Chonch
Hey,
I have an xml file in my application bundle. I want to copy it to the documents folder at installation and then, every time the app launches, get the newest version of this file from the Internet. I use this code:
// Check if the file exists in the documents folder
NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
if (![[NSFileManager defaultManager] fileExistsAtPath:[documentsPath stringByAppendingPathComponent:@"fileName.xml"]])
// If not, copy it there (from the bundle)
[[NSFileManager defaultManager] copyItemAtPath:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"OriginalFile.xml"]
toPath:[documentsPath stringByAppendingPathComponent:@"fileName.xml"] error:nil];
// Get the newest version of the file from the server
NSURL *url=[[NSURL alloc] initWithString:@"http://www.sitename.com/webservice.asmx/webserviceName"];
NSString *results = [[NSString alloc] initWithContentsOfURL:url];
// Replace the current version with the newest one, only if it is valid
if (results != nil)
[results writeToFile:[documentsPath stringByAppendingPathComponent:@"fileName.xml"] atomically:NO encoding:NSStringEncodingConversionAllowLossy error:nil];
The problem is that the writeToFile command always returns NO and the file's contents remain identical to the original file I included in my app bundle. I checked the value of results and it's correct. I also made sure that the app does perform the writeToString command, but still, it always returns NO.
Can anybody tell me what I'm doing wrong?
Thanks,
