Ich bin völlig neu bei HighCharts und ich verwiesen Beispiel http://blog.li-labs.com/developing-ios-apps-with-custom-charting/ und versuchte das gleiche, aber auf iPad Simulator bekomme ich einen leeren Bildschirm.Wie Sie Highcharts auf UIWebView in iOS hinzufügen?
Ich habe Fragen auf Stack-Overflow verwiesen, aber es funktioniert immer noch nicht. Kann mir jemand sagen, wo ich falsch liege.

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];
}
