使用
在Pods的Podfile里加入：
pod ‘UIAlertView-Blocks’, ‘~> 1.0’
运行命令：
pod update
代码RIButtonItem *cancelItem = [RIButtonItem itemWithLabel:@”No” action:^{the code that will be executed optional… if you leave the action as nil, it won’t do anything// but here, I’m showing a block just to show that you can use one if you want to.}];RIButtonItem *deleteItem = [RIButtonItem itemWithLabel:@”Yes” action:^{the code that will be executed the object in question…[context deleteObject:theObject];}];UIAlertView *alertView = [[UIAlertView alloc] :cancelItemotherButtonItems:deleteItem, nil];[alertView show];
也可以初始化后添加按钮
[alertView addButtonItem:deleteItem];其它问题
我在使用时，提示：
ld: library not found for -lPods-UIAlertView-Blocks clang: error: linker command failed with exit code 1 (use -v to see invocation) (null): Library not found for -lPods-UIAlertView-Blocks (null): Linker command failed with exit code 1 (use -v to see invocation)
处理方法： 把项目和Pods的Architectures设置一致：
在Podfile里加入：
post_install do |installer| installer.project.targets.each do |target| target.build_configurations.each do |config| config.build_settings[‘ARCHS’] = “armv7” end end end
，往往为了自己的不能失败，而处心积虑前怕狼后怕虎，
