错误消息：预期表达式？
错误消息：预期表达式？
我觉得这可能是一个愚蠢的错误，但我就是找不出来。有人能告诉我我错在哪里吗？？
-(void) receiveRecommendData {
//接收数据//
NSURL *getResultUrl = [NSURL URLWithString:@"http://phdprototype.tk/getResultData.php"];
NSData *data = [NSData dataWithContentsOfURL:getResultUrl];
[self getData:data];
NSDictionary *jsonToDict = json[0]; //[json objectAtIndex:0];
int pageNumber = [[jsonToDict objectForKey:@"recommendData"]intValue];
UIViewController *controller; //错误发生在这些代码上
switch (pageNumber) {
case 0:
controller = [self.storyboard instantiateViewControllerWithIdentifier:@"Collection_01ViewController"];
break;
case 1:
controller = [self.storyboard instantiateViewControllerWithIdentifier:@"Collection_01ViewController"];
break;
case 2:
controller = [self.storyboard instantiateViewControllerWithIdentifier:@"Collection_02ViewController"];
break;
case 3:
controller = [self.storyboard instantiateViewControllerWithIdentifier:@"Collection_03ViewController"];
break;
default:
break;
}
}
