现在很多APP的HUD已经都是自定义动画了，MBProgressHUD没有开放的API可以让我们直接使用，需要到.m文件中去修改源码。

首先在.m文件中找到

- (void)updateIndicators

方法在

if (mode == MBProgressHUDModeIndeterminate) {}

中自定义动画，然后上代码：

 

<span style="font-size:18px;">if (mode == MBProgressHUDModeIndeterminate) {
        if (!isActivityIndicator) {
            // Update to indeterminate indicator
            [indicator removeFromSuperview];
            self.indicator = MB_AUTORELEASE([[UIActivityIndicatorView alloc]
                                             initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]);
            self.indicator = MB_AUTORELEASE([[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 70, 40)]);
            self.indicator.contentMode = UIViewContentModeScaleAspectFit;
//          [(UIActivityIndicatorView *)indicator startAnimating];
            [self addSubview:indicator];

            for (int i=0; i<24; i++) {
                [_loadingArray addObject:[UIImage imageNamed:[NSString stringWithFormat:@"loading_%d",i + 1]]];
            }


            //设置动画数组
            [(UIImageView *)self.indicator setAnimationImages:_loadingArray];
            //设置动画播放次数
            [(UIImageView *)self.indicator setAnimationRepeatCount:MAXFLOAT];
            //设置动画播放时间
            [(UIImageView *)self.indicator setAnimationDuration:1.5];
            //开始动画
            [(UIImageView *)self.indicator startAnimating];
        }
#if __IPHONE_OS_VERSION_MIN_REQUIRED >= 50000
        if ([indicator isKindOfClass:[UIActivityIndicatorView class]]) {
            [(UIActivityIndicatorView *)indicator setColor:self.activityIndicatorColor];
        }

#endif
    }</span>

感兴趣的朋友可以尝试一下

 

 

回复hhhh23456789：我是把_loadingArray放在MB初始化方法里面声明的

- (id)initWithView:(UIView *)view {

NSAssert(view, @"View must not be nil.");

_loadingArray = [NSMutableArray array];

return [self initWithFrame:view.bounds];

}
