弹出键盘时按钮自动上移

话很少说,上图:

用到了TPKeyboardAvoiding框架,代码以下:

在viewController中:

#import "ViewController.h"

#import "TPKeyboardAvoidingScrollView.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {

    [super viewDidLoad];

    TPKeyboardAvoidingScrollView *scrollview = [[TPKeyboardAvoidingScrollView alloc]initWithFrame:self.view.frame];

    UITextField *textField = [[UITextField alloc]initWithFrame:CGRectMake(100, 500, 100, 100)];

    textField.backgroundColor = [UIColor redColor];

    [scrollview addSubview:textField];

    [self.view addSubview:scrollview];

    

}
