自定义提示框

1.  首先导入MBProgressHUD类

2. //自定义提示框

- (void)showAllTextDialog:(NSString *)str

{

    MBProgressHUD *hud = [[MBProgressHUD alloc] initWithView:self.view];

    [[[[UIApplication sharedApplication] delegate] window] addSubview:hud];

    hud.labelText = str;

    hud.mode = MBProgressHUDModeText;

    [hud showAnimated:YES whileExecutingBlock:^{

        sleep(1);

    } completionBlock:^{

        [hud removeFromSuperview];

    }];

}

3.  所需之处调用该方法。。。

/////

或者。。。

//自定义提示框

+ (void)showAllTextDialog:(NSString *)str

{

    MBProgressHUD *hud = [[MBProgressHUD alloc] initWithView:[UIApplication sharedApplication].keyWindow];

    [[[[UIApplication sharedApplication] delegate] window] addSubview:hud];

    hud.labelText = str;

    hud.mode = MBProgressHUDModeText;

    hud.yOffset = 250.0f;

    [hud showAnimated:YES whileExecutingBlock:^{

        sleep(1);

    } completionBlock:^{

        [hud removeFromSuperview];

    }];

}
