一。創建不同的一個分類打補丁 button文字圖片顯示類型
typedefNS_ENUM(NSUInteger, MKButtonEdgeInsetsStyle) {
MKButtonEdgeInsetsStyleTop,// image在上，label在下
MKButtonEdgeInsetsStyleLeft,// image在左，label在右
MKButtonEdgeInsetsStyleBottom,// image在下，label在上
MKButtonEdgeInsetsStyleRight// image在右，label在左
};
二。 //.m 里實現方法方法
- (void)layoutButtonWithEdgeInsetsStyle:(MKButtonEdgeInsetsStyle)style
imageTitleSpace:(CGFloat)space
{
// 1.得到imageView和titleLabel的寬、高
CGFloatimageWith =self.imageView.frame.size.width;
CGFloatimageHeight =self.imageView.frame.size.height;
CGFloatlabelWidth =0.0;
CGFloatlabelHeight =0.0;
if([UIDevicecurrentDevice].systemVersion.floatValue>=8.0) {
//由于iOS8中titleLabel的size為0，用下面的這種設置
labelWidth =self.titleLabel.intrinsicContentSize.width;
labelHeight =self.titleLabel.intrinsicContentSize.height;
}else{
labelWidth =self.titleLabel.frame.size.width;
labelHeight =self.titleLabel.frame.size.height;
}
// 2.聲明全局的imageEdgeInsets和labelEdgeInsets
UIEdgeInsetsimageEdgeInsets =UIEdgeInsetsZero;
UIEdgeInsetslabelEdgeInsets =UIEdgeInsetsZero;
// 3.根據style和space得到imageEdgeInsets和labelEdgeInsets的值
switch(style) {
caseMKButtonEdgeInsetsStyleTop:
{
imageEdgeInsets =UIEdgeInsetsMake(-labelHeight-space/2.0,0,0, -labelWidth);
labelEdgeInsets =UIEdgeInsetsMake(0, -imageWith, -imageHeight-space/2.0,0);
}
break;
caseMKButtonEdgeInsetsStyleLeft:
{
imageEdgeInsets =UIEdgeInsetsMake(0, -space/2.0,0, space/2.0);
labelEdgeInsets =UIEdgeInsetsMake(0, space/2.0,0, -space/2.0);
}
break;
caseMKButtonEdgeInsetsStyleBottom:
{
imageEdgeInsets =UIEdgeInsetsMake(0,0, -labelHeight-space/2.0, -labelWidth);
labelEdgeInsets =UIEdgeInsetsMake(-imageHeight-space/2.0, -imageWith,0,0);
}
break;
caseMKButtonEdgeInsetsStyleRight:
{
imageEdgeInsets =UIEdgeInsetsMake(0, labelWidth+space/2.0,0, -labelWidth-space/2.0);
labelEdgeInsets =UIEdgeInsetsMake(0, -imageWith-space/2.0,0, imageWith+space/2.0);
}
break;
default:
break;
}
// 4.賦值
self.titleEdgeInsets= labelEdgeInsets;
self.imageEdgeInsets= imageEdgeInsets;
}
三 。最后調用：首先創建，設置好image 和 title 即使title 是動態的寬度也OK的 我舉得例子是動態寬度的title
UIButton*button = [[UIButtonalloc]init];
CGFloatspace =8;
NSString*textString =self.AllBtns[i];
button.titleLabel.font= [UIFontsystemFontOfSize:14];
//求動態寬度
CGRectrect= [ToolsJJdynamicHeight:textStringsize:14width:20000height:20];
CGFloat width = rect.size.width;
//你可以給width換一個固定的值
button.frame=CGRectMake(labelX,0,width,50);
button.backgroundColor= [UIColoryellowColor];
labelX = labelX + width+20;
[buttonsetTitle:textStringforState:UIControlStateNormal];
[buttonsetImage:[UIImageimageNamed:@"set"]forState:UIControlStateNormal];
//調用分類方法
[buttonlayoutButtonWithEdgeInsetsStyle:MKButtonEdgeInsetsStyleBottomimageTitleSpace:space];
四 。 不是動態寬度固定寬度的button也是可以的
UIButton*button = [[UIButtonalloc]init];
CGFloatspace =8;
NSString*textString =@"wwwww";
button.titleLabel.font= [UIFontsystemFontOfSize:14];
//CGRect rect= [ToolsJJ dynamicHeight:textString size:14 width:20000 height:20];
//CGFloat width = rect.size.width;
//
button.frame=CGRectMake(labelX,0,80,50);
button.backgroundColor= [UIColoryellowColor];
//labelX = labelX + width+20;
[buttonsetTitle:textStringforState:UIControlStateNormal];
[buttonsetImage:[UIImageimageNamed:@"set"]forState:UIControlStateNormal];
[buttonlayoutButtonWithEdgeInsetsStyle:MKButtonEdgeInsetsStyleBottomimageTitleSpace:space];
