我有自己的类可以进行http调用,但是现在在iOS9中不赞成使用此方法:[NSURLConnetion sendAsynchronousRequest:queue:completionHandler:]
我正在尝试测试新的[NSURLSession dataTaskWithRequest:completionHandler:]
但是Xcode给出了一个错误,因为它找不到此方法。
Xcode编译器警告,不建议使用以下行:
'sendAsynchronousRequest:queue:completionHandler:' is deprecated: first deprecated in iOS 9.0 - Use [NSURLSession dataTaskWithRequest:completionHandler:] (see NSURLSession.h
新方法出错:
No known class method for selector 'dataTaskWithRequest:completionHandler:'
方法:
-(void)placeGetRequest:(NSString *)action withHandler:(void (^)(NSURLResponse *response, NSData *data, NSError *error))ourBlock {
NSString *url = [NSString stringWithFormat:@"%@/%@", URL_API, action];
NSURL *urlUsers = [NSURL URLWithString:url];
NSURLRequest *request = [NSURLRequest requestWithURL:urlUsers];
//[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:ourBlock];
[NSURLSession dataTaskWithRequest:request completionHandler:ourBlock];
}
任何的想法?
最佳答案
dataTaskWithRequest:completionHandler:
是实例方法,而不是类方法。您必须配置一个新 session 或使用共享的 session :
[[[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:ourBlock] resume];
关于ios - 弃用的: 'sendAsynchronousRequest:queue:completionHandler:' in iOS9,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/31219548/
