我有以下的NSString:的NSString没有出现正常
NSString* searchURL = [NSString stringWithFormat:@"http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quotes%20where%20symbol%20in%20(%22%@%22)%0A%09%09&format=json&env=http%3A%2F%2Fdatatables.org%2Falltables.env&callback=",symbol];
NSLog(@"URL IS: %@", searchURL);
貌似%22不被包含在打印时:
URL IS: http://query.yahooapis.com/v1/public/yql?q=select220from2ahoo.finance.quotes2here `º≠ymbol [email protected]&format=json&env=http0X1.8CFB8P-1023-1.9907460.000000datatables.org-1.990746alltables.env&callback=
我怎样才能确保% 22是否包含在我的字符串中?
