以UIView为例:
UIView *view1 = [UIView new];
view1.sd_layout都是点语法
距离左边:view1.sd_layout.leftSpaceToView(self.view,20)
参数1是view1左边以哪个视图为基准,参数2是具体的数值距离上下右就把left换成对应的位置就行
对齐:leftEqualToView(self.view,20) 需要其它对齐,将左变成需要的位置
宽高:1.具体数值:heightIs(100)widthIs(20)
2.根据其他视图的比例来:heightRatioToView(self.view,0.5)
view1的高是view的0.5倍,就是一半
widthRatioToView(self.view,0.5)
view1的高是view的0.5倍,就是一
中心:centerYEqualToView(self.view)centerXEqualToView(self.view)
Label内容自适应:
① label的父视图根据label的高度自适应
UILabel*subview1 = [UILabelnew];//初始化子label
subview1.text=@"这个label会根据这些文字内容高度自适应；而这个父view会根据label和view具体情况实现高度自适应。\nGot
it! OH YAEH!这个label会根据这些文字内容高度自适应；而这个父view会根据label和view具体情况实现高度自适应。\nGot
it! OH YAEH!";
UIView*subview2 = [UIViewnew];//初始化子view2
subview2.backgroundColor= [UIColororangeColor];
//将子view添加进父view
[self.view1sd_addSubviews:@[subview1,
subview2]];
subview1.sd_layout
.leftSpaceToView(self.view1,10)
.rightSpaceToView(self.view1,10)
.topSpaceToView(self.view1,10)
.autoHeightRatio(0);//设置文本内容自适应，如果这里的参数为大于0的数值则会以此数值作为view的高宽比设置view的高度
subview2.sd_layout
.topSpaceToView(subview1,10)
.widthRatioToView(subview1,1)
.heightIs(30)
.leftEqualToView(subview1);
//view1使用高度根据子view内容自适应，所以不需要设置高度，而是设置“[self.view1
setupAutoHeightWithBottomView:testView bottomMargin:10];”实现高度根据内容自适应
self.view1.sd_layout
.leftSpaceToView(self.view,10)
.topSpaceToView(self.view,80)
.rightSpaceToView(self.view,10);
//设置view1高度根据子其内容自适应
[self.view1setupAutoHeightWithBottomView:subview2bottomMargin:10];
②label宽度自适应
UILabel*autoWidthlabel = [UILabelnew];
autoWidthlabel.backgroundColor= [[UIColororangeColor]colorWithAlphaComponent:0.5];
_autoWidthLabel= autoWidthlabel;
autoWidthlabel.font= [UIFontsystemFontOfSize:12];
autoWidthlabel.text=@"宽度自适应(距离父view右边距10)";
[self.viewaddSubview:autoWidthlabel];
autoWidthlabel.sd_layout
.rightSpaceToView(self.view,10)
.heightIs(20)
.bottomSpaceToView(self.view,50);
[autoWidthlabelsetSingleLineAutoResizeWithMaxWidth:180];
③label高度自适应
UILabel*autoHeightlabel = [UILabelnew];
autoHeightlabel.backgroundColor= [[UIColorredColor]colorWithAlphaComponent:0.5];
autoHeightlabel.font= [UIFontsystemFontOfSize:12];
autoHeightlabel.text=@"高度自适应(距离父view左边距10，底部和其右侧label相同，宽度为100)";
[self.viewaddSubview:autoHeightlabel];
autoHeightlabel.sd_layout
.bottomEqualToView(_autoWidthLabel)
.leftSpaceToView(self.view,10)
.widthIs(100)
.autoHeightRatio(0);
设置一排固定间距自动宽度子view
- (void)setupAutoWidthViewsWithCount:(NSInteger)count margin:(CGFloat)margin
{
_autoWidthViewsContainer= [UIViewnew]; //放button的父视图
_autoWidthViewsContainer.backgroundColor= [UIColorgreenColor];
[self.viewaddSubview:_autoWidthViewsContainer];
NSMutableArray*temp = [NSMutableArraynew];
for(inti =0; i < count; i++) {
UIView*view = [UIViewnew];
view.backgroundColor= [UIColororangeColor];
[_autoWidthViewsContaineraddSubview:view];
view.sd_layout.autoHeightRatio(0.5);//设置高度约束
[tempaddObject:view];
}
_autoWidthViewsContainer.sd_layout
.leftSpaceToView(self.view,10)
.rightSpaceToView(self.view,10)
.topSpaceToView(_centerButton,10);
//此步设置之后_autoWidthViewsContainer的高度可以根据子view自适应
[_autoWidthViewsContainersetupAutoWidthFlowItems:[tempcopy]withPerRowItemsCount:countverticalMargin:marginhorizontalMargin:margin];
}
设置一排固定宽度自动间距子view
- (void)setupAutoMarginViewsWithCount:(NSInteger)count itemWidth:(CGFloat)itemWidth
{
_autoMarginViewsContainer= [UIViewnew];
_autoMarginViewsContainer.backgroundColor= [UIColorblueColor];
[self.viewaddSubview:_autoMarginViewsContainer];
NSMutableArray*temp = [NSMutableArraynew];
for(inti =0; i < count; i++) {
UIView*view = [UIViewnew];
view.backgroundColor= [UIColororangeColor];
[_autoMarginViewsContaineraddSubview:view];
view.sd_layout.autoHeightRatio(0.5);//设置高度约束
[tempaddObject:view];
}
_autoMarginViewsContainer.sd_layout
.leftSpaceToView(self.view,10)
.rightSpaceToView(self.view,10)
.topSpaceToView(_autoWidthViewsContainer,10);
//此步设置之后_autoMarginViewsContainer的高度可以根据子view自适应
[_autoMarginViewsContainersetupAutoMarginFlowItems:[tempcopy]withPerRowItemsCount:countitemWidth:itemWidthverticalMargin:10];
}
cell高度自适应
第一步:在自定义cell的.m文件里面,写上这个
[selfsetupAutoHeightWithBottomView:_view4bottomMargin:10];
// view4是在cell所有的子视图里面最下面的view
第二步:在返回cell高度的方法里面
intindex = indexPath.row%5;
NSString*str =_textArray[index];
// >>>>>>>>>>>>>>>>>>>>> * cell自适应步骤2 * >>>>>>>>>>>>>>>>>>>>>>>>
/* model为模型实例，keyPath为model的属性名，通过kvc统一赋值接口*/ keypath:比如你要显示的是str,str对应的model的属性是text
return[self.tableViewcellHeightForIndexPath:indexPathmodel:strkeyPath:@"text"cellClass:[TestCell2class]contentViewWidth:[selfcellContentViewWith]];
attributedString
// --------- attributedString测试：行间距为8 ---------------------------
NSString*text =@"attributedString";
NSMutableParagraphStyle* paragraphStyle = [[NSMutableParagraphStylealloc]init];
[paragraphStylesetLineSpacing:8];
UIColor*color = [UIColorblackColor];
NSAttributedString*string = [[NSAttributedStringalloc]initWithString:textattributes:@{NSForegroundColorAttributeName: color,NSParagraphStyleAttributeName:
paragraphStyle}];
UILabel*label = [UILabelnew];
[self.viewaddSubview:label];
label.attributedText= string;
label.sd_layout
.leftSpaceToView(self.view,10)
.rightSpaceToView(self.view,10)
.topSpaceToView(self.view,70)
.autoHeightRatio(0);
//标注lable的text为attributedString
label.isAttributedContent=YES;
view的动态圆角处理以及UIScrollview的高度自适应,要想显示的是圆,前提是view的宽高相等
UIScrollView*scrollView = [UIScrollViewnew];
[self.viewaddSubview:scrollView];
[scrollViewsd_addSubviews:@[self.view0,self.view1,self.view2,self.view3,self.view4,self.view5,self.view6,self.view7,self.view8]];
scrollView.sd_layout.spaceToSuperView(UIEdgeInsetsZero);
self.view0.sd_layout
.leftSpaceToView(scrollView,20)
.rightSpaceToView(scrollView,20)
.topSpaceToView(scrollView,20)
.heightIs(150);
self.view1.sd_layout
.widthIs(200)
.heightIs(200)
.centerXEqualToView(scrollView)
.topSpaceToView(self.view0,20);
self.view2.sd_layout
.leftSpaceToView(scrollView,50)
.rightSpaceToView(scrollView,50)
.topSpaceToView(self.view1,20)
.heightIs(150);
self.view3.sd_layout
.widthIs(250)
.heightEqualToWidth()
.centerXEqualToView(scrollView)
.topSpaceToView(self.view2,20);
// scrollview自动contentsize
[scrollViewsetupAutoContentSizeWithBottomView:self.view3bottomMargin:20];
//设置圆角
self.view0.sd_cornerRadiusFromHeightRatio=@(0.5);//设置view0的圆角半径为自身高度的0.5倍
self.view1.sd_cornerRadiusFromWidthRatio=@(0.5);
self.view2.sd_cornerRadiusFromWidthRatio=@(0.5);
