Draw on a mature news software, standing on the shoulders of giants. How is it implemented?

Two parts: Scrolling picture news + can scroll to select the News category menu.

1. Scrolling picture news: [Uiscrollview ...]

#pragmaMark-Load Picture scrolling view-(void) Setpicscrollview{uiscrollview* Picscroll=[[uiscrollviewalloc] Initwithframe:cgrectmake (0, titleviewy+ $, Kwidth, the)];_picscroll=Picscroll; Picscroll.contentsize=cgsizemake (kwidth* (_picarray.count+2),0); Picscroll.contentoffset=cgpointmake (Kwidth,0); Picscroll.showshorizontalscrollindicator=NO; Picscroll.pagingenabled=YES; Picscroll.Delegate=Self ; [Self.viewaddSubview:picScroll];//Add a previous page viewUiimageview * Preview=[[uiimageviewalloc] Initwithframe:cgrectmake (0,0, Kwidth, the)]; NSString* Path1=[[nsbundlemainbundle] Pathforresource:@"Mountain"OfType:@"jpg"]; Preview.image=[uiimageimagewithcontentsoffile:path1]; [Picscroll Addsubview:preview];//Add a later Page viewUiimageview * Lastview=[[uiimageviewalloc] Initwithframe:cgrectmake (kwidth*6,0, Kwidth, the)]; NSString* Path2=[[nsbundlemainbundle] Pathforresource:@"TS"OfType:@"jpg"]; Lastview.image=[Uiimageimagewithcontentsoffile:path2]; [Picscroll Addsubview:lastview]; for(intI=0; i<_picarray.count; i++) {Uiimageview* Img=[[uiimageviewalloc] Initwithframe:cgrectmake (kwidth* (i+1),0, Kwidth, the)]; NSString* path=[[Nsbundlemainbundle] pathforresource:_picarray[i] oftype:nil]; UIImage* image=[Uiimageimagewithcontentsoffile:path]; Img.image=image; [Picscroll addsubview:img]; UILabel* Describe=[[uilabelalloc] Initwithframe:cgrectmake (0,145,260, $)]; Describe.text=_plistarray[i][@"title"]; Describe.textcolor=[Uicolororangecolor];    [img Addsubview:describe]; }uipagecontrol* Pagecontrol=[[uipagecontrolalloc] Initwithframe:cgrectmake ( the, titleviewy+ $+ the- $, the, $)];_pagecontrol=Pagecontrol; Pagecontrol.numberofpages=5; Pagecontrol.pageindicatortintcolor=[Uicolorgreencolor]; Pagecontrol.currentpageindicatortintcolor=[Uicolorredcolor]; [Self.viewaddSubview:pageControl];}

2, refine the news category: [Uiscrollview ...]

//= = =---category title scrolling view---= = =Uiscrollview * Scrollview=[[uiscrollviewalloc] Initwithframe:cgrectmake (0, Titleviewy, Kwidth, $)]; Scrollview.backgroundcolor=[uicolorcolorwithred:0.5green:0.3blue:0.2alpha:0.6];_titlescroll=ScrollView; Scrollview.showshorizontalscrollindicator=NO; Scrollview.contentsize=cgsizemake ( About*_titlearray.count,0); [Self.viewaddSubview:scrollView]; for(intI=0; i<_titlearray.count; i++) {UIButton* Button=[[uibuttonalloc] Initwithframe:cgrectmake ( About*i,0, About, $)];        [Button settitle:_titlearray[i] forstate:uicontrolstatenormal]; Button.tag=i;        [Button Settitlecolor:[uicolorwhitecolor] forstate:uicontrolstatenormal];        [Button Settitlecolor:[uicolorgreencolor] forstate:uicontrolstateselected];        [Button addtarget:selfaction: @selector (Clickbutton:) forcontrolevents:uicontroleventtouchupinside];    [ScrollView Addsubview:button]; }}

Category of news menu, also note that to make the name of the currently selected news class font size or font change color, at this time, there are many ways to choose, in this "take only one scoop";

Use tag values and arrays to add and judge. difficult to achieve;

#pragmaMark-Add a Click event to the button-(void) Clickbutton: (UIButton *) Button{nsarray* array1=_titlescroll.subviews; Nsmutablearray* array=[Nsmutablearrayarraywitharray:array1]; [Array removelastobject]; for(UIButton * binchArray) {b.selected=NO;//NSLog (@ "%ld", B.tag);B.titlelabel.font=[uifontsystemfontofsize: -]; } button.selected=YES; Button.titleLabel.font=[uifontsystemfontofsize: -];    [Button Settitlecolor:[uicolor Greencolor] forstate:uicontrolstatenormal]; Button.titleLabel.adjustsFontSizeToFitWidth=YES;}

Of course, there are other ways to make it easy:

①: Use a button to record the previous selected button.

②: The tag value of the selected button is stored in the array, or the button is stored directly, if the button in the array changes state, otherwise, the state is restored.
