我是 HighCharts 的新手，我引用了示例 http://blog.li-labs.com/developing-ios-apps-with-custom-charting/并尝试了同样的方法，但在 iPad 模拟器上我得到了一个空白屏幕。
我已经提到了有关堆栈溢出的问题，但它仍然无法正常工作。 谁能告诉我哪里出错了。

How to add and use the Javascript libraries in XCode
Here is a simple view of how I handle the code and data within XCode.
Download the Javascript reporting package from your preferd chart site. In my case: http://www.highcharts.com/download
Add or import the files into XCode resources. (I suggest creating a group called JS).
When adding a resource to XCode it will generally be marked as being needed to be compiled. Ensure that the files are not listed as being “Compiled”. The easiest way is to simply drag the files from Targets -> Your Project Name -> Compiled Sources into Targets -> Your Project Name -> Copy Bundle Resources.
Create a test html file or simply import one from your HighChart (or any other javascript chart library) examples folder. In my case I name it hcpie.html
Ensure that any file references in the tags do not recurse or move into any folder (even if they are in one in your project). e.g.
RIGHT =
WRONG =
- Create a UIWebView within Interface Designer and link it to your view (in my case I named it chart1). e.g.
@interface FirstViewController : UIViewController { IBOutlet UIWebView *chart1; }
@end
Simply reference the HTML example file when loading.
- (void)viewDidLoad {
NSString *pathOfFile = [[NSBundle mainBundle] pathForResource:@”hcpie” ofType:@”html”]; NSString *htmlText = [NSString stringWithContentsOfFile:pathOfFile encoding:NSUTF8StringEncoding error:nil];
NSURL *baseURL = [NSURL fileURLWithPath:pathOfFile];
[chart1 loadHTMLString: htmlText baseURL:baseURL];
[super viewDidLoad];
}
最佳答案
步骤:-
1) 首先只创建一个 html 文件并执行必要的代码，或者为了试用可以从包 http://www.highcharts.com/download 中获得的示例中复制 html 代码。
2) 确保 html 中的脚本应该有正确的 .js 链接
例如:- <script src="http://code.highcharts.com/highcharts.js"></script>
或
如果你想在本地给它你可以写<script src="highcharts.js"></script>
但请确保 .js 文件位于您的应用程序文件夹中。
3) NSString *htmlFile = [[NSBundle mainBundle] pathForResource:@"graph" ofType:@"html"];
NSString* htmlString = [NSString stringWithContentsOfFile:htmlFile encoding:NSUTF8StringEncoding error:nil];
[obj loadHTMLString:htmlString baseURL:nil]; // Webview *obj;
希望对您有所帮助。在我的例子中它的工作。
