[parser setDelegate：self];

Question

NSString* username = [[NSUserDefaults standardUserDefaults] stringForKey:@"username_preference"];
NSString* accountPassword = [[NSUserDefaults standardUserDefaults] stringForKey:@"password_preference"];
NSString* urlString = [NSString stringWithFormat:@"https://%@:%@@testing.com/test.php",username,accountPassword];    
NSURLRequest* request = [NSURLRequest requestWithURL:[NSURL URLWithString:urlString]];
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response;

int status = [httpResponse statusCode];
if (!((status >= 200) && (status < 300))) {
    NSLog(@"Connection failed with status %@", status);
    [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
} else {
    NSXMLParser* xmlparser = [[NSXMLParser alloc] initWithData: response];
    NSLog(@"at parser %@", xmlparser);
    [parser setDelegate:self];

代码的最后一行显示错误并建议“更改解析器暂停”!!请帮忙!!

Answer 1

嗯，是不是因为你的解析器变量名为'xmlparser'而不是'parser'？

Answer 2

将parser更改为xmlparser。
