UILabelのheightやwidthを文字列の長さに合わせて調整する

Posted at

こんな感じで書くといけます!

Labelに表示したい文字列をmyObjectに、boldSystemFontOfSizeにフォントサイズを、maxWidthに最大のwidthを入れてあげるとCGSizeが取得できます。

CGSize textSize = [[myObject getALongText] 
                    sizeWithFont:[UIFont boldSystemFontOfSize:15] 
                    constrainedToSize:CGSizeMake(maxWidth, 2000)
                    lineBreakMode:UILineBreakModeWordWrap];
