Attributes

ScreenshotsInDemo Attribute Name Example
NSDictionary<NSAttributedStringKey, id> *barBtnItemTitleTextAttributes; pickerView.barBtnItemTitleTextAttributes = @{NSFontAttributeName: [UIFont boldSystemFontOfSize:14], NSForegroundColorAttributeName: [UIColor redColor]}
NSString *yearLocale, *monthLocale, *dayLocale; pickerView.yearLocale = @"年";
pickerView.monthLocale = @"月";
pickerView.dayLocale = @"號";

BOOL toolBarPositionBottom;

//默認爲NO,返回和肯定按鈕顯示在頂部，
當設爲YES,返回和肯定按鈕顯示在底部

pickerView.toolBarPositionBottom = YES;

NSArray<NSString *> *topTipBarTitles;

//不爲nil時, toolBarPositionBottom
會自動設置爲YES，底部顯示返回和肯定按鈕，
頂部顯示topTipBarTitles, 如開始日期 - 結束日期

pickerView.topTipBarTitles = @[@"開始日期", @"結束日期"];

CGFloat topTipBarH, toolBarH;

pickerView.topTipBarH = 50;
pickerView.toolBarH = 30;
// 底部顯示返回和肯定按鈕，頂部顯示開始日期 - 結束日期
topTipBarTitles一欄高度，默認是44;
返回和肯定按鈕一欄高度，默認是44

pickerView.topTipBarTitles = @[@"開始日期", @"結束日期"];

BOOL showsDescending;

// 默認升序,結果爲12, 1, 2, 3... 11, 12，
當爲降序，結果爲12, 11, 10, ...4, 3, 2, 1, 12, 僅支持mode是日期類的，如MXPickerViewModeDD...

pickerView.showsDescending = YES;

id selectedTitleOrCustomModels;

//若是值不爲空，則pickerView會把當前值選中，
demo中是把上一個值記錄爲selectedTitleOrCustomModels，
當模式爲MXPickerViewModeCustom, selectedTitleOrCustomModels 應該爲customModels, 是一個 NSArray數組類型, 如 @[@"0-1", @"1-2", @"2-3"]
當模式爲日期一類的，如MXPickerViewModeDD..., selectedTitleOrCustomModels應該爲selectedTitle, 是一個用空格拼接的NSString數組類型, 格式相似於2018 12 12
當模式爲UIDatePicker一類的, 如MXPickerViewModeDateAndTime, selectedTitleOrCustomModels 不該該傳, 默認值老是nil!

//當模式爲MXPickerViewModeCustom
pickerView.selectedTitleOrCustomModels = @[@"0-1", @"1-2", @"2-3"];

//當模式爲日期一類的，如MXPickerViewModeDD...,
pickerView.selectedTitleOrCustomModels = @"12月 1號"
NSDate *minimumDate;
NSDate *maximumDate;
//僅支持mode是日期類的，如MXPickerViewModeDD...


//建立從（今天 - 今天 + 10天），如（1號 - 10號）的列表

//方式1，設置中間的時間間隔，超過當月的最大天數,
代碼內部會取餘deltaBetweenMaxAndMin%最大天數，
推薦方式一
pickerView.minimumDate = [NSDate date];
pickerView.deltaBetweenMaxAndMin = 10;

//方式二, 設置最小日期和最大日期，超過
當月的最大天數,代碼內部會取餘
deltaBetweenMaxAndMin%最大天數
pickerView.minimumDate = [NSDate date];
pickerView.maximumDate = [NSDate dateWithTimeInterval:10 * 24 * 60 * 60 sinceDate:pickerView.minimumDate];


CGFloat componentWidth;
//設置每一個component的寬度，等寬，若是不設置，
默認爲pickerView.bounds.size.width/numberOfComponents

pickerView.componentWidth = 100;
//每一列component列寬都爲100

CGFloat componentRowHeight;
//設置每一個component的行高，若是不設置，默認爲40

pickerView.componentRowHeight = 100;

CGFloat (^configPickerViewWidthForComponentBlock)(MXPickerView *mxPickerView, UIPickerView *pickerView, NSInteger component)
//爲每一個component設置不一樣的寬度,相同的能夠直接設置pickerView.componentWidth = xx

pickerView.configPickerViewWidthForComponentBlock = ^CGFloat(MXPickerView *mxPickerView, UIPickerView *pickerView, NSInteger component) { return (component == 0 || component == 3) ? 80 : (mxPickerView.bounds.size.width - 2 * 80)/4;};

CGFloat(^configPickerViewRowHeightForComponentBlock)(MXPickerView *mxPickerView, UIPickerView *pickerView, NSInteger component)
//爲每一個component設置相同的行高, 等價於pickerView.componentRowHeight = xx

pickerView.configPickerViewRowHeightForComponentBlock = ^CGFloat(MXPickerView *mxPickerView, UIPickerView *pickerView, NSInteger component) {return 100;};

NSString * (^configPickerViewTitleForRowForComponentBlock)(MXPickerView *mxPickerView, UIPickerView *pickerView, NSInteger row, NSInteger component);
//設置每一行的title

pickerView.configPickerViewTitleForRowForComponentBlock = ^NSString *(MXPickerView *mxPickerView, UIPickerView *pickerView, NSInteger row, NSInteger component) {return @"row content";};

NSAttributedString * (^configPickerViewAttributedTitleForRowForComponentBlock)(MXPickerView *mxPickerView, UIPickerView *pickerView, NSInteger row, NSInteger component)
//設置每一行的attributedTitle

pickerView.configPickerViewAttributedTitleForRowForComponentBlock = ^NSAttributedString *(MXPickerView *mxPickerView, UIPickerView *pickerView, NSInteger row, NSInteger component) {return [[NSAttributedString alloc] initWithString:@"attributed title" attributes:@{NSForegroundColorAttributeName:[UIColor purpleColor]}];};

void (^configPickerViewContentLabelAppearanceForRowForComponentBlock)(MXPickerView *mxPickerView, UIPickerView *pickerView, UILabel *contentLabel, NSInteger row, NSInteger component);
//設置 content label 的樣式，如字體，文字對齊方式，背景顏色等...

pickerView.configPickerViewContentLabelAppearanceForRowForComponentBlock = ^(MXPickerView *mxPickerView, UIPickerView *pickerView, UILabel *contentLabel, NSInteger row, NSInteger component){ contentLabel.backgroundColor = [UIColor yellowColor];//黃色 contentLabel.textAlignment = NSTextAlignmentRight;};//右對齊

UIView * (^configPickerViewViewForRowForComponentBlock)(MXPickerView *mxPickerView, UIPickerView *pickerView, NSInteger row, NSInteger component, UIView *reusingView);
//自定義在component中的contentView

pickerView.configPickerViewViewForRowForComponentBlock = ^UIView *(MXPickerView *mxPickerView, UIPickerView *pickerView, NSInteger row, NSInteger component, UIView *reusingView) {return [UIButton buttonWithType:UIButtonTypeContactAdd];//返回UIButtonTypeContactAdd};
