在UISearchBar控件中,是否可以将键盘的“搜索”键标题更改为“完成”?
最佳答案
对于名为表searchbar的搜索栏:
// Set the return key and keyboard appearance of the search bar
for (UIView *searchBarSubview in [tableSearchBar subviews]) {
if ([searchBarSubview conformsToProtocol:@protocol(UITextInputTraits)]) {
@try {
[(UITextField *)searchBarSubview setReturnKeyType:UIReturnKeyDone];
[(UITextField *)searchBarSubview setKeyboardAppearance:UIKeyboardAppearanceAlert];
}
@catch (NSException * e) {
// ignore exception
}
}
}
