NSJSONSerialization——IOS5自带
JSONObjectWithData创建json对象
#pragma mark - ASIHTTPRequestDelegate
- (void)requestFinished:(ASIHTTPRequest *)request
{
NSError *error;
NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:request.responseData options:kNilOptions error:&error];
NSArray *movieArray = [jsonDict objectForKey:@"subjects"];
// NSDictionary *jsonDict = [request.responseString JSONValue];
// NSArray *movieArray = jsonDict[@"subjects"];
for (NSDictionary *dict in movieArray)
{
SYMovieModel *model = [[SYMovieModel alloc] init];
model.movieName = dict[@"title"];
model.movieYear = dict[@"year"];
model.movieImage = dict[@"images"][@"large"];
[_saveDataArray addObject:model];
}
//刷新表
[_tableView reloadData];
}
获取webView中的json
- (void)webViewDidFinishLoad:(UIWebView *)webView{
NSString *jsonStr = [self.webView stringByEvaluatingJavaScriptFromString:@"document.body.innerHTML"];
NSString *cmd = [NSString stringWithFormat:@"eval(%@).userId", jsonStr];
NSString *str = [self.webView stringByEvaluatingJavaScriptFromString:cmd];
cmd = [NSString stringWithFormat:@"eval(%@).result", jsonStr];
str = [self.webView stringByEvaluatingJavaScriptFromString:cmd];
if ([str isEqualToString:@"Success"]){
NSLog(@"Success");
[self dismissViewControllerAnimated:NO completion:^{}];
}
}
