代码关闭App
方法一：
- (void)exitApplication{
AppDelegate *app = (AppDelegate *)[UIApplication sharedApplication].delegate;
UIWindow *window = app.window;
[UIView animateWithDuration:1.0f animations:^{
window.alpha = 0;
window.frame = CGRectMake(0, window.bounds.size.width, 0, 0);
} completion:^(BOOL finished) {
exit(0);
}];
}
方法二：
- (void)exitApplication {
[UIView beginAnimations:@"exitApplication" context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationDelegate:self];
// [UIView setAnimationTransition:UIViewAnimationCurveEaseOut forView:self.view.window cache:NO];
AppDelegate *delegate = (AppDelegate *)[UIApplication sharedApplication].delegate;
[UIView setAnimationTransition:UIViewAnimationCurveEaseOut forView:delegate.window cache:NO];
[UIView setAnimationDidStopSelector:@selector(animationFinished:finished:context:)];
//self.view.window.bounds = CGRectMake(0, 0, 0, 0);
delegate.window.bounds = CGRectMake(0, 0, 0, 0);
[UIView commitAnimations];
}
- (void)animationFinished:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context {
if ([animationID compare:@"exitApplication"] == 0) {
exit(0);
}
}
配置后台运行模式
在工程的info.plist 文件中，可以通过添加Required background modes (后台工作模式)属性，来实现后台运行一些操作，比如蓝牙、音频、视频、网络处理等。
