- (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

- (void)threeClick{
// 1.创建NSInvocationOperation对象
NSInvocationOperation *op = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(run) object:nil];
// 2.调用start方法开始执行操作
[op start];
}
- (void)run
{
NSLog(@"------%@", [NSThread currentThread]);
}
- (void)fourClick{
NSBlockOperation *op = [NSBlockOperation blockOperationWithBlock:^{
// 在主线程
NSLog(@"1------%@", [NSThread currentThread]);
}];
// 添加额外的任务(在子线程执行)
[op addExecutionBlock:^{
NSLog(@"2------%@", [NSThread currentThread]);
}];
[op addExecutionBlock:^{
NSLog(@"3------%@", [NSThread currentThread]);
}];
[op addExecutionBlock:^{
NSLog(@"4------%@", [NSThread currentThread]);
}];
[op start];
