iOS

1、服从协议

UITextViewDelegate, UITextFieldDelegate

1	UITextViewDelegate, UITextFieldDelegate

2、设置代理

3、添加隐藏按钮

void (^addTopView)(UIView *) = ^(UIView *view) {
    UIToolbar *topView = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 35)];
    UIBarButtonItem *flexBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
    UIBarButtonItem *dismissKeyBoardButton;
    dismissKeyBoardButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(dismissKeyBoard)];
    topView.backgroundColor = [UIColor whiteColor];
    NSArray *buttonsArray = @[flexBtn, dismissKeyBoardButton];
    if (view.class == [UITextField class]) {
        ((UITextField *)view).inputAccessoryView = topView;
        topView.items = buttonsArray;
    }
    if (view.class == [UITextView class]) {
        ((UITextView *)view).inputAccessoryView = topView;
        topView.items = buttonsArray;
    }
};
addTopView(self.textField);
addTopView(self.textView);

void (^addTopView)(UIView *) = ^(UIView *view) {

UIToolbar *topView = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 35)];

UIBarButtonItem *flexBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];

UIBarButtonItem *dismissKeyBoardButton;

dismissKeyBoardButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(dismissKeyBoard)];

topView.backgroundColor = [UIColor whiteColor];

NSArray *buttonsArray = @[flexBtn, dismissKeyBoardButton];

if (view.class == [UITextField class]) {

((UITextField *)view).inputAccessoryView = topView;

topView.items = buttonsArray;

}

if (view.class == [UITextView class]) {

((UITextView *)view).inputAccessoryView = topView;

topView.items = buttonsArray;

}

};

addTopView(self.textField);

addTopView(self.textView);

4、添加空白处点击隐藏

UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyBoard)];
tapGestureRecognizer.cancelsTouchesInView = NO;
[self.view addGestureRecognizer:tapGestureRecognizer];

UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyBoard)];

tapGestureRecognizer.cancelsTouchesInView = NO;

[self.view addGestureRecognizer:tapGestureRecognizer];

5、添加键盘隐藏方法

- (void)dismissKeyBoard {
    [self.textField resignFirstResponder];
    [self.textView resignFirstResponder];
}

- (void)dismissKeyBoard {

[self.textField resignFirstResponder];

[self.textView resignFirstResponder];

}

- (void)viewDidLayoutSubviews {
    if ([self.tableView respondsToSelector:@selector(setSeparatorInset:)]) {
        [self.tableView setSeparatorInset:UIEdgeInsetsMake(0,0,0,0)];
    }
    if ([self.tableView respondsToSelector:@selector(setLayoutMargins:)]) {
        [self.tableView setLayoutMargins:UIEdgeInsetsMake(0,0,0,0)];
    }
}
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
    if ([cell respondsToSelector:@selector(setSeparatorInset:)]) {
        [cell setSeparatorInset:UIEdgeInsetsZero];
    }
    if ([cell respondsToSelector:@selector(setLayoutMargins:)]) {
        [cell setLayoutMargins:UIEdgeInsetsZero];
    }
}

- (void)viewDidLayoutSubviews {

if ([self.tableView respondsToSelector:@selector(setSeparatorInset:)]) {

[self.tableView setSeparatorInset:UIEdgeInsetsMake(0,0,0,0)];

}

if ([self.tableView respondsToSelector:@selector(setLayoutMargins:)]) {

[self.tableView setLayoutMargins:UIEdgeInsetsMake(0,0,0,0)];

}

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {

if ([cell respondsToSelector:@selector(setSeparatorInset:)]) {

[cell setSeparatorInset:UIEdgeInsetsZero];

}

if ([cell respondsToSelector:@selector(setLayoutMargins:)]) {

[cell setLayoutMargins:UIEdgeInsetsZero];

}

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    if self.tableview.respondsToSelector("setLayoutMargins:") {
        self.tableview.layoutMargins = UIEdgeInsetsZero
    }
    if self.tableview.respondsToSelector("setSeparatorInset:") {
        self.tableview.separatorInset = UIEdgeInsetsZero
    }
}
func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
    if cell.respondsToSelector("setLayoutMargins:") {
        cell.layoutMargins = UIEdgeInsetsZero
    }
    if cell.respondsToSelector("setSeparatorInset:") {
        cell.separatorInset = UIEdgeInsetsZero
    }
}

override func viewDidLayoutSubviews() {

super.viewDidLayoutSubviews()

if self.tableview.respondsToSelector("setLayoutMargins:") {

self.tableview.layoutMargins = UIEdgeInsetsZero

}

if self.tableview.respondsToSelector("setSeparatorInset:") {

self.tableview.separatorInset = UIEdgeInsetsZero

}

func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {

if cell.respondsToSelector("setLayoutMargins:") {

cell.layoutMargins = UIEdgeInsetsZero

}

if cell.respondsToSelector("setSeparatorInset:") {

cell.separatorInset = UIEdgeInsetsZero

}

「记录」UITableView运行时动态改变行高

iOS隐藏键盘
