UITextField輸入漢字時(shí)，在輸入框會(huì)變成拼音的英文字母。比如輸入chang(長)之后，輸入qi(期)，此時(shí)輸入框會(huì)顯示“長prg期”。通過增加輸入框的監(jiān)聽方法，對輸入內(nèi)容進(jìn)行控制。

#import "ViewController.h"
@interface ViewController ()
@property(nonatomic,strong)UITextField *input;
@end
@implementation ViewController
- (void)viewDidLoad {
    [super viewDidLoad];
   self.input = [[UITextField alloc]initWithFrame:CGRectMake(100, 100, self.view.frame.size.width - 200, 30)];
    _input.backgroundColor = [UIColor yellowColor];
    [self.view addSubview:self.input];
    [self.input addTarget:self action:@selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged];
}
- (void)textFieldDidChange:(UITextField *)textField{
    if (textField.markedTextRange == nil)//點(diǎn)擊完選中的字之后
    {
        NSLog(@"text:%@", textField.text);
    }
    else//沒有點(diǎn)擊出現(xiàn)的漢字,一直在點(diǎn)擊鍵盤
    {
        NSLog(@"markedTextRange:%@",textField.text);
        self.input.text = textField.text;
    }
}
@end

這樣改之后輸入正常。

#import "ViewController.h"
@interface ViewController ()
@property(nonatomic,strong)UITextField *input;
@end
@implementation ViewController
- (void)viewDidLoad {
    [super viewDidLoad];
   self.input = [[UITextField alloc]initWithFrame:CGRectMake(100, 100, self.view.frame.size.width - 200, 30)];
    _input.backgroundColor = [UIColor yellowColor];
    [self.view addSubview:self.input];
    [self.input addTarget:self action:@selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged];
}
- (void)textFieldDidChange:(UITextField *)textField{
    if (textField.markedTextRange == nil)//點(diǎn)擊完選中的字之后
    {
        NSLog(@"text:%@", textField.text);
        self.input.text = textField.text;
    }
    else//沒有點(diǎn)擊出現(xiàn)的漢字,一直在點(diǎn)擊鍵盤
    {
        NSLog(@"markedTextRange:%@",textField.text);
    }
}
@end
