ViewController *view=[[ViewController alloc] init]; [self.navigationController pushViewController:controller animated:YES]; [view release];
这段代码中的view是保存在内存中还是？

view是保存在内存中的
ViewController *view=[[ViewController alloc] init]; // view retain count = 1;
[self.navigationController pushViewController:controller animated:YES]; // view retain count = 2;
[view release]; // view retain count = 1;
