在这我直接介绍需要添加哪些代码，可直接复制黏贴来使用。我是特意创建的 Tool.h Tool.m 来放oc代码公用的方法，要是放在.swift就不用这么麻烦了可以直接使用。

1. 在 Tool.h 文件中添加如下代码：

//类似安卓提示框

+(void)showMessage:(NSString *)message withFont:(CGFloat)font;

2.在 Tool.m 文件中添加如下代码:

#pragma mark -- 提示框

+(void)showMessage:(NSString *)message withFont:(CGFloat)font

{

// UIWindow * window = [UIApplication sharedApplication].keyWindow;

UIWindow * window = [[UIApplicationsharedApplication].windowsobjectAtIndex:1];

UIView *showview = [[UIViewalloc]init];

showview.backgroundColor = [UIColorblackColor];

showview.frame =CGRectMake(1,1, 1,1);

showview.alpha =1.0f;

showview.layer.cornerRadius =5.0f;

showview.layer.masksToBounds =YES;

[window addSubview:showview];

[window bringSubviewToFront:showview];

UILabel *label = [[UILabelalloc]init];

CGSize LabelSize = [messagesizeWithFont:[UIFontsystemFontOfSize:font+2]constrainedToSize:CGSizeMake(290,9000)];

label.frame =CGRectMake(10,5, LabelSize.width, LabelSize.height);

label.text = message;

label.textColor = [UIColorwhiteColor];

label.textAlignment =1;

label.backgroundColor = [UIColorclearColor];

// label.font = [UIFont boldSystemFontOfSize:font];//需要使用加粗字体文字可打开这行，注释

label.font = [UIFontsystemFontOfSize:font];

[showview addSubview:label];

showview.frame =CGRectMake(([UIScreenmainScreen].bounds.size.width - LabelSize.width - 20)/2, [UIScreenmainScreen].bounds.size.height - 100, LabelSize.width+20, LabelSize.height+10);

[UIViewanimateWithDuration:2animations:^{

showview.alpha =0;

} completion:^(BOOL finished) {

[showview removeFromSuperview];

}];

}

3.在别的viewcontroller.swift 调用的代码如下：

Tool.showMessage("输入你想要显示的文字！", withFont: 15)
