在输入价格的时候,要求弹出的键盘只能有数字和小数点。弹出的键盘没有完成键,想要退出键盘可以点击退出,但是为了更好的用户体验,在键盘上增加UIToolbar。
设置ToolBar:
- (UIToolbar *)addToolbar { UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(, , CGRectGetWidth(self.view.frame), )];
toolbar.tintColor = [UIColor blackColor];
toolbar.backgroundColor = [UIColor lightGrayColor];
UIBarButtonItem *prevItem = [[UIBarButtonItem alloc] initWithTitle:@" < " style:UIBarButtonItemStylePlain target:self action:@selector(prevTextField:)];
UIBarButtonItem *nextItem = [[UIBarButtonItem alloc] initWithTitle:@" > " style:UIBarButtonItemStylePlain target:self action:@selector(nextTextField:)];
UIBarButtonItem *flbSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *doneItem = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"完成",nil) style:UIBarButtonItemStylePlain target:self action:@selector(textFieldDone)];
toolbar.items = @[prevItem,nextItem,flbSpace, doneItem];
return toolbar;
}
为textField添加ToolBar:
_textField.inputAccessoryView = [self addToolbar];
