dispatch_group_enter/dispatch_group_leave is your App code, not SDWebImage's code

You can not (currently) assume each sd_setImage call must always callback. So the enter and leave may not get balanced. I guess this is a bug, but need more info to investigate

这个错误我也捕捉不到,我也是根据崩溃反馈,所拿到的崩溃在sebwebimg里面了,求大佬指点

If dispatch_group_enter/dispatch_group_leave cannot be used, how to achieve similar requirements?
