我正在使用 RESTKIT 对象管理器从我的服务器获取信息。我的实现代码片段如下:
-(void)getObjects
{
//Instantiate the RestKit Object Manager
RKObjectManager *sharedManager = [RKObjectManager sharedManager];
//show the spinner
[self showLoading];
//call server with the resourcepath
[sharedManager loadObjectsAtResourcePath:self.resourcePath delegate:self];
}
- (void)objectLoader:(RKObjectLoader*)objectLoader didLoadObjects:(NSArray*)objects
{
// handling in scenarios of empty arrays
if ( [objects count]==0 ){
[self hideLoading];
if (emptyHandler){
emptyHandler();
}else{
[self standardEmptyHandling];
}
return;
}
// planned failure
if ( [[objects objectAtIndex:0] isKindOfClass:[Failure class]]){
NSAssert([objects count]==1,@"object returned is type failure, but there are more than one object in it");
failureObject=[objects objectAtIndex:0];
[self hideLoading];
[self standardErrorHandling];
return;
}
//return completion block to caller
completionHandler(objects);
}
但是,在某些情况下,可能会出现服务器错误或可达性错误,这会导致进程在终止之前继续尝试很长时间(微调器将显示更长的时间_。
有没有办法在我的实现中设置超时持续时间,以便如果服务器在 20 秒内没有响应,我可以提示用户重试?
