Iphone 内存泄漏此代码

////htmpath，参数是字符串

///fileurl是nsurl，在这里我调用为结果附加两个字符串。 ///numberTextField.text是将使用此html实现进一步功能的文本字段。

您已分配了“参数”，但未将其释放

htmPath = [[NSBundle mainBundle] pathForResource:@"barcode" ofType:@"html"];
params = [[NSString alloc] initWithFormat:@"?data=%@",numberTextField.text];
fileURL = [NSURL URLWithString:[[[NSURL fileURLWithPath:htmPath] absoluteString] stringByAppendingString:params]];

[self.barView loadRequest:[NSURLRequest requestWithURL:fileURL]];

您应该释放每个分配的对象

params = [[NSString alloc] initWithFormat:@"?data=%@",numberTextField.text];
