自定义弹框

1、自定义弹

---

    创建一个继承与NSObject的类CGXAlertController

2、在.h中写

/*

title:            标题

message:          提示语

buttonTitles:      按钮选项数组

completionBlock:  按钮点击返回block

vc:                返回控制器

*/

#pragma mark - 样式选择  返回的有title

+ (void)showAlertViewStyleWithTitle:(NSString*)title message:(NSString*)message buttonTitles:(NSArray*)buttonTitles titleBlock:(void(^)(NSString *titleStr ,NSString *messageStr ,NSString *btntitleStr))titleBlock showViewController:(UIViewController*)vc preferredStyle:(UIAlertControllerStyle)style;

3、在.m中写

static void (^G_completionBlock)(int buttonindex);

#pragma mark - 样式选择  返回的有title

+ (void)showAlertViewStyleWithTitle:(NSString*)title message:(NSString*)message buttonTitles:(NSArray*)buttonTitles titleBlock:(void(^)(NSString *titleStr ,NSString *messageStr ,NSString *btntitleStr))titleBlock showViewController:(UIViewController*)vc preferredStyle:(UIAlertControllerStyle)style{

[CGXAlertController showAlertViewControllerWithTitle:title message:message buttonTitles:buttonTitles showViewController:vc completionBlock:^(NSString *Btntitle) {

if (titleBlock) {

titleBlock(title,message,Btntitle);

}

} cancleBlock:^{

} preferredStyle:style];

}

#pragma mark - 自定义样式

+ (void)showAlertViewControllerWithTitle:(NSString*)title message:(NSString*)message buttonTitles:(NSArray*)buttonTitles showViewController:(UIViewController*)vc completionBlock:(void(^)(NSString *Btntitle))completionBlock cancleBlock:(void(^)(void))cancelBlock preferredStyle:(UIAlertControllerStyle)style{

#ifdef NSFoundationVersionNumber_iOS_8_0

UIAlertController* alert = [UIAlertController alertControllerWithTitle:title message:message preferredStyle:style];

for (NSString* titleStr in buttonTitles) {

UIAlertAction* action;

if ([titleStr isEqualToString:@"取消"] || [titleStr isEqualToString:@"cancel"]) {

action = [UIAlertAction actionWithTitle:titleStr style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {

if (cancelBlock) {

cancelBlock();

}

}];

}else {

action = [UIAlertAction actionWithTitle:titleStr style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {

if (completionBlock) {

completionBlock(titleStr);

}

}];

}

[alert addAction:action];

}

[vc presentViewController:alert animated:YES completion:nil];

#else

G_completionBlock = [completionblock copy];

UIAlertView* alert = [[UIAlertView alloc] initWithTitle:strtitle message:strmessage delegate:self cancelButtonTitle:nil otherButtonTitles:nil];

for (NSString *key in buttontitles) {

[alert addButtonWithTitle:key];

}

[alert show];

#endif

}

#pragma clang diagnostic ignored "-Wdeprecated"

+(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{

if (G_completionBlock) {

G_completionBlock((int)buttonIndex);

}

}
