剛開始干開發，那想法就是一個，實現功能， 然而到了后期，實現功能一經沒有什么太大的樂趣了，這時候編程的樂趣來自如何高效的實現功能， 下面說一說做推送的時候得到數據，不用廣播而是得到當前的vc或者說的到某一個vc的對象，開放加方法去做一些數據處理，接下來直接上代碼
獲得當前vc
1.以UITabBarController這種形式為工程基本框架的
if ([userInfo[@"extras"][@"PushType"] intValue] == 4 || [userInfo[@"extras"][@"PushType"] intValue] == 5) {
UITabBarController *main = ((UITabBarController*)self.window.rootViewController).selectedViewController;
if ([[main.viewControllers lastObject] isKindOfClass:NSClassFromString(@"DeviceViewController")]) {//設備頁面
NSLog(@"DeviceViewController");
DeviceViewController *deviceVC = (DeviceViewController *)[main.viewControllers lastObject];
[deviceVC refreshTem:userInfo[@"extras"]];
NSLog(@"%@",deviceVC.whereVC);
}else if ([[main.viewControllers lastObject] isKindOfClass:NSClassFromString(@"DeviceDetailViewController")]) {
DeviceDetailViewController *deviceVC = (DeviceDetailViewController *)[main.viewControllers lastObject];
[deviceVC jpushRefreshWith:userInfo[@"extras"]];
NSLog(@"DeviceDetailViewController");
}
}
2以 UISubNavigationController或者UINavigationController為框架的結構
UISubNavigationController * nav =(UISubNavigationController *) self.window.rootViewController;
if ([[nav.viewControllers lastObject] isKindOfClass:NSClassFromString(@"MessageViewController")])
{
return;
}
//當前的vc ： [nav.viewControllers lastObject]
尋找控制器中的某個vc
for (UIViewController *vc in nav.viewControllers) {
if ([vc isKindOfClass:[OrderNewViewController class]]) {
OrderNewViewController *vcc = (OrderNewViewController*)vc;
switch (alertView.tag) {
case 0:{
vcc.pushMark = @"0";
break;
}
case 1:{
vcc.pushMark = @"1";
break;
}
case 2:{
vcc.pushMark = @"2";
break;
}
}
if (![vc isEqual:[nav.viewControllers lastObject]]) {
[nav popToViewController:vcc animated:YES];
}else{
[vcc refreshVIewH];
}
return;
}
}
我覺得以上這些基本夠用了吧
開發類方法也就是把.m的方法像＋方法那樣在。h中寫一下， 不過這個是－方法.
一下是流傳很廣的獲得當前vc的方法， 雖然我沒用到，貼出來希望能幫到大家
1.
//獲取當前屏幕顯示的viewcontroller
- (UIViewController *)getCurrentVC
{
UIViewController *appRootVC = [UIApplication sharedApplication].keyWindow.rootViewController;
UIViewController *topVC = appRootVC;
if (topVC.presentedViewController) {
topVC = topVC.presentedViewController;
}
return topVC;
}
2
- (UIViewController *)getCurrentVC
{
UIViewController *result = nil;
UIWindow * window = [[UIApplication sharedApplication] keyWindow];
if (window.windowLevel != UIWindowLevelNormal)
{
NSArray *windows = [[UIApplication sharedApplication] windows];
for(UIWindow * tmpWin in windows)
{
if (tmpWin.windowLevel == UIWindowLevelNormal)
{
window = tmpWin;
break;
}
}
}
UIView *frontView = [[window subviews] objectAtIndex:0];
id nextResponder = [frontView nextResponder];
if ([nextResponder isKindOfClass:[UIViewController class]])
result = nextResponder;
else
result = window.rootViewController;
return result;
}
完畢
