嘿,我嘗試ping我的服務器和檢查應用程序的版本 - 一切順利,到目前爲止:的Objective-C不能在IF語句中使用stringWithContentsOfURL數據
NSURL *url = [NSURL URLWithString:@"http://thetalkingcloud.com/static/ping_desktop_app.php?v=1.1"];
NSError *theNetworkError;
NSString *content = [NSString stringWithContentsOfURL:url encoding:NSASCIIStringEncoding error:&theNetworkError];
//make sure something was returned
if (!content) {
//didn't connect
//my code that goes here is all fine and works
} else {
//there was some content returned by the server
//this NSLog prints out the expected data ('success' without the quotes)
NSLog(@"server returned data: >|%@|<", content);
//PROBLEM:
//neither of these two EVER become true, even when the server DOES return success or update
//connected, check what the server returned
if (content == @"success") {
NSLog(@"all went perfect");
} else if (content == @"update") {
NSLog(@"version error");
}
}
的IF語句AREN因爲某種原因不工作,任何人都可以幫我解決問題嗎? 謝謝。
非常感謝這個修好:) – 2009-10-10 12:59:59
