I want to do following list.
I can get Response. But, It's not work 'alert' correctly in callback function(freeze).
Why do like that?
Thank you.
#import "TestViewController.h"
#import "AFNetworking.h"
@interface TestViewController ()
@end
@implementation TestViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization]
[self initWebView] ;
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)initWebView{
self.webView = [[UIWebView alloc] initWithFrame:SCREEN_APPLICATIONFRAME] ;
[self.view addSubview:self.webView] ;
self.webView.delegate = self ;
[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"SOME_HTML"]]] ;
}
-(BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)
request navigationType:(UIWebViewNavigationType)navigationType
{
if ([ request.URL.scheme isEqualToString:@"native" ]) {
if ([request.URL.host isEqualToString:@"foo"]) {
NSURL *url = [[NSURL alloc]initWithString:@"SOME_JSON_RESPONSE_URL"] ;
NSURLRequest *request = [NSURLRequest requestWithURL:url];
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
NSLog(@"SUCCESS") ;
[self.webView stringByEvaluatingJavaScriptFromString:@"cbFoo('OK')"] ;
} failure:^(NSURLRequest *request, NSURLResponse *response, NSError *error, id JSON){
NSLog(@"ERROR: %@",error) ;
[self.webView stringByEvaluatingJavaScriptFromString:@"cbFoo('NG')"] ;
}];
[operation start] ;
}
return NO;
}
// 通常のschemeの場合は、フックせずそのまま処理を続ける
else {
return YES;
}
}

<head>
<meta http-equiv="Content-Type" content="text/html; charset= UTF-8">
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script type="text/javascript">
// callback from native
function cbFoo(result){
alert(result) ; // FREEZE!!
alert('1st') ;
alert('2nd') ;
}
</script>

<body>
<a href="native://foo" >Native Func</a><br>

Finally I write following code.
NSString *str = [NSString stringWithFormat:@"setTimeout(function(){cbGetCommentData('%@');},0)", text] ;
[self.webView stringByEvaluatingJavaScriptFromString:str] ;
