1:扇形进度视图及运用

首先先创建扇形的视图,传入进度值

#import <UIKit/UIKit.h>

@interface LHProgressView : UIView

@property (nonatomic) float progress;

@end
#import "LHProgressView.h"
#define MinProgress (1.0 / 16.0) @implementation LHProgressView - (id)initWithFrame:(CGRect)frame
{
if (self = [super initWithFrame:frame]) {
self.backgroundColor = [UIColor clearColor];
_progress = MinProgress;
}
return self;
} - (void)drawRect:(CGRect)rect
{ CGContextRef context = UIGraphicsGetCurrentContext(); CGContextFillPath(context);
CGRect aRect= CGRectMake(, , self.bounds.size.width - , self.bounds.size.height - );
CGContextSetRGBStrokeColor(context, 1.0, 1.0, 1.0, 0.9);
CGContextSetLineWidth(context, 2.0);
CGContextAddEllipseInRect(context, aRect);
CGContextDrawPath(context, kCGPathStroke); CGFloat centerX = self.bounds.size.width / ;
CGFloat centerY = self.bounds.size.height / ; UIColor *aColor = [UIColor colorWithRed:1.0 green:1.0 blue:1.0 alpha:0.9];
CGContextSetFillColorWithColor(context, aColor.CGColor);
CGContextSetLineWidth(context, 0.0);
CGContextMoveToPoint(context, centerX, centerY);
CGContextAddArc(context, centerX, centerY, (self.bounds.size.width - ) / , - M_PI_2, - M_PI_2 + self.progress * *M_PI, );
CGContextClosePath(context);
CGContextDrawPath(context, kCGPathFillStroke); } - (void)setProgress:(float)progress
{
_progress = progress; if (_progress < MinProgress) {
_progress = MinProgress;
} if (_progress >= 1.0) { [self setNeedsDisplay];
[self removeFromSuperview]; } else { [self setNeedsDisplay]; } } @end

运用:

@property(nonatomic, strong)LHProgressView *progressView;
-(instancetype)initWithFrame:(CGRect)frame
{
if (self = [super initWithFrame:frame]) { self.backgroundColor = [UIColor clearColor]; _progressView = [[LHProgressView alloc] init]; } return self;
}
- (void)setItemImageUrl:(NSString *)itemImageUrl
{
_itemImageUrl = itemImageUrl; BOOL imageExist = [[SDWebImageManager sharedManager] cachedImageExistsForURL:[NSURL URLWithString:itemImageUrl]]; if (_itemImageProgress == 1.0 || imageExist) { [_progressView removeFromSuperview]; } else { _progressView.bounds = CGRectMake(, , , );
_progressView.center = CGPointMake((self.bounds.size.width) / , (self.bounds.size.height) / );
[self addSubview:_progressView]; _progressView.progress = _itemImageProgress; } _itemImageView.image = _itemImage; [self resetSize]; __weak LHProgressView *progressView = _progressView;
__weak LHPhotoView *photoView = self;
NSInteger index = self.tag - ; [[SDWebImageManager sharedManager] downloadImageWithURL:[NSURL URLWithString:itemImageUrl] options:SDWebImageRetryFailed | SDWebImageLowPriority progress:^(NSInteger receivedSize, NSInteger expectedSize) { if ([photoView.photoViewDelegate respondsToSelector:@selector(photoIsShowingPhotoViewAtIndex:)]) {
BOOL isShow = [photoView.photoViewDelegate photoIsShowingPhotoViewAtIndex:index]; if (isShow) {
if (receivedSize > kMinProgress) {
progressView.progress = (float)receivedSize/expectedSize;
}
} } if ([photoView.photoViewDelegate respondsToSelector:@selector(updatePhotoProgress:andIndex:)]) {
[photoView.photoViewDelegate updatePhotoProgress:(float)receivedSize/expectedSize andIndex:index];
} } completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, BOOL finished, NSURL *imageURL) { if (image) {
if ([photoView.photoViewDelegate respondsToSelector:@selector(photoIsShowingPhotoViewAtIndex:)]) {
BOOL isShow = [photoView.photoViewDelegate photoIsShowingPhotoViewAtIndex:index]; if (isShow) {
photoView.itemImageView.image = image; [self resetSize];
} } if ([photoView.photoViewDelegate respondsToSelector:@selector(updatePhotoProgress:andIndex:)]) {
[photoView.photoViewDelegate updatePhotoProgress:1.0 andIndex:index];
}
} }]; }

注意:在break里面要先处理一下对象__weak LHProgressView *progressView = _progressView;上面也用到SDWebImage进行图片加载,并把进度赋值

2:Delegate运用在开放事件中

#import <UIKit/UIKit.h>
@class DMDropDownMenu; @protocol DMDropDownMenuDelegate <NSObject> - (void)selectIndex:(NSInteger)index AtDMDropDownMenu:(DMDropDownMenu *)dmDropDownMenu; @end
@interface DMDropDownMenu : UIView

@property(nonatomic,assign)id<DMDropDownMenuDelegate>delegate;

@end
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self tapAction];
_curText.text = self.listArr[indexPath.row];
if ([_delegate respondsToSelector:@selector(selectIndex:AtDMDropDownMenu:)]) {
[_delegate selectIndex:indexPath.row AtDMDropDownMenu:self];
}
}

运用时三步代码:

@interface ViewController ()<DMDropDownMenuDelegate>
@end DMDropDownMenu * dm1 = [[DMDropDownMenu alloc] initWithFrame:CGRectMake(, , , )];
dm1.delegate = self;
[self.view addSubview:dm1]; - (void)selectIndex:(NSInteger)index AtDMDropDownMenu:(DMDropDownMenu *)dmDropDownMenu
{
NSLog(@"dropDownMenu:%@ index:%d",dmDropDownMenu,index);
}

 3:UINavigationController的封装

#import <UIKit/UIKit.h>
#import "UIColor+KSString.h"
@interface KSNavigationController : UINavigationController @end
#import "KSNavigationController.h"

@interface KSNavigationController ()<UIGestureRecognizerDelegate>

@end

@implementation KSNavigationController

- (void)viewDidLoad {
[super viewDidLoad];
//设置手势代理
self.interactivePopGestureRecognizer.delegate = self;
//设置NavigationBar
[self setupNavigationBar];
} //设置导航栏主题
- (void)setupNavigationBar
{
UINavigationBar *appearance = [UINavigationBar appearance];
//统一设置导航栏颜色,如果单个界面需要设置,可以在viewWillAppear里面设置,在viewWillDisappear设置回统一格式。
[appearance setBarTintColor:[UIColor getColor:@"fb9c0a"]]; //导航栏title格式
NSMutableDictionary *textAttribute = [NSMutableDictionary dictionary];
textAttribute[NSForegroundColorAttributeName] = [UIColor whiteColor];
textAttribute[NSFontAttributeName] = [UIFont systemFontOfSize:];
[appearance setTitleTextAttributes:textAttribute];
} - (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
{
if (self.viewControllers.count > ) {
viewController.hidesBottomBarWhenPushed = YES;
UIButton *backButton = [[UIButton alloc]initWithFrame:CGRectMake(, , , )];
[backButton setImage:[UIImage imageNamed:@"back"] forState:UIControlStateNormal];
[backButton setImage:[UIImage imageNamed:@"back"] forState:UIControlStateHighlighted];
[backButton setImageEdgeInsets:UIEdgeInsetsMake(, -, , )];
[backButton addTarget:self action:@selector(popView) forControlEvents:UIControlEventTouchUpInside];
viewController.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithCustomView:backButton];
}
[super pushViewController:viewController animated:animated];
} - (void)popView
{
[self popViewControllerAnimated:YES];
} //手势代理
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
return self.childViewControllers.count > ;
} - (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
} @end
