一般來說，app里面的單純的文本提示信息不會(huì)太長(zhǎng)，一行肯定可以顯示完全，所以用MBProgressHud在加上一個(gè)類擴(kuò)展MBProgressHUD+Extension基本上都可以滿足需求

這樣子的類擴(kuò)展可能很多人都見過，但是在最近的項(xiàng)目里面出現(xiàn)了由于要顯示的提示信息過長(zhǎng)，被省略，信息顯示不全的情況，故添加了幾個(gè)方法。專門用來顯示文本信息，可以做到自適應(yīng)文本大小。

不多說，代碼如下：
.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;
// 快速顯示一個(gè)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;//修改字體大?。ㄏ旅嫱叫薷模?
UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, size.width<width?size.width:width, size.height)];
label.text = text;
label.font = [UIFont systemFontOfSize:11];//修改字體大?。ㄉ厦嫱叫薷模? label.textColor = [UIColor whiteColor];//修改字體顏色
label.numberOfLines = 0;
label.textAlignment = NSTextAlignmentCenter;
hud.customView = label;
hud.mode = MBProgressHUDModeCustomView;
[hud setUserInteractionEnabled:false];
// 隱藏時(shí)候從父控件中移除
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
