弹出键盘时按钮自动上移

话不多说,上图:





用到了TPKeyboardAvoiding框架,代码如下:

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];

}
