MBProgressHUD提示框官网地址:https://github.com/jdg/MBProgressHUD
官网里已经提供了足够多的例子供我们使用,但在实现开发中,我们用到的只是其中的一小部分而已。为了使用更方便,下面对它进行扩展(Category)
MBProgressHUD+NJ.h
#import "MBProgressHUD.h" @interface MBProgressHUD (NJ) + (void)showSuccess:(NSString *)success;
+ (void)showSuccess:(NSString *)success toView:(UIView *)view; + (void)showError:(NSString *)error;
+ (void)showError:(NSString *)error toView:(UIView *)view; + (MBProgressHUD *)showMessage:(NSString *)message;
+ (MBProgressHUD *)showMessage:(NSString *)message toView:(UIView *)view; + (void)hideHUD;
+ (void)hideHUDForView:(UIView *)view; @end
MBProgressHUD+NJ.m
#import "MBProgressHUD+NJ.h" @implementation MBProgressHUD (NJ) /**
* 显示信息
*
* @param text 信息内容
* @param icon 图标
* @param view 显示的视图
*/
+ (void)show:(NSString *)text icon:(NSString *)icon view:(UIView *)view
{
if (view == nil) view = [[UIApplication sharedApplication].windows lastObject];
// 快速显示一个提示信息
MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:view animated:YES];
hud.labelText = text;
// 设置图片
hud.customView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[NSString stringWithFormat:@"MBProgressHUD.bundle/%@", icon]]];
// 再设置模式
hud.mode = MBProgressHUDModeCustomView; // 隐藏时候从父控件中移除
hud.removeFromSuperViewOnHide = YES; // 1秒之后再消失
[hud hide:YES afterDelay:0.7];
} /**

*/
+ (void)showSuccess:(NSString *)success
{
[self showSuccess:success toView:nil];
} /**

[self show:error icon:@"error.png" view:view];
} /**

*/
+ (MBProgressHUD *)showMessage:(NSString *)message
{
return [self showMessage:message toView:nil];
} /**

*
* @param message 信息内容
* @param view 需要显示信息的视图
*
* @return 直接返回一个MBProgressHUD,需要手动关闭
*/
+ (MBProgressHUD *)showMessage:(NSString *)message toView:(UIView *)view {
if (view == nil) view = [[UIApplication sharedApplication].windows lastObject];
// 快速显示一个提示信息
MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:view animated:YES];
hud.labelText = message;
// 隐藏时候从父控件中移除
hud.removeFromSuperViewOnHide = YES;
// YES代表需要蒙版效果
hud.dimBackground = YES;
return hud;
} /**
* 手动关闭MBProgressHUD
*/
+ (void)hideHUD
{
[self hideHUDForView:nil];
} /**
* 手动关闭MBProgressHUD
*
* @param view 显示MBProgressHUD的视图
*/
+ (void)hideHUDForView:(UIView *)view
{
if (view == nil) view = [[UIApplication sharedApplication].windows lastObject];
[self hideHUDForView:view animated:YES];
} @end
我们可以看到上面的代码,还引用了图标。直接把图标拷过去,最后的源码里有提供。项目结构:
使用方法很非常的简单。
弹框显示成功:
[MBProgressHUD showSuccess:@"测试showSuccess"];
弹框显示失败:
[MBProgressHUD showError:@"测试showError"];
弹框显示加载中:
[MBProgressHUD showMessage:@"正在加载数据中....."]; // 几秒后消失,当然,这里可以改为网络请求
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(5.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{ // 移除HUD
[MBProgressHUD hideHUD]; // 提醒有没有新数据
[MBProgressHUD showError:@"没有新数据"];
});
