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   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 -(void)layoutSubviews {     [super layoutSubviews];       // Center image     CGPoint c…

经查阅资料及尝试,最终解决了在图片和文字垂直排列的情况下,如果文字长度变化会导致图片位置变动的问题,最开始采用了网上比较多的做法,做法如下: @interface UIButton (UIButtonExt)   - (void)centerImageAndTitle:(float)space;   - (void)centerImageAndTitle;   @end   @implementation UIButton (UIButtonExt)   - (void)centerImageA…

#pragma mark 按钮图片文字垂直居中排列 -(void)setButtonContentCenter:(UIButton *)button { CGSize imgViewSize,titleSize,btnSize; UIEdgeInsets imageViewEdge,titleEdge; CGFloat heightSpace = 10.0f; //设置按钮内边距 imgViewSize = button.imageView.bounds.size; titleSize = bu…

UIImage *image2 = [UIImage imageNamed:imgName]; CGFloat top = ; // 顶端盖高度 CGFloat bottom = ; // 底端盖高度 CGFloat left = ; // 左端盖宽度 CGFloat right = ; // 右端盖宽度 UIEdgeInsets insets = UIEdgeInsetsMake(top, left, bottom, right); image2 = [image2 resizableImag…

[btn.imageView setContentMode:UIViewContentModeScaleAspectFill];…

一,设置单选效果 - (void)selectedBtnPress:(UIButton*)sender { //首先把原来按钮的选中效果消除 for (int i=0;i<num;i++) {//num为总共设置单选效果按钮的数目 UIButton *btn = (UIButton*)[view viewWithTag:i];//view为这些btn的父视图 btn.selected = NO; } sender.selected = YES;//sender.selected = !sende…

UIButton同时设置Title和Image后,默认是图片在左文字在右,如下图1,很多情况下我们希望图片在上图片在下,如下图2,只需要简单的几行代码,即可实现. (1)因为需要处理多个按钮,所以将实现代码封装为一个方法,把每个UIbutton实例作为参数传入即可,代码如下:   -(void)initButton:(UIButton*)btn{ btn.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;…

创建button设置可以折行显示 - (void)viewDidLoad { [super viewDidLoad]; UIButton * button = [[UIButton alloc] initWithFrame:CGRectMake(20, 30, 150, 70)]; [self.view addSubview:button]; [button setTitle:@"button" forState:UIControlStateNormal]; [button setTi…

一,通过按钮的事件来设置背景色 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 - (void)viewDidLoad {     [super viewDidLoad];           UIButton *button1 = [[UIButton alloc] initWithFrame:CGRectMake(50, 200, 100, 50)];     [button1 setTitle:@"button1"…

首先在控制器中创建一个button - (void)viewDidLoad { [super viewDidLoad]; UIButton * button = [[UIButton alloc] initWithFrame:CGRectMake(20, 30, 35, 50)]; [self.view addSubview:button]; [button setTitle:@"button" forState:UIControlStateNormal]; [button setTi…
