我一直收到错误“预期标识符”

Question

@implementation SecondViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    webView.userInteractionEnabled = TRUE;
    [webView loadRequest: [[NSURLRequest alloc] initWithURL: [[NSURL alloc] initWithString: [[[@"http//:www.mobile-boome.weebly.com/boome-webviwer.html" ]]];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

问题在第8行：xcode表示预期的标识符，但我无法理解问题是什么，所以我无法解决它！ 感谢

Answer 1

你在这一行有额外的括号。此外，NSURLRequest和NSURL都有类方法，可以简化构造类的实例。

试试这个：

[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http//:www.mobile-boome.weebly.com/boome-webviwer.html"]]];
