iOS开发自定义SC_ProgressHUD动画加载页面

SC_ProgressHUD.h

#import <UIKit/UIKit.h>

@interface SC_ProgressHUD : UIView
//背景View
@property(nonatomic, strong)UIView *SC_backView;
//动图的imageView
@property(nonatomic, strong)UIImageView *SC_imageView;
//文字描述的label
@property(nonatomic, strong)UILabel *SC_label;
//存放动画的数组
@property(nonatomic, strong)NSMutableArray *SC_imageArray;

ViewController.h（使用自定义封装的类）

#import "SC_ProgressHUD.h"
@interface ViewController ()
@property(nonatomic, strong)SC_ProgressHUD *progressHUD;
@end
@implementation ViewController
- (void)viewDidLoad {
   //初始化_progressHUD，并添加_progressHUD
     _progressHUD = [[SC_ProgressHUD alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
     _progressHUD.backgroundColor = [UIColor colorWithRed:0.89 green:0.89 blue:0.9 alpha:1];
     _progressHUD.SC_label.text = @"Waiting...";
     _progressHUD.SC_label.textColor  = [UIColor grayColor];
     [self.view addSubview:_progressHUD];

     //数据加载完成之后移除_progressHUD
    //[_progressHUD removeFromSuperview];
