前语：很多时候需要用到一个小弹窗进行信息的中心展现，或者在底部需要弹出一个弹窗进行二次承认，在寻觅过程中发现一个第三方库KLCPopup，运用起来非常方便，能够自定义弹窗视图，能够在屏幕的不同方位、不同方向、不同动效的方法进行弹出和消失，这里简略说一说运用方法吧。

github原地址：KLCPopup

引入Podfile

引入项目

在终端中cd到项目目录下，进行pod install将KLCPopup引入项目

创立Popup
/// 默认创立Popup方法
+ (KLCPopup*)popupWithContentView:(UIView*)contentView;
/// 创立自定义Popup方法
/// - Parameters:
///   - contentView: 弹窗View
///   - showType: 展现方法
///   - dismissType: 消失方法
///   - maskType: 弹窗背后蒙层款式
///   - shouldDismissOnBackgroundTouch: 点击布景蒙层弹窗是否消失
///   - shouldDismissOnContentTouch: 点击弹窗视图弹窗是否消失
+ (KLCPopup*)popupWithContentView:(UIView*)contentView
						 showType:(KLCPopupShowType)showType
					  dismissType:(KLCPopupDismissType)dismissType
						 maskType:(KLCPopupMaskType)maskType
		 dismissOnBackgroundTouch:(BOOL)shouldDismissOnBackgroundTouch

建议运用自定义Popup创立方法，这样能够更加方便的创立出满意需求的弹窗，包括展现、消失方法以及交互方法等需求。

设置Popup弹窗展现（方位、时刻）
/// 弹窗呈现（假如没有设置Layout则展现在屏幕中心）
- (void)show {
  [self showWithLayout:KLCPopupLayoutCenter];
}
/// 设置弹窗Layout
- (void)showWithLayout:(KLCPopupLayout)layout {
  [self showWithLayout:layout duration:0.0];
}
/// 设置弹窗展现时刻
- (void)showWithDuration:(NSTimeInterval)duration {
  [self showWithLayout:KLCPopupLayoutCenter duration:duration];
}
/// 设置弹窗Layout和展现时刻
- (void)showWithLayout:(KLCPopupLayout)layout duration:(NSTimeInterval)duration {
  NSDictionary* parameters = @{@"layout" : [NSValue valueWithKLCPopupLayout:layout],
                               @"duration" : @(duration)};
  [self showWithParameters:parameters];
}
/// 设置弹窗的中心点，在view视图上的方位
- (void)showAtCenter:(CGPoint)center inView:(UIView*)view {
  [self showAtCenter:center inView:view withDuration:0.0];
}
/// 设置弹窗的中心点，在view视图上的方位和展现时刻
- (void)showAtCenter:(CGPoint)center inView:(UIView *)view withDuration:(NSTimeInterval)duration {
  NSMutableDictionary* parameters = [NSMutableDictionary dictionary];
  [parameters setValue:[NSValue valueWithCGPoint:center] forKey:@"center"];
  [parameters setValue:@(duration) forKey:@"duration"];
  [parameters setValue:view forKey:@"view"];
  [self showWithParameters:[NSDictionary dictionaryWithDictionary:parameters]];
}

建议运用showWithLayout方法来修正弹窗展现方位

Popup运用实例 

- (void)clickAlertAction {
CommonAlertView *alertView = [[CommonAlertView alloc] initWithFrame:CGRectMake(0, 0, Common.screenWidth, ([@130 fit] + Common.safeAreaBottom)) withContent:@"承认支付订单？"];
KLCPopup *popup = [KLCPopup popupWithContentView:alertView showType:KLCPopupShowTypeSlideInFromBottom dismissType:KLCPopupDismissTypeSlideOutToBottom maskType:KLCPopupMaskTypeDimmed dismissOnBackgroundTouch:YES dismissOnContentTouch:NO];
[popup showWithLayout:KLCPopupLayoutMake(KLCPopupHorizontalLayoutCenter, KLCPopupVerticalLayoutBottom)];
/// 点击撤销按钮
alertView.cancelButtonAction = ^{
	///	弹窗消失
    [popup dismiss:YES];
};
/// 点击承认按钮
alertView.confirmButtonAction = ^{
	///	弹窗消失
    [popup dismiss:YES];
    /// 履行自定义操作
    /// xxxx

[popup show];
}
