后面经过测试,如果button的文字长度变更,会导致图片位置变化,经过多次修改UIEdgeInsets的值也没有达到期望效果,最终采用集成UIButton类,重写layoutSubviews函数实现,特将成果记录一下,以便后续查阅

-( void )layoutSubviews { [super layoutSubviews]; // Center image CGPoint center = self.imageView.center; center.x = self.frame.size.width/2; center.y = self.imageView.frame.size.height/2; self.imageView.center = center; //Center text CGRect newFrame = [self titleLabel].frame; newFrame.origin.x = 0; newFrame.origin.y = self.imageView.frame.size.height + 5; newFrame.size.width = self.frame.size.width; self.titleLabel.frame = newFrame; self.titleLabel.textAlignment = UITextAlignmentCenter; } |
通过重写,重新设置imageView的Center和titleLabel的Frame解决上述问题。
