我正在寻找iPhone中的弹出窗口,我想让它像iOS 5阅读器功能:

经过很少的研究,我找到了WEPopover和FPPopover,但我正在寻找是否有像这个内置的iphone SDK这样的API。

你可以用一些自定义的图片制作一个UIView,并在视图顶部显示一个动画,作为一个"popover“,带有如下按钮:
UIView *customView = [[UIView alloc] initWithFrame:CGRectMake(25, 25, 100, 50)]; //<- change to where you want it to show.
//Set the customView properties
customView.alpha = 0.0;
customView.layer.cornerRadius = 5;
customView.layer.borderWidth = 1.5f;
customView.layer.masksToBounds = YES;
//Add the customView to the current view
[self.view addSubview:customView];
//Display the customView with animation
[UIView animateWithDuration:0.4 animations:^{
[customView setAlpha:1.0];
} completion:^(BOOL finished) {}];如果你想使用customView.layer,别忘了使用#import <QuartzCore/QuartzCore.h>。

由于我们现在可以在iOS8上创建弹出窗口,这在iPhone上和在iPad上是一样的,对于那些开发通用应用程序的人来说,这将是特别棒的,因此不需要单独创建视图或代码。
您可以在此处获得类和演示项目:https://github.com/soberman/ARSPopover
您所需要做的就是将UIViewController子类,符合UIPopoverPresentationControllerDelegate协议,并设置所需的modalPresentationStyle和delegate值:
// This is your CustomPopoverController.m
@interface CustomPopoverController () <UIPopoverPresentationControllerDelegate>
@end
@implementation CustomPopoverController.m
- (instancetype)init {
if (self = [super init]) {
self.modalPresentationStyle = UIModalPresentationPopover;
self.popoverPresentationController.delegate = self;
}
return self;
}
- (UIModalPresentationStyle)adaptivePresentationStyleForPresentationController:(UIPresentationController *)controller {
return UIModalPresentationNone; //You have to specify this particular value in order to make it work on iPhone.
}然后,用要显示它的方法实例化新创建的子类,并将另外两个值分配给sourceView和sourceRect。它看起来是这样的:
CustomPopoverController *popoverController = [[CustomPopoverController alloc] init];
popoverController.popoverPresentationController.sourceView = sourceView; //The view containing the anchor rectangle for the popover.
popoverController.popoverPresentationController.sourceRect = CGRectMake(384, 40, 0, 0); //The rectangle in the specified view in which to anchor the popover.
[self presentViewController:popoverController animated:YES completion:nil];现在你看到了,漂亮的,整齐的模糊的popover。
