Common parsing of IOS NSString APIs

1. Create a constant string.

NSString *astring = @ "This is a string!";

2, create an empty string, give the assignment.

NSString *astring = [[NSString alloc] init]; Astring = @ "This is a 59wan.cn website!"; [Astring release]; NSLog (@ "astring:%@", astring);//nsstring *astring = [[NSString alloc] init]; NSLog (@ "0x%.8x", astring); [Email protected] "This is a string!"; NSLog (@ "0x%.8x", astring); [Astring release]; NSLog (@ "astring:%@", astring);

3, in the above method, lifting speed: Initwithstring method

NSString *astring = [[NSString alloc] initwithstring:@ "This is a string!"]; NSLog (@ "astring:%@", astring); [Astring release];

4. Create a string with standard C: Initwithcstring method

*cstring =; NSString *astring = [[NSString alloc] initwithcstring:cstring]; NSLog (, astring); [Astring release];

5. Create a formatted string: placeholder (composed of one% plus one character)

i =; j =; NSString *astring = [[NSString alloc] initwithstring:[nsstring Stringwithformat:,i,j]]; NSLog (, astring); [Astring release];

6. Create a temporary string

NSString *astring; astring = [NSString stringwithcstring:]; NSLog (, astring);
