效果:
注意图里面了吗,其实那个效果做起来真的很简单,在iOS中苹果给我们封装的很好,关键是那个按钮
系统的按钮的图片是在左边的,这里我们需要把他调整到右边,然后呢需要我们自己做一下操作。
代码:
话不多说,先把所有代码放上来。能看懂就不用看别的了。(这么详细的注释,看不懂才怪。。)

{CGFloat imageY = 0;CGFloat imageH = contentRect.size.height;CGFloat imageW = 16;// 图片的X = 按钮的宽度 - 图片宽度CGFloat imageX = contentRect.size.width - imageW;return CGRectMake(imageX, imageY, imageW, imageH);
}@end
iOS6,7简单适配 文件: (Prefix.pch)
#define iOS7 ([[UIDevice currentDevice].systemVersion doubleValue] >= 7.0)
具体实现
把按钮图片放右边(自定义图片在右边的按钮)
要想实现自定义按钮位置 主要是重写下面两个方法
- (CGRect)titleRectForContentRect:(CGRect)contentRect;
- (CGRect)imageRectForContentRect:(CGRect)contentRect;
这里上面代码中写的很清楚了,不多说了就,需要注意的是,我们在算title的长度的时候出现了一些状况,那就是iOS6里面没有这个方法,以及xcode4.5版本会编译出错的问题,在这里做了iOS6,7的适配以及编译器的适配:
(iOS7)这个是宏,在pch文件里面有定义
#ifdef __IPHONE_7_0
是Availability.h里的 xcode4.5里面没有
#ifdef __IPHONE_7_0if (iOS7) { // 是IOS7CGRect titleRect = [title boundingRectWithSize:maxSize options:NSStringDrawingUsesLineFragmentOrigin attributes:md context:nil];titleW = titleRect.size.width;}else{// 非IOS7CGSize titleSize = [title sizeWithFont:self.myFont];titleW = titleSize.width;}
#else// XCODE4CGSize titleSize = [title sizeWithFont:self.myFont];titleW = titleSize.width;
#endif
具体如何重写的实现自定义图片在右边的button
看NYTitleButton.m(在上面)
弹出view
这个没啥好说的,就是开始定义一个view,然后设置hidden 看代码
懒加载contentView 并且在开始调用的适合(viewDidLoad)中设置隐藏。
/**懒加载,点击标题弹出的view*/
-(UIView *)contentView
{if (_contentView == nil) {// 添加将来需要显示的ViewUIView *contentView = [[UIView alloc] init];contentView.backgroundColor = [UIColor greenColor];contentView.frame = CGRectMake(0, 64, 320, 200);[self.view addSubview:contentView];_contentView = contentView;// 隐藏该View}return _contentView;
}- (void)viewDidLoad
{[super viewDidLoad];self.contentView.hidden = YES;
}
在点击按钮时候设置隐藏为no或yes,这里加了两个动画而已
- (IBAction)titleBtnOnClick:(NYTitleButton *)titleBtn {if (!self.isOpen) {// 没有打开[UIView animateWithDuration:1.0 animations:^{// 1.旋转按钮上的尖尖titleBtn.imageView.transform = CGAffineTransformMakeRotation(M_PI);}];// 改变当前按钮的状态CATransition *ca = [CATransition animation];ca.type = @"cube";[self.contentView.layer addAnimation:ca forKey:nil];self.open = YES;// 显示内容viewself.contentView.hidden = NO;}else // 已经打开{[UIView animateWithDuration:1.0 animations:^{// 1.旋转按钮上的尖尖titleBtn.imageView.transform = CGAffineTransformIdentity;}];// 改变当前按钮的状态//添加动画CATransition *ca = [CATransition animation];ca.type = @"cube";[self.contentView.layer addAnimation:ca forKey:nil];self.open = NO;// 隐藏内容Viewself.contentView.hidden = YES;}}
动画
这个搜easy,在前面有http://blog.csdn.net/u013357243/article/details/45583423
//添加动画CATransition *ca = [CATransition animation];ca.type = @"cube";[self.contentView.layer addAnimation:ca forKey:nil];
