UIButton *button = [[UIButton alloc]initWithFrame:CGRectMake(110, 100, 100, 30)];

button.backgroundColor = [UIColor redColor];

button.titleLabel.font = [UIFont systemFontOfSize:19.0];//设置按钮的文字大小

button.contentHorizontalAlignment =UIControlContentHorizontalAlignmentLeft;//设置按钮文字的位置（默认为居中）

button.contentEdgeInsets = UIEdgeInsetsMake(0, 20, 0, 0);//字体靠左或右时与边缘的距离

[button setTitleColor:[UIColor yellowColor] forState:UIControlStateNormal];//设置按钮文字的颜色

[button setTitle:@"LYD" forState:UIControlStateNormal];

[self.window addSubview:button];

[button release];

  //第二种创建按钮的方法

//buttonWithType

UIButton *button1 = [UIButton buttonWithType:UIButtonTypeCustom];

button1.layer.cornerRadius = 10.0;

//UIButtonTypeInfoLight 微件(widget)使用的蓝色小圆圈信息按钮，可以放在任何文字旁边

//UIButtonTypeRoundedRect 圆角矩形

//UIButtonTypeInfoDark  白色背景下使用的深色圆圈信息按钮

//UIButtonTypeContactAdd 圆圈中一个加号的信息按钮

CGRect RECT = CGRectMake(110, 100, 30, 30);

/*//button1.selected = YES;

//button1.enabled = NO;

//设置标题，状态正常

[button1 setTitle:@"normal" forState:UIControlStateNormal];

//设置标题，状态高亮

[button1 setTitle:@"highlighted" forState:UIControlStateHighlighted];

//设置标题，状态禁用

[button1 setTitle:@"disabled" forState:UIControlStateDisabled];

//设置标题，状态选中

[button1 setTitle:@"selected" forState:UIControlStateSelected];*/

//设置背景图片

[button1 setBackgroundImage:[UIImage imageNamed:@"button_white"] forState:UIControlStateNormal];

[button1 setBackgroundImage:[UIImage imageNamed:@"button_red"] forState:UIControlStateSelected];

//    [button1 setImage:[UIImage imageNamed:@"button_red"] forState:UIControlStateSelected];

//添加事件

//用户控件之内触摸抬按下时

[button1 addTarget:self action:@selector(touchInSide:) forControlEvents:UIControlEventTouchUpInside];

//当用户按下的时候触发

//[button1 addTarget:self action:@selector(touchDown) forControlEvents:UIControlEventTouchDown];

//当用户在触摸控件后在控件之外拖拖动时

//[button1 addTarget:self action:@selector(dragOutside) forControlEvents:UIControlEventTouchDragOutside];

//     当用户在触摸控件后在控件之内拖拖动时

//[button1 addTarget:self action:@selector(dragInside) forControlEvents:UIControlEventTouchDragInside];

//用户控件之外触摸抬按下时

//[button1 addTarget:self action:@selector(outside) forControlEvents:UIControlEventTouchUpOutside];

//触摸控件往外拖时

[button1 addTarget:self action:@selector(dragExit) forControlEvents:UIControlEventTouchDragExit];

//触摸控件往内拖时

[button1 addTarget:self action:@selector(dragEnter) forControlEvents:UIControlEventTouchDragEnter];

//多次触摸控件时触发

[button1 addTarget:self action:@selector(repeat) forControlEvents:UIControlEventTouchDownRepeat];

button1.backgroundColor = [UIColor whiteColor];

button1.titleLabel.font = [UIFont systemFontOfSize:18.0];

[button1 setTitleColor:[UIColor redColor] forState:UIControlStateNormal];

//button1.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;

//button1.contentEdgeInsets = UIEdgeInsetsMake(0, 10, 0, 0);

self.window.backgroundColor = [UIColor purpleColor];

[self.window addSubview:button];
