自己自定义了一些最常用的控件，效果如下。这些控件是非常简单的，但是在一般开发过程中，很多人都比较喜欢直接拉一个第三方来实现。（如在做加载控件时都喜欢使用MBProgressHUD库），不曾想就为了这一个小小的控件把人家的整份代码都copy过来。对于追求能自己写就尽量自己写的我来说，起码在使用加载控件时，我是不能忍受的。所以简简单单封装了一套：
代码如下：
.h中的代码：
// // HKUIToolsView.h // HKUIToolsDemo // // Created by isHakan on 2017/7/28. // Copyright © 2017年 liuhuakun.

.m中的代码：

在需要调用对应控件的界面处，
// // ViewController.m // HKUIToolsDemo // // Created by isHakan on 2017/7/28. // Copyright © 2017年 liuhuakun. All rights reserved. // #import "ViewController.h"#import "HKUIToolsView.h"@interface ViewController ()@end@implementation ViewController- (void)viewDidLoad {[super viewDidLoad];// Do any additional setup after loading the view, typically from a nib. }- (IBAction)centerPointViewShowBtnClick:(UIButton *)sender {[self showToolMsg:@"中心提示信息显示！" viewTag:sender.tag]; }- (IBAction)loadViewShow:(UIButton *)sender {[self showToolMsg:@"加载中..." viewTag:sender.tag]; }- (IBAction)bottomPointViewShow:(UIButton *)sender {[self showToolMsg:@"底部提示信息提示！" viewTag:sender.tag]; }- (void)showToolMsg:(NSString *)msg viewTag:(NSInteger)viewTag {HKUIToolsView *toolsView = [[HKUIToolsView alloc] initWithFrame:[UIScreen mainScreen].bounds withMsg:msg andType:viewTag];toolsView.tag = 222;[[UIApplication sharedApplication].keyWindow addSubview:toolsView]; }- (void)didReceiveMemoryWarning {[super didReceiveMemoryWarning];// Dispose of any resources that can be recreated. }@end
