这段代码内存泄漏
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]];
////htmpath，参数是字符串。
///fileurl 是 nsurl，在此我调用为结果附加两个字符串。 ///numberTextField.text 是将使用此 html 实现更多功能的文本字段。

////htmpath,params are strings.
///fileurl is nsurl and in this i m calling appending two strings for the result.
///numberTextField.text is the textfield that will use this html for further functionality.

您已经分配了“params”但没有释放它。
您应该释放每个分配的对象。
you have allocated the "params" and did not released it.
you should release every allocated object.
