- (void)oneClick{ [NSThread detachNewThreadSelector:@selector(doSomething:) toTarget:self withObject:@"oneClick"];}-(void)doSomething:(NSString*) str{ NSLog(@"%@",str);}- (void)twoClick{ NSThread* myThread = [[NSThread alloc] initWithTarget:self selector:@selector(doSomething:) object:@"twoClick"]; [myThread start];} |
NSOperation适合需要复杂的线程调度的方法，然后它默认是使用主线程不会创建子线程
