一般来说，app里面的单纯的文本提示信息不会太长，一行肯定可以显示完全，所以用MBProgressHud在加上一个类扩展MBProgressHUD+Extension基本上都可以满足需求
MBProgressHUD+Extension.h .png这样子的类扩展可能很多人都见过，但是在最近的项目里面出现了由于要显示的提示信息过长，被省略，信息显示不全的情况，故添加了几个方法。专门用来显示文本信息，可以做到自适应文本大小。
MBProgressHUD+Extension.h .png 不多说，代码如下： .h +(void)showXYMessage:(NSString *)text; +(void)showXYMessage:(NSString *)text delay:(NSTimeInterval )time; +(void)showXYMessage:(NSString *)text toView:(UIView *)view; +(void)showXYMessage:(NSString *)text toView:(UIView *)view delay:(NSTimeInterval )time; @end.m
+(void)showXYMessage:(NSString *)text{ [self showXYMessage:text toView:nil delay:1.5f]; } +(void)showXYMessage:(NSString *)text delay:(NSTimeInterval )time{ [self showXYMessage:text toView:nil delay:time]; } +(void)showXYMessage:(NSString *)text toView:(UIView *)view delay:(NSTimeInterval )time{ if (view == nil) view = [[UIApplication sharedApplication].windows lastObject]; CGFloat width = view?view.bounds.size.width - 20:[UIScreen mainScreen].bounds.size.width- 2*30; CGFloat height = view?view.bounds.size.height - 20:[UIScreen mainScreen].bounds.size.width- 2*30; // 快速显示一个提示信息 MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:view animated:YES]; CGSize size = [text boundingRectWithSize:CGSizeMake(width, height) options:(NSStringDrawingUsesLineFragmentOrigin) attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:11]} context:nil].size;//修改字体大小（下面同步修改） UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, size.width<width?size.width:width, size.height)]; label.text = text; label.font = [UIFont systemFontOfSize:11];//修改字体大小（上面同步修改） label.textColor = [UIColor whiteColor];//修改字体颜色 label.numberOfLines = 0; label.textAlignment = NSTextAlignmentCenter; hud.customView = label; hud.mode = MBProgressHUDModeCustomView; [hud setUserInteractionEnabled:false]; // 隐藏时候从父控件中移除 hud.removeFromSuperViewOnHide = YES; // hud.square = true; hud.margin = 10.0f; // time秒之后再消失 [hud hideAnimated:YES afterDelay:time]; dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(time * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{ [self hideHUDForView:view]; }); } +(void)showXYMessage:(NSString *)text toView:(UIView *)view{ [self showXYMessage:text toView:view delay:1.5f]; } @end
