[英]when i am using 3 view on viewcontroller it get slow in objective c
我在一个UIViewController上使用3视图。 因此，我在viewDidLoad（）中有很多代码，例如：
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.

它的工作要慢得多。 有什么办法可以加快速度吗？
ViewName *Incedent =[[ViewName alloc] initWithNibName:@"ViewName" bundle:nil];
[self.navigationController pushViewController:Incedent animated:YES];
我已经将此代码用于pushviewcontroller。
你需要评估你的代码做什么，并找出它是缓慢的。 我不知道此方法在做什么，但我敢打赌：
[self testInternetConnection];
是问题之一。 注释掉该行，然后看看会发生什么。
