Question

In my app I have to read an XML file and display it in a UITextView. To do this I tried the code below. This code is resulting in a crash; can any one tell me the exact mistake? I hope I wrote well. Please help me out. Thank you.

-(IBAction)xmlParse{

    NSString *xmlPath=[[[[UIApplication sharedApplication]delegate] applicationDocumentDirectory]stringByAppendingPathComponent:@"xmlFile/toc.xml"];
    NSError *error=nil;
    NSString *fileContent=[NSString stringWithContentsOfFile:xmlPath usedEncoding:NSASCIIStringEncoding error:NULL];
    xmlDisplay.text=fileContent;

}

Answer 1

replace

NSString *fileContent=[NSString stringWithContentsOfFile:xmlPath usedEncoding:NSASCIIStringEncoding error:NULL];

with

NSString *fileContent=[NSString stringWithContentsOfFile:xmlPath encoding:NSASCIIStringEncoding error:NULL];

you should not ignore the assing argument 2 of 'stringWithContentsOfFile:usedEncoding:error:' makes pointer from integer without a cast warning the compiler shows you.
