First look at the effect

The main is to complete the nine grid UI construction

Code

- (void) Viewdidload {[SuperViewdidload];//Nine the width of each lattice in the grid#define KAPPVIEWW//Nine the height of each lattice in the grid#define KAPPVIEWHHow many squares are there in the////nine lattice?#define KCOLCOUNT 3//Nine the first line of the grid from the top edge of the screen#define Kstarty    /* Idea: Place three controls in a view without wrapping through a double for loop, but by using the first and then judging his rows and columns to position his XY coordinates to complete 012 in line one: equivalent to I/kcolcount//row line: 122 lines:     3,453 rows: 678 int row = I/kcolcount;     Column: 362 columns: 147 int col = I%kcolcount; */    //per line interval    CGFloatMarginx = ( Self. View. Frame. Size. Width-KCOLCOUNT*KAPPVIEWW)/(kcolcount+1);//interval for each column    CGFloatMarginy =Ten; for(intI=0; i< A; i++) {//Row line: 122 lines: 3,453 lines: 678        introw = I/kcolcount;//Column column: 362 columns: 147        intcol = I%kcolcount;CGFloatx = Marginx + col* (MARGINX+KAPPVIEWW);//x coordinate of each view        CGFloaty = kstarty + +marginy + row * (Marginy + KAPPVIEWH);//y-coordinate of each view        UIView*appview = [[UIViewAlloc] Initwithframe:cgrectmake (x, Y, Kappvieww, KAPPVIEWH)]; [ Self. ViewAddsubview:appview];//Implement view interior details        nsdictionary*dict = Self. Applist[i];//Get every dictionary element in the Applist (Image caption Button image)        //uiimageview: Application picture        Uiimageview*icon = [[UiimageviewAlloc] Initwithframe:cgrectmake (0,0, KAPPVIEWW, -)];//icon. backgroundcolor = [Uicolor redcolor];Icon.

Contentmode= Uiviewcontentmodescaleaspectfit;//fill's going to be bigger.[Appview Addsubview:icon];//uilabel: Application name        UILabel*label = [[UILabelAlloc] Initwithframe:cgrectmake (0, Cgrectgetmaxy (icon. Frame), KAPPVIEWW, -)]; Label. Text= dict[@"Name"]; Label. Font= [UifontSystemfontofsize:13.0]; Label. TextAlignment= Nstextalignmentcenter; [Appview Addsubview:label];//uibutton: Application Download button        UIButton*button = [[UIButtonAlloc] Initwithframe:cgrectmake (0, Cgrectgetmaxy (label.

Titlelabel. Font= [UifontSystemfontofsize:12.0];      [Appview Addsubview:button]; }    }

Ideas

Idea: Put three controls in a view
Does not wrap through a double for loop, but passes through the first and then judges his row and column to locate his XY coordinate complete
012 in the first line: equivalent to I/kcolcount
Row line: 122 lines: 3,453 lines: 678
int row = I/kcolcount;
Column: 362 columns: 147
int col = I%kcolcount;

Algorithm analysis diagram

Watch out.

Setting the picture and setting the picture is a little different, if the last set to Uiviewcontentmodescaleaspectfit will be beyond the defined border, according to the original pixel size to decorate.
Icon.image = [UIImage imagenamed:dict[@ "icon"];
Icon.contentmode = Uiviewcontentmodescaleaspectfit;

Font settings for Uilabel;uibutton

        //设置标题        label.text = dict[@"name"];        //设置字体大小        label.font = [UIFont systemFontOfSize:13.0];        //设置Label居中        label.textAlignment = NSTextAlignmentCenter;

button font settings

[button setTitle:@"下载" forState:UIControlStateNormal];        // *** 一定不要使用以下方法，修改按钮标题        //        button.titleLabel.text = @"aaa";        // 修改字体（titleLabel是只读的）        // readonly表示不允许修改titleLabel的指针，但是可以修改label的字体        // 提示：按钮的字体是不区分状态的！        button.titleLabel.font = [UIFont systemFontOfSize:12.0];
