需要獲取圖片的尺寸,高*寬。
然後將值傳遞到下面的代碼:
UIImageView *imgView=[[UIImageView alloc] initWithFrame:CGRectMake(25, 5, imgView.size.width, imgView.size.width)];
但是總是不成功,不知道應該怎麼實現?謝謝
UIImageView *imgView=[[UIImageView alloc] initWithFrame:CGRectMake(25, 5, imgView.size.width, imgView.size.width)];
你這樣創建,這時的UIImageView還沒有width及height.UIImageView 尺寸依據它添加的UIImage
UIImage *img=[UIImage imageNamed:@""];
UIImageView *imgView=[[UIImageView alloc] initWithImage:img];
imgView.frame=CGRectMake(25, 5, imgView.size.width, imgView.size.width);
