简书地址iOS的GridView表格视图的实现

定义的枚举类型和结构体

//use for representing the location in gridview
typedef struct GridIndex {
    long row;
    long col;
} GridIndex;

//use for specifing the selection type
typedef enum{
    JHGridSelectTypeNone,       //default, none selection can be seen
    JHGridSelectTypeDefault,    //when click on an item, the whole line will be selected also
    JHGridSelectTypeSingle,     //only select the clicked item
}JHGridSelectType;

//use for specifing the alignment type
typedef enum{
    JHGridAlignmentTypeDefault, //center alignment
    JHGridAlignmentTypeLeft,    //left alignment
    JHGridAlignmentTypeRight,   //right alignment
}JHGridAlignmentType;

分别是用于表示位置坐标的GridIndex（类似NSIndexPath），用于表示选择样式的JHGridSelectType和用于表示对齐方式的JHGridAlignmentType

可实现的代理方法

@protocol JHGridViewDelegate<NSObject>

@optional
- (CGFloat)heightForRowAtIndex:(long)index;
@optional
- (CGFloat)widthForColAtIndex:(long)index;
@optional
- (CGFloat)heightForTitles;
@optional
- (BOOL)isTitleFixed;
@optional
- (void)didSelectRowAtGridIndex:(GridIndex)gridIndex;
@optional
- (JHGridSelectType)gridViewSelectType;
@optional
- (JHGridAlignmentType)gridViewAlignmentType;
@optional
- (UIColor *)backgroundColorForTitleAtIndex:(long)index;
@optional
- (UIColor *)backgroundColorForGridAtGridIndex:(GridIndex)gridIndex;
@optional
- (UIColor *)textColorForTitleAtIndex:(long)index;
@optional
- (UIColor *)textColorForGridAtGridIndex:(GridIndex)gridIndex;
@optional
- (UIFont *)fontForTitleAtIndex:(long)index;
@optional
- (UIFont *)fontForGridAtGridIndex:(GridIndex)gridIndex;
@end

其中比较常用的有

- (void)didSelectRowAtGridIndex:(GridIndex)gridIndex;

用于处理表格元素被选中的事件

- (BOOL)isTitleFixed;

用于表示标题栏是否固定，默认为NO

`JHGridView` 的方法

//init methods
- (instancetype)initWithFrame:(CGRect)frame;

//call this methods to load the gridview
- (void)setTitles:(NSArray<NSString *> *)titles andObjects:(NSArray *)objects withTags:(NSArray<NSString *> *)tags;

第二个方法在需要显示数据的时候调用，传入一个标题（表头行）的NSString数组，一堆需要显示用的数据的model数组，以及每一列对应model中属性名称的NSString数组（用于KVC赋值）

使用Demo

使用该控件时把JHGridView目录拖入工程如果不需要指定颜色、字体大小、行高列宽以及处理选中事件的可以不实现代理方法

#import "JHGridView.h"
@interface ViewController ()<JHGridViewDelegate>

初始化并赋值

JHGridView *gridView = [[JHGridView alloc] initWithFrame:
                        CGRectMake(0, 64, self.view.frame.size.width, 300)];
gridView.delegate = self;
NSArray *array = @[
                   [[TestObject alloc] initWithName:@"aaa" Sex:@"11" Number:@"ooo" Address:@"sdfabfsakjbakf" Birthday:@"1996-01-01"],
                   [[TestObject alloc] initWithName:@"aaa" Sex:@"11" Number:@"ooo" Address:@"sdfabfsakjbakf" Birthday:@"1996-01-02"],
                   [[TestObject alloc] initWithName:@"aaa" Sex:@"11" Number:@"ooo" Address:@"sdfabfsakjbakf" Birthday:@"1996-01-03"],
                   [[TestObject alloc] initWithName:@"aaa" Sex:@"11" Number:@"ooo" Address:@"sdfabfsakjbakf" Birthday:@"1996-01-04"],
                   [[TestObject alloc] initWithName:@"aaa" Sex:@"11" Number:@"ooo" Address:@"sdfabfsakjbakf" Birthday:@"1996-01-05"],
                   [[TestObject alloc] initWithName:@"aaa" Sex:@"11" Number:@"ooo" Address:@"sdfabfsakjbakf" Birthday:@"1996-01-06"],
                   [[TestObject alloc] initWithName:@"aaa" Sex:@"11" Number:@"ooo" Address:@"sdfabfsakjbakf" Birthday:@"1996-01-07"],
                   [[TestObject alloc] initWithName:@"aaa" Sex:@"11" Number:@"ooo" Address:@"sdfabfsakjbakf" Birthday:@"1996-01-08"],
                   [[TestObject alloc] initWithName:@"aaa" Sex:@"11" Number:@"ooo" Address:@"sdfabfsakjbakf" Birthday:@"1996-01-09"],
                   [[TestObject alloc] initWithName:@"aaa" Sex:@"11" Number:@"ooo" Address:@"sdfabfsakjbakf" Birthday:@"1996-01-10"],
                   [[TestObject alloc] initWithName:@"aaa" Sex:@"11" Number:@"ooo" Address:@"sdfabfsakjbakf" Birthday:@"1996-01-11"]];
[gridView setTitles:@[@"NAME",
                      @"SEX",
                      @"PHONE",
                      @"ADDRESS",
                      @"BIRTHDAY"]
         andObjects:array withTags:@[@"name",@"sex",@"number",@"address",@"birthday"]];
[self.view addSubview:gridView];

如果需要自定义，则实现代理方法

- (void)didSelectRowAtGridIndex:(GridIndex)gridIndex{
    NSLog(@"selected at\ncol:%ld -- row:%ld", gridIndex.col, gridIndex.row);
}

- (BOOL)isTitleFixed{
    return YES;
}

- (CGFloat)widthForColAtIndex:(long)index{
    if (index==3||index==4) {
        return 120;
    }else{
        return 90;
    }
}

- (UIColor *)backgroundColorForTitleAtIndex:(long)index{
    return [UIColor colorWithRed:229/255.0 green:114/255.0 blue:30/255.0 alpha:1];
}

- (UIColor *)backgroundColorForGridAtGridIndex:(GridIndex)gridIndex{
    if (gridIndex.row == 2) {
        return [UIColor cyanColor];
    }else if (gridIndex.col == 4){
        return [UIColor yellowColor];
    }else{
        return [UIColor whiteColor];
    }
}

- (UIColor *)textColorForTitleAtIndex:(long)index{
    if (index==1) {
        return [UIColor whiteColor];
    }else{
        return [UIColor blackColor];
    }
}

- (UIColor *)textColorForGridAtGridIndex:(GridIndex)gridIndex{
    if (gridIndex.col == 1) {
        return [UIColor blueColor];
    }else{
        return [UIColor blackColor];
    }
}

- (UIFont *)fontForTitleAtIndex:(long)index{
    return [UIFont systemFontOfSize:20];
}
