下载了 xcode beta6, 下载了 ExampleappusingPhotosframework，导入后报 2 个错，苹果的支持范例都不改的吗？

AAPLAssetViewController.m报两个错：
/Users/dxiao/Documents/iOSDev/projects/ExampleappusingPhotosframework/SamplePhotosApp/SamplePhotosApp/AAPLAssetViewController.m:97:29: Incompatible block pointer types assigning to 'PHAssetImageProgressHandler' (aka 'void (^)(double, NSError *__strong, BOOL *, NSDictionary *__strong)') from 'void (^)(BOOL, double, NSError *__strong, BOOL *)'

/Users/dxiao/Documents/iOSDev/projects/ExampleappusingPhotosframework/SamplePhotosApp/SamplePhotosApp/AAPLAssetViewController.m:207:26: No visible @interface for 'PHAssetChangeRequest' declares the selector 'revertAssetToOriginal'

还请过来人给个提醒。

现查API

https://developer.apple.com/library/prerelease/ios/documentation/Photos/Reference/PHImageRequestOptions_Class/#//apple_ref/doc/c_ref/PHAssetImageProgressHandler

接口一样啊。

iOS不提供pre-release的技术支持，把我导向https://devforums.apple.com/index.jspa

錯誤的意思是你正在嘗試給類型不同的block賦值。
而且我能看到pre-release的文檔，你應該是沒有買iOS Developer Program。

[xds2000]

发到apple support 论坛一份，看看有没有人看到。

[xds2000]

@wezzard 我有iOS Developer Program。

解决。
