在任意UIView上显示Badge（兼容IOS6）
之前写过一篇文章在任意UIView上显示Badge，但IOS6上失败了，原来是苹果将Badge的类名改了，所以这里作下兼容，源码如下：
- (UIView *)showBadgeValue:(NSString *)strBadgeValue{ UITabBar *tabBar = [[UITabBar alloc] initWithFrame:CGRectMake(0, 0, 320, 50)]; UITabBarItem *item = [[UITabBarItem alloc] initWithTitle:@"" image:nil tag:0]; item.badgeValue = strBadgeValue; NSArray *array = [[NSArray alloc] initWithObjects:item, nil]; tabBar.items = array; [item release]; [array release]; //寻找 for (UIView *viewTab in tabBar.subviews) { for (UIView *subview in viewTab.subviews) { NSString *strClassName = [NSString stringWithUTF8String:object_getClassName(subview)]; if ([strClassName isEqualToString:@"UITabBarButtonBadge"] || [strClassName isEqualToString:@"_UIBadgeView"]) { //从原视图上移除 [subview removeFromSuperview]; // [self addSubview:subview]; subview.frame = CGRectMake(self.frame.size.width-subview.frame.size.width, 0, subview.frame.size.width, subview.frame.size.height); [tabBar release]; return subview; } } } [tabBar release]; return nil;}- (void)removeBadgeValue{ // for (UIView *subview in self.subviews) { NSString *strClassName = [NSString stringWithUTF8String:object_getClassName(subview)]; if ([strClassName isEqualToString:@"UITabBarButtonBadge"] || [strClassName isEqualToString:@"_UIBadgeView"]) { [subview removeFromSuperview]; break; } }}
