开发要求：
联网的时候，有协议数据的时候从上往下弹出界面，每个用户必须同意协议才能使用app，否则退出应用（exit(0)）;
我的解决方案：在comment类里，写个类方法，实现
if (![[NSUserDefaults standardUserDefaults] boolForKey:@"showUserAgreementViewController"]) {
CATransition *transition = [CATransition animation];
transition.duration = 0.3f;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionMoveIn;
transition.subtype = kCATransitionFromBottom;
[ESControllerManager pushViewController:@"ESUserAgreementViewController" Parameters:@{@"title":daRenAgreementTitle,@"content":daRenAgreementContent,@"ID":@(daRenAgreementID)} Animated:NO];
[[ESControllerManager getRootNavigationController].view.layer addAnimation:transition forKey:nil];
}
});
bug：
1，当手机没电，强制关机等突然中止应用的时候，再此打开应用时，协议不能弹出；
为防止界面弹出多次，我在本地保存一个bool值，标示界面是否在弹出boolForKey:@"showUserAgreementViewController"，问题就在这里，如果突然中止应用，这个bool值还是yes,界面如何能弹出来呢
2，当登陆应用的时候，弹出主页，协议不弹出；
这种情况，主界面第二次弹出还带有动画，其实还是蛮好玩的，这个问题是在push上，当两个界面同时弹出时，一个界面覆盖另一个界面，显示出来的界面就有一定的不确定行
解决方案：
应用代码：
if (![ESUserAgreementViewController IsShow]) {
[ESUserAgreementViewController Show:daRenAgreementTitle Content:daRenAgreementContent ID:daRenAgreementID];
}
界面搭建：将界面放到一个window上，界面是否弹出标示 设置成静态变量
static UIWindow* window;
static BOOL isShow;
@implementation ESUserAgreementViewController
+(BOOL)IsShow
{
return isShow;
}
+(void)Init
{
if(!window)
{
window=[[UIWindow alloc]initWithFrame:CGRectMake(0, 0, ESWidth, ESHeight)];
window.windowLevel=1499.9;
window.hidden=YES;
[window makeKeyAndVisible];
}
}
+(void)Show:(NSString*)title Content:(NSString*)content ID:(int)ID
{
isShow=YES;
[ESUserAgreementViewController Init];
ESUserAgreementViewController* viewController=[[ESUserAgreementViewController alloc]init];
[viewController setParameters:@{@"title":title,@"content":content,@"ID":@(ID)}];
for (UIView* view in window.subviews) {
[view removeFromSuperview];
}
[window setRootViewController:viewController];
[window addSubview:viewController.view];
window.frame=CGRectMake(0, -ESHeight, ESWidth, ESHeight);
window.hidden=NO;
[UIView animateWithDuration:0.3 animations:^{
window.frame=CGRectMake(0, 0, ESWidth, ESHeight);
}];
}
+(void)Hide
{
isShow=NO;
[UIView animateWithDuration:0.3 animations:^{
window.frame=CGRectMake(0, -ESHeight, ESWidth, ESHeight);
}];
}
