(void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor clearColor];
[self initView];
SetRootViewControllerHandle *handle = [[SetRootViewControllerHandle alloc] init];
[handle setRootViewController];
}
源代碼是這樣定義的，創(chuàng)建的臨時(shí)變量；在SetRootViewControllerHandle.m文件中的方法實(shí)現(xiàn)如下-
(void)setRootViewController
{
if (self.isLogin) {// 登錄狀態(tài)
[self.viewModel initNetWorkOfGetUserInfo];} else {// 非登錄狀態(tài)
LoginViewController *VC = [[LoginViewController alloc] init];
VC.openType = OpenTypeRoot;
BaseNavigationController *naviC = [[BaseNavigationController alloc] initWithRootViewController:VC];
AppDelegateInstance.window.rootViewController = naviC;
}
}
在登錄狀態(tài)下，直接網(wǎng)絡(luò)請(qǐng)求數(shù)據(jù)后在進(jìn)行視圖控制器的變換操作，但是SetRootViewControllerHandle是臨時(shí)變量，代碼運(yùn)行后就直接銷毀了，但是網(wǎng)絡(luò)請(qǐng)求是異步操作，就導(dǎo)致網(wǎng)絡(luò)請(qǐng)求的對(duì)象提前釋放，導(dǎo)致的結(jié)果閃退或者無反應(yīng)，所以不應(yīng)該定義為臨時(shí)變量
@property (nonatomic,strong) SetRootViewControllerHandle *handle;
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor clearColor];
[self initView];
self.handle = [[SetRootViewControllerHandle alloc] init];
[self.handle setRootViewController];
}
增加對(duì)象的持有時(shí)間就好了咯
