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);
