iOS 项目日志 -- 密码强度 实现

没有采用Predicate 直接用的是bool值做的

代码如下

@interface ViewController ()<UITextFieldDelegate>

@property (weak, nonatomic) IBOutlet UIProgressView *levelProgress;

@property (weak, nonatomic) IBOutlet UITextField *pwdTextField;

@property (weak, nonatomic) IBOutlet UITextField *confirmPwdTextField;

@property (weak, nonatomic) IBOutlet UILabel *levelLabel;

@end

@implementation ViewController

-(BOOL)judgeWithArray:(NSArray *)arr withPwd:(NSString *)pwd

{

    NSRange range;

    for (int i =0; i<arr.count; i++) {

        range = [pwd rangeOfString:arr[i]];

        

        if (range.location != NSNotFound) {

            return YES;

        }

    }

    return NO;

}

-(void)textFieldDidEndEditing:(UITextField *)textField{

    [self.pwdTextField becomeFirstResponder];

//    NSLog(@"%d",self.pwdTextField.isEditing);

    NSArray* termArray1 = [[NSArray alloc] initWithObjects:@"a", @"b", @"c", @"d", @"e", @"f", @"g", @"h", @"i", @"j", @"k", @"l", @"m", @"n", @"o", @"p", @"q", @"r", @"s", @"t", @"u", @"v", @"w", @"x", @"y", @"z", nil];

    int intResult = 0;

    for (int j = 0; j<arrResult.count; j++) {

        if ([arrResult[j] isEqualToString:@"1"]) {

            intResult ++;

        }

    }

    

    if (intResult <2) {

        self.levelLabel.text = @"弱";

        self.levelProgress.progress = 0.2;

        self.levelProgress.progressTintColor = [UIColor redColor];

    }else if(intResult == 2){
