First, Uiimageview

1. When the picture is set to a circle, it may be displayed as a result of the picture's wide and high proportions.

FIX: Set Uiimageview contentmode to Uiviewcontentmodescaleaspectfill

Contentmode Property

typedef ns_enum (Nsinteger, Uiviewcontentmode) {Uiviewcontentmodescaletofill, Uiviewcontentmodescaleaspectfit, //contents scaled to fit with fixed aspect. Remainder is transparentUiviewcontentmodescaleaspectfill,//contents scaled to fill with fixed aspect. Some portion of content may be clipped.Uiviewcontentmoderedraw,//Redraw on Bounds change (calls-setneedsdisplay)Uiviewcontentmodecenter,//contents remain same size. positioned adjusted.uiviewcontentmodetop, Uiviewcontentmodebottom, Uiviewcontentmodeleft, Uiviewcontentmoderight, UIViewCo Ntentmodetopleft, Uiviewcontentmodetopright, Uiviewcontentmodebottomleft, Uiviewcontentmodebottomright,};

Uiviewcontentmodescaletofill Scaling to fill

Uiviewcontentmodescaleaspectfit zoom to show all, scale unchanged
