2. 判断邮箱格式是否正确,利用正则表达式验证

3. 判断字符串中是否含有空格

];
if
(_range.location != NSNotFound) {
return
YES;
}
else
{
return

}
}
4. 判断字符串中是否含有中文

int a = [string characterAtIndex:i];
if
(a > 0x4e00 && a < 0x9fff) {
return

}
}
return

5. 判断字符串是否全部为数字

"[string characterAtIndex:i];"
if

>+ (BOOL)isPureInteger:(NSString *)str {
NSScanner *scanner = [NSScanner scannerWithString:str];

return

6. 过滤一些特殊字符

{
// 定义一个特殊字符的集合
NSCharacterSet *set = [NSCharacterSet characterSetWithCharactersInString:
@
"@/:;: ;()?「」"、[]{}#%-*+=_|~<>$?^?'@#$%^&*()_+'"

}
7. 让iOS应用直接退出
+ (void)backOutApp {
UIWindow *window = [[UIApplication sharedApplication].delegate window];
[UIView animateWithDuration:1.0f animations:^{
window.alpha = 0;
} completion:^(BOOL finished) {
exit(0);
}];
}
8. NSArray 快速求总和、最大值、最小值、平均值
+ (NSString *)caculateArray:(NSArray *)array
{
CGFloat sum = [[array valueForKeyPath:@
"@sum.floatValue"
] floatValue];
CGFloat avg = [[array valueForKeyPath:@
"@avg.floatValue"
] floatValue];

"@min.floatValue"
] floatValue];
NSLog(@
"%fn%fn%fn%f"
,sum,avg,max,min);
return
[NSString stringWithFormat:@
"%f"
,sum];
}
9. 验证身份证
+ (BOOL)checkIdentityCardNo:(NSString*)value {
value = [value stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
NSInteger length =0;
if
(!value) {
return
NO;
