iOS Button 上文字图片位置的设置
- 1. 添加图片+文字／文字+图片 ，不分前后，图片默认在文字前边 加空格隔开
UIButton * button =[[UIButton alloc] initWithFrame:CGRectMake(30, 200, 300, 50)]; button.backgroundColor =[UIColor grayColor]; //图片 [button setImage:[UIImage imageNamed:@"but"] forState:UIControlStateNormal]; //文字 [button setTitle:@" But文字" forState:UIControlStateNormal]; [button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; button.titleLabel.font =[UIFont boldSystemFontOfSize:40]; [self.view addSubview:button];
- 2.设置文字图片 显示整体位置：居中、左、右； 单独设置文字的位置
- top : 为正数的时候,是往下偏移,为负数的时候往上偏移;
- left : 为正数的时候往右偏移,为负数的时候往左偏移;
- bottom : 为正数的时候往上偏移,为负数的时候往下偏移;
- right :为正数的时候往左偏移,为负数的时候往右偏移;
UIButton * button =[[UIButton alloc] initWithFrame:CGRectMake(30, 200, 300, 50)]; button.backgroundColor =[UIColor grayColor]; //文字 [button setTitle:@"But文字" forState:UIControlStateNormal]; [button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; button.titleLabel.font =[UIFont boldSystemFontOfSize:40]; //图片 [button setImage:[UIImage imageNamed:@"but"] forState:UIControlStateNormal]; /////////////修改/////////////////// button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;//使图片和文字水平居中显示 /* UIControlContentHorizontalAlignmentCente UIControlContentHorizontalAlignmentLeft UIControlContentHorizontalAlignmentRight UIControlContentHorizontalAlignmentFill */ //文字 可以显示在 button 视图之外，但不接收点击事件响应 [button setTitleEdgeInsets:UIEdgeInsetsMake(button.imageView.frame.size.height ,button.imageView.frame.size.width, 0.0,0.0)];//文字距离上边框的距离增加imageView的高度，距离左边框减少imageView的宽度，距离下边框和右边框距离不变 /////////////////////////////////////// [self.view addSubview:button];
3.效果：
UIButton * button =[[UIButton alloc] initWithFrame:CGRectMake(30, 200, 300, 50)]; button.backgroundColor =[UIColor grayColor]; //文字 [button setTitle:@"But文字" forState:UIControlStateNormal]; [button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; button.titleLabel.font =[UIFont boldSystemFontOfSize:40]; //图片 [button setImage:[UIImage imageNamed:@"xia"] forState:UIControlStateNormal]; /////////////修改/////////////////// button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft; button.imageEdgeInsets = UIEdgeInsetsMake(0,300-50, 0, 0); //上左下右
//button.titleEdgeInsets = UIEdgeInsetsMake(0,300-50, 0, 0); // 设置文字的位置 上左下右
/////////////////////////////////////// [self.view addSubview:button];
4/ 但是图片尺寸大了 位置会错乱， 如有遇到的请评论指点
