//
#import "ViewController.h"

@interface ViewController ()
@property (nonatomic, strong)ZFPermenantThread *thread;
@end
@implementation ViewController
- (void)viewDidLoad {

// Do any additional setup after loading the view.
self.thread = [[ZFPermenantThread alloc] init];
// [self.thread run];
}
- (void)touchesBegan:(NSSet *)toucheswithEvent:(UIEvent*)event {
[self.thread executeTask:^{
NSLog(@"执行任务");
}];
}
- (void)test{
}
- (void)stop{
[self.threadstop];
}
- (void)dealloc {
// [self.thread stop];
}
@end
