监听键盘右下角的点击

•通过UITextField的代理方法能够监听键盘最右下角按钮的点击

1.成为UITextField的代理

self.textField.delegate = self;

 

2.遵守UITextFieldDelegate协议,实现代理方法

- (BOOL)textFieldShouldReturn:(UITextField *)textField;

Ø

 

•在UITextField左边放一个view

self.textField.leftView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 8, 0)];

self.textField.leftViewMode = UITextFieldViewModeAlways;
