出于某种原因,这适用于运行 iOS 6+ 的模拟器,但不适用于运行 iOS 5+ 的实际 iPad。当我在 iPad 上运行我的应用程序时,它给了我这个错误(和其他错误)。
Error parsing JSON: Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (Badly formed object around character 316.) UserInfo=0x650260 {NSDebugDescription=Badly formed object around character 316.}
JSON used is this (which is passed from Javascript): {"functionname":"setItem","args":{"key":"http://localhost:3000/assets/tasks/task.js","value":"function Task(){this.steps=new Array,this.completed=!1,this.loaded=!1,this.stepCount=-1,this.points=0,this.newpoints=0,this.prevpoints=0,this.circleGesture=!1,this.customGesture=!1,this.subtaskCounter=0,this.className=/"/"}(goes on for a while since it is a js script)"}}
在iOS中将json字符串转换为json的代码
if ([[urlStr lowercaseString] hasPrefix:protocolPrefix])
{
//strip protocol from the URL. We will get input to call a native method
urlStr = [urlStr substringFromIndex:protocolPrefix.length];
//Decode the url string
urlStr = [urlStr stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSError *jsonError;
//parse JSON input in the URL
NSDictionary *callInfo = [NSJSONSerialization
JSONObjectWithData:[urlStr dataUsingEncoding:NSUTF8StringEncoding]
options:0
error:&jsonError];
//check if there was error in parsing JSON input
if (jsonError != nil)
{
NSLog(@"Error parsing JSON: %@",[jsonError debugDescription]);
NSLog(@"%@", urlStr);
return NO;
}
....
}
咖啡脚本
callNativeFunction: (func, args, callback)->
if global_phone_os == 'ios'
url = "js2native://"
callInfo = {}
callInfo.functionname = func
if args?
callInfo.args = args
if callback?
cid = Math.random().toString(36).substr(2,10)
@callback[cid] = callback
callInfo.callback_id = cid
url += JSON.stringify callInfo
@openCustomURLinIFrame url
任何想法如何让它在模拟器和实际设备上工作?
更新
到目前为止,我想我已经解决了。如果我这样做了,这将被标记为答案。我必须在咖啡脚本中执行以下操作:
url += encodeURIComponent JSON.stringify callInfo
那有所作为。
谢谢。
