#import <UIKit/UIKit.h>
@interface ELCUIApplication : UIApplication
{
NSTimer *_idleTimer;
NSInteger timeCount;
}
@end
#import "ELCUIApplication.h"
@implementation ELCUIApplication

[super sendEvent:event];
if (_idleTimer==nil) {
[self resetIdleTimer];
}
NSSet *allTouches = [event allTouches];
if ([allTouches count] > 0) {
UITouchPhase phase = ((UITouch *)[allTouches anyObject]).phase;
if (phase == UITouchPhaseBegan) {
[self resetIdleTimer];
}
}
}
- (void)resetIdleTimer
{

if (_idleTimer==nil) {
_idleTimer = [NSTimer timerWithTimeInterval:1 target:self selector:@selector(idleTimerExceeded) userInfo:nil repeats:YES];
}
NSRunLoop* run=[NSRunLoop currentRunLoop];
[run addTimer:_idleTimer forMode:NSDefaultRunLoopMode];
}
- (void)idleTimerExceeded
{

if (timeCount>=0) {
NSLog(@"%ld",(long)timeCount);
}else{
NSLog(@"锁频通知发出");

}
}
@end

#import "ELCUIApplication.h"
int main(int argc, char * argv[]) {
