不兼容的塊指針類型| Xcode 6.4

下面的代碼工作正常，直到我將SDWebImage升級到V.3.7.3，現在，它給了我一個錯誤。我把（$$）在開始和這標誌着我的錯誤代碼的結束，這是該行_HUD2 = [General showHUDInView:self.productImageView_下，而實際上從這裏開始：completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType)...不兼容的塊指針類型| Xcode 6.4 | iOS 8.4

錯誤消息告訴你，你試試傳遞錯誤類型的塊：您嘗試

void (^)(UIImage *__strong, NSError *__strong, SDImageCacheType)

而不是正確的

void (^)(UIImage *__strong, NSError *__strong, SDImageCacheType, NSURL *__strong)

區別在於你必須爲NSURL*提供一個地方。他們顯然改變了回調簽名。您必須將您的代碼更改爲

[self.productImageView sd_setImageWithURL:[NSURL URLWithString:[NSString stringWithFormat: IMAGES_PATH , [[_details3 objectAtIndex:0] imagenMuestra]]] placeholderImage:[UIImage imageNamed:nil] completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *url) { 
    [General hideHUD:HUD2]; 
}];

請注意最後一個參數。
