BlocksKit 的缺陷
Raw
gistfile1.txt
BlocksKit对原有代码有影响，会导致不用block而用delegate的实现出问题。已经发现不止一次这个缺陷引起的崩溃了。
1. 比如textview点某个词出现系统预置菜单后，点“添加”，会导致“添加”界面的textField意外无限递归而崩溃。
这个问题很恶心啊。设计blocks的时候，似乎没考虑到这点。
2. UIImagePickerViewController的delegate方法必须全实现，否则未选照片时就不能退回。
个人怀疑根源跟method swizzling有关。考虑到method swizzling不被苹果允许，我考虑将项目里的blocksKit相关的代码全删掉。这是无奈之举。毕竟blocksKit确实很优秀。
