下拉刷新一直都是第三库的天下,有的第三库甚至支持上下左右刷新,UIRefreshControl是iOS6之后支持的一个刷新控件,不过由于功能单一,样式不能自定义,因此不能满足大众的需求,用法比较简单在UITableview和UICollectionview上面直接添加子视图即可使用。
代码调用:
1
2
3
4
5
6
7
|
self
.refreshControl = [[UIRefreshControl alloc] init];
[_refreshControl addTarget:
self
action:
@selector
(refreshView:)
forControlEvents:UIControlEventValueChanged];
[
self
.refreshControl setAttributedTitle:[[
NSAttributedString
alloc] initWithString:@
"数据加载-FlyElephant"
]];
[
self
.refreshControl setTintColor:[UIColor redColor]];
[
self
.tableView addSubview:
self
.refreshControl];
|
刷新回调:
1
2
3
4
5
6
|
-(
void
)refreshView:(UIRefreshControl *)control{
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3.0 *
NSEC_PER_SEC
)), dispatch_get_main_queue(), ^{
[
self
.refreshControl endRefreshing];
NSLog
(@

);
});
}
|
当然如果有合适的图片我们可以覆盖加载的图片:
1
2
3
4
|
self
.loadingImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed: @
"RefreshIcon"
]];
self
.loadingImageView.center = CGPointMake(CGRectGetMidX(
self
.view.bounds), 30);
[
self
.refreshControl insertSubview:
self
.loadingImageView atIndex:0];
[
self
.refreshControl bringSubviewToFront:
self
.loadingImageView];
|
实现效果不是很好:
