iOS UITextView 实现placeholder占位符功

简介

我们使用UITextView时，偶会有需要类似UITextField的placeholer的占位符功能， 这里实现了支持placeholder的UITextView, 并且简化设置TextView内边距功能。

代码示例

   KKPlaceholderTextView *testTF = [[KKPlaceholderTextView alloc] initWithFrame:CGRectMake(50, 100, 100, 50)];
   testTF.placeholder = @"请输入描述内容";
   NSDictionary * attributesDic = @{ NSFontAttributeName:[UIFont boldSystemFontOfSize:12],
                                       NSForegroundColorAttributeName:[UIColor redColor]
                                       };
   testTF.attributedPlaceholder = [[NSAttributedString alloc] initWithString:@"请输入描述内容" attributes:attributesDic];
   //  设置textView 内边距
   testTF.padding = UIEdgeInsetsMake(10, 10, 10, 10);
   [self.view addSubview:testTF];
