模仿微信底部ActionSheet, 支持横屏显示.(支持iOS6及往后版本)
按钮如果过多则默认显示为屏幕高度的默认比例, 然后按钮支持滑动, 否则不支持滑动按钮.
几种效果样式如图:
```Objective-C // 类UIActionSheet初始化绑定代理和设置标题 - (void)show { FSActionSheet *actionSheet = [[FSActionSheet alloc] initWithTitle:@"这是ActionSheet的标题" delegate:self cancelButtonTitle:@"关闭" highlightedButtonTitle:@"删除" otherButtonTitles:@[@"拍照", @"从相册选取"]]; // show [actionSheet show]; } // FSActionSheetDelegate - (void)FSActionSheet:(FSActionSheet *)actionSheet selectedIndex:(NSInteger)selectedIndex { NSLog(@"选择了第[%zi]项", selectedIndex); }
// 自己组装item设定为actionSheet的按钮
- (void)show { NSMutableArray *actionSheetItems = [@[FSActionSheetTitleWithImageItemMake(FSActionSheetTypeNormal, [UIImage imageNamed:@"camera"], @"拍照"), FSActionSheetTitleWithImageItemMake(FSActionSheetTypeNormal, [UIImage imageNamed:@"album"], @"从相册选取"), FSActionSheetTitleWithImageItemMake(FSActionSheetTypeHighlighted, [UIImage imageNamed:@"delete"], @"删除")] mutableCopy]; FSActionSheet *actionSheet = [[FSActionSheet alloc] initWithTitle:nil cancelTitle:@"关闭" items:actionSheetItems]; actionSheet.contentAlignment = FSContentAlignmentLeft; // 展示并绑定选择回调 [actionSheet showWithSelectedCompletion:^(NSInteger selectedIndex) { FSActionSheetItem *item = actionSheetItems[selectedIndex]; _label.text = item.title; }]; }
