基于IOS实现带箭头的view

#pragma mark -


- (void)startAnimateView_x:(CGFloat) x
_y:(CGFloat) y
origin_width:(CGFloat) width
origin_height:(CGFloat) height
{
[UIView animateWithDuration:0.25 animations:^{
self.backGoundView.frame = CGRectMake(x, y, width, height);
}completion:^(BOOL finished) {
NSArray *results = [self.backGoundView subviews];
for (UIView *view in results) {
[view setHidden:NO];
}
}];
}

点击空白处回收


#pragma mark -
- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
if (![[touches anyObject].view isEqual:self.backGoundView]) {
[self dismiss];
} 
}

#pragma mark -
- (void)dismiss
{
/**
* 删除 在backGroundView 上的子控件
*/
NSArray *results = [self.backGoundView subviews];
for (UIView *view in results) {
[view removeFromSuperview]; 
}
[UIView animateWithDuration:0.25 animations:^{
//
self.backGoundView.frame = CGRectMake(self.origin.x, self.origin.y, 0, 0);
} completion:^(BOOL finished) {
//
[self removeFromSuperview];
}];
}

内部的tableview


#pragma mark -
- (UITableView *)tableView
{
if (!_tableView) {
_tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, self.backGoundView.frame.size.width - 5, self.backGoundView.frame.size.height) style:UITableViewStylePlain];
_tableView.dataSource = self;
_tableView.backgroundColor = [UIColor clearColor];
_tableView.delegate = self;
}
return _tableView;
}
#pragma mark -
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return self.dataArray.count;
}
#pragma mark -
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (self.row_height == 0) {
return 44;
}else{
return self.row_height;
}
}
#pragma mark -
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

static NSString *cellIdentifier = @"cellIdentifier2";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier];
}
cell.backgroundColor = [UIColor clearColor];
cell.imageView.image = [UIImage imageNamed:self.images[indexPath.row]];
cell.textLabel.text = self.dataArray[indexPath.row];
cell.textLabel.font = [UIFont systemFontOfSize:self.fontSize];
cell.textLabel.textColor = self.titleTextColor;
return cell;
}
// 想要实现点击进行其他操作, 这里用到了协议
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (self.delegate && [self.delegate respondsToSelector:@selector(selectIndexPathRow:)]) {
[self.delegate selectIndexPathRow:indexPath.row];
}
}

##在.h文件还要声明一份协议


@protocol selectIndexPathDelegate <NSObject>
- (void)selectIndexPathRow:(NSInteger )index;
@end
