项目

  • 在项目中我是使用第二篇稳重中的方法,但是具体我还没实现,需要请教大佬
@implementation WoWUpWallpaperViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.title = @"上传壁纸";
    // 点击UIButton AddWallpaper 是打开相册添加图片
    [_AddWallpaper addTarget:self action:@selector(AddWallpaperClick) forControlEvents:UIControlEventTouchUpInside];
    
    // 点击UIButton UpWallPaper 是上传图片
    [_UpWallpaper addTarget:self action:@selector(UpWallpaperClick) forControlEvents:UIControlEventTouchUpInside];
}

# pragma mark -- 添加壁纸
- (void)AddWallpaperClick {
    
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:nil message:@"请选择图片" preferredStyle:UIAlertControllerStyleActionSheet];
    UIAlertAction *OKAction = [UIAlertAction actionWithTitle:@"打开相册" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
        [self openPhotoAlbum];
    }];
    UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:nil];
    [alertController addAction:OKAction];
    [alertController addAction:cancelAction];
    [self presentViewController:alertController animated:YES completion:nil];
}

    QWLog(@"   上传成功啦~~~~~~~ \n成功了?\n\t好像没有\n\t\t真的没有?\n\t\t\temmmmm。。。。   ");
    [self postDataWithUrl:@"http://www.qiangwan.com/index.php?tp=up&op=image" params:nil imageDatas:nil success:^(id response) {
        [QWShowMessage showToastmsg:@"上传壁纸成功"];
    } failure:^(NSError *error) {

    // 1.判断相册是否可以打开
    if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) return;
