使用UIButton的enabled或userInteractionEnabled
使用UIButton的enabled属性, 在点击后, 禁止UIButton的交互, 直到完成指定任务之后再将其enabled即可.
[btn addTarget:self action:@selector(nextStop:) forControlEvents:UIControlEventTouchUpInside];
- - (void)nextStop:(UIButton *)sender {
- sender.enabled = NO;
- [self btnClicked];
- }
- - (void)btnClicked {
- dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
- NSLog(@"btnClicked");
- btn.enabled = YES;
- });
- }
