图片浏览(双击放大,单击返回)

一个简单实用的图片浏览器,效果类似微信图片浏览器,支持多图浏览,支持本地和网络图片浏览简单介绍一下第三方类:YXBPhotoBrowser   如何添加到项目不再介绍.......

代码如下:

#import "ViewController.h"#import "Masonry.h"#import "YXBPhotoBrowser.h"@interface ViewController ()@property(nonatomic,strong)NSMutableArray *photoArray;

@end

@implementation ViewController

- (void)viewDidLoad {

    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.

    self.view.backgroundColor=[UIColor whiteColor];

    [self ImageBrowsingAddButton];

    [self showPhotoArray];

}

#pragma mark === 图片浏览

-(void)ImageBrowsingAddButton

{

    UIButton *button=[UIButton buttonWithType:UIButtonTypeCustom];

    [button setTitle:@"图片浏览" forState:UIControlStateNormal];

    [button setTitleColor:[UIColor redColor] forState:UIControlStateNormal];

    button.backgroundColor=[UIColor yellowColor];

    [button sizeToFit];

    [button addTarget:self action:@selector(onLookPhotoButton) forControlEvents:UIControlEventTouchUpInside];

    [self.view addSubview:button];

    [button mas_makeConstraints:^(MASConstraintMaker *make) {

        make.top.mas_equalTo(100);

        make.left.mas_equalTo(100);

        make.size.mas_equalTo(CGSizeMake(100, 40));

    }];

}

-(void)onLookPhotoButton

{

    [YXBPhotoBrowser showInWindow:[UIApplication sharedApplication].keyWindow withDelegate:self imageCount:self.photoArray.count currnetIndex:3];

}

#pragma mark ==== 设置图片的浏览

-(void)showPhotoArray

{

    for (int i =0; i<6; i++) {

        UIImage *img=[UIImage imageNamed:[NSString stringWithFormat:@"%d",i+1 ]];

        [self.photoArray addObject:img];

    }

}

-(NSMutableArray *)photoArray

{

    if (!_photoArray) {

        _photoArray=[[NSMutableArray alloc]init];

    }

    return _photoArray;

}

#pragma mark === 图片

- (UIImage *)photoBrowser:(YXBPhotoBrowser *)browser placeholderImageForIndex:(NSInteger)index{

    return self.photoArray[index];

}

#pragma mark === 查看高清图片

- (NSURL *)photoBrowser:(YXBPhotoBrowser *)browser highQualityImageURLForIndex:(NSInteger)index{

    return  [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"%ld",index+1] ofType:@"png"]];

}

- (UIView *)photoBrowser:(YXBPhotoBrowser *)browser containerViewForIndex:(NSInteger)index{

    return nil;

}
