我创建了一个自定义 UIView (ProgressView),在其中绘制了通过 StyleKit 从 PaintCode 导入的形状。
下面是代码。我在自定义 UIView 中声明了实例变量属性,当我尝试从 ViewController 更改属性时,它不起作用。
进度视图.h
#import <UIKit/UIKit.h>
@interface ProogressView : UIView
@property (nonatomic) float daysFraction;
@property (nonatomic) float pagesFraction;
@end
进度视图.m
#import "ProgressView.h"
#import "StyleKitName.h"
#import "ViewController.h"
@implementation ProgressView
@synthesize daysFraction = _daysFraction;
@synthesize pagesFraction = _pagesFraction;
- (void)drawRect:(CGRect)rect {
// Drawing code
[StyleKitName drawCanvas1WithDaysFraction:self.daysFraction pageFraction:self.pagesFraction];
}
-(void)awakeFromNib {
[super awakeFromNib];
self.pagesFraction = 0;
self.daysFraction = 0;
}
视图控制器.h
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController
@end
*ViewController.m**
#import "ViewController.h"
#import "ButtonAnimation.h"
#import "ProgressView.h"
#import "StyleKitName.h"
@interface ViewController ()
@property (weak, nonatomic) IBOutlet ButtonAnimation *buttonView;
@property (weak, nonatomic) IBOutlet UIButton *actionButton;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
ProgressView *new =[[ ProgressView alloc]init];
new.daysFraction = 0.7f; // here I am setting value to variable in custom view ProgressView but not working.
}
- (IBAction)animateTheButton:(id)sender {
self.buttonView.layer.backgroundColor = [UIColor clearColor].CGColor;
[self.buttonView addErrorAnimation];
}
@end
