调用视图控制器connectiondidfinish委托NSURLConnection中的另一个类
调用视图控制器connectiondidfinish委托NSURLConnection中的另一个类
提问于 2012-01-17 19:26:47
正在尝试在NSUrlConection的connectiondidfinish委托方法中启动视图控制器
//Sprequest.m继承自nsobject
- (void)connectionDidFinishLoading:(NSURLConnection *)conn {
NSLog(@"connectionDidFinishLoading ");
if(nStatus == 401)
{
NSLog(@"called maincontroller to launch dvrview");
MainController *mainview =[[MainController alloc] init];
[mainview reponseFromServer];
}
}
//maincontroller.m from viewcontroller
-(void)reponseFromServer
{
NSLog(@"response from server - main controller ");
dvrView *dvrObj = [[dvrView alloc]initWithNibName:@"dvrView" bundle:nil];
[self.navigationController pushViewController:dvrObj animated:YES];
}无法加载此dvr视图

Sprequest.m is inherited from NSObject , its not a viewController subclass so you cant use
[self.navigationController pushViewController:dvrObj animated:YES];在Sprequest.m中，您可以像这样从appdelegate中获取navigationController对象
((AppDelegate *)[UIApplication sharedApplication].delegate).navigationController然后使用
[((AppDelegate *)[UIApplication sharedApplication].delegate).navigationController pushViewController:dvrObj animated:YES];页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
