iOS 检测状态栏点击事件

 

 

当tableView.scrollsToTop=YES不管用时,可以使用以下方法实现点击状态栏使tableView滚动到顶部。

 

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [super touchesBegan:touches withEvent:event];
    CGPoint location = [[[event allTouches] anyObject] locationInView:self.view];
    CGRect statusBarFrame = [UIApplication sharedApplication].statusBarFrame;

    if (CGRectContainsPoint(statusBarFrame, location)) {
        [UIView animateWithDuration:0.3f animations:^{
            self.tableView.contentOffset = CGPointMake(0, self.tableViewOriginalOffset);
            [self.tableView layoutIfNeeded];
        }];
    }
}
