今天给大家分享3种提示三方。SVProgressHUD，JFMinimalNotification，UIView+Toast
SVProgressHUD
pod 'SVProgressHUD'
// 位置 偏移
// [SVProgressHUD setOffsetFromCenter:UIOffsetMake(0, 100)];
//要显示的内容
//显示文字
[SVProgressHUD showWithStatus:@"努力加载中"];
// //进度
// [SVProgressHUD showProgress:.2 status:@"进度"];
// //感叹号
// [SVProgressHUD showInfoWithStatus:@"感叹号"];
// //success
// [SVProgressHUD showSuccessWithStatus:@"Success!"];
// //error
// [SVProgressHUD showErrorWithStatus:@"Error"];
// 整个后面的背景选择
[SVProgressHUD setDefaultMaskType:SVProgressHUDMaskTypeNone];
// 转圈的宽度(有文本)
[SVProgressHUD setRingThickness:3];
//无文本时设置圈宽
//[SVProgressHUD setRingNoTextRadius:3];
//无边框背景样式
[SVProgressHUD setDefaultStyle:SVProgressHUDStyleCustom];
// SVProgressHUDStyleLight 白底黑字
// SVProgressHUDStyleDark 黑底白字
//框颜色
[SVProgressHUD setBackgroundColor:[UIColor yellowColor]];
//字体和圈的颜色
[SVProgressHUD setForegroundColor:[UIColor redColor]];
JFMinimalNotification
显示在顶部
pod 'JFMinimalNotifications'
#import "ViewController.h"
#import "JFMinimalNotification.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
[self displaySuccess:@"成功"];
}
#pragma mark - JFMinimalNotification
static NSInteger const afterTime = 4.0;
- (void)displaySuccess:(NSString *)title
{
JFMinimalNotification *minimalNotification = [JFMinimalNotification notificationWithStyle:JFMinimalNotificationStyleSuccess
title:@"完成"
subTitle:title
dismissalDelay:afterTime touchHandler:^{
}];
[self.view addSubview:minimalNotification];
minimalNotification.presentFromTop = YES;
[minimalNotification show];
}
- (void)displayError:(NSString *)title
{
JFMinimalNotification *minimalNotification = [JFMinimalNotification notificationWithStyle:JFMinimalNotificationStyleError
title:@"错误"
subTitle:title
dismissalDelay:afterTime touchHandler:^{
}];
[self.view addSubview:minimalNotification];
minimalNotification.presentFromTop = YES;
[minimalNotification show];
}
- (void)displayWarning:(NSString *)title
{
JFMinimalNotification *minimalNotification = [JFMinimalNotification notificationWithStyle:JFMinimalNotificationStyleWarning
title:@"警告"
subTitle:title
dismissalDelay:afterTime touchHandler:^{
}];
[self.view addSubview:minimalNotification];
minimalNotification.presentFromTop = YES;
[minimalNotification show];
}
UIView+Toast
文字、图片（视图显示在屏幕底部）
// each makeToast method creates a view and displays it as toast
//提示文字
- (void)makeToast:(NSString *)message;
//持续interval秒的提示文字
- (void)makeToast:(NSString *)message duration:(CGFloat)interval position:(id)position;
//持续interval秒的多段文字
- (void)makeToast:(NSString *)message duration:(CGFloat)interval position:(id)position title:(NSString *)title;
//带有图片的持续interval秒的多段文字
- (void)makeToast:(NSString *)message duration:(CGFloat)interval position:(id)position title:(NSString *)title image:(UIImage *)image;
//带有图片的持续interval秒的1段文字
- (void)makeToast:(NSString *)message duration:(CGFloat)interval position:(id)position image:(UIImage *)image;
菊花（显示在屏幕中间）
// displays toast with an activity spinner
- (void)makeToastActivity;
- (void)makeToastActivity:(id)position;
- (void)hideToastActivity;
UIView+Toast源码如下
UIView+Toast.h
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
@interface UIView (Toast)
// each makeToast method creates a view and displays it as toast
- (void)makeToast:(NSString *)message;
- (void)makeToast:(NSString *)message duration:(CGFloat)interval position:(id)position;
- (void)makeToast:(NSString *)message duration:(CGFloat)interval position:(id)position title:(NSString *)title;
- (void)makeToast:(NSString *)message duration:(CGFloat)interval position:(id)position title:(NSString *)title image:(UIImage *)image;
- (void)makeToast:(NSString *)message duration:(CGFloat)interval position:(id)position image:(UIImage *)image;
// displays toast with an activity spinner
- (void)makeToastActivity;
- (void)makeToastActivity:(id)position;
- (void)hideToastActivity;
// the showToast methods display any view as toast
- (void)showToast:(UIView *)toast;
- (void)showToast:(UIView *)toast duration:(CGFloat)interval position:(id)point;
