사용

[FSToast showToast:self messge:@"test !! 1234 124 :Adowefhanweofpin2po3qfinasdfdsflkansdf"];
[FSToast showToast:self 
		messge:@"test !! 1234 124 :\nAdowefhanweofpin2po3qfinasdfdsflkansdf" 
		backgroundColor:UIColor.blueColor 
		duration:1];

응용(복사뒤 토스트)

 

NSString *cpnNO =@"복사할 대상 택스트입니다 ...... ";
UIPasteboard *pb = [UIPasteboard generalPasteboard];
[pb setString:cpnNO];
[FSToast showToast:self messge:cpnNO];

직접 만들어보기

일단은 보여질 view를 구성 스크린 사이즈중 가운데를 알아야한다.

 CGRect mainbounds = UIScreen.mainScreen.bounds;
