makeObjectsPerformSelector 方法的用法

1.mianSc移除所有subviews 这个很不错

[self.mianSc.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)];

2 makeObjectsPerformSelector:@select(aMethod)
简介:让数组中的每个元素 都调用 aMethod

makeObjectsPerformSelector:@select(aMethod) withObject:oneObject

>3简介:让数组中的每个元素 都调用 aMethod 并把 withObject 后边的 oneObject 对象做为参数传给方法aMethod


  /*将检测到的该自动插入的交易插入[数据库]*/
  [array makeObjectsPerformSelector:@selector(setRecurringDelegate:)
                                 withObject:self];
  /*将检测到的该自动插入的交易插入数据库*/
  [array makeObjectsPerformSelector:@selector(insertRecursion)];
