UIDatePicker 基本设置-显示已经选择的日期 并设置最大、最小日期

// 1.日期Picker UIDatePicker *datePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 0, __kScreenWidth, __kDatePickerH)]; datePicker.backgroundColor = [UIColor whiteColor]; // 1.1选择datePickr的显示风格 [datePicker setDatePickerMode:UIDatePickerModeDate]; // 1.2查询所有可用的地区 //NSLog(@"%@", [NSLocale availableLocaleIdentifiers]); // 1.3设置datePickr的地区语言, zh_Han后面是s的就为简体中文,zh_Han后面是t的就为繁体中文 [datePicker setLocale:[[NSLocale alloc] initWithLocaleIdentifier:@"zh_Hans_CN"]]; // 1.4监听datePickr的数值变化 [datePicker addTarget:self action:@selector(dateChanged:) forControlEvents:UIControlEventValueChanged]; // NSDate *date = [NSDate date]; NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateFormat:@"yyyy-MM-dd"]; NSDate *date = [dateFormatter dateFromString:lastTime];//上次设置的日期 if (!lastTime) { date = [NSDate date]; } // 2.3 将转换后的日期设置给日期选择控件 [datePicker setDate:date]; NSDate * timeDate=[NSDate date]; NSDateFormatter *fmt = [[NSDateFormatter alloc] init]; fmt.dateFormat = @"yyyy-MM-dd"; NSDate *minDate = [fmt dateFromString:@"1930-1-1"]; //设置日期最大及最小值 datePicker.maximumDate = timeDate; datePicker.minimumDate = minDate; //设置字体颜色 [datePicker setValue:kColor3C3C3C forKeyPath:@"textColor"]; [self addSubview:datePicker];
