当设备脱机时,我一直在尝试使用AFNetworking来排列HTTP请求的解决方案,所以当它返回在线时,请求完成.据我所了解,这可以设置setReachabilityStatusChangeBlock：参数.
到目前为止,这是我所拥有的：
// ViewController.h
@interface XYZTicketViewController : UIViewController<NSURLConnectionDelegate> // This is from before I started using AFNetworking,I'm intending to change all the requests to use AFNetworking in the near future.
@end
// ViewController.m
(...)
#import <AFHTTPRequestOperationManager.h>
#import <AFNetworkReachabilityManager.h>
(...)
@interface XYZTicketViewController ()
- (void)viewDidLoad
(...)
{
NSURL *baseURL = [NSURL URLWithString:@"http://54.213.167.202"];
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:baseURL];
NSOperationQueue *operationQueue = manager.operationQueue;
[manager.reachabilityManager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
switch (status) {
case AFNetworkReachabilityStatusReachableViaWWAN:
case AFNetworkReachabilityStatusReachableViaWiFi:
[operationQueue setSuspended:NO];
NSLog(@"WIFI");
break;
case AFNetworkReachabilityStatusNotReachable:
default:
[operationQueue setSuspended:YES];
NSLog(@"oflline,baby");
break;
}
}];
NSDictionary *parameters = @{@"action": @"login",@"user": @"mail.address@gmail.com",@"pass": @"howdoyouturnthison"};
[manager GET:@"http://54.213.167.202/api.PHP" parameters:parameters success:^(AFHTTPRequestOperation *operation,id responSEObject) {
NSLog(@"JSON: %@",responSEObject);
} failure:^(AFHTTPRequestOperation *operation,NSError *error) {
NSLog(@"Error: %@",error);
}];
(...)
}
我找不到任何例子,但我读了here这是可能的,但到目前为止,当在线状态发生变化时,任何事情都会发生.
希望你能帮助我
解决方法
在调用setReachabilityStatusChangeBlock之前,需要调用startMonitoring
[manager.reachabilityManager startMonitoring];
如果您使用的是AFNetworking 2.0,我建议如下：
[[AFNetworkReachabilityManager sharedManager] startMonitoring];
[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
DLog(@"Reachability: %@",AFStringFromNetworkReachabilityStatus(status));
switch (status) {
case AFNetworkReachabilityStatusReachableViaWWAN:
case AFNetworkReachabilityStatusReachableViaWiFi:
[operationQueue setSuspended:NO];
NSLog(@"WIFI");
break;
case AFNetworkReachabilityStatusNotReachable:
default:
[operationQueue setSuspended:YES];
NSLog(@"offline,baby");
break;
}
}];
