iOS多线程应用开发中使用NSOperation类的基本方法

#import "YYViewController.h"

@interface YYViewController ()

@end

复制代码
@implementation YYViewController

 

- (void)viewDidLoad
{
    [super viewDidLoad];
    
    //创建NSBlockOperation操作对象
    NSBlockOperation *operation=[NSBlockOperation blockOperationWithBlock:^{
        NSLog(@"NSBlockOperation------%@",[NSThread currentThread]);
    }];
    
    
    //开启执行操作
    [operation start];
}
@end
